# Hiring a Window, Siding and Gutter Contractor in Maine: Lead-Safe Scraping, Window Contracts and Shoreland Limits

> A typical Maine window, siding or gutter job runs about $3,600 to $9,900. Maine licenses no exterior contractor, but window replacements are named in the Home Construction Contracts Act, so a job over $3,000 needs a signed written contract. On a pre-1978 house, ask how the crew will contain paint dust, and near water check the town's shoreland rules before adding on.

## Key facts

- **State license:** None for window, siding or gutter contractors
- **Older houses:** Lead-safe practices required when disturbing paint on pre-1978 homes
- **Typical job:** About $3,600 to $9,900 (Maine calculator default)

The outside of a Maine house takes the weather head on. Salt wind on the coast at Kittery and Rockport, snow load and ice inland at Gray and Lisbon, and long freeze-thaw seasons at Mars Hill all work on clapboards, trim, window sashes and gutters. When the paint fails or the windows rattle, Maine homeowners tend to call one company to handle the whole envelope. That makes the contract, and the crew's handling of old paint, the two things worth getting right.

## Are replacement windows covered by Maine's contract law?

They are named in it. Maine's Home Construction Contracts Act defines home construction as building, remodeling or repairing a residence of up to three units, and the definition expressly lists window replacements, along with electrical, plumbing and heating work and carpeting ([10 M.R.S. §1486](https://legislature.maine.gov/statutes/10/title10sec1486.html)). Siding and gutter work on a house falls under the same Act as repair or remodeling.

Once the price crosses $3,000, the agreement has to be on paper and signed by both of you, with a copy in each pair of hands before the crew starts ([§1487](https://legislature.maine.gov/statutes/10/title10sec1487.html)). The law also holds the opening payment to no more than a third of the total. Window orders are custom, and a company may want money to place them; a third of an $8,000 window job is about $2,670, which on most jobs comfortably covers the order deposit.

For windows, insist that the contract lists the manufacturer, the product line, and each opening by size and style. "Twelve vinyl replacement windows" is not a description you can enforce. Ask whether the price includes new interior and exterior trim, how they'll handle rot found in the sill, and who disposes of the old sashes.

No state license covers this work. The [Attorney General's page](https://www.maine.gov/ag/consumer-protection/consumer-help-topics/housing/home-construction-and-repair) is clear that contractors and trades such as roofing and framing aren't licensed or regulated in Maine, so the contract and the company's insurance certificate are the protection you have.

## How should a crew take old paint or siding off a pre-1978 house?

Carefully. By the state environmental agency's estimate, lead paint may be present in over half the houses in Maine; it rates pre-1950 houses as the riskiest, and flags renovation work on anything older than 1978 ([Maine DEP lead](https://www.maine.gov/dep/waste/lead/)). Exterior work on an older house in South Berwick, Winslow or Old Town disturbs exactly the surfaces most likely to carry it: clapboards, window sashes, trim and porch rails.

On a pre-1978 home, federal renovation rules require lead-safe work practices, and Maine has its own lead statute and DEP rules on top. In plain terms, ask the contractor:

- How will you contain paint chips? Ground sheeting that extends well past the work area is the minimum.
- Will you power-wash, dry-scrape or use heat? Some methods throw far more dust than others.
- How will you protect a vegetable garden, a sandbox or a well head near the wall?
- What happens to the debris at the end of each day?

If you don't know whether there is lead, DEP's [find a lead professional](https://www.maine.gov/dep/waste/lead/findalp.html) page lists licensed inspectors who can test before work starts. Covering old clapboards with vinyl leaves the lead in place, which is legal, but any later work on those boards meets the same paint.

## Can you add a porch or a bump-out near the water?

On a lake or coastal lot, check before you design. State law draws the shoreland line 250 feet back from the normal high-water mark of great ponds, rivers and salt water, and 75 feet back from some streams ([38 M.R.S. §435](https://legislature.maine.gov/statutes/38/title38sec435.html)). Inside that line, your town's own shoreland ordinance governs, and DEP points homeowners to the town code officer as the place to start ([DEP shoreland zoning](https://www.maine.gov/dep/land/slz/)).

A new porch, an enclosed sunroom, or larger windows that come with a wall bump-out can count as expanding the structure. Replacing siding and windows within the existing footprint is typically a different matter. The safe practice is to describe the full plan to the code officer and get the answer in writing before you sign a contract that assumes it.

## Will new windows stop the ice on the eaves?

Not on their own. Efficiency Maine treats ice dams as a symptom of attic air leaks rather than of the windows or gutters ([Efficiency Maine air sealing](https://www.efficiencymaine.com/at-home/air-sealing/)). A gutter contractor in Bucksport or Westbrook who tells you heavy-gauge gutters will solve ice problems on a leaky attic is selling the wrong fix. Gutters can be torn off by an ice ridge regardless of their quality.

What gutters do well is move rain away from the foundation. Ask where each downspout will discharge, and keep the water well away from a fieldstone or block cellar wall.

## What does a Maine exterior job cost?

The Maine calculator default for a typical window, siding or gutter job is about **$3,600 to $9,900**; the [Maine exterior cost estimate](/s/greater-portland--me/exterior-contractors/cost) explains what it covers. Staging on a tall Victorian, lead-safe prep, rot repair and custom trim work all push a project higher. A single-story ranch with straightforward siding sits near the bottom.

Exterior crews work the warm months. Paint needs dry weather and moderate temperatures, and the season is shorter the farther north you go. If you live in Aroostook or the western mountains, book in winter for a summer slot, and put the estimated start and completion dates the Act requires into the contract.

## Who carries the risk if a ladder slips or a storm hits mid-job?

An exterior job leaves the house open in a way an interior one doesn't. Siding comes off a wall and housewrap is exposed for days; a window opening may be covered with plastic overnight. Ask how the company protects an open wall from a sudden rain or wind, and who pays for interior damage if the protection fails. That answer belongs in the contract, not in a handshake.

Ask too what happens to the schedule if an early snow ends the season with one side of the house unfinished. A sensible contract says the crew will close the house up weathertight before stopping, and names the payment that is held back until the rest is done in spring. Without that, you can spend a winter with a half-sided house and most of the money already paid.

## How do you compare two quotes for the same house?

Make sure they describe the same job. Line up:

- the product for each window and the siding line, by name
- whether old siding comes off or new goes over it
- trim and corner details, including how the windows are flashed
- rot repair, priced per foot or per board
- lead-safe prep, described in words, not as a checkbox
- cleanup, disposal and magnetic sweeping for nails

Then ask each company for a certificate of insurance made out to you. On an exterior job, falls from ladders and staging are the main risk, and the homeowner shouldn't be the one carrying it.

## FAQ

### Do window, siding & gutter contractors in Maine need a license?

Maine does not license or register general contractors; the Home Construction Contracts Act (10 MRS 1487) requires a written contract, signed by both sides, for any home-construction or repair job over $3,000, and limits the down payment to one-third of the contract price.

### How much does siding or window work cost in Maine?

Maine's calculator default for a typical window, siding or gutter job is about $3,600 to $9,900. Re-siding a whole two-story house, or replacing every window in it, will run well above that figure.

### Do window replacements need a written contract in Maine?

Yes, when the price is over $3,000. Maine's Home Construction Contracts Act names window replacements in its definition of home construction, so the contract must be in writing, signed by both sides, and limit the first payment to a third.

### Do I need lead-safe practices to scrape old paint?

On a home built before 1978, federal renovation rules require lead-safe work practices whenever painted surfaces are disturbed. Maine DEP says more than half of Maine homes may have lead paint, so assume it until a test says otherwise.

### Can I build or expand near the lake?

Land within 250 feet of a great pond, river or tidal water is in the shoreland zone, where every town enforces its own ordinance. Expanding a porch or deck there usually needs approval from the code enforcement officer first.
