The short answer first
Ask every builder the same set of questions, write the answers down, and sign nothing until the answers are in the contract. The questions that matter most cover licence and insurance, who handles permits and inspections, what the written estimate itemises, what the contract actually promises, who will be on site, which materials will be used by name and grade, how delays and clean up are handled, and what warranty on workmanship is offered in writing. Pressure to decide at once is itself a warning sign in Erie County consumer protection guidance, shared on the Erie County consumer protection page, so a builder who answers calmly and in writing has already told you something useful.
Licence, insurance and who checks them
Start with standing, not boards. Ask: are you licensed for this work here, and are you insured? Then ask how you can check.
Erie County consumer protection guidance says to consider only contractors who are licensed and insured, check the licence with state or county government, and ask for proof of insurance Erie County home improvement guidance.
The same guidance says to get recommendations from people you know and trust, and to check with the local Home Builders Association and consumer protection officials for complaints Erie County home improvement guidance.
So ask the builder for recent customers you can contact, and ask neighbours or friends who built a deck who they used. Note the licence number and insurer details, and keep them with the contract if you sign. If a builder cannot produce either document, stop there and talk to someone else.
Permits and inspections: who applies
Next, ask who applies for permits and who deals with inspections. This question sorts builders quickly.
Erie County consumer protection guidance lists a contractor asking the homeowner to get the required building permits as a warning sign Erie County home improvement guidance.
So if a builder tells you to pull the permit yourself, ask why, and be cautious. Also ask which inspections the job needs, at what stages they happen, and who will be present when the inspector calls.
Add two technical questions here. Ask which guide or code the framing follows. The American Wood Council guide DCA 6 covers single level residential wood decks, and its joist spans assume 40 psf live load and 10 psf dead load AWC DCA 6 guide. Ask how guard posts will be attached to the frame.
The written estimate, line by line
Ask for the estimate in writing, and ask what each line covers. Erie County consumer protection guidance says to get multiple estimates, and that a written estimate should include a description of the work, materials, a completion date and the total for the job Erie County home improvement guidance.
Ask what is left out. Ground work, steps, guards, removal of an old deck and site clean up are common gaps between a headline figure and the finished job.
The same guidance says not to automatically choose the lowest bidder, and to ask for an explanation when estimates differ a lot Erie County home improvement guidance.
Compare estimates against the deck building scope so you are judging the same job each time.
The contract: read every line before signing
When the estimate becomes a contract, slow down. Erie County consumer protection guidance says to read the contract carefully, and that it should include the contractor name, address, phone number and licence number, an estimated start and completion date, any promises made about scope, and the cost of labour and materials Erie County home improvement guidance.
Ask about anything that was promised in conversation but is missing on paper. If a promise matters, it belongs in the contract. Ask about blank spaces too: the same guidance says all blank spaces should be filled in, so query any gap before you sign rather than after.
The contract should also include a written statement of the right to cancel within three business days when the contract was signed at home Erie County home improvement guidance. Ask where that statement sits in your copy.
Finally, ask about timing of amounts due. Do not hand over the full amount up front, note that some states limit what can be asked for at the start, and never hand over the final amount until the work is done and you are satisfied Erie County home improvement guidance.
People, materials and daily site life
Ask who will actually be on site each day, and who supervises them. Ask who you call when something looks wrong, and ask for that name to be written on the contract paperwork.
Then turn to materials. Ask for board, post and fixing types by name and grade, not by broad labels. Ask where materials will be stored, and what happens if a named material is unavailable.
Our how it works page explains how a DeckNear referral reaches a local provider, so you know who is responsible for these answers.
Timing, delays, clean up and warranty
Close with time and aftercare. Ask for a start date and a completion date in writing, and ask what counts as a weather delay and how you will be told about one.
Ask what clean up is included at the end: offcuts, fixings, soil from footing holes and the old deck, if one is being removed.
Ask what warranty covers workmanship, how long it runs, what it excludes and how a claim is made. Ask for that warranty in writing, signed, with the builder details on it. A verbal promise at the door is hard to use a year later.
Ask the same questions of every builder, keep the written answers together, and compare them in one sitting. Start from our home page to request a referral once you are ready to ask them.
Frequently asked questions
Should I check a deck builder licence myself?
Yes. Erie County consumer protection guidance says to consider only contractors who are licensed and insured, and to check the licence with state or county government and ask for proof of insurance. A builder who expects that check will hand over the details without argument. Write the licence details down and keep them with your copy of the signed contract.
Who should apply for the deck permit?
Ask the builder directly, and treat the answer as a test. Erie County consumer protection guidance lists a contractor asking the homeowner to get the required building permits as a warning sign. Reputable builders normally handle applications for work they design and build. Whoever applies, agree in writing who books inspections and who fixes anything an inspector asks to change.
What should a written deck estimate include?
Erie County consumer protection guidance says a written estimate should include a description of the work, the materials, a completion date and the total for the job. Get estimates from more than one builder, compare them line by line, and do not automatically choose the lowest. When figures differ a lot, ask each builder to explain the gap in writing.
When should I hand over the final amount?
Erie County consumer protection guidance is clear: do not hand over the full amount up front, and never hand over the final amount until the work is done and you are satisfied. Agree what is due at each stage before signing, and link each stage to finished work you can see and check, such as a passed inspection or completed framing.
