"We recently had windows repaired and installed by Ardmor. We were very satisfied with all the repairs and the sliders they installed look great. The servicemen who worked on our project were highly skilled, courteous, and very professional. We look forward to doing business with Ardmor in the future. Bob & Linda Knauss"

"These men were polite and professional. They cleaned my gutters and let me know there was a problem with the gutters pulling away from the house. Unfortunately, they do not do any type of repairs. I would recomment Clear View Window Cleaning to anyone looking for any type of gutter cleaning."

"The Alderfer installers exceeded my expectations.  My experience with the sales person was wonderful.  He walked me through different front door configurations, and was patient, answering all of my questions and offering great options.  The installers were exceptional.  They were able to install the entry door, sliders, basement windows and glass units in 4 days as scheduled, despite the bad winter weather.  They worked diligently, all day long every day.  The work quality was better than I expected.  My old entry door configuration was uneven, due to the house settling over the years, but they were able to work through it, and made it look 100% better than the original.  They even installed exterior lights that I had bought for me, free of charge.  The glass replacements make my old windows look almost new.  Because of the old window frames, 3 glass units cracked when they installed them, but they replaced them and rescheduled the installation promptly, free of charge.   And to top it all off, the installers were so good with my highly energetic dog.  It was a wonderful experience, and I should have done it a long time ago.

"Green star did all 22 windows in my home and 3 entry doors. The entire process was smooth from start to finish. They even got everything installed before their estimated date! They give a lifetime warranty on their products. The first time I cleaned my windows one of them wouldn't shut. I called in and they tried to talk me through it on the phone. When I couldn't figure it out they sent a service tech out and he fixed the problem in less than a minute (it was something I did wrong!). There was no charge for the visit!"

Windows FAQs, answered by experts

Yes, it is generally better and more cost-effective to replace all your windows at once. Contractors often lower the per-window labor and material costs for larger projects, saving you money in the long run. Installers may also quote a flat rate for overhead, making multiple small jobs more expensive than one large one.

Replacing all windows simultaneously offers other advantages:

  • Aesthetics and Home Value: It creates a cohesive style and uniform energy efficiency, which is appealing to potential home buyers.

  • Efficiency: The entire replacement process, which can take several weeks, is completed in a single, more efficient project.

However, replacing all windows requires a significant upfront investment. While you can replace just a few windows, experts recommend replacing at least five to eight at a time to avoid high overhead costs. An exception is when a single window is damaged; in that case, it can be replaced on its own.

Depending on material and size, costs range from $300 to $800 per window.

Yes, most manufacturers offer warranties for materials and performance. Confirm terms before purchasing.

Awning windows can have screens, but it depends on your manufacturer. If your awning window does have a screen, it will be on the interior side so it doesn’t get in the way when you crank the window open. Having the screen on the inner part of the window also makes it easier to clean from inside your home.

There are a few reasons your crank windows might not close. First, determine if your window crank is working properly and opening and closing the window when you turn it. If it’s not, the crank may need replacing, cleaning, or lubricating. Another reason your windows aren’t closing could be dirt and debris in the window hinges or sash. Finally, make sure your window lock operator is set in the unlocked position and isn’t blocking the window from fully closing. If you’re still having trouble closing your window, it may be worth consulting a local window contractor.
