Professional window repair across the Bay Area

Whether you are dealing with a fogged double-pane unit in a Menlo Park craftsman or a stuck sash in a San Francisco Victorian flat, window repair is all about restoring function and clarity. NorTech connects you with background-checked, vetted local providers who handle broken glass reglazing, failed seal replacement, sash realignment, hardware swap-outs, and screen re-screening — at a price you approve before any work begins. No hourly guesswork, no surprise invoice at the end of the job. From the Peninsula to the East Bay and South Bay, your window repair provider arrives with the right materials to get your windows working right again in as few visits as possible.

Every common window problem, one trusted platform

Bay Area windows take a beating: salt air and marine layer on the coast fog up insulated glass units, seasonal settling in older East Bay Victorians throws sashes out of square, and years of UV exposure degrade glazing compound and screen mesh alike. NorTech connects you with providers who tackle the full range of interior window repair — reglazing single-pane glass, replacing failed seals in double-pane units, repairing or replacing broken balances and sash locks, swapping out worn cranks and latches, and re-screening torn or sagging window screens. The platform connects providers with single-family homes, multi-unit rental properties, high-end residential, rental turnovers, property managers keeping units rent-ready, and short-term-rental hosts who need repairs turned around fast before the next guest checks in.

From a stuck sash to a failed double-pane unit

Windows fail in different ways: hardware that no longer latches, weatherstripping that lets drafts in, a cracked single pane, a sash that will not stay up, or a double-pane unit that has fogged between the glass. Your provider inspects the window, repairs or reglazes it, and replaces failed glass units or whole windows when repair is not enough. You pick the repair type on the booking screen and add windows, with storm windows and reframed openings as separate options.

Window replacement, one window or the whole house

When a window is beyond reglazing — a cracked double-pane unit, a frame too warped to seal, or you're just ready for something more efficient — the same provider who repairs windows can replace them, priced per window with an option to resize or reframe an out-of-square opening. Replacing one drafty bedroom window or every window on the house is booked the same simple way, with the price confirmed before anyone measures a single pane.

When to book window repair, installation & replacement

A double-pane window has developed a milky or foggy film between the panes, blocking the view and signaling a failed seal.

A window sash swells shut in the winter rains or drops and refuses to stay open without a prop — a classic sign of a failed balance or warped frame.

The crank, latch, or lock hardware on a casement or awning window is broken, making the window impossible to secure or open fully.

A single-pane window has a crack or chip that lets in drafts, and the old glazing compound around the glass is crumbling away.

One or more window screens have a torn mesh, a bent frame, or have pulled away from the spline, letting insects in during spring and fall.

You are prepping a rental unit or short-term rental for turnover and need sticky, drafty, or visually damaged windows repaired before the next occupant arrives.

90-Day Warranty

Backed by your provider’s warranty. If covered work fails, your provider makes it right — free.

Frequently asked

Window Repair, Installation & Replacement — common questions

The repair type is the first choice (hardware or weatherstripping, reglazing a single pane, or re-screening), then how many windows. Replacing whole windows, resizing the opening, adding storm windows and replacing a fogged double-pane unit are separate lines. The total for your list is shown before booking.

Yes. Every window repair booked through NorTech is backed by a workmanship warranty of at least 90 days. If the same issue returns within 90 days of the completed job, your provider will make it right at no additional charge. Before-and-after photos are taken on every job so there is a clear record of the work that was done.

In many cases the insulated glass unit (IGU) itself can be replaced without touching the frame, which is a much less expensive repair than a full window replacement. Your provider will assess the sash and frame condition on-site and give you a clear picture of whether a glass swap solves the problem.

Vetted providers on the NorTech platform replace sash locks, cam locks, casement cranks, awning operators, spiral and block-and-tackle balances, tilt latches, and pull handles. If you are not sure what the broken part is called, describing the window style and what it is failing to do in the booking notes is enough to choose the right provider.

Most single-window repairs — a screen re-screen, a hardware swap, or reglazing a cracked single-pane — are completed within one to two hours. Jobs involving multiple windows or a sash that needs to be removed, refit, and rehung may take a bit longer. Your provider will give you a time estimate when the appointment is confirmed.

For interior window repair, someone does need to be present to provide access to the windows being serviced. If you are a property manager or short-term-rental host coordinating access for a tenant or cleaner, you can note that in the booking so your provider can coordinate directly.
