"Local Window Service was fantastic. Every other company i reached out to was trying to get me to replace a minimum of 2 entire windows which could take a minimum of 2 weeks to get everything needed. I only needed the glass replaced for one window..
When I spoke with Igor, he helped me assess my situation over the phone and gave me options to take care of the crack on the window. He came out next day and finished the glass replacement in only a few hours.
I cannot recommend this company enough. Igor was outstanding and the workmanship is unmatched. I will definitely be recommending them and using them when I need it in the future!"
"Called them to see if they could fix two windows that would not open. Cost to replace was $2000 a window. They came, determined they needed new springs and were able to replace and fix the windows for less than 1/10th the cost to replace them. Both gentlemen were friendly and very professional. Will definitely call them if i have any window needs."
"Igor and his partner did an excellent job repairing my rotted sash. Then end product looks great and feels solid. If I didn't already know it, I would not have been aware that it was a sash that had been repaired."

Why Choose Our Window Repair Contractors

Window Repair Prices: Most Windows Don't Need Replacing
Replacement companies quote a whole new window for a problem that usually lives in one part. Here's what that difference looks like.
Replacing the window
typical installed cost, per window
- Whole unit removed, even the parts that work
- Interior & exterior trim often redone
- Weeks of lead time on custom sizes
- Original wood & character lost
Repairing what failed
most repairs $150–$700 — see table below
- Only the broken part is fixed
- Trim, paint, and frame left untouched
- Many repairs done in a single visit
- 20-year glass / 3-year wood warranty
