"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."

"We had a 35 year old solarium in great need of repair. The project was complex and difficult, but Wayne had the skills and expertise to replace six large windows and rebuild the solarium. It was a challenging project, and Wayne did an exceptional job. Our "new" solarium adds greatly to the value of our house. Wayne knows windows and doors and he gets five stars from us! Mary Ross"

"Keith worked with me for about 3 months before I decided the final project. Keith was very professional and patient. He gave 3 estimates for which to choose from. He even hired a designer to help with the colors and placement of the panels. Work was started on time and it looks wonderful. I would highly recommend GS Exterior Experts."

Windows FAQs, answered by experts

To ensure the longevity and smooth functioning of new windows, regular maintenance is essential. This includes cleaning the glass and frames, inspecting seals for leaks or damage, and reapplying caulking as needed. It is also important to lubricate all moving parts and operating mechanisms to ensure they continue to operate smoothly.

Storm windows are placed outside of already-installed windows. Regular windows are installed into a frame, offering a barrier to the elements but no special protection. Storm windows add extra protection to regular windows, reduce noise, and improve insulation. Replacing a regular window involves a different process than installing a storm window. 

Most manufacturers have their name imprinted somewhere on the window, such as the spacer bar, hardware, or frame. Other manufacturers will include an identification number printed on the glass itself. If you’re unable to find either of these, then your window was manufactured locally (oftentimes called a “shop window”). 

With a manufacturer name (or even better, the identification number) you can attempt to research the information to find out when the product was made. Keep in mind this won’t tell you when the window was installed on your home, but can get you close.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

Yes, you can absolutely put a screen on a casement window, and most casement windows come with screens. Unlike with a double-hung, single-hung, or sliding window, the screen in a casement window sits on the inside of the window so that the sash can freely open outward. Screens are especially important for casement windows because the large window opening the window provides leaves your home more open to bugs and outside debris than most other types of operable windows.
