Most average sized residential projects (10 to 25 windows) take about 3-4 weeks from start to finish, but the schedule depends a lot on the size and complexity of the windows we’ll be restoring. Our production team will contact you once your proposal is approved to work with you to customize the schedule to meet your needs.

If you have storm windows then those provide protection in the interim. If you don’t have storm windows we install ½” plywood in the openings to protect your home from weather. We use security screws that require a custom drill bit to remove to make sure you are safe against break-ins. We also offer polycarbonate (plexiglass) window coverings instead of plywood for an additional charge if you’d like to keep the light shining in while your sash are away.

We are an EPA RRP certified firm and our team are trained in working safely with lead paint. While working onsite we create a plastic bubble around the windows we are restoring to keep any dust from spreading outside the work area. All our scraping tools are attached to HEPA vacuums which are the industry standard for protection against airborne lead particles. When finished we vacuum every surface and meticulously wipe everything down with TSP, which is a safe cleaner designed to carry away any lead residue. We perform a white glove test on our way out and won’t leave until you’re satisfied things are clean. All debris is hauled off by us and disposed of at our facility (not your trash can).

Yes they can! The #1 reason any window is inefficient is air leakage and double-paned glass does nothing to fix that. During the restoration process we replace all the old putty and reinstall the glass in fresh putty which seals drafts around the glass. We also modify the sash to fit your frame precisely as needed. We then use our proprietary 100-year weatherstripping system to block drafts yet leave the windows able to operate smoothly creating a draft-free and beautiful historic window. For added efficiency you can also add Indow inserts which can help your original window not just meet but exceed the current energy codes! If you’d like more info on Indow inserts ask your Sales Specialist.

All broken glass is replaced during the restoration process with new ⅛” annealed glass unless requested otherwise. If we break any antique glass during our work (and it does happen) it is replaced with the type of glass that was broken (ie. antique for antique, tempered for tempered). There are glass upgrade options for safety, noise, and efficiency available. If you’d like to discuss these options please let your Historic Preservation Advisor know.
