Window Replacement & Exterior Trim on the South Shore
Replacement and new-construction windows with custom PVC and wood trim — flashed, sealed, and finished so water stays out and the exterior looks sharp.
What windows & trim covers — and who it's for.
This is window installation paired with the trim that frames and seals it — replacement or new-construction windows, plus custom PVC and wood trim, flashing, and weatherproofing. It's for homeowners with drafty, dated, or leaking windows, and anyone re-siding or remodeling who wants the openings done right.
Window & trim services we offer.
Replacement windows
New windows fit into existing openings with minimal disruption to the wall.
New-construction windows
Windows set during re-siding, additions, and rebuilt openings.
Custom PVC & wood trim
Trim packages around windows, doors, and the full exterior, built to fit.
Flashing & weatherproofing
Proper flashing and sealing so water is directed out, not behind the trim.
Why homeowners pick us for windows & trim.
A window is only as good as its installation. We flash and seal every opening so wind and water stay out, then finish it with trim that fits cleanly and lasts — the details that separate a window that performs from one that just looks new for a year.
We've handled custom trim work, window integration, and weatherproofing on homes of every age across the South Shore for over 30 years.
Installed right
Flashed and sealed openings, not just a window dropped in.
Custom trim
PVC and wood trim built to fit your home, not forced to generic sizes.
Low maintenance
PVC options that won't rot or need repainting in our coastal climate.
How a window & trim job goes.
We measure carefully, protect the interior, and finish each opening before moving on, so your home stays weather-tight throughout.
1. Measure & prep
We measure each opening, check its condition, and order the right windows and trim.
2. Set & flash
Windows are set level, flashed, and sealed against air and water intrusion.
3. Trim & finish
Custom trim goes on, gaps are sealed, and we clean up and review the work with you.

What customers say about our work.
We had all of the exterior trim around our house replaced, and I couldn't be happier with the work Chris did. The quality and attention to detail really stood out, and it was clear from day one that he genuinely cared about doing the job right — making sure the end result was something he'd be proud of, as if it were his own house. Beyond the great craftsmanship, I truly enjoyed working with Chris along the way. He was easy to talk to, communicative throughout the project, and clearly invested in the outcome. We loved the finished product so much that we've already scheduled him for more work, and I wouldn't hesitate to recommend him to anyone looking for a contractor who truly cares about both the process and the result.
Kyle Jennings South Shore, MAI've used CB Builders many times, for many projects. They're excellent at roofing and siding. Every time, they walk me through the specific challenges of the project and offer solutions to all of them. When I bring them onto a project, I'm confident the job will be done right. Will definitely use them again.
Dominic Watkins South Shore, MAWhether you need a roofer, new siding on your house, new windows, or even a deck — no need to look any further. They are very affordable, reliable, and very informative. I give them 5 stars and would recommend them to everyone.

Window & trim questions, answered.
How much do replacement windows cost?
Window pricing depends mostly on how many windows, the brand and style, and whether the openings need any repair. We price per project after seeing the openings, and the estimate is always free.
What's the difference between replacement and new-construction windows?
Replacement windows fit into existing openings with minimal disruption to the surrounding wall. New-construction windows are used when we're re-siding, building an addition, or the opening needs to be rebuilt. We'll recommend the right type for your project.
Do you install the trim too?
Yes. We build and install custom PVC and wood trim around windows, doors, and the whole exterior, with the flashing and sealing done so water can't get behind it.
Why does PVC trim cost more than wood?
PVC won't rot, hold moisture, or need repainting the way wood can, so it's a popular low-maintenance choice in our coastal climate. We install both and will explain the trade-offs.
Can new windows really make a difference?
Properly installed, flashed, and trimmed windows cut drafts and water intrusion and sharpen the look of the whole house. Installation quality matters as much as the window itself.
