What should a deck proposal or estimate include before I sign anything?
Short answer
A good deck proposal is specific enough that two builders reading it would build the same deck. It should name the decking product, color and fastener system; describe the framing, footings, ledger attachment and flashing; show the railing and stair design; state who is pulling the permit; list what is excluded; give a payment schedule tied to milestones and a realistic timeline; and spell out warranties on labor and materials. If any of that is a single line or missing, ask for it in writing before you commit.
A drawing, not just a description
The first thing a proposal should include is a plan: a scaled drawing showing the deck's size, shape, height, stairs, railing and any pergola or bench, placed on the lot with distances to the house and property lines. A section through the deck showing footings, posts, beam, joists and decking is the second. Twenty years in architecture taught us that a drawing settles more arguments before they start than any paragraph can, and the city will want these for the permit anyway. If a proposal is a page of text with a number at the bottom, you are being asked to buy something that has not been designed yet.
Materials, named
Vague lines like composite decking or pressure-treated frame are where disputes grow. Ask for the exact product; samples should be part of the conversation.
- Decking: manufacturer, product line, profile, color, and the fastener system; or for wood, species, grade and thickness.
- Framing: lumber species and treatment rating, joist size and spacing, beam size, post size.
- Footings: type, size and depth, and whether the soil has been looked at.
- Ledger: how it attaches to the house, what fasteners, and how it will be flashed; or a note that the deck is freestanding.
- Hardware: hot-dip galvanized or stainless, and which where.
- Railing: material, style, post attachment method, height and infill.
- Stairs: number of risers, tread material, handrail, landing.
- Finish: product and number of coats for wood; cleaning and warranty notes for composite.
Permits, code and who is responsible
The proposal should say whether the deck requires a permit, who will apply for it and who pays the fees, and that the design meets the current California Residential Code for guards, stairs, footings and ledgers. It should also note anything site-specific: Coastal Zone review in parts of Carlsbad, fire hazard zone material requirements, HOA approval. If you are told a permit is not needed, that should come with the reason, and you can confirm it yourself with the Carlsbad Building Division.
On who you hire: California law sets out when a person performing construction work must hold a state license and what consumers should check before hiring. The Contractors State License Board publishes that guidance and a free license lookup. We give every client that link and encourage them to read it, because it is their protection and it is better stated by the agency than paraphrased by us.
Scope, exclusions and the things that go wrong
A proposal should list what is not included as clearly as what is: demolition and haul-away of the old deck, repairs to the house if rot is found behind the ledger, electrical for lighting, irrigation relocation, landscaping restoration, painting the house where the old deck was. It should also explain how unforeseen conditions are handled, usually by a written change order with a price before the work proceeds. On resurfacing jobs especially, finding a rotted ledger is common, and the proposal should say what happens then.
Timeline matters: a start window, a working estimate of duration, and what could move it, such as permit review time or material lead times. Composite colors and hardwoods can take weeks to arrive.
Payment, warranty and the paperwork
Payments should be tied to milestones you can see: footings poured, framing complete, decking complete, final. California law limits what can be requested as a down payment on a home improvement contract and requires certain notices in the contract itself; the Contractors State License Board's consumer pages describe those protections. A proposal should state the labor warranty in plain terms and pass through the manufacturer's material warranties, with a note on what voids them, such as sealed skirting under composite.
Finally, look for the person, not just the paper. Ask to see finished work and to talk to the people who live with it. On the composite deck and pergola we built in North County, the proposal was a drawing of the two structures as one composition before it was a number, which is how we think every deck should start.
Related questions
Should I get more than one deck proposal?
Yes, and compare them line by line on the items above rather than on the bottom line alone. A proposal that names every product and detail is bidding a different, and usually better, deck than one that does not.
Is it normal for a builder to charge for a design?
It is common for a scaled design and permit drawings to be a paid first step, sometimes credited toward the build. A design you own lets you compare bids on the same deck and protects you if you change builders.
What if the proposal does not mention a permit?
Ask. If the deck is attached, raised or has stairs off a required exit door, it almost certainly needs one in Carlsbad. A proposal silent on permits should be clarified in writing before you sign.
