"Universal Windows Direct of Manchester provided not only prompt, professional, and preferred service, they also provided a peace of mind for the service they provided. The owner personally visited my home and suggested several suggestions to address my concerns. Never was I pressured, pursued, or offered a product which I had not asked. Universal Windows Direct offered me the security that I knew that this was a company of integrity and honesty. So much so, that when the work was done, I was not home. Unbelievable! And, when I returned home from work on the day of my new window installation, all I could see was the view from my new window...windex'd cleaned, with no evidence that they has ever been in my house. Universal Windows Direct of Manchester treated my home- as their home, with respect and responsibility. They not only met my concerns, they under promised and very much over delivered. Would I use them again...you bet, in a flash! Thank you Universal Windows Direct of Manchester. Doug Robinson, Derry, NH 03038"

"I contacted Scott Harlow through Angi and I couldnâ t be more pleased with his work. Scott removed the old film on 15 of my sunroom windows and replaced it with new UV and heat retardant film. The windows look fantastic. Not only is Scottâ s work excellent, but he is also very pleasant, prompt and a true expert at his craft. I recommend him highly and without reservation."

"I liked that there was no nonsense. Their salesman was straightforward and the price was fair. We were also impressed with the installers. They installed all the windows in 1 day and they look great. I'm happy I chose them."

"Working with Devon to complete the roofing project was essentially painless. A very good communicator and hard-working individual, Devon was patient and kept his schedule open as we worked out preliminary issues prior to the work beginning, and then kept me up to date as work began and progressed to completion. He also sent pictures and short videos as well which were important as I was in a different part of the country during most of the work. While there are always hiccups along the way, the process was very good and I will be connecting with Devon again in the near future for more work to be done. I suggest you do the same."

Windows FAQs, answered by experts

In addition to window well covers or bars, you can take a few more steps to boost basement window security. Try motion-activated lighting; it scares off potential intruders by lighting up when someone gets too close. Strengthening your window glass with impact-resistant security film can also deter forced entry. A dependable home security system with window sensors and cameras offers real-time monitoring and alerts for added protection. Lastly, fostering good relationships with neighbors can establish a supportive community watch network, enhancing your home's safety.

The average lifespan for a casement window is around 20 years, but some higher-end casement windows with more durable frame materials can last up to around 40 years before you need to replace them. You’ll need to carry out routine maintenance and window cleaning—and, on occasion, casement window restoration—to extend the lifespan of your casement windows. But they tend to wear more slowly than windows with sliding sashes because the weatherstripping sees minimal friction.

There are a few reasons your crank windows might not close. First, determine if your window crank is working properly and opening and closing the window when you turn it. If it’s not, the crank may need replacing, cleaning, or lubricating. Another reason your windows aren’t closing could be dirt and debris in the window hinges or sash. Finally, make sure your window lock operator is set in the unlocked position and isn’t blocking the window from fully closing. If you’re still having trouble closing your window, it may be worth consulting a local window contractor.

When it comes to your pocket, opting for energy-efficient windows can lead to an average of 12% in energy bill savings. That totals to yearly energy savings between $100 and $600. However, the exact amount you’ll save hinges on factors like your local climate and the number of windows in your home.

Yes, it is generally better and more cost-effective to replace all your windows at once. Contractors often lower the per-window labor and material costs for larger projects, saving you money in the long run. Installers may also quote a flat rate for overhead, making multiple small jobs more expensive than one large one.

Replacing all windows simultaneously offers other advantages:

  • Aesthetics and Home Value: It creates a cohesive style and uniform energy efficiency, which is appealing to potential home buyers.

  • Efficiency: The entire replacement process, which can take several weeks, is completed in a single, more efficient project.

However, replacing all windows requires a significant upfront investment. While you can replace just a few windows, experts recommend replacing at least five to eight at a time to avoid high overhead costs. An exception is when a single window is damaged; in that case, it can be replaced on its own.
