"I cannot say enough positive things about Action windows. From the informative and non-pushy sales person to the incredible installation crew, it was a very positive experience. The price for the high quality windows was very competitive and fair. The installation crew was on time and very considerate. I work from home and they really worked around me. The cleaned up everything"

"I liked that there was no nonsense. Their salesman was straightforward and the price was fair. We were also impressed with the installers. They installed all the windows in 1 day and they look great. I'm happy I chose them."

"Was very nervous hiring someone to do my roof. I’ve had bad experiences in the past. The salesman Nick met me at my home. Gave me in full detail a step by step breakdown of how the project was going to unfold. I just got my deck done a month prior. He assured me that everything would be covered, and the clean up would be thorough. On the day of my installation, not only was property protected. The owners of the company Zak, and Rich came out personally to bring insulation board to cover my railings of my new deck. I was very impressed with that, the detail and follow through with everyone involved with the project. My wife and I are planning to get the roof done on our rental property this year, and I know I only need to make one call to get the job done right. I highly recommend A1 Home Improvement for any outdoor project you have."

"We hired Budget Dry to review our basement problems and hired them to do the waterproofing project, install new basement windows, install the Santa Fe dehumidifier, and recently they installed our back-up battery system. We highly recommend them -always courteous, get the jobs done quickly and neatly, and always respond when we need their advice/want to purchase new filters. A great company!"

Customers say: Quick response

"Stefan Korn and his crew removed and replaced all of the rotted and ripped screen-panel walls and doors that made up our screened porch with his far superior screen/frame products -- dog-proof screen on the lower panels and regular screen on the top. He and his crew performed the work in an exceptionally professional and timely fashion and somehow managed to keep everything remarkably neat and tidy during the process. We couldn't be more pleased with the finished product. We also truly enjoyed working with Stefan and his men. They have our highest recommendation. Their work is worth every penny."

Windows FAQs, answered by experts

Yes, professional window cleaning is worth the investment. Regular deep cleanings help keep your windows looking new, extend their lifespan, and boost your home's curb appeal. By removing dirt, dust, and other debris, you can reduce the risk of damage and accelerated wear to window frames and components. It also improves your home’s energy efficiency by keeping insulation and weatherstripping in good working order, potentially lowering your energy bills. Furthermore, annual or bi-annual cleanings can help identify problems like leaks or cracks early, before they escalate into expensive water damage. You can often recuperate the cost of cleaning through energy savings and by avoiding premature window replacement.

Costs depend on window size, type, material, and labor. Custom shapes or sizes typically incur higher expenses; full installation includes removing old windows.

Bay windows are not easy to install because they are heavy and require specific tools and woodworking experience. You’ll also need to install a roof cab, flashing, and shingles. Ensuring the window is level and sealed can be tricky but it is important because it prevents air leakage and water from entering your home. Most often, an experienced window pro should install bay windows.

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.

The biggest disadvantages of low-E windows have to do with cost and, depending on your personal taste, appearance. Low-E windows cost more than traditional windows—typically between $300 and $1,000 per window, plus installation costs. Though they can save you money in the long run, low-E windows have a hefty upfront price tag. Additionally, low-E windows have a slightly different look than traditional windows. While some people don’t notice it, others say the low-E coating gives windows a hazy look.
