Treat these as planning numbers, then get three itemized bids against the same scope. Quotes for an identical pool can land 20% apart in one city; compare decking, barrier fencing, electrical runs, drainage, permits, and yard repair before comparing the bottom line.
The inground pool cost guide covers common line items, and the pool loan calculator shows what the financed portion does to the monthly payment.
Discuss these Maine conditions before a builder finalizes the price and schedule:
Bring a few reference photos and a rough must-have list to each site visit so builders quote the same target. Browse pool design ideas and pool shapes; to search farther out, use the Maine pool builders guide or the nationwide finder.
Ask for decking, drainage, shade, lighting, and outdoor-kitchen work as separate options while access is still open.

Maine's pool market concentrates around Portland, southern coastal towns, and the New Hampshire border. The builder bench and outdoor construction season are both short, so permits and scheduling should start well before spring. For statewide rankings, city counts, and Maine pricing, see the Maine pool builders directory.
Ask about experience with Portland soil, access, drainage, and permit offices, then check completed projects in the pool type you want: gunite, fiberglass, or vinyl liner. Confirm current licensing where required and insurance with the issuing source. The contract should spell out materials, allowances, exclusions, timeline, change-order pricing, payment milestones, and warranty responsibility. Compare at least three itemized bids against the same scope.
Most inground pool projects in Portland, ME run $52,000 to $161,000+ installed, with typical projects landing around $83,000. By build type: vinyl liner $46k–$75k, fiberglass $57k–$103k, and gunite/concrete $71k–$144k. Rocky soils and ledge are routine — put excavation language in writing — and rural lots add access logistics. Frost-depth plumbing, freeze-tolerant decks, and covers rated for snow load are simply how pools are built this far north. Request itemized quotes from at least three builders to price your site and scope.
Most inground pool projects in Portland take 8–16 weeks from permit approval to completion. Weather, inspections, material availability, access, and design complexity can extend the schedule. Ask each bidder to separate permit lead time from construction time and identify the milestones that control payments.
Use the customer rating and review count to narrow the 14 builders listed here, then inspect recent projects and reviews. Confirm current licensing where required, insurance, permit responsibility, warranties, and payment milestones. Give at least three builders the same project brief so their itemized quotes are comparable.
Yes — Portland and most municipalities in Maine require building permits for swimming pool construction, covering structural, electrical, and plumbing inspections plus barrier/fencing requirements. Most builders listed here handle the permitting process as part of the project — confirm it in writing, along with who schedules each inspection.
The outdoor season in Portland runs mid-June through early September — about 3 months unheated, and most owners add a heater to stretch both shoulders. A full professional winterization each fall protects plumbing and equipment through the freeze. The unheated season runs from mid-June to early September, and a heat pump can extend it. Winters are long and freezing statewide, so inground pools need a full close.
Mowry Brothers Pools has the highest customer rating in this Portland list at 5 stars across 11 reviews. Northern Pool & Spa has the largest review count (195 reviews at 4.8 stars). The directory order uses rating and review count together, so the highest star average is not always the number-one result.
Maine has no general statewide contractor license, so due diligence is yours: insurance certificates, references, and recent local builds. Pool permits and residential-code barrier requirements (fencing, self-latching gates) run through your town's code enforcement office; shoreland zoning can add review near water.
Rocky soils and ledge are routine — put excavation language in writing — and rural lots add access logistics. Frost-depth plumbing, freeze-tolerant decks, and covers rated for snow load are simply how pools are built this far north. Vinyl liner leads, fiberglass grows every year for install speed, and heat pumps are near-universal on new builds. Simple, durable designs with automatic covers fit the climate and the character.
