Excellent experience. I wasn't able to be here when the patio door was put in, and I didn't even know the men were here, except for my new doors being installed. They didn't leave a mess inside or out. I also have a cat, and they put her in a different room so she wouldn't get out and let her back out when they left. It's nice to know you can trust a company to do the job right without watching them. Highly recommend.

We used SK Windows and Doors for hail damage replacement of gutters and vinyl siding, and decided it was time to replace all the custom windows in our ranch home as well as the soffits and facia and downspouts. It was quite a large project. From start to finish, the communication was great. Lloyd met with my husband and me to help decide colors, types of siding, choosing trim, choosing from different brands, and also helping us choose the style of windows---we chose to keep some transoms and get rid of others, and chose to put some differently-styled windows in other places. The team also trouble-shot a certain area in my kitchen and dining room where there was an area they were concerned about possibly having to cut into the granite counters and ledges. Instead, they built out the casings perfectly with no damage at all! There were a few hurdles and they worked around all of them, even added in some other custom wrapping work, and still stayed on budget. Our home now looks brand new! I couldn't be happier with it, and I

 We could not be happier with the work that SK Windows and Doors did for us. Right from the first phone call, we were impressed by their estimate process and then to the final installation and clean up. We had really good things from others about S&K so that helped in asking for an estimate. Their pricing was fair and right to the point. They gave recommendations and helped with the entire process. I can't believe how well they cleaned up after installation. You would never know that they had been here. I can't recommend them strongly enough!!! This is definitely the place to go to. Thank you for our beautiful new windows and back door.

As a business owner for over 40 years, I've ran into many different types of people... And I have to say doing business with SK Windows & Doors was one of the best experiences I've ever had. Lloyd and his business partner are some of the most honorable and trustworthy people I've ever had the pleasure of doing business with. I would highly recommend anyone to do business with SK Windows & Doors.

Shawn from SK arrived 2 minutes before the scheduled time for our estimate. He was very friendly, informative and not pushy in the least. He explained our options, prices, etc. He gave us an estimated arrival time for the windows we ordered and they arrived 2 weeks ahead of time. We scheduled the installation and they were right on time, efficient and professional in their installation, and cleaned up everything. We are so pleased, and we love our new windows. It couldn't have gone smoother. Thanks, Shawn and SK!
