"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."

"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

Mulled windows are often more expensive than standalone windows. However, this is mostly because mulled windows tend to be larger than standard windows, meaning they require more materials and labor to manufacture and install, both of which drive up the cost. If mulled windows take up the same square footage as separate windows, they should cost about the same unless you need to reinforce your exterior wall to support the larger wall opening.

To tell if a window is single or double-pane, focus on the edge. Double-pane windows have two glass layers separated by a spacer, which you can usually see around the edges. For single-pane windows, it’s just one sheet of glass. Another easy trick: shine a light at the window—single-pane glass reflects once, while double-pane glass reflects twice. Lastly, if you feel both sides of the glass on a cold day, double-paned windows will feel warmer because of the insulating gap between the panes.

New window installation costs range from $300 to $1,500 per window, depending on size, material, and energy efficiency features.

Casement windows are safer against intruders than double-hung windows because they are extremely difficult to pry open from the outside. However, if you’re concerned about young kids or pets, double-hung windows have safety features you might prefer. With double-hung windows vs. single-hung or casement windows, you can lock the bottom sash and open just the top sash to keep children and dogs or cats safe.

Yes, every window needs a lintel. The lintel is necessary for redistributing the load above the window to the walls around the window. Windows aren’t meant to support a load, so lintels are an important part of a window installation. If you go to replace your windows and discover there are no lintels, you may need a window company or structural engineer to install lintels for your new windows.
