"John replaced the glass sash on my Anderson casement windows. He did the complete job in one day, at a cost of 15% of the Anderson replacement window quote. I highly recommend Window MD.. They were perfect!"

"Thank you Aaron and Bob for another excellent joy with another window project. We are equally thrilled with the workmanship of the installation and the quality of our new window as we were the last time you did a big window job for us. We appreciate your professionalism and dependability."

"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."

"Alex responded quickly to help me get six very old third story dilapidated attic windows replaced. He and his coworker came, measured and special ordered new windows at a fair price. They did excellent and efficient work in a difficult to work area. If you need windows replaced or repaired Wet Seal is who I would recommend. I appreciate all he did and the windows look great. Thank you Alex"

Windows questions, answered by experts

Bay windows are supported by braces and industrial strength cables, often at the top of the window but sometimes at the bottom. The bay window may need buttress supports if installed on the second floor. Wood screws on the interior also hold the bay window in place. Bay windows are heavy and need proper support to prevent sagging and wall damage. You need to ensure that the support system can hold the weight of the window and the roof cab over the window.

Having a professional caulk your windows will cost you around $50 to $70 per window (or $1.25 to $4 per linear foot), including labor. However, caulking is one of the easiest DIYs there is, and you’ll save a lot of money by getting the supplies and doing it yourself. You’ll only pay $0.05 to $0.20 per linear foot if you DIY this one. Finally, different types of caulk don’t vary too much in price, with most tubes costing no more than $15 apiece (but typically only $3 to $10) at the most. 

There are many high-quality window companies on the market, although Andersen, Pella, and Marvin continue to be the most popular nationwide. Some brands, like Sunrise and Soft-Lite, are popular regionally but may not be available in all parts of the United States. When comparing brands, look for features like increased energy efficiency, strong and durable materials, and long-lasting and all-encompassing warranties.

When your double-hung window upper sash keeps falling down, it means you could be letting out warm air in the winter or cool air from the AC in the summer. That means your HVAC system works harder to warm or cool the house, costing you extra on electric bills.

If the lower sash continues to fall down, it means when you’ve popped open the window for fresh air, it could slam shut. In addition to being inconvenient, this could be dangerous if you have small kids, children, or pets that like to hang out by the window.

Using plastic shrink film over the window will cut down on drafts, which makes the air inside your home feel warmer. Plastic shrink film doesn’t quite have the insulative properties of a new window or of adding insulation inside the window jamb, but it will help. Plus, it’s a cost-effective solution to keeping your home warmer.
