"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

While plywood will keep winds and debris from shattering your windows from the outside, window film can help protect your windows from the inside. Window film can keep a window from shattering. If your windows break, the film can hold the shards of glass in place, reducing the risk of cuts.

While you may sometimes see window film marketed as "hurricane window film," note that it doesn't provide sufficient hurricane protection on its own. It's no substitute for plywood, storm windows, or hurricane shutters.

No, windows cannot be made 100% soundproof. Even the most advanced setups still allow some sound to pass through because windows are designed to let in light and are not completely sealed from the outside. While you cannot achieve complete silence, significant noise reduction is possible, with some noise-reduction windows blocking up to 95% of outside noise.

The goal is to minimize air gaps, add mass, and reduce vibration. To block out as much noise as possible, consider hiring a professional to install new double-pane, triple-pane, or laminated windows. You can further enhance soundproofing with airtight seals, glass inserts, shutters, or sound-dampening curtains. With the right upgrades, you can block out traffic, neighbors, and other city noise to a much quieter level.

Yes, professional window cleaners will clean the surface of the glass on both the inside and the outside. They will usually clean the tracks for your windows, check and clean the weatherstripping, and even disassemble parts of your window, if necessary, to clean and lubricate interior components and moving parts.

A window may fail because of age, defective mechanisms, or moisture. Depending on the issue, the window may be fixed with simple repairs. Otherwise, you’ll have to invest in replacing it. You can avoid damaged windows but keeping up with window maintenance.   

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.
