A siding job goes well when key points are settled in writing before the first board comes off. The questions below help you test credentials, compare estimates on equal terms, and avoid gaps around permits, crew identity, cleanup, and warranty coverage. Take notes and keep every answer with the contract.

Start with credentials you can verify
Ask for the legal name of the firm, the name of the person who will sign the contract, and the license number for the work where a license is required. Ask to see a current certificate showing general liability and workers compensation coverage, and note the expiry dates. Then check the license details with the office that issued it.
The Federal Trade Commission guide on hiring a contractor, hosted on govinfo.gov, advises homeowners to check licensing, get written estimates from several firms, and ask for references. Erie County guidance, which reproduces Federal Trade Commission advice, likewise says to consider only licensed and insured contractors and check complaints before hiring.
Get the scope, materials, and timeline in writing
Ask what the written estimate includes line by line. It should name the siding material, profile, exposure, and color, state whether old siding is removed or covered, and describe work on trim, flashing, house wrap, and sheathing repair. Work on vents, lights, or outlets should be listed too.
Ask for a start window, a stage sequence, and conditions that could shift the schedule, such as weather or hidden damage after tear off. The Federal Trade Commission guide stresses getting promises in writing, so treat a verbal assurance as unfinished until it appears in the contract.
Clarify permits, access, and daily cleanup
Ask who applies for the permit, who schedules any required inspections, and where the permit will be posted on site. A regular local provider should name the office and the normal steps without hesitation.
Then settle practical points. Where will materials and a waste container sit. Which doors and paths will the crew use. How will plants and paving be protected. What cleanup happens each evening, and what final cleanup is included. Written answers here prevent most friction.
Ask who performs the work each day
Ask whether the firm uses its own crew, another crew, or a mix. Ask who leads on site, how you reach that person, and what hours the crew will work. If stages involve different teams, ask how each handoff is checked.
This is not a test of firm size. The point is accountability. Know before the start date who is responsible for daily progress, who can approve a small field decision, and who you call if a detail looks wrong.
Pin down how changes are approved
Hidden damage is the most common reason a scope changes. Rotten sheathing or failed flashing may only show after old boards come off. Ask in advance how such findings will be shown to you and how the schedule will be updated.
Agree on a simple rule and get it in the contract: no extra work starts until the change is described in writing, priced as a line, and signed by you. A clear process keeps the final account aligned with what you approved.
Check references in a useful way
Ask for recent jobs with a similar material and scope, not just a long list of names. When you call a reference, ask what was installed, whether the crew arrived as scheduled, how changes were handled, how cleanup went, and whether the owner would hire the same firm again. Short, specific answers tell you more than general praise.
You can also check complaint records through local consumer protection channels, as the Erie County guidance suggests when it advises homeowners to get recommendations and check for complaints. Look for patterns rather than a single dispute. You can see service coverage on the areas hub before you collect estimates.
Read warranty coverage for materials and workmanship
Ask two separate warranty questions. First, what does the material maker cover, for how long, and what conditions or upkeep steps are required to keep that coverage valid. Second, what does the firm itself cover for workmanship, for how long, and what is excluded.
Ask how a claim is filed for each warranty, who carries out the repair, and what records you should keep. Request copies of both warranty documents before the job ends, and file them with the contract. Keep asking until each term is clear in plain words.
Compare written estimates on equal terms
Collect written estimates from several firms for the same scope, as the Federal Trade Commission guide recommends. Line them up by material, tear off scope, flashing work, trim scope, cleanup, and warranty terms. A lower total on a thinner scope is not the same offer as a fuller scope.
Ask each firm to explain any line you do not follow. Note what drives cost in words: wall area and height, access, material choice, finish work, and disposal. Once scopes match, judge clarity, references, and schedule, not a single headline figure.
Frequently asked questions
Which license and insurance papers should I ask to see?
Ask for the full legal name of the firm, its license number where a license is required, and a current certificate that shows general liability and workers compensation coverage. Write the details down and check the license with the issuing office. If a firm cannot produce clear papers, pause and get another written estimate before you commit to any work.
Should I get the full scope in writing before work starts?
Yes. A useful written estimate names the siding product, profile, and color, lists tear off or cover work, and states what happens to trim, flashing, and house wrap. It also sets a start window, a work sequence, and a cleanup plan. If a detail matters to you, ask for it in the document rather than relying on a verbal note.
Who will do the work and who handles permits?
Ask who pulls the permit, who will be on site each day, and whether any part of the job goes to another crew. Get a contact name for daily questions and a plan for site access, parking, and material storage. Clear answers before the start date reduce delays and help you know who is responsible if a detail needs attention.
How are changes and warranty terms handled?
Ask how a change is priced, approved, and added to the schedule, and insist that each change is signed before extra work begins. For warranties, ask what the maker covers for the material and what the firm covers for workmanship, how long each term lasts, and how a claim is filed. Keep both warranty documents with the signed contract.
