"Tom responded quickly and gave me an estimate on installing two small windows on each side of my fireplace. He said it would take a month for the order and that's exactly what it was. My schedule didn't allow him to come out during the week so he came on a Saturday morning to install windows. He did a great job, cleaned up inside and out and the windows look great. I may consider installing an egress window and I would definitely use Tom's company."

"Ray the owner was on time, worked fast and did a great job. Our house will sell better because of our sparkling windows. He was friendly and even washed the two little windows on our shed for no charge that were not included in the bid.Our bid also included cleaning out our window wells and cleaning those windows. He did an excellent job. His prices are low. He is a veteran and hires veterans in his business. I would definitely recommend this company for windows and gutter cleaning."

Windows questions, answered by experts

Glass block windows are energy-efficient because they are much thicker than traditional glass panes, making them better insulators. They are sealed airtight, which prevents drafts and stops warm or cool air from escaping, helping to save money on heating and cooling bills. Unlike traditional windows that can be opened and closed, sealed glass block windows eliminate the potential for air leaks. For proven efficiency, look for options that are Energy Star rated. The cost for energy-efficient glass block windows is typically around $400 per window, which may be higher than standard windows.

No, it’s not normal for windows to rattle in the wind. If they do, it may signal that there’s a larger problem at play. Common reasons that windows rattle in the wind are because the glass isn’t secure enough, the frame is loose, or the wood is rotting. In any of these cases, you should identify the problem and take steps to fix it.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

Wood windows are often worth the cost because they add more to curb appeal and your home value than more affordable options like vinyl and aluminum. Wood windows also offer better insulation than vinyl and aluminum windows, and they can last about twice as long. As such, they’re more expensive up front but offer greater value and a higher ROI.

One of the best professional cleaning solutions that won’t leave streaks is one gallon of distilled or bottled water mixed with 2 to 4 teaspoons of dish soap. Apply using a sponge in a figure-eight motion, and then use a squeegee to remove the majority of the water and soap. You can finish drying with a piece of old black-and-white newspaper to remove any residue for a streak-free clean every time.
