Professional Window Repair in Montgomery County, MD

A window that will not open, close, lock, or stay up is a daily frustration and a security and energy problem. Jacob has been repairing window hardware throughout Montgomery County for over 19 years. He diagnoses what is actually wrong and fixes the hardware rather than pushing for a full replacement you may not need.

Whether it is a broken balance, a worn latch, a sash that has swelled and will not move, or weatherstripping that is letting cold air in, Jacob handles it properly.

Based in Gaithersburg, Property Renovators is the local choice for homeowners who want the job done right the first time.

Frequently Asked Questions

Jacob gives you an honest assessment. Hardware repairs and weatherstripping are almost always worth it. Fogged double-pane glass from seal failure can sometimes be addressed with glass unit replacement rather than full window replacement.
Yes. The balances on double-hung windows wear out over time. Jacob replaces them so the window stays at any height you set it.
Yes. Jacob cuts the paint line cleanly with a utility knife or window zipper, frees the sash, and checks the hardware and balance before leaving.
Fogging or condensation that appears between the two panes of glass and does not wipe off from either side means the seal has failed and the insulating gas has escaped. Jacob can assess whether the glass unit can be replaced without replacing the full window frame.
Most hardware repairs take one to two hours per window. A full weatherstripping replacement on several windows can take two to four hours.
