Window Replacement, Siding & Sunrooms in Durham, NC
Over 40 years of local experience.
Durham mixes historic bungalows in Trinity Park and Old North Durham with newer homes near Southpoint and Hope Valley. Each era of home has its own window quirks, its own siding wear patterns, and its own ideas about outdoor living space.
At Harland Windows & Siding, we handle window replacement, siding installation, and custom sunrooms for homes throughout Durham. We've worked across the Triangle for over 40 years, and one call covers all three services.

Energy-Efficient Window Replacement
Do you feel a draft near your windows even when they're closed? Does the upstairs of your home stay hot long after the sun goes down? Those are signs your windows have stopped doing their job.
We replace old windows with custom-built Heat Mirror high-efficiency windows. Heat Mirror technology adds a suspended film between the panes of glass. That film blocks more heat than a second pane alone, so your home stays cooler in summer and holds warmth better in winter.
We handle whole-house replacements as well as single-window projects. Every window is custom built to fit your home's exact openings, including the non-standard sizes common in older Durham houses.
A 1940s bungalow in Trinity Park needs a different approach than a home built in the last decade near Southpoint. The old plaster walls and original trim around Trinity Park openings take more care to protect during removal. Newer homes near Southpoint usually have standard framing, so the work moves a bit faster. Either way, our crew lays down drop cloths and protects the work area before the first window comes out.
Homes built before 1978 need one extra step. Lead-safe work rules apply to those houses, and our crew holds a valid EPA certificate for that work. We confirm this before any project begins.
Not sure if your windows need replacing? Watch for these signs:
- Drafts or cold spots near closed windows.
- Foggy glass or moisture trapped between the panes.
- Windows that stick, jam, or won't stay open.
- Energy bills creeping up each season.
- Outside noise that feels louder than it should.
- Frames showing cracking, rot, or warping.

"The install on my older home was tricky, but the crew handled it beautifully. The price came in at about half what the big box stores quoted, and the warranty was better too."

Siding Installation & Replacement
Your siding is the first line of defense against rain, wind, and humidity. When it starts to crack, warp, or pull away from the wall, moisture gets in behind it. That causes real damage over time.
Does your siding have soft spots? Are there spots where paint peels no matter how many times you repaint? Those are signs the material itself is failing, not just the paint.
We remove your existing siding, inspect what's underneath, and install new material that fits your home and your budget. We don't cover up old problems. We fix them first.
Sunroom Construction & Conversions
Do you have a screen porch that fills with pollen in spring, mosquitoes in summer, and cold air in fall? That space could be useful all year with the right conversion.
We build and convert sunrooms using EzeBreeze vinyl panel systems by PGT Industries. The panels slide open and closed in seconds, so you get fresh air when you want it and full protection when the weather turns. Want something more permanent? We also build fully heated sunrooms with insulated walls and Heat Mirror windows.
"Great experience from start to finish. The crew was on time, friendly, and cleaned up after themselves every day."

Frequently Asked Questions
How long does window installation take in Durham?
A single window takes about 30 to 60 minutes to install. A full-home project of 10 to 15 windows usually wraps up in a few days, depending on the count and any custom sizes. We give you a start and finish date up front.
Do you need a permit for window installation in Durham?
A permit is not required for a same-size window swap in most cases. A permit is needed when the job changes the size of the opening. Homes built before 1978 require an EPA-certified crew for lead safety, which we hold.
What siding materials do you install?
We install a range of materials suited to the NC climate. During your estimate, we'll look at your home's current condition, your budget, and your preferences to recommend the right fit. We strip the old siding before installation and do not install over failing material.
Can you convert my screen porch into a sunroom?
Yes. Screen porch conversions are one of the most popular projects we do in the Triangle. We convert existing screen porches into EzeBreeze sunrooms or fully enclosed, heated sunrooms with insulated walls. The right option depends on how you plan to use the space.
