"From start to finish, Steve was a dream to work with. First, he educated us on the different kinds of films to put on our new windows. He left us with three different patches of film on our window for a week so we can make a decision based on what kind of light and how it looks with different weather patterns. During the installation process Steve was a professional. Explained the entire process step by step. He was efficient, kind, and informative. His price was fair, his work and performance were off the charts, and above all, he was just a great guy. We are grateful we found him and our new home looks better than before!"

"I would highly recommend this company! I have an older home and they repaired all of my original double hung windows. Each window had different issues I contacted them and they came and did an estimate for the work. They also explained exactly what work would be done. They were very thorough and transparent. They did the estimate in the fall and the work was scheduled in the spring. They came on the date that was scheduled, amazing! They were extremely reliable, and showed up for all work as scheduled.They did beautiful work. It is such a pleasure to be able to open all my windows!. The business is very well run, very professional. From the lovely woman in the office to the gentlemen that came to work at the house, they were all terrific. I can't say enough about this company and the quality of their work. I feel the pricing was fair for the job and workmanship."

"Overall, extremely pleased with outcome. Windows and exterior trim came out excellent. Also had exterior doors and deck sliders done with awesome results. The windows come with a lifetime guarantee, and Morgan likewise guaranteed the installation. PJ the crew chief was a craftsman and highly skilled carpenter. Had 21 windows installed and the Morgan guys really worked hard and efficiently. Money well spent."

"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."

He was Timely , Profesional, effecient and had my windows and doors spotless. I live in a wooded area with over 40 windows on my home and 2 sliding doors. I will be calling him back to service my windows and doors again and highly recommend him to anyone looking to do the same."

Windows FAQs, answered by experts

Bay windows and garden windows differ in both size and window angle. Garden windows are smaller than bay windows and extend from the house at 90-degree angles, creating a box-like shape. Bay windows, often much larger than garden windows, consist of three windows set at 25- to 45-degree angles to jut out from your home.

Yes, caulking windows is worth it. Because moisture and air leaks are big sources of common window problems, caulking can be an inexpensive and easy way to eliminate both water and air from getting in. 

If your window well fills with water, first remove the water as soon as weather conditions allow, using a pump or wet/dry vacuum. If water has seeped into your basement, you may need to call a professional to assess the damage. Once the water has been pumped out of the well, check the drainage at the bottom of the well and clear out any blockages.

Egress windows are typically required for basements with habitable space or living quarters. Not all basements or lower levels require egress windows. However, egress windows are required in homes with living spaces such as bedrooms and living rooms in a basement. The International Residential Code and International Building Code require sleeping rooms to have a specific size egress window. Check your local building codes to confirm the requirements in your area.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.
