We absolutely loved working with Mr. Jim Fowler, him and his crew are incredibly professional, they do a fine job and once the materials arrived - everything went very smoothly. See pic, we are madly in love with our Fleetwood windows! The inspection went smooth bc they did a very fine job!

Windows Unlimited is not just a company for windows but also for doors. My french doors were leaking really bad due to improper installation from the original builder. Got several quotes from different companies and talked to a few business owners; I can certainly tell that Jim from Windows Unlimited is the most sincere, honest, and knowledgeable one among them. Chris and his team worked on replacing the doors and did a fantastic job.

They are very professional and always keep the job site clean. I waited almost a year to leave this review because I wanted to see how the new doors hold up. So far I am very satisfied with the new french doors and workmanship provided by Windows Unlimited.

If you need windows replacement, Windows Unlimited is the place to go. I worked with Jim about three years ago. We had to retrofit the old, single pane windows on our house with new, double pane windows. We also enlarged some of the windows. Jim and his team was very professional. The quotes were detailed and easy to follow. Jim was the only contractor who was willing to quote a mix of two types a Milgard windows and was able to deliver those. He and his team did a great job and finished within the budget. Three years later, the windows installed by Jim still work perfectly.

Windows Unlimited is fastastic! We had a delamination arise with one of our double paned windows installed by a different contractor 15 years ago. Jim from Windows Unlimited came out to inspect it and got enough information to contact the agent for the window manufacturer. Turns out the manufacturer will replace the window at NO COST. Jim refused to take any payment for his involvement and time. He provided outstanding responsiveness and customer service.

I had 3 double-pane windows where the seal had failed and they were fogging up badly. Instead of selling me 3 windows (@$600 each) Jim recommended his glazier Mark at M&J Glass. Mark replaced just the failed panes in 3 windows for $600 total. Jim saved me about $1200 by recommending the appropriate person to do the job. Now that's SERVICE! If I need to buy new windows, I know who I'm going to call! Thanks Jim.

If you need assistance with window installation this is the place to go. Jim is extremely professional and very knowledgeable. Although I was not able to start the house project today, I will be calling Windows Unlimited in the future.

Windows Unlimited is truly top notch. Jim and his team are extremely professional and dedicated to doing a quality job. We have done two window installation projects of significant scope with Windows Unlimited, in Spring of 2013 and Spring of 2014. In both cases the quality and craftsmanship were very high. Jim has the utmost integrity and was attentive and responsive to every detail. If all contractors provided this level of quality and service, home improvement projects would be much more pleasant to live through. I recommend WU unequivocally.

WU is a very good company. Jim is very knowledgable, responsive, and thorough. WU's window installation quality s very good, and Jim gives good advice as well, that helped me save some cost. I highly recommend them.

I've used Windows Unlimited recently on a small project of mine. I found Jim from Windows Unlimited extremely helpful, and he was not only able to get a window in the style and configuration that I wanted, and at a good price, but also worked with me to customize the glass so that it perfectly matched my garage door. When small problems arose with the installation Jim quickly and without hesitation sorted out the problems. I would highly recommend Windows Unlimited, and I am very likely to use them on future projects.

Windows Unlimited replaced most of our windows in our house and assisted with our kitchen remodel. The finished kitchen is amazing. And, the choice of windows is not only aesthetically pleasing but they are so efficient we had to turn the thermostat down 4 degrees throughout this last winter. I highly recommend window replacement for any older home.

The construction process was of course inconvenient but not any more than is to be expected. And, Jim was extremely responsive to all of my requests ( no matter how crazy) -- providing us with a finished product that was both professional and timely. It was a wonderful experience to work with a reliable contractor who clearly put our vision first and had the expertise to see it through. Now, if only I can find "Driveways Unlimited" so I can continue the home improvement.
