How we rank plumbers 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 plumbers 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.

Local conditions

Hiring plumbers in Wilmington: what the local data says

  • 71% of homes in Wilmington were built before 1970 and the median home dates to 1945. Homes of that age often still have galvanized steel or cast iron lines, so ask whether a plumber has worked on them before quoting a repair.
  • The typical last spring frost in Wilmington is around March 31 and the first fall frost around November 18, roughly 232 frost-free days. With about 74 nights at or below freezing a year, outdoor spigots and pipes in unheated spaces are worth winterizing before the first frost.
  • Wilmington gets about 52 inches of precipitation a year and about 17 inches of snow, and August is typically the wettest month. Sump pumps and basement drains get their real test in the wettest weeks, so have a pump checked before then rather than after the first wet basement.

Common questions

Plumbers in Wilmington: quick answers

How are the plumbers 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 plumbers 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 plumber in Wilmington?

Use this list to shortlist two or three plumbers, 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 plumber's license in Delaware?

Licensing in Delaware runs through the Delaware Department of Labor, which registers contractors, and the Division of Professional Regulation, which licenses plumbers, electricians and HVAC technicians. Before hiring anyone in Wilmington, check a general contractor in the Department of Labor contractor registry (contractorregistry.delaware.gov), and a plumber, electrician or HVAC technician in the DELPROS license portal (delpros.delaware.gov). Contractors also carry a Delaware business license. Also confirm current liability insurance, and get the license number in writing on the estimate.

Which plumbers serve Wilmington?

This page lists Benjamin Franklin Plumbing, Roto-Rooter Plumbing & Water Cleanup, Horizon, Dr. Pipes Plumbing, FH Furr and Dickson Plumbing, in ranked order. All of them publish a phone number, so you can call directly.

When is the best time to book plumbers in Wilmington?

Going by Wilmington's own weather records (typical last spring frost around March 31, first fall frost around November 18), the usual windows are late winter, before about March 31 or early fall, before the first frost around November 18. Booking a few weeks ahead of those windows beats the rush.

What to look for when hiring a plumber in Wilmington

  • Ask for the Delaware Master Plumber license. In Delaware, plumbers need it from the Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners. Verify it at the official Delaware license lookup before signing. Unlicensed workers may do plumbing only under a Master Plumber who employs them, so ask for the company's Master Plumber license number.
  • Written estimates. Any plumber 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 plumber who's done work in Trolley Square or Riverfront will understand local housing stock better than a regional chain.
