How we rank deck builders in Wilmington

Each business is scored on signals we can verify from public data: a live, secure (HTTPS) website, mobile-friendliness, a published phone number and website, and fit with the deck builders category. We do not collect or display customer reviews, and we do not accept payment for placement. Businesses can claim their listing to correct contact details, but the rank is fixed by the data. Owners can claim a listing for a Verified badge and a direct link; sponsors appear only in labeled blocks outside the numbered list. Neither changes rank.

Common questions

Deck Builders in Wilmington: quick answers

How are the deck builders in Wilmington ranked?

Each listing is scored on public signals we can check ourselves: whether the website is live and secure (HTTPS), whether it works on a phone, whether a phone number and website are published, and how closely the business matches the deck builders category. We do not collect customer reviews, so no star ratings or review counts appear here, and no business pays for placement.

How do I pick the best deck builder in Wilmington?

Use this list to shortlist two or three deck builders, then read their Google reviews yourself, confirm license and insurance, and get written estimates before committing. The score here is a filter, not a verdict.

How do I verify a deck builder's license in Delaware?

Licensing in Delaware runs through the Delaware Division of Professional Regulation. Before hiring anyone in Wilmington, search the state's DELPROS license portal (delpros.delaware.gov) for the individual or company name, and ask for the license number up front. Contractors also carry a Delaware business license. Also confirm current liability insurance, and get the license number in writing on the estimate.

What to look for when hiring a deck builder in Wilmington

  • Verified license and insurance. Licensing requirements vary by state and county in Delaware, so ask for the license number and proof of insurance before any work begins.
  • Written estimates. Any deck builder who won't put the scope in writing is a red flag.
  • Review quality, not just volume. Read the 3-star reviews, they're usually the most honest.
  • Local references. A deck builder who's done work in Trolley Square or Riverfront will understand local housing stock better than a regional chain.
