We are dedicated to promoting preservation and sustainability!


Unlike other companies that replace the whole window or cut only a portion of the rotten part, or use epoxy or wood filler, our company replaces the entire damaged wooden part of the frame to restore the window to its original condition. The new replacement part is made out of pressure-treated lumber which is water, rot and insect resistant.

We can help you preserve the authentic custom windows and doors you already have. Our excellent reputation and long list of satisfied clients attest to our superior craftsmanship, attention to detail, honesty and integrity. We work on Andersen, Pella, Rockwell windows, as well as numerous other windows manufactured between 1990 and 2020.  

Stavaru Window Renovation Specialists is a carpentry company that specializes in wood window restoration as an alternative to window replacement. The company offers evaluation and restoration of residential and small commercial building wood windows. Additional services include repairs of areas around the windows, doors, siding, and drywall. Restoration services have primarily been used for the preservation of historic buildings. But reduced costs and environmental considerations provide a great opportunity for all households.

How does the process work?

After you contact us, we can discuss your needs and issues with your windows. You may send us pictures of your windows and damaged area, or we may schedule a time for an in-person consultation. During that consultation, we assess the condition of your windows, evaluate your personal needs, prepare an estimate, and address any questions and concerns that you may have. Please be aware that estimates are not always 100% accurate due to the inability to inspect areas within walls or under insulation. If additional repairs are needed, we will discuss all options with you before proceeding.

When you decide to work with us, you contact us to prepare a schedule for the work to be done on your windows. All work is conveniently done at your location, outside the building. Work is limited to specific repairs and could be completed within a few days. The repairs can be phased to coincide with an exterior painting or another maintenance project, making the repair process very efficient for you. Also, because of the limited amount of materials used, there is no need for landfills for disposal. Please be aware that due to the unpredictable weather and amount of damage in some windows, projects may take more or less time than initially projected.

Our goal is to not only help you preserve your custom wood windows and increase the value of your home, but to make the process easy and enjoyable for you.
