Window Replacement, Siding & Sunrooms in Cary, NC
Over 40 years of local experience.
Cary homes range from 1980s neighborhoods near downtown to newer construction out by Fenton. Each one faces the same hot, humid summers and the occasional ice storm in winter. That mix of age and weather means windows, siding, and porches all wear differently from house to house.
At Harland Windows & Siding, we handle window replacement, siding installation, and custom sunrooms for homes throughout Cary. We've worked across the Triangle for over 40 years, and one call covers all three services.

Energy-Efficient Window Replacement
Is your AC running nonstop in the summer? Do you feel a draft near your windows even when they're closed? Those are signs your windows are letting heat in and cool air out.
We replace old, inefficient windows with custom-built Heat Mirror high-efficiency windows. These are not the standard double-pane windows sold at hardware stores. Heat Mirror technology adds a suspended film between the panes, which blocks more heat in summer and holds more warmth in winter.
Whole-house replacements give you the biggest jump in comfort and the biggest drop in energy costs. We measure and build each window to fit your home exactly, so nothing gets shimmed or forced into place.
Preston and MacGregor Downs were built mostly in the 1980s and 1990s, so many of those homes still have their original windows. A whole-house job in one of those neighborhoods often runs toward the higher end of our price range, simply because the houses are larger and have more windows. Amberly and other newer Cary communities have windows with plenty of life left, so a homeowner there is more likely to need just a window or two replaced. Where does your home fall on that timeline?
Watch for these signs that it may be time to replace your windows:
- Your windows feel cold to the touch in winter, even when they're closed.
- You see condensation or fog building up between the glass panes.
- Windows are hard to open, close, or lock.
- You can hear traffic or lawn equipment clearly through closed windows.
- Your energy bills have crept up and you can't explain why.
- Frames show cracking, rot, or warping.
Most window replacement projects in Cary run between $6,000 and $40,000, depending on the number of windows, the style, and the glass package you choose. We provide free, written estimates so you know what to expect before any work begins.

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. That causes real damage over time.
Does your siding have soft spots near the base of the wall? Are there areas 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 near Fred G. Bond Metro Park or Koka Booth Amphitheatre that fills with pollen in spring, mosquitoes in summer, and cold air in fall? That space could work for you year-round 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.

Frequently Asked Questions
How much does window replacement cost in Cary, NC?
Most window replacement projects in Cary run between $6,000 and $40,000. The final number depends on how many windows you replace, their size and style, and the glass package you choose. We give free, written estimates with clear pricing.
Is a pocket install or full-frame install cheaper?
A pocket install is cheaper because the existing frame stays and we replace only the moving parts and glass. A full-frame install costs more since we remove the window down to the rough opening. We check the condition of each frame during your free measure.
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.
