"We had Window World replace 36 windows in our home.  The entire house including the basement windows.  
These guys are so amazing!  They did the entire job in 3 days.  The old windows were original to our 1918 house, which can be a little complicated.  The replacement windows are vinyl, and a number of them needed to match our interior wood trim.  The window mullions very closely match the old windows.  They are double hung and have all the great features that can be that Window World offers.  
New windows are probably one of the best in vestments in our home.   We could not be happier and I would happily recommend them to anyone.

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

Windows FAQs, answered by experts

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.

It depends on the insurance company policy, but many companies will offer a discounted rate if you install impact or hurricane windows as they reduce the chance of damage to your home. If you are interested in this perk, make sure to discuss it with your insurance company, as they will likely need your windows to meet certain standards, such as those set by the American Society for Testing and Materials.

Yes, replacing windows can boost your home’s resale value by improving its curb appeal, energy efficiency, and comfort. The return on investment (ROI) varies depending on the types of windows you install, but most homeowners see an ROI of around 60% to 70% of the cost of the window installation, according to the Remodeling 2024 Cost vs. Value Report. 

Yes, triple-pane glass windows cost more than double or single-pane windows. You’ll eventually get that money back in energy savings. Depending on how much you pay for the installation, you could recoup your costs in 10 to 20 years. Triple-pane windows have extra layers of glass, which improve insulation and help save money in long-term heating and cooling costs.

Storm windows are well worth the cost, especially if you live in an area that experiences extreme weather, like hurricanes, a lot of snowfall, or high winds. These windows not only help keep you and your home safe during a storm, but they can also save you thousands in storm and window damage costs.
