"Highly recommend Ecoview for anyone doing their windows. We had their team install two dozen windows in our home and they were in and out in a day and a half. My wife and I work from home and they were very respectful of our time, kind, and professional. Thank you!"

"Excellent from start to finish. Quick turn around time from when the contact was made to arrange for the work and when to job was finished. Rudy, arrived on time and texted me that he was on his way. He is very professional. He knows windows. I cant believe how good my windows look, including removing some silicone . I can only say the truth, he is great. I already have my neighbors taking his card to schedule an appointment. Thank you Rudy."

"Peter and his team did a wonderful job of presenting the product, discussing the job, giving a fair price, constant communication, as well as a wonderful install process. We would absolutely recommend this company for vinyl siding replacement and will be calling them for windows in the future."

"I'm so happy with my new windows! My only regret is that I don't have more windows to replace! Aaron and his team were a dream to work with - communicative, friendly, and direct. They worked with me to scope out exactly what I wanted and they were very transparent and fair on price. The installation team was efficient and respectful, making sure everything was done to the utmost standards. My windows look amazing but more importantly they work fantastically! I was shocked at how much quieter and cooler my house was after the new windows were installed, and they are so much easier to keep clean. I will be recommending Thermo-Seal to everyone!!"

"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."

Windows questions, answered by experts

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

To tell if a window is single or double-pane, focus on the edge. Double-pane windows have two glass layers separated by a spacer, which you can usually see around the edges. For single-pane windows, it’s just one sheet of glass. Another easy trick: shine a light at the window—single-pane glass reflects once, while double-pane glass reflects twice. Lastly, if you feel both sides of the glass on a cold day, double-paned windows will feel warmer because of the insulating gap between the panes.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

Yes, you absolutely need a permit to add a window to your house. Your contractor can likely obtain this permit on your behalf. Ask about this when getting quotes from multiple window contractors.

The best way to clean outside windows is by using a garden hose. Start by spraying the windows with a high-pressure stream to clear off loose dirt and grime. Then use a mixture of hot water and dish soap and scrub the windows with a sponge. Rinse off the soapy water with the hose. Before you finish up, spray the windows with a solution of vinegar and water and wipe them down with a microfiber cloth.
