Replacing windows in Kensington usually runs between $900 and $2,800 per opening depending on size, frame condition, and glazing. For the full-height glass walls and sliding doors common to the hillside homes here, whole-project pricing typically lands between $14,000 and $42,000. We give every Kensington homeowner a written price before any work starts, so you know the number before you decide anything. Call (252) 675-6980 to schedule a free estimate, and we’ll walk the scope with you honestly.

Every Kensington job is different because the homes are different. A 1950s ranch off Arlington Avenue presents one set of conditions. A 1970s split-level above Colusa Circle presents another. Our crews know the difference because we work here regularly, not occasionally.
Why Hale Windows & Doors Is Kensington’s Preferred Window Replacement Company
Kensington homeowners call us because we do two things most window companies won’t. We put the price in writing before anyone picks up a tool, and we tell you exactly who is coming to your door. Every technician arrives background-checked, identity-verified, photo-badged, and pre-announced by name and photo before the visit. That’s our Threshold Standard, and it matters more in Kensington than almost anywhere we work. The steep, narrow streets and recessed entries mean you often can’t see the truck pull up from inside the house. You should still know who’s about to knock.
Spencer Odell, who leads Hale Windows & Doors, set the company’s operating rules in 2009: no vague quotes, no unnamed technicians, no pressure. That’s carried through every Kensington job we’ve done since. If a repair fails, the second visit is free. If the work isn’t right, our 365-Day Done Right Promise means we make it right, no argument needed. Those aren’t marketing lines. They’re stamped on every job.
Energy Efficient Windows in Kensington
Energy Efficient Windows in Kensington aren’t a luxury upgrade. They’re a direct response to what the fog belt does to glass. The marine moisture that rolls off the bay every summer attacks seals and corrodes aluminum frames, while the intense afternoon sun at higher elevations cooks west-facing glazing. A low-E insulated unit (a thin metallic coating that blocks heat transfer while letting visible light through) can cut solar heat gain on those western exposures and reduce condensation on bay-facing glass. In Kensington, we typically recommend low-E with warm-edge spacers and stainless hardware for anything facing the bay or the afternoon sun. Expect to pay $1,100 to $2,400 per window for a quality vinyl or fiberglass low-E unit, installed.
Fogged Glass and Failed Seals
Once the seal on an insulated glass unit fails, moisture gets between the panes and the fogging is permanent. You can’t wipe it off, and the low-E coating degrades. In Kensington’s marine air, this happens faster than inland. We replace the failed unit with a properly spec’d low-E replacement that stands up to salt and damp.
Retrofit vs. Full-Frame on Kensington Homes
Many 1950s and 1960s Kensington homes have original aluminum frames that hold glass fine but lose thermal performance and corrode at the corners. A retrofit insert (new sash and glass inside the existing frame) costs less and disturbs less trim. But when the frame itself is pitted or leaking, full-frame replacement is the honest fix. We’ll tell you which one your house actually needs.
Window Replacement Company in Kensington
A Window Replacement Company in Kensington has to handle more than just swapping glass. The steep hillsides, narrow access, and recessed decks mean a big share of the work involves rigging, stair access, or craning units over the roofline. We do that. It’s routine for us because it’s routine for Kensington. But the harder part is what’s behind the wall: undersized headers, failed flashing, and water damage hidden behind stucco or redwood trim. When we open a wall, we inspect what’s actually there, and if something needs repair, we price it in writing and get your approval before we proceed. No surprise invoices. No “while we’re here” additions.
Full Frame Replacement
When a window or slider has rotted framing, a failed sill, or structural movement from the hillside, the whole unit has to come out. We demo to the rough opening, repair or replace framing, install new flashing, and set the new window properly. In Kensington this often means matching stucco or redwood trim details on the exterior, which we do carefully so the replacement doesn’t look like a patch.

Insert Window Replacement
If the existing frame is sound, we install new sash and glass inside it. This is faster, less intrusive, and costs less, typically $900 to $1,900 per opening. Inserts make sense for many of Kensington’s mid-century fixed windows, especially where the original aluminum frame is still structurally solid and you want to preserve the original stucco exterior.
Trusted Brands We Service in Kensington
We install and service windows from CGI, CWS, and ECO Window Systems, among others. We stock common replacement parts and hardware for these lines so Kensington customers aren’t waiting on a warehouse across the country. If you have an aging CGI slider that’s seized from salt air, or a CWS unit that’s fogged, we can usually get the correct replacement components quickly and get the unit operating again. Matching the right product to the job matters more than pushing one brand.
Common Window Replacement Problems We See in Kensington Homes
- Fogged dual-pane glass on bay-facing walls. The fog belt’s moisture loads seals and they fail early. Once fog forms, the unit can’t be cleaned; it has to be replaced with a properly spec’d low-E unit.
- Corroded aluminum frames and seized sliding hardware. Salt air attacks the corners and rollers of original sliders and casements. We regularly replace rollers, tracks, and locks on homes above the village circle.
- Solar-cooked west-facing glass and wood doors. High-elevation homes get brutal afternoon sun that warps wood frames and degrades sealants. Fiberglass or vinyl replacements hold shape better here.
- Hidden framing damage behind stucco and redwood trim. Original 1950s – 70s construction often skimped on header sizing, and years of moisture got behind the trim. We find this on nearly every full-frame replacement on the steeper streets.

FAQs About Window Replacement in Kensington
The fog belt’s marine moisture pushes into failed seals faster than inland Contra Costa. Once the seal on a dual-pane insulated glass unit fails, condensation collects between the panes and the fog is permanent; the low-E coating also degrades. Bay-facing units are hit hardest. Replacement with a proper low-E unit using warm-edge spacers is the only real fix. Call (252) 675-6980 for a free estimate on your fogged units.
Yes, most window replacement work in Kensington requires a permit, especially full-frame replacements or any job that changes the opening size. The permit often triggers code checks on egress, glazing, and energy compliance, and if we find undersized headers or failed flashing behind the stucco, those fixes become part of the scope. We pull permits, get inspections passed, and put every code-triggered repair in writing before we do it. Call (252) 675-6980 and we’ll explain what your specific project triggers.
We rig temporary bridges from the roadway or use a crane when the street is too narrow for a lift. On a steep street above the Kensington village circle, we replaced a fogged dual-pane slider and three full-height fixed units recessed behind the deck by rigging a bridge and setting the new sliders with a crane. The homeowner noticed less condensation within the first week. Call (252) 675-6980 and we’ll assess your access situation in person.
Yes, especially on west-facing glass at higher elevations that takes intense afternoon sun. Low-E insulated glass blocks a meaningful share of solar heat gain, so your cooling load drops. Exact savings depend on exposure, glass area, and how many windows you replace, but homeowners with full-height western glazing report noticeable comfort changes. Call (252) 675-6980 to get a written estimate for your specific glass.
For Kensington’s fog and salt air, we recommend low-E insulated glass units with warm-edge spacers and stainless or corrosion-resistant hardware. We install and service CGI, CWS, and ECO Window Systems products, and we stock common replacement parts for those lines so Kensington customers aren’t waiting on backorders. Call (252) 675-6980 to talk through the right glazing for your exposure.
