★★★★★5/5insert or full-frame, chosen window by window
Most Wellesley window projects are insert replacements, where the new window fits inside the existing frame and the interior trim stays in place. If the frames are rotted, out of square or you want a larger glass area, a full-frame replacement is the better choice. We check every opening during a free estimate, tell you which method each window needs and give you a written quote. Most whole-house projects take only a few working days once the windows arrive.

replacement windows we install in wellesley

Insert replacement windows
The fastest and least disruptive option. The old sashes come out, the frame is checked and sealed, and the new unit is set, insulated and trimmed. Interior casing and plaster are left alone, which matters in older Wellesley homes.

Full-frame replacement
The whole window comes out down to the rough opening. We inspect the framing, repair any rot, install new flashing tied into the siding's weather barrier and set a complete new unit. It is the right choice when frames are damaged or when windows are replaced during a siding project.

New-construction windows
For additions and major remodels, we install nail-fin windows and coordinate with the other trades on site so the windows never hold up the job.
styles and materials
Double-hung windows are the classic choice for Wellesley colonials and capes. We also install casement, bay and bow windows, and we can match the grille pattern of your original windows so the front of the house keeps its character.
- Vinyl: durable, low maintenance and the most budget-friendly option, in a wide range of colors
- Wood: the traditional look for older homes, built to order with custom colors and profiles
- Composite and fiberglass: strong, stable through temperature swings and finished in colors that hold up
We are an Andersen certified contractor and also install Harvey windows, and we can supply Pella and Marvin windows on request. Harvey windows carry a lifetime warranty on materials and labor plus accidental glass breakage coverage. Andersen windows come with manufacturer coverage on glass and components, and we add our own labor warranty on top. We review the exact warranty for your windows before installation.

windows for older wellesley homes
Many Wellesley homes, from the early colonials near Wellesley Hills to the Victorians around Wellesley Farms, still have original or decades-old windows in openings that are no longer square. Replacing them well takes careful measuring and trim work. On a recent project in Wellesley, our crew replaced 26 windows and the entry door, measuring every opening individually so each unit sat square in the existing frame.
Homes built before 1978 may have lead paint on the old window trim, so replacement must follow lead-safe work practices. Plum ProExteriors holds a Lead-Safe Renovation Contractor certificate (license LR004195), so every pre-1978 home is handled with the required containment and cleanup. If your home is in a historic district or under design review, we help you choose windows with the right profiles and grille patterns and build the review step into the schedule. See our historic home remodeling page for more.

frequently asked questions
How much does window replacement cost in Wellesley?
Every job is quoted after an on-site inspection, because size, style, material and installation method all change the price. Our online cost calculator gives a quick range for windows, and the estimate visit is free.
Do I need a permit to replace windows in Massachusetts?
Often yes, especially for full-frame work or any change to the opening. Requirements vary by town, and we handle the permit for Wellesley projects.
Should I replace all my windows at once?
Not necessarily. Many homeowners start with the largest or least efficient windows and finish the rest later. Doing them together usually saves on setup and keeps the look consistent, so we will quote it both ways if you ask.
Can windows be replaced in winter?
Yes. We replace one opening at a time, so each room is only open briefly, and installation continues through the cold months.
Are there rebates for new windows in Massachusetts?
In some cases. Eligibility for Mass Save and similar programs depends on the windows and the program criteria at the time. We can walk you through what applies during the estimate.
