"We had the main windows done by Power Windows in 2021 and now we had them do the windows on our outbuilding and mudroom. The entire process has been great from start to finish. The windows are fantastic, keeps the heat out in the summer and cold out in the winter. The sales(Davis, Jack, and Brad) and work crew(headed by Gus) have been very up front and professional. I highly recommend this company."

"Excellent job on the window tinting project. The quality of the work is top- notch, clean precise and professionally done. The tint not only enhanced the look of the home but has reduced the glare and heat, just as I had hoped. Cassandra was respectful of our space and left everything spotless after the job was done. I’d highly recommend to anyone looking to upgrade their home Windows. Outstanding work with a fun personality!!"

Windows questions, answered by experts

Yes, storm windows should be tempered. According to the International Association of Certified Home Inspectors, tempered glass is stronger and can withstand temperatures higher than laminated glass. Tempered glass is important for storm windows because it protects against outside elements and household accidents by not producing sharp, jagged pieces when it breaks or shatters.

Before purchasing, it’s good to weigh the pros and cons of vinyl windows. Vinyl windows offer several advantages over other types of windows. Vinyl windows are more affordable than most other window types, and they’re also very energy efficient. Vinyl windows are also low-maintenance, weather-resistant, and easy to install.

Hopper windows aren’t flawless when it comes to keeping rain and debris out of your house because if there’s wind pushing the precipitation, it could easily get in through the open space. On top of that, hopper windows aren’t potential escape routes the way regular windows are in case of a fire or emergency. If that’s a priority or need, it’s something to consider when choosing a window type.

Using plastic shrink film over the window will cut down on drafts, which makes the air inside your home feel warmer. Plastic shrink film doesn’t quite have the insulative properties of a new window or of adding insulation inside the window jamb, but it will help. Plus, it’s a cost-effective solution to keeping your home warmer.

Whether or not new windows increase property taxes depends on where you live and by how much your upgrade increases your home’s value. Smaller projects likely won’t result in increased property taxes, but it’s always a good idea to err on the side of caution and check. Contact your local county appraisal department for the most accurate information about property taxes in your area.
