Best SGS Inc. is rated 5.0 out of 5 by 21.
Rated 5 out of 5 by from Very pleased with the results ! This was my first time ever dealing with the world of windows. All I knew was I needed replacement windows soon. Devin was fantastic in explaining everything and keeping in touch with me during the whole process. I enjoyed dealing with everyone in the office and found them to be very professional and yet personable. Also enjoyed the install crew when they came out. My windows look great and you can tell they are quality made. Thanks again...

Rated 5 out of 5 by from Professional Start to Finish It was a refreshing change to have a company from start to finish exhibit excellent customer service, great product, a very fair price and a care for the quality of their work at our home. I would highly recommend them. Devin knows his business well and was the sole reason why we went with them. Chris the owner was professional and has a company to be proud of.

Rated 5 out of 5 by from Fast, helpful and professional! I'm new to the area and found Milgard close by. I called and it wasn't long before I had a rep at my house helping me decide which windows would be best for my new home. Devin was very professional and quickly had his team installing my new windows!! Very thankful and impressed with the service.

Rated 5 out of 5 by from A great install once again Have been working with Best Windows since they opened their doors. While we don't have a lot of work for them, what we have had has been handled in a 100% professional manner and the install work has all been top notch. Just recently had an install that needed to be done before the Christmas holidays and even with our client's indecision as to schedule, Best Windows were able to pull off the deadline. Great job, great crew, great office staff.

Rated 5 out of 5 by from Best Windows was absolutely the BEST choice! Replacing windows on a home our size was a huge investment and with so many firms to choose from we needed to insure we chose wisely. We had been referred to Best by a couple of the local contractors; hiring them was the 'best' decision we ever made! From start to finish their attention to detail was above and beyond. Devin, who initiated the process, was on top of it. Hugo, the site project manager, was incredible. He made a point to reach out to introduce himself and to let us know he would be on-site throughout the project. He added finish detail that was incredible. I could no doubt offer so much more to this review, but I'll end with - If you're shopping for new windows, save yourself some time and trust that Best Windows will be your 'best' choice! Thank you for making this part of our project so painless! Lisa Humphrey

Rated 5 out of 5 by from Great Experience Overall ! We needed to replace the windows and shower door in about half our house. From the first time Mike came out to talk to us about our options, we were extremely impressed. We got competitive bids, and found Crestline to be the best in service and competitive in pricing. Throughout the process of bidding, selection, scheduling, and installation, their work was top notch. We couldn't be happier with the quality of the product, the work, and the character and professionalism of the office and field staff. Thank you!!

Rated 5 out of 5 by from FANTASTIC SERVICE!!! Hugo and his crew arrived on time and installed 14 Tuscany Milgard Windows, and did a perfect job of installing and creating new borders. He kept me informed of what was happening at all time, and at the end of the job did all clean up. I highly recommend BEST WINDOWS to all!!!

Rated 5 out of 5 by from Outstanding...... Bought 14 windows and a door from Best Windows and Doors. Great value and great service from start (initial sale - they were one of 3 bids), through installation. The installation team of 5 did an outstanding job of removal, installation, doing custom trim, and cleanup. We were very impressed with the teamwork of the installation crew and would recommended Best and their team to anyone.
