"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

Bay windows are not easy to install because they are heavy and require specific tools and woodworking experience. You’ll also need to install a roof cab, flashing, and shingles. Ensuring the window is level and sealed can be tricky but it is important because it prevents air leakage and water from entering your home. Most often, an experienced window pro should install bay windows.

Whether you need a permit to install a bay window depends on the project's scope. Replacing an existing bay window typically does not require a permit. However, if you are adding a new bay window, requirements can vary. Adding a new bay window to the front of your house usually requires a building permit, while adding one to the side or back of your house often does not. It's always best to check with your local municipality to confirm the specific requirements in your area. Additionally, if you live in a historic district, you should consult your neighborhood association to ensure your project complies with their construction guidelines. If you're unsure about the process, a professional can provide guidance.

Garden windows last about 15 to 30 years, depending on the materials, ongoing maintenance, and local climate. Fiberglass and wood windows tend to have the longest life spans as long as you keep up with cleaning, lubricating, and refinishing them. Make sure to inspect your windows about once a year for signs of trouble, like worn-out seals, frame damage, or cracks in the panes.

The amount of time window lintels last is based on the environment they’re installed in and the material that’s installed. For example, a steel lintel installed in a temperate climate will always last longer than a wooden or brick lintel installed in an area with tons of rain, snow, and wind. No matter which material you choose or where you live, proper maintenance will ensure your lintels last as long as possible.

There are many standard window sizes. The most common windows, single or double-hung models, typically range from 2-feet by 3-feet up to 4-feet by 6-feet. Of course, sliding windows will be wider than they are tall, though the standard sizing follows the same measurements.
