Connecticut oil tank contractors

Seven CT firms from public records — and the registration rule that matters: CT law requires residential tank contractors to be DCP-registered, with the number visible in their advertising.

Connecticut DEEP does not regulate residential heating oil tanks serving up to four dwelling units, but the state is not hands-off: contractors doing this work must register with the Department of Consumer Protection as Home Improvement Contractors, and state statute sets financial-assurance and training requirements for underground tank replacement contractors. If a firm's ads and trucks don't show a registration number, that's your first data point.

Verify before you hire

Look up any contractor's registration on the state's DCP eLicense lookup before signing. The regulatory background is on DEEP's official Residential Home Heating Oil Tanks — FAQs.

Entries below are compiled from public records and company websites as of August 2026. Remove The Tank has not vetted, endorsed, or partnered with these firms. Confirm current licensing with the state before hiring.

The Connecticut list is one step away

We keep a working list of Connecticut tank contractors compiled from public license records — names, towns, and what each one actually does. Tell us where to reach you and it opens right here, on this page.

Why we ask: a list of ten firms means ten phone calls where you retell your story and get ten quotes with different scopes. Give us permission and a person here reads it and replies within one business day. You still get the full list either way.

Don't want to share anything? The official Connecticut registry linked above is public and searchable on its own — we'd rather tell you that than pretend this list is the only way.

Firms appear in no ranked order. This is what we could verify from public sources in August 2026, not a census of the CT market.

Or let us do the legwork

Connecticut underground removals run $1,500–$3,800 (2025–2026 market ranges; spot-check against current local quotes before relying on them). The contractor contact form takes your details once and matches you with licensed CT contractors — independent of this directory.
