Find a Premium Deck Builder | Seth's Home Pros
Most deck failures in Maine start at two spots nobody looks at: the ledger board bolted to the house, and the footings under it. Flash the ledger wrong and water runs behind it into your rim joist for years before a soft floor gives it away.
A deck here holds snow all winter, and drifting piles it deepest right where the deck meets the house. That is real structural weight, so framing and hardware have to be sized for it, and footings have to sit below the frost line or the whole thing lifts and settles twelve times a season.
The state sets no bar a deck builder has to clear before picking up a hammer, so our ten-step screening covers insurance, references, financial stability and work history instead. You get three builders quoting the same scope, and the introduction costs you nothing.
Almost every deck failure in this state comes down to two details most homeowners never look at. A good deck builder in Maine gets both right without being asked.
I match you with three who do.
The ledger and the footings
Decks don't usually fail because of the decking. They fail at the two connections nobody sees.
The ledger. That's the board bolting your deck to the house, and it carries an enormous share of the load. Two things go wrong with it. It gets fastened with the wrong hardware, or it gets installed without proper flashing.
The flashing is the one that matters most in Maine. An unflashed or badly flashed ledger lets water run behind the board and into the rim joist of your house. You won't see it. It happens for years. By the time there's a soft spot on the floor inside, you're not repairing a deck, you're repairing the structure of your home.
Deck collapses, when they happen, are almost always ledger failures. This is the single most important detail on the project and it costs almost nothing to do correctly.
The footings. Same frost problem as everything else here. Footings set above the frost line heave, and a heaving deck racks, opens gaps, pulls at the ledger, and eventually makes the stairs and railings unsafe.
Ask any deck builder quoting your job how he flashes a ledger and how deep his footings go. Both answers should be immediate and specific.
Who hires a deck builder in Maine
People replacing a deck that's twenty years old and starting to feel springy, and people adding outdoor living space to a house that never had it.
The replacement conversation is the more common one, and it's usually driven by soft boards. Worth knowing: if the decking is going, the framing underneath is the same age and deserves a real look before anyone just re-decks over it.
What a deck project includes
Footings, framing, ledger and flashing, decking, railings, stairs, and whatever you add on top: built-in seating, lighting, a pergola, a screened section, or a pad for a hot tub.
Material is the decision that drives the budget.
Pressure-treated is the cheapest, and it holds up fine if it's maintained. It also moves, checks, and needs re-sealing on a schedule most people don't keep.
Cedar looks better and weathers gracefully, at more money, and it still wants maintenance.
Composite and PVC cost the most up front and cost the least afterward. In a Maine climate, where a wood deck spends five months under snow and ice and gets sun-baked for three, that trade favors composite more than it does in a milder state.
Where in Maine my deck builders work
All 30 towns in the service area. Coastal exposure changes material and fastener selection meaningfully, so an oceanfront deck in Cape Elizabeth is specified differently from one in Skowhegan.
When to build a deck in Maine
Everyone calls in May. That's the problem.
Good deck builders here fill their season in late winter, so the homeowner who calls when the weather turns nice is competing for what's left. Call in February or March for a summer deck.
There's also a case for building in the fall. Crews have more availability, the weather is often better for working than July, and you're ready the moment spring arrives instead of waiting through it.
Footings need frost out of the ground, so ground work opens in April on the coast and May inland.
Why building a deck in Maine is different
Snow load and freeze-thaw.
A deck here carries snow all winter, and that load is real structural weight the framing has to be sized for. Add drifting where the deck meets the house and it concentrates in exactly the spot where the ledger already carries the most.
Freeze-thaw then works on every connection, every fastener, and every footing, twelve times a winter. Hardware that's adequate in a mild climate loosens here.
And the statewide fact: Maine does not license general contractors or builders, only plumbers and electricians. There's no deck builder license to check. Insurance, references, financial stability, and reputation are checkable, and that's what my 10-step process checks.
How to hire a deck builder without getting burned
- Ask how he flashes the ledger. If the answer is vague, keep looking. This is the question.
- Ask how deep the footings go and whether that's below frost for your town.
- Get three quotes. Deck quotes vary mostly on framing quality and material, and those are exactly what a low bid economizes on.
- Confirm the permit. Most Maine towns require one for a deck above a certain height or size, and an unpermitted deck is a problem when you sell.
- Get it in writing. Maine requires a written contract above $3,000 in labor and materials. The Maine Attorney General publishes a free model contract.
- Watch the deposit. Maine caps the initial down payment at one-third of the contract price.
How much a deck costs in Maine
Ranges from recent quotes across my network:
| Deck | Range | Timeline |
|---|---|---|
| Small pressure-treated, ground level (under 150 sq ft) | $10,000 – $22,000 | 1 – 2 weeks |
| Medium, cedar or composite (150–300 sq ft) | $22,000 – $48,000 | 2 – 4 weeks |
| Large composite with railings and stairs (300–500 sq ft) | $40,000 – $75,000 | 3 – 5 weeks |
| Raised, multi-level, or with pergola and screened section | $65,000 – $100,000+ | 4 – 7 weeks |
A GC's fee typically runs 10% to 20% of project cost.
Height drives cost more than square footage does. A raised deck needs bigger footings, more structure, and code-compliant railings and stairs, so a small deck ten feet off the ground can cost more than a large one at grade.

The 10-step vetting process
- Intake call: company, crew size, service area, project types, capacity, pricing posture.
- Financial stability check: years in business, structure, ability to carry materials and labor, supplier payment history.
- Insurance verification: general liability and workers' comp certificates pulled and stored.
- Reference checks: past homeowners, subs, and suppliers. Minimum three, not only the ones they pick.
- Reputation audit: Google, Facebook, BBB, local word of mouth, complaint and dispute search.
- Portfolio review: completed work, in person or in detailed photo and video.
- Communication test: speed of reply, clarity of writing, handling of a difficult question.
- Contractor agreement signed.
- 60-day probationary period: first projects watched closely, homeowner feedback gathered actively.
- Ongoing performance review: underperformers come out of the network.
What else do people ask about hiring a deck builder?
Do I need a permit for a deck in Maine? Usually, above a certain size or height. Thresholds vary by town, so check with your code office.
Composite or pressure-treated in Maine? Composite costs more up front and less over time. In a climate with five months of snow load and heavy freeze-thaw, that trade favors composite more than in milder states.
How long does a deck last in Maine? A well-built pressure-treated deck with maintenance, roughly 15 to 20 years. Composite decking lasts longer, but the framing underneath is still wood and ages on its own schedule.
Can I just replace the decking and keep the frame? Sometimes. Get the framing, ledger, and footings inspected first. Putting new decking on failing structure is money spent on the wrong thing.
Does Seth's Home Pros build decks? No. I'm not a contractor. I make the introduction and the contract is between you and the builder.
