Frequently Asked Questions
You get 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. We replace them so the window stays at any height you set it.
Yes. We cut the paint line cleanly with a utility knife or window zipper, free the sash, and check the hardware and balance before leaving.
Fogging or condensation that appears between the two panes of glass and doesn't wipe off from either side means the seal has failed and the insulating gas has escaped. We 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.
A draft with clear glass means the weatherstripping or sash seal has failed. Fogging between the panes means the insulated glass unit seal is gone. Both cause energy loss but need different repairs. We check which is the actual issue before quoting anything.
Yes, when the frame and sash are in good condition. The glass unit is the component that fails, not the frame. Replacing only the unit restores the insulating performance without a full window replacement.
Yes. If the window is being worked on for a hardware or glass issue, we check the weatherstripping and exterior caulk condition and include those in the same visit if they need attention.
Don't order anything yet. Fogged glass units need to be measured precisely from the existing frame. We take the measurements during the assessment visit and tell you the lead time for the replacement unit.

"Jacob is the best ever. He made my dream come true by installing my catwalk for my cat to the ceiling when no other contractor could handle the job. I was extremely impressed by his expertise and he is definitely someone you can trust. It's hard to come by professionals who are also kind and Jacob is just stellar. I even paid him extra because he did such an amazing job."
