Replacing windows in Kennebunk is really two questions: the window itself, and what happens to the trim around it. The casing, the stool, the apron and the back band all come out of the wall differently depending on how the old sash is removed, and that is the part you look at every day afterwards.
Which answer is right depends on your address. Behind the Federal and Greek Revival facades on Summer Street sits interior woodwork that cannot be bought back at any sensible price, while the shingle-style cottages toward Gooch's Beach usually carry plain, much-painted trim where straight replacement makes sense. Ask Town of Kennebunk code enforcement what rules actually apply to your parcel.
We introduce you to three contractors from our network who quote the same scope, so you can compare how each one plans to handle your interior. The introduction costs you nothing, and every contractor clears a ten-step screening on insurance, references and work history first.

Where in Kennebunk is your house?
Kennebunk sets a high bar for interiors. And the standard differs between the two halves of town.
Summer Street is one of the finest Federal-era streetscapes in New England, and the interiors behind those facades are the reason. Trim of that age and quality is not replaceable at any sensible price, which changes the whole calculation on how windows come out.
Whether your address carries an actual regulatory review or a recognition that is honorary is genuinely different from property to property, and the answer changes what you may do outside. Ask Town of Kennebunk code enforcement about your parcel specifically rather than assuming either reading.
Toward the beaches the vocabulary changes. Shingle-style summer cottages with simpler, plainer interior trim, often painted many times and rarely precious. Replacement there is a straightforward decision and the salvage argument carries much less weight.
A steady share of the work here is winterising a seasonal property, and windows are usually the largest line in that. Worth asking whether the interior detailing that suited a summer house still suits one lived in through the winter.
Salt and wind reach both halves of town, which is a hardware and finish question to raise with whoever quotes.

Plan on 10% to 20% of the project cost for the general contractor’s fee.
Kennebunk falls in the upper half of every row. On Summer Street, it clears them.
Much of that cost comes from interior work rather than the unit price.
Homeowners are rarely told this part. Trim work is labour.
Its cost follows the number of openings and the profile’s complexity, not the glass size. Twenty small windows with elaborate casing require far more interior work than eight large, plain windows, even though the second house contains more glass.
Ask for trim as a separate line item so it doesn’t become a surprise in week three.

What does a new window do to the room?
Look at one window from inside. The surrounding pieces face different risks.
Learn the four names and you can have this conversation properly. The casing is the flat trim around the opening. The stool is the shelf across the bottom, the part most people call the sill. The apron is the piece under the stool. A back band is the moulded edge some casings carry.
On very old houses there may be none of that. A plastered return runs the wall surface straight into the window with no wooden trim at all. That cannot be taken apart and put back, and replicating it is plasterwork rather than carpentry. If you have them, say so before anybody quotes.
How much of this survives depends on how the window comes out, which is the one place this page touches a decision made elsewhere. A job that leaves the existing frame usually leaves your trim alone. A job that goes back to the rough opening usually does not. Your contractor should tell you which he is quoting and what it means inside.
Salvage is a line item, not a favour. Original casing can often be eased off, labelled and put back if somebody is paid to work slowly and accept that a few pieces will split. Priced as an hour, it will not happen. Priced as a day, it usually does.
Matching new trim is harder than it looks. Profile, species, and a paint history going back generations. New casing in one room reads as new against the original casing visible through the doorway, and nobody notices it in the shop and everybody notices it at home.
The stool is the piece that catches people out. If the new unit sits at a different depth in the wall, the stool no longer projects the way it did, and the proportion of the whole assembly changes. It is subtle and it is the thing that makes a restored room look slightly wrong without anybody being able to say why.
And paint is the compliance question. On a house built before 1978 every one of these surfaces is painted, and disturbing them brings in federally required lead-safe work practices. Ask to see the certification.
Walk the house with each contractor, one room at a time, and put the trim work in the quote. On a good house, that sentence matters more than the price difference between two window brands.
We’d choose the better trim plan.

This applies to owners of Federal or Greek Revival houses with irreplaceable interior trim. It also applies to people unhappy with work done in one room, along with cottage owners near the beaches planning a plain, sensible replacement.
The scope covers removal and repairs to the sill or framing. It also covers the units, flashing, air sealing, plus the interior work.
That includes saving or replicating the casing and stool, followed by the apron, back band, and plaster repairs.
On a house of this age, put the trim scope in writing. Before anything is ordered, agree room by room which pieces will be saved or replicated.
Mark the new pieces too.
Schedule the openings for warm weather. Sealants and tapes have working temperature ranges, and the wall remains open during the work.
The interior work isn’t bound by that limit. Trim salvage and replication can continue into autumn, as can painting after the units are installed.
Separating the two schedules often gets you a better crew for each phase.
Because the inside is the point in houses this good. In most towns, the interior trim around one window is a finish detail that nobody considers.
Here, it is often older than the state and worth more than the window filling the opening.
Worth knowing while you compare quotes: Maine does not license general contractors or builders. Plumbers and electricians hold state licenses and no one else does, so no amount of joinery skill comes with a credential attached. Insurance, references, financial stability and reputation are checkable, and our ten-step process works through all four before you get a name.
What do people in Kennebunk ask before starting?
What happens to my interior trim during a window replacement?
It depends on how the window comes out. Leaving the existing frame usually saves it. Going back to the rough opening usually does not.
What is the stool on a window?
The shelf across the bottom, the piece most people call the sill. Its projection changes if the new unit sits at a different depth in the wall.
Can original casing be reused?
Often, if somebody is paid to work slowly and a few pieces are accepted as losses. Priced as an hour it will not happen.
What about a plastered return with no trim?
It cannot be dismantled and put back. Replicating it is plasterwork, so flag it before anybody quotes.

Tell us the house’s age and whether each window has wooden casing or a plastered return. That determines how careful the work must be.
