Call (252) 675-6980 and we’ll give you a written price before anyone touches a screwdriver.

We know Sunnyvale lots. We know the 1950s ranch houses off El Camino Real, the newer townhomes squeezed in near Mathilda Avenue, and the way marine-layer air works on metal window parts in the west-side neighborhoods. Our Window Repair crews stage trucks in tight driveways, respect work-hour noise rules, and tell you by name and photo exactly who’s coming before the visit. That matters when you’re home alone with kids or just don’t want a stranger at the door.
Why Hale Windows & Doors Is Sunnyvale’s Preferred Window Repair Company
We’ve been repairing and replacing windows since 2009 as an independently owned operation within the Threshold Group, and the jobs we see in Sunnyvale have a very specific pattern. It’s not the heat that’s hard on windows here. It’s the moisture. The bay fog that rolls through the morning hours leaves a film of salt and damp on metal frames, flanges, and hardware, and after forty or fifty years, that film turns into rust. We see it constantly on the original aluminum sash in Lakewood and Cherry Chase ranch homes.
Every Sunnyvale job starts with a written price. No verbal estimate that changes later. The figure we hand you before work begins is the figure on the invoice. That’s a Hale policy, not a sales tactic. And every repair is covered by the 365-Day Done Right Promise. If the fix isn’t right a month later or ten months later, we make it right. Named in writing, stamped on the job.
Before any tech drives to your Sunnyvale home, you get their name and photo sent to your phone. They’re background-checked, identity-verified, uniformed, and wearing a photo badge when they knock. We call it the Threshold Standard. It exists because opening your door to a stranger shouldn’t be something you have to think twice about.
Window Crank Repair in Sunnyvale
Window Crank Repair on a casement or awning window in Sunnyvale typically costs $95 – $185, depending on whether the operator arm, the crank handle, or the full mechanism needs replacing. In the older ranch homes around Cherry Chase and Lakewood, crank failures usually come from corrosion in the gear teeth after decades of coastal moisture. In the newer townhomes near downtown, it’s more often a stripped gear from heavy use or a bent operator arm from forcing the window open against a sealed winter frame.
What the Job Involves
We remove the operator housing, check the gear and arm for wear or rust, then install the right replacement unit. On PGT and CWS casement windows, parts are usually stock items for us in Sunnyvale. If the sash is fine and only the crank is shot, you’re paying for the hardware and the labor to reset the window’s alignment, not a whole new window. That’s the difference between a $140 repair and a $900 replacement.
When to Call Sooner Rather Than Later
A crank that grinds or slips is a warning sign. The window is working out of its track, and each turn of the handle bends the arm a little more. Left alone, the sash stops seating fully, and the air gap that creates lets marine air and winter rain work into the jamb. In a Sunnyvale winter, that’s when the wall behind the window starts holding moisture.
Window Screen Repair in Sunnyvale
Window Screen Repair across Sunnyvale runs $45 – $110 for a standard rebuild with new mesh and spline, and closer to $75 – $140 if the frame itself is bent or corroded and needs replacing. Screens in Sunnyvale take a unique beating. The salt air on the west side, especially in neighborhoods closer to the bay, corrodes aluminum screen frames faster than you’d expect, and older wood-framed screens in Cherry Chase often rot along the bottom edge after a few wet winters.
Screen Mesh Choices for Local Conditions
Standard fiberglass mesh is the most popular and the least expensive, and it holds up fine on the east side of Sunnyvale. Closer to the bay, we recommend a tighter-woven mesh that resists salt degradation a little better. If you’ve got pets or young kids pushing against screens, a heavier pet-resistant mesh will survive a lot longer than standard. We stock the common mesh types measured for the window sizes we see in Sunnyvale’s 1950s and 1960s tract houses, so most screen jobs are one visit.
Frame Repair vs. Full Replacement
If the frame is still square and the corners are tight, a re-screen is straightforward. If the aluminum has pitted or the corners have pulled apart, it’s usually cheaper to replace the frame than to patch what’s left. For condo and townhome units near downtown, HOA rules sometimes specify screen frame color and mesh type, and we’ll match that spec so your unit doesn’t stand out.

Trusted Brands We Service in Sunnyvale
Hale installs and services windows and doors from eight professional-grade product lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. For Sunnyvale specifically, we keep common PGT and CGI replacement parts on hand: crank operators, locking mechanisms, balance springs, and insulated glass units sized for the windows we see most often. That means a repair on a PGT casement in a Sunnyvale home usually doesn’t wait on a parts shipment. Spencer Odell, who leads Hale Windows & Doors, insists we carry what the local market actually uses, not whatever is easiest to order.
Common Window Repair Problems We See in Sunnyvale Homes
- Rusted metal flanges on original 1950s – 1960s windows. In Cherry Chase and Lakewood, the original steel flanges that hold the window into the rough opening have spent sixty years wicking in marine-layer moisture. A repair that swaps the sash but skips the flange seal will leak again by the next wet winter.
- Fogged or failed insulated glass in older replacements. Sunnyvale’s winter storms and summer heat cycles push glass seals to fail, and once the seal goes, condensation settles between the panes. The fix is a new CEC-listed insulated glass unit, not just a cosmetic clean.
- Crank and operator failures on casement windows in townhomes. Near downtown and the tech campuses, tight-spaced units and shared walls mean noise and access coordination matter. A crew that doesn’t park right or can’t get to the window without crossing a neighbor’s entry gets rescheduled. We plan around that before we arrive.
- Sticking double-hung sashes in ranch homes. Original wood framing in 1950s tract houses swells and shifts with the wet-dry cycle. Sashes bind, balances break, and the window refuses to stay up. That’s usually a balance replacement and jamb reset, not a whole window.
Pricing for Window Repair in Sunnyvale, CA
Here’s what you’re actually looking at in Sunnyvale. A basic screen rebuild: $45 – $110. A window crank or operator replacement: $95 – $185. A balance spring or tilt-latch repair on a double-hung: $75 – $150. A full insulated glass unit replacement with CEC-listed low-E glass: $185 – $340. A complete window sash replacement in a 1950s ranch home: $225 – $500, depending on size and brand.
What moves the number is access. A first-floor window with a clear path from the driveway is the optimistic end of every range. A second-floor window over a narrow side lot near El Camino Real, where ladder placement is tight and we need a second tech for safe handling, lands at the top. We’ll tell you the price in writing before work starts. Call (252) 675-6980 for an exact quote. Estimates are free.
And one thing we want to be clear about because Sunnyvale enforces the 2022 Title 24 energy standards directly: any replacement glass we install is CEC-listed with the correct U-factor and SHGC for your window’s orientation. That’s not an upsell. It’s the law in Sunnyvale, and it’s why we don’t use generic glass that would fail a post-repair inspection.

FAQs About Window Repair in Sunnyvale
No, a like-for-like repair that doesn’t change the window opening size typically doesn’t need a permit in Sunnyvale. What it does need is CEC-listed glass meeting the 2022 Title 24 standards, because Sunnyvale enforces the state energy code directly. Call (252) 675-6980 if you want us to confirm whether your specific repair falls into the no-permit category.
That’s the classic Sunnyvale flange failure. Winter winds push rain against the window at an angle that summer rain rarely does, and if the original metal flange behind the frame is rusted through, that angled rain finds its way in. The fix is a new flange seal and often a new insulated glass unit, not a roof repair. Call (252) 675-6980 for a written quote.
Yes. We coordinate parking ahead of the visit, keep tools and ladders on your side of the property line, and run the job during Sunnyvale’s permitted work hours. The repair itself is quiet work: remove the operator, install the new gear and arm, test the throw, and clean up. Your attached neighbors may hear a few minutes of hand-tool work at worst. Call (252) 675-6980 to schedule.
Yes. The frame material doesn’t change the glass requirement. Sunnyvale applies the 2022 Title 24 standards to the whole window assembly, and that means the replacement insulated glass unit must be CEC-listed with the right U-factor and SHGC, regardless of whether the frame is vinyl, fiberglass, aluminum, or wood. Call (252) 675-6980 and we’ll spec the right unit for your building.
It mostly changes labor, not parts. If we can’t park at the curb and have to shuttle tools from a block away, or if the ladder has to go over a narrow side lot instead of standing on open ground, the job takes longer. That’s reflected honestly in the written price we give you before work starts. Call (252) 675-6980 for a quote that accounts for your specific lot.
