"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, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

Sometimes, you can buy windows directly from the manufacturer, and it may be cheaper than buying through a third party or wholesaler. Manufacturers may also offer more options, including custom shapes and features, or better warranties if you purchase through them directly. 

However, some companies limit the ability to buy from them, especially if you need standard pre-fabricated sizes, so don’t expect this service from every manufacturer.

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.

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. 

Arched windows are slightly more expensive than standard rectangular ones, but they only cost $50 to $100 more per window. However, adapting a rectangular wall opening to accept an arched window can add $200 to $400 to your total, making them a more expensive option over sticking with a standard window replacement.
