"We had several windows and doors replaced and I was really impressed with the new windows and doors as well as the professional installation by Perry and his crew. They made sure everything was square, clean, and caulked. Great job! I highly recommend Metropolitan High Performance Windows."

"Overall, I was very pleased with the service. I had six window screens repaired. I was told that there was a minimum of $150.00 requirement. I wasn’t told this in advance, the cost was approx. $22 per window, times 6=$132.00. We settled on $140.00."

"I needed the glass replaced in my sliding door. This company does not do that. But they refereed me to someone who does. They called me almost immediately after I hit the submit button. The gentleman was very professional and the company he referred me to, was also great."

"Needed a new sliding door since ours was old and constantly got stuck. We hired Ameristar and they were so professional. From booking the service, to purchasing the best sliding door, to the installation, everyone was so honest, polite and accommodating to the needs of my home. Now I have a sliding door that is quiet and opens and closes smoothly. Would definitely recommend hiring them if you need any new windows or sliding doors!!"

Windows questions, answered by experts

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

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.

Yes, bifold windows can open inward or outward. Your window manufacturer will label windows as “in-swing” or “out-swing,” which indicates the direction they open. If your installer is ordering windows for you, make sure they know which direction you want them to open. In-swing bifold windows will preserve as much space in your outdoor area as possible. Out-swing bifold windows are great on the second floor, where obstructions outside aren’t a concern.

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

Most modern egress windows installed in basements open outward into a window well, although some older homes have in-swing windows. Egress windows, like casement windows used in other parts of the home, such as bedrooms and bathrooms, may open inward, and these windows are often larger than outward-opening windows.
