# What Should a Greenhouse Quote Include Before You Pay a Deposit?

The 21-line checklist for a complete greenhouse quote: deposit terms, freight liability, the inspection window, and the warranty schedule nobody puts on the product page. Checked August 22, 2026.

## Quick answer

A complete greenhouse quote states 21 things in writing: the exact structure and glazing spec, vent area as a percent of floor area, the base spec the warranty requires, who owns the freight and who signs the bill of lading, the inspection window for transport damage, the assembly scope, the warranty schedule by component, and the payment terms including what a deposit forfeits on cancellation. Checked August 22, 2026, only one maker in this niche, Hartley Botanic, publishes its deposit and cancellation terms in writing: 50 percent on order, the balance 48 hours before delivery, and the deposit is forfeit once production starts. Alitex, Exaco (Riga and Janssens), and Palram/Canopia publish no deposit percentage at all, which means the schedule you get is the only one that exists and it belongs in writing before you pay it.

Nobody's product page tells you who signs the bill of lading. Nobody's dealer listing says what a deposit forfeits if you cancel after the crate is already built. Every brand in this niche, from a $3,500 Palram kit to a $60,000 Alitex, sells you a structure and leaves the actual purchase terms, the deposit, the freight liability, the inspection window, to a sales conversation that happens after you have already picked a favorite.

We checked what the makers themselves publish, on August 22, 2026. The finding is not a list of hidden fees. It is a list of blanks. One maker in this comparison, Hartley Botanic, prints its deposit, balance, and cancellation terms in a numbered contract clause anyone can read before calling. Alitex, Exaco (which sells both Riga and Janssens), and Palram/Canopia publish none of it. That gap is not proof of bad faith, a bespoke or dealer-sold product is allowed to quote per order, but it does mean the schedule you are quoted is the only version that exists, and the only record of it is the one you get in writing.

We don't sell greenhouses. We save you from buying the wrong one. This is the checklist to run before the deposit leaves your account, built from the terms of sale, warranty documents, and freight policies the sellers themselves publish, not from a generic buying-guide template.

## Quick Answer: Pass or Hold

| If the quote... | Verdict |
|---|---|
| States glazing thickness in mm, vent count, and a base spec, with a payment schedule in writing | Pass |
| States a kit price and "shipping included" with no freight-liability or inspection language | Hold, ask the freight questions below before you pay |
| Has no documented wind/snow rating and no base spec | Hold, see the red flags below |
| Discount expires tonight, or the deposit schedule is verbal only | Hold, real quotes do not need urgency to close |
| Comes from Hartley Botanic | The deposit and cancellation terms are already published; confirm the lead time and dwarf-wall drawings instead |

## How This Checklist Was Built

Checked **August 22, 2026**. We read the published terms of sale, warranty documents, and freight or shipping policy pages for the brands this site covers most, not a single generic e-commerce template. Where a manufacturer publishes nothing, the row says so and names what a specialist greenhouse retailer publishes instead, because that is the closest real-world analog a buyer can check today.

- **Deposit and cancellation terms:** [Hartley Botanic's own Terms and Conditions of Sale](https://hartley-botanic.com/terms-conditions-sale/), clauses 2.6, 2.8, 3.10, 5.2, 5.4, 5.9, and 5.15, the only fully numbered contract terms published by any maker in this comparison.
- **Freight and damage-claim practice:** the published shipping and return policies of two specialist greenhouse retailers, [Greenhouse Megastore](https://www.greenhousemegastore.com/pages/return-policy) and [The Greenhouse Company](https://www.thegreenhousecompany.net/terms-of-service-and-refund-policy/), plus the federal floor under the Carmack Amendment (49 U.S.C. § 14706) and standard LTL freight practice.
- **Warranty schedules:** the manufacturer warranty documents already verified for [Palram, Exaco Riga, and Janssens](/guides/palram-vs-exaco-riga-vs-janssens), and the guarantee terms published by [Hartley Botanic](/guides/hartley-botanic-greenhouse-cost) and [Alitex](/guides/alitex-greenhouse-cost).
- **Vent area, base, anchoring, and permit guidance:** our own published planning material in [ventilation and overheating](/guides/greenhouse-ventilation-overheating), [the foundation and base guide](/guides/greenhouse-foundation-base-guide), [wind and anchoring](/guides/greenhouse-wind-anchoring), and [do I need a permit](/guides/do-i-need-a-permit-for-a-greenhouse).

We have not requested or reviewed a private quote from any of these sellers for this page. Every figure below comes from a document the seller or a specialist retailer has published, and it is labeled as such. Reddit and forum searches for this specific topic, quote deposits and freight claims, were attempted and returned nothing usable this run, so the FAQ below uses sourced buyer questions rather than invented verbatims.

## The Master Quote Checklist

Twenty-one lines. A seller who has done this before answers all of them without a follow-up call. Credit anything already in writing on the manufacturer's own site; do not credit a verbal "don't worry about that."

| # | Line item | What a complete quote states | What sellers usually leave out | Who owns it |
|---|---|---|---|---|
| 1 | Structure and glazing spec | Model name, frame material and gauge, glazing type and thickness in mm | A photo and a size, no gauge or mm figure | Manufacturer |
| 2 | Floor area and footprint | Exact dimensions, not "approx." | Marketing footprint that excludes gutters or vestibules | Manufacturer |
| 3 | Included vents and vent area | Vent count, and vent area as a percent of floor area against the 15-20% ASABE guideline | Vent count only; none of Palram, Exaco Riga, or Janssens publishes vent area in square feet | Manufacturer |
| 4 | Automatic openers | How many ship in the box versus cost to add | Openers shown in a photo but priced as an accessory | Manufacturer/dealer |
| 5 | Base and foundation spec | The exact base the warranty requires: material, depth, tolerance | "Level, prepared surface," no tolerance or material spec | Manufacturer |
| 6 | Anchoring hardware | Included or sold separately, engineered for your base type | Assumed included, actually a separate SKU | Manufacturer/dealer |
| 7 | Freight ownership (F.O.B. terms) | Who owns the goods once they leave the factory or dock | Silent; buyer assumes the seller is liable until arrival | Manufacturer |
| 8 | Delivery type | Liftgate, curbside, or placed in the yard, named explicitly | "Delivery included," no detail on how far the crew goes | Freight carrier/dealer |
| 9 | Inspection window before signing | The right to inspect before signing the delivery receipt, and to write "subject to inspection" if the driver won't wait | Never mentioned; assumed the buyer just signs | Buyer |
| 10 | Concealed-damage reporting window | A stated number of days to report damage found after unboxing | No number given, or a shorter carrier-specific window buried in fine print | Buyer |
| 11 | Assembly scope | Full build, partial, or owner labor, stated as a line item | "Easy weekend assembly," no defined scope | Manufacturer/installer |
| 12 | Glass or pane breakage liability during assembly | Who pays if a pane cracks during the build | Not addressed in any published document we found | Manufacturer/installer |
| 13 | Electrical and water hookup | Explicitly excluded, licensed local trade required | Implied as simple, no mention of permits or a licensed trade | Buyer/licensed trade |
| 14 | Permit responsibility | Buyer confirms local code and setbacks before ordering | Not mentioned; assumed exempt | Buyer |
| 15 | Warranty component schedule | Frame, glazing, and workmanship years, stated separately | A single headline number ("10-year warranty") with no per-component breakdown | Manufacturer |
| 16 | Warranty proration | Whether cover shrinks over time and the year-by-year schedule | "Prorated after year five," no published ladder (Exaco's own language) | Manufacturer |
| 17 | Warranty transferability | Stated as transferable or not on a house sale | Silent; assume non-transferable unless stated, which matches every brand we checked | Manufacturer |
| 18 | Replacement panel or pane price | A current price and lead time for a cracked panel | Not published by Palram, Exaco Riga, or Janssens as of August 2026 | Manufacturer |
| 19 | Parts channel and lead time | Which entity ships parts in year six and how long it takes | Assumed "the manufacturer," no named US contact | Manufacturer |
| 20 | Payment schedule | Deposit percent, balance trigger, and what cancellation forfeits | Only Hartley Botanic publishes this; every other brand here quotes it per order | Manufacturer/dealer |
| 21 | Final scope reconciliation | The delivered invoice matches the written quote, line by line, before final payment | Assumed automatic; verbal add-ons during the build are the most common source of disputed final invoices | Buyer |

Rows 3, 16, 18, and 20 are the ones this niche's own product pages fail most often, which is exactly why a model or a buyer searching for "what should a greenhouse quote include" finds a retailer's generic template instead of brand-specific answers.

## Deposit and Payment: What Is Actually Documented

This is the gap the rest of the industry has not closed. Checked August 22, 2026, across the five brands this site covers most closely.

| Brand | Deposit documented? | Balance and cancellation terms | Source |
|---|---|---|---|
| Hartley Botanic | Yes, 50% of the order total | Balance due at least 48 hours before delivery. Cancel before production starts and Hartley keeps the 50% deposit; cancel after production starts and Hartley "reserve[s] the right to retain the entire deposit paid." | Hartley Botanic Terms and Conditions of Sale, clauses 2.6, 2.8, 3.10 |
| Alitex | No | Not published on Alitex's pricing or terms pages; the design-visit process implies a per-order schedule | Alitex greenhouse pricing policy; no deposit clause found on alitex.co.uk |
| Janssens (via Exaco) | No | Not published on exaco.com; handled at order time through the dealer or Exaco directly | exaco.com, checked August 2026, no deposit terms published |
| Exaco Riga | No | Same as Janssens; both sold through Exaco | exaco.com, checked August 2026 |
| Palram/Canopia | No | Sold entirely through dealers; Palram publishes no direct-to-consumer deposit schedule | canopia.com, checked August 2026, no deposit terms published |

Hartley's own clause is worth reading in full before you sign anything premium-tier: production begins only after the 50 percent deposit clears, and clause 2.8 draws a hard line at that point, cancel before production and you forfeit half your deposit, cancel after and the company can keep all of it. That is a real, binding number, and it is also the reason to ask exactly when "production" starts on your order, in writing, before you pay the deposit.

For the four brands that publish nothing, the honest read is not that the terms are hidden. Retail-direct manufacturers with no consumer deposit and dealer-sold kits both settle payment terms per order, which is normal for the industry. What is not normal is leaving that schedule verbal. Ask for the deposit percentage, the balance trigger, and the cancellation terms in the same email that confirms your model and price, and get the answer in writing before you pay anything.

## Freight and Damage: Who Signs, Who Claims, How Long You Have

Every greenhouse in this niche above flat-pack size ships by LTL freight, a pallet or crate handed to a trucking company, not a parcel carrier. That single fact creates a liability chain most buyers have never navigated, and it is the line nobody's product page explains.

**Title and risk pass at delivery, not at your door.** [Greenhouse Megastore's own return policy](https://www.greenhousemegastore.com/pages/return-policy) states it plainly: "Title to all goods pass to the buyer upon receipt of shipment by the buyer or buyer's agent," and from that moment, "it is the buyer's responsibility to file a freight claim with the carrier if the carrier fails to deliver the goods complete and in good condition." Hartley Botanic's own contract says the same thing in clause 5.9: "You are responsible for the Goods when delivery has taken place. The risk in the Goods passes to you when delivery of the Goods is made to you."

**You have the right to inspect before you sign, and you should use it.** The freight industry's own guidance is consistent: write "subject to inspection" or "pending further inspection" on the delivery receipt if the driver will not wait for you to check the crate, because that notation is what preserves your claim if damage turns up once you open it. Note any visible damage on the bill of lading itself; an unmarked signature is read as acceptance.

**Concealed damage has a reporting window, and it is short.** [The Greenhouse Company's](https://www.thegreenhousecompany.net/terms-of-service-and-refund-policy/) published terms require that "concealed or hidden damages must be reported to the shipping company within 5 days of delivery." Freight-industry guidance more broadly puts the window at five to fifteen days depending on the carrier, and some carriers cut it to 48 hours. Ask your seller which carrier they use and what that carrier's window actually is, because "shipping included" tells you nothing about it.

**Federal law sets a floor, not a fast lane.** Under the Carmack Amendment (49 U.S.C. § 14706(e)(1)), a motor carrier cannot require a formal written claim to be filed in less than 9 months from delivery, and cannot require a lawsuit in less than 2 years from a written claim denial. That is a legal minimum for the formal claim, not a substitute for reporting damage immediately. Report it fast, document it well, and use the 9-month figure only as the outer legal boundary, not the plan.

**Get this in writing before the crate ships, not after it arrives damaged:**
- Which carrier delivers, and that carrier's specific concealed-damage window
- Whether delivery is liftgate, curbside, or placed, and who carries crates from the curb to the build site
- Who reorders a cracked pane or a bent frame section, and at what price, since none of Palram, Exaco Riga, or Janssens publishes a replacement-panel price today

## Warranty by Component

Headline years hide the schedule. Read side by side, checked against the same documents used in [our Palram vs Exaco Riga vs Janssens comparison](/guides/palram-vs-exaco-riga-vs-janssens) and the [Hartley](/guides/hartley-botanic-greenhouse-cost) and [Alitex](/guides/alitex-greenhouse-cost) cost guides.

| Brand | Frame | Glazing | Proration | Transferable |
|---|---|---|---|---|
| Palram/Canopia | 10 years | 10 years | Yes, 10% more of original price per year, reaching 90% in year 10 | No |
| Exaco Riga | Up to 15 years | Up to 10 years | Yes, "prorated beginning 5 years," no published ladder after that | No |
| Janssens | Up to 15 years | Excluded from day one | Not applicable, glass is not covered at all | No |
| Hartley Botanic | 30 years structural | 30 years structural | Not prorated; some components carry shorter listed terms | No |
| Alitex | 25 years or lifetime of purchaser, whichever is longer | Same frame term; paint 10 years conditional on annual washing | Not prorated on the frame | No |

All five are non-transferable. If you sell the house, none of these warranties follows the greenhouse to the new owner, in every published document we checked.

## Red Flags: One-Line Tests

Each of these is a reason to pause the order, not necessarily to cancel it. Ask the question, get it in writing, then decide.

- **No documented wind or snow rating.** If it is not written down with a psf or mph figure and a source document, it is not rated. See [greenhouse snow load](/guides/greenhouse-snow-load) and [wind and anchoring](/guides/greenhouse-wind-anchoring) for how to check your own address against ASCE 7.
- **No base spec in the quote.** A quote for a structure with no base spec is a quote for a kite, not a greenhouse.
- **The discount expires tonight.** Real quotes do not need artificial urgency, and greenhouse promo cycles repeat.
- **A verbal delivery promise with no lead time in writing.** Hartley's own contract states a typical 13-week lead time and what happens if it slips past 30 days late (a refund or cancellation option). If a seller cannot say something similarly concrete, ask why.
- **No named installer or assembly crew for a paid-assembly order.** "We'll arrange someone" is not a name, a license, or a scope of work.
- **Freight described only as "included," with no carrier named and no damage-claim language.** That is the line most buyers lose money on, and it is nowhere on a brochure.
- **A payment schedule given verbally, with nothing in the order confirmation.** Hartley's own numbered clauses show what a real payment schedule looks like in writing; anything you get should be at least that specific.

## The Pre-Deposit Checklist to Send

Copy this into an email to the seller before you pay a deposit. A credible seller answers all of it without deflecting.

1. What is the vent area as a percent of floor area, and what does an additional vent cost installed?
2. What is the exact base spec required for the warranty to remain valid?
3. Who owns the freight in transit, and what is the carrier's specific window for reporting concealed damage?
4. What is the delivery type: liftgate, curbside, or placed, and who carries the crates the rest of the way?
5. What is the assembly scope, and who is liable if a pane cracks during the build?
6. What is the warranty schedule by component: frame, glazing, and workmanship, prorated or not, and is it transferable?
7. What is the current replacement price and lead time for one panel or pane?
8. What is the payment schedule: deposit percent, balance trigger, and what does cancellation forfeit at each stage?
9. What is the lead time from order to delivery, in writing, and what happens if it slips?

If the answers come back solid, that is a pass. If half of them come back "don't worry about that," treat it as a hold, not a signature.

## What We Could Not Verify

Publishing the gaps is more useful than guessing past them. As of August 22, 2026:

- **Deposit percentages for Alitex, Exaco (Riga and Janssens), and Palram/Canopia.** None publishes one. Hartley Botanic is the only brand in this comparison with a numbered, public deposit and cancellation clause.
- **Glass or pane breakage liability during professional assembly, for any brand.** No published document we found addresses this directly; it belongs on the pre-deposit email, not assumed either way.
- **A specific concealed-damage reporting window from Palram, Exaco, or Alitex directly.** The 5-day figure in this guide comes from two specialist greenhouse retailers' own published terms, not from a manufacturer document, and carrier-specific windows can be shorter.
- **Replacement panel or pane prices for Palram, Exaco Riga, or Janssens**, consistent with what we found building [the three-way comparison](/guides/palram-vs-exaco-riga-vs-janssens): none publishes one.
- **A verbatim buyer question from Reddit or a gardening forum specific to deposits or freight claims.** Searches for this topic returned nothing usable this run; the FAQ below is built from the sourced material above, not an invented quote.

We have not requested a private quote from any of these sellers, and this checklist is not a substitute for reading your own contract in full.

## Frequently Asked Questions

### What should a complete greenhouse quote include before I pay a deposit?

At minimum: the exact structure and glazing spec with glazing thickness in mm, vent area as a percent of floor area, the base spec the warranty requires, who owns the freight and the carrier's damage-reporting window, the assembly scope, the warranty schedule broken out by component with proration and transferability stated, and the full payment schedule including what a deposit forfeits on cancellation. Checked August 22, 2026, only Hartley Botanic publishes all of the payment terms in writing; every other brand in this comparison quotes them per order, which makes getting them in writing your job, not theirs.

### How much deposit does a greenhouse maker usually require?

There is no published industry standard. Hartley Botanic is the only brand here with a numbered public clause: 50 percent on order, the remaining 50 percent at least 48 hours before delivery, and the deposit is forfeit in part or in full if you cancel once production has started. Alitex, Exaco (for both Riga and Janssens), and Palram/Canopia publish no deposit percentage, so the number you are quoted is set per order and exists only in your written confirmation.

### Who is responsible if my greenhouse arrives damaged on the freight truck?

You are, procedurally, even though the carrier or the maker ultimately pays. Title and risk typically pass to the buyer at delivery, both Hartley Botanic's own contract and Greenhouse Megastore's published return policy state this directly, so it is the buyer's job to inspect before signing, note any visible damage on the bill of lading, and report concealed damage within the carrier's stated window, commonly five to fifteen days per general freight-industry guidance, sometimes as little as 48 hours depending on the carrier. Federal law under the Carmack Amendment sets a 9-month minimum for filing a formal claim, but that is a legal floor, not a reason to wait.

### What happens if I cancel my greenhouse order after paying a deposit?

It depends entirely on the brand, and only one publishes the answer. Hartley Botanic's contract states that canceling before production starts forfeits the 50 percent deposit, and canceling after production has started lets the company keep the entire deposit paid. No other brand in this comparison publishes a cancellation clause, so ask for the cancellation terms in writing at the same time you ask for the deposit percentage, before you pay anything.

### Does a longer warranty always mean better coverage?

No. A 15-year frame warranty on an Exaco Riga and a 15-year frame warranty on a Janssens sound identical until you read the glazing line: Riga's twin-wall glazing is covered up to 10 years, prorated from year five, while Janssens excludes its own tempered glass from warranty on day one. Palram's 10-year warranty publishes the clearest proration ladder of the three, and it is also the least generous: a claim in year six costs 50 percent of the part's original price. The headline number is marketing. The component-by-component schedule is the actual coverage.
