Three things decide a deck quote, and none is timber preference: what it attaches to, what holds it up, and whether anyone needs to approve it. A quote that handles those three well will close regardless of length. One that does not will lose the job or win the wrong version of it.
The failure mode worth naming up front: a deck is a structure that people stand on, and its connection to the house is the part that fails when done badly. Any writing touching that connection has to defer to the applicable code and the person qualified to specify it.

Writing the material comparison
Customers ask for "composite versus timber" and expect a recommendation. The honest comparison is three columns and four rows: upkeep required, expected lifespan, how it weathers, and cost. No winner — the right answer depends on whether the owner wants to maintain anything.
State plainly what each will look like in five years. Composite greys less and cleans differently; timber greys, moves and can be refinished. Describing how each ages is more useful than ranking them, and it reduces the number of customers who discover the change later and treat it as a defect.
Where they failed
The ledger connection. This is the one that matters most and the one generated text handles worst. How a deck attaches to a house involves flashing, the condition of the existing structure, and code requirements that differ by location. Frame it, never specify it: say that the attachment is detailed to the applicable code and, where the condition requires it, that a structural professional specifies the connection.
Footings and ground. Footing depth and type depend on frost depth, soil bearing capacity and local practice — all site-specific, all outside what a generator knows. State that footings are sized to the applicable code and inspected where inspection applies, and name who confirms.
Permits. Generated text tends to write "all permits included" as though there were one global answer. Sometimes a permit is needed, sometimes exempt below a stated height or area, sometimes it is the owner's application. State whose responsibility it is for this job and name the authority to confirm with rather than asserting a rule.
Weight and load. Hot tubs, planters and pergolas change the load case substantially. Any quote involving them should say the structure is being designed for that load, and that hot tub installation follows the manufacturer's requirements and the applicable code.
Maintenance honesty
Every deck requires something, and the two SDS-worthy points are: timber needs refinishing on a stated cycle, and no deck is maintenance-free whatever its material — cleaning, drainage clearance and periodic checks still apply. Writing this into the quote rather than the handover is what prevents the year-three complaint.
Worth one sentence on gaps between boards and colour change: both surprise customers who have only seen showroom samples.
Two cautions for structural components
Where a load-bearing element is involved — post sizing, beam span, joist spacing — the dimensions come from the applicable code or from drawings prepared by the professional responsible for them, not from a template and not from an estimate of what looks sufficient. Say in the quote which source applies and who supplies it. Requirements differ between jurisdictions and between the governing code versions, so name the authority to confirm with rather than stating a figure.
Stairs, rails and the parts customers underestimate
Stairs and guardrails attract more regulation per metre than any other part of a deck, and they are regularly under-scoped in early conversations. Grip height, baluster spacing and stair geometry are all governed by requirements that vary by location, and getting them wrong means rebuilding rather than adjusting. Write them into the quote as items designed to the applicable code, name who confirms compliance, and price them properly rather than as afterthoughts.
Editing time, from our 30-day benchmark
Enquiry replies and follow-ups: 2–4 minutes. Material sheets and maintenance sections: 5–8 minutes. Anything touching the house attachment, footings, permits or added load: 8–12 minutes, essentially all of it replacing confident specification with correct deference. That time is not optional in this trade.
Frequently Asked Questions
Do I need a permit to build a deck?
It depends on height, size, attachment and location, and exemptions differ widely between authorities. Name the relevant authority in your quote and state whose responsibility the application is rather than assuming the answer.
Can these tools write a deck quote?
The structure and the material comparison, yes. Every figure — dimensions, material, footing basis — has to be yours, as does anything about permits or structural attachment, where deference to the applicable code is the correct response.
How should I present composite versus timber?
As a comparison rather than a recommendation: upkeep, expected life, how it weathers, cost. Include what each looks like after several years, which prevents most later disappointment.
Is it safe to say maintenance-free?
No material makes that true. Say what each option actually requires and how often, in the quote rather than the handover, and the resulting expectations will match the deck that gets delivered.
What about adding a hot tub later?
It changes the load case fundamentally and should be designed in from the start, never added to an existing deck without assessment. State that installation follows manufacturer requirements and the applicable code.
