Window Replacement, Siding & Sunrooms in Forest Hills, Sanford NC
Over 40 years of local experience.
Forest Hills is an established neighborhood in Sanford along the northern side of the city, developed primarily through the 1960s, 1970s, and 1980s. The area has mature tree cover and single-family homes on standard suburban lots, with ranch-style construction that is typical of Lee County development from that period. The neighborhood sits within a reasonable distance of the US-1 corridor and downtown Sanford, giving it a central location with a quieter residential character.
We serve Forest Hills homeowners with custom window replacement, siding installation, and sunroom construction. Harland Windows & Siding has worked throughout Lee County for over 40 years.

Energy-Efficient Window Replacement
Ranch homes in Forest Hills from the 1960s and 1970s were built with single-pane aluminum windows in most cases. Those windows lost most of their insulating value the day they were installed. Homes from the 1980s may have early double-pane replacements that have been through 35 or more years of temperature cycling. Seal failures in double-pane windows often show up as fogging or condensation between the panes. Are there rooms in your home that stay drafty in winter or overheat in summer?
We install custom Heat Mirror high-efficiency windows manufactured to your exact opening dimensions. The suspended film technology blocks radiant heat better than standard double-pane glass, which matters in a neighborhood with significant mature tree coverage that can limit airflow.
A homeowner in Forest Hills, Christy F., noticed condensation collecting on the inside of the glass every cold morning. After we installed Heat Mirror windows, the condensation problem disappeared once the new windows were in.
Homes in Forest Hills vary in age, and so does the condition of the windows in them. Homes in Scattered Oaks tend to be a different age, so the windows there may be at a different point in their lifespan. Either way, an in-home look tells us exactly where things stand.
Not sure if your windows need replacing? Watch for these signs:
- Windows feel cold to the touch in winter, even when closed.
- You see fog or moisture trapped between the panes.
- Windows are hard to open, close, or lock.
- You can hear outside noise clearly through closed windows.
- Your energy bills have crept up without a clear reason.
- Frames show cracking, rot, or warping.
"Worked directly with the owner, courteous and attentive. Top-quality work, with post-install follow-up."

Siding Installation & Replacement
Mature tree canopy in Forest Hills creates persistent shade on north and east elevations, keeping those walls damp longer after rain. Aluminum siding from the 1960s and 1970s dents, chalks, and loses its finish long before the substrate fails. Vinyl from the 1980s has been through enough freeze-thaw cycles to become brittle. We assess each home's specific condition during the estimate.
We strip old siding, inspect the sheathing and framing for damage, repair what we find, and install new material from a clean base.
Not sure if your siding needs replacing? Watch for these signs:
- Siding shows visible cracking or buckling along the seams.
- Caulk lines have separated around windows and corners.
- Soft or spongy spots appear near the bottom of the wall.
- Color looks faded or chalky compared to when it was installed.
- Moisture or staining shows up on interior walls near exterior corners.
- Panels rattle or feel loose in the wind.
Sunroom Construction & Conversions
Ranch homes in Forest Hills often have covered back porches that sit unused for half the year because of heat, cold, or insects. Converting that space to a three-season room or fully enclosed sunroom turns it into livable square footage. The mature trees in the neighborhood provide natural shade that makes a sunroom even more comfortable in summer.
We build EzeBreeze sunrooms using PGT Industries' sliding vinyl panel system for three-season use. For year-round comfort, we build fully enclosed sunrooms with insulated walls and Heat Mirror glass.
"The salesman followed through the entire installation, and any install issues were fixed promptly. Very pleased."

Frequently Asked Questions
How long does a full window replacement take in a Forest Hills ranch home?
Most ranch homes in this neighborhood can have all windows replaced in one to two days. The timeline depends on the number of openings and whether any framing repairs are needed. We give you a specific estimate when we measure.
Do you offer free estimates in Forest Hills?
Yes. We come to your home, take measurements, and give you a written estimate at no cost. Call (919) 851-0060 or request online to schedule a visit.
What kind of warranty comes with new windows, siding, or a sunroom?
Our windows carry a manufacturer's warranty that covers the glass, seals, and hardware against defects. Installation labor is also covered, so if something is not right because of how a unit was put in, we come back and fix it. We go over the exact terms for your project during your free estimate.
Do you offer financing for window, siding, or sunroom projects?
Yes. We offer financing options for homeowners who want to spread out the cost of a project. Monthly payment plans can make a whole-house window replacement or a new sunroom easier to fit into your budget. Ask about current financing options and rates when you schedule your free estimate.
