I just needed to replace one window and their price range was in the middle from 4 different quotes so not expensive but not cheap either.

Barry understood our needs, the price was less than some of the other competitors but not so much that I worried about quality. From ordering the custom door to the date of install was only a couple of weeks. On the date of install, Nick arrived early and got right to work. The door was installed, looks great and Nick did a great job of cleaning up. I had a question about the door the next day and Barry came out and cleared up that question in minutes. We will definitely use thermalcraft in the future!

Looking at my phone, I see their called was marked as potential spam, which I never pick up on these types of calls. Talked to the owner who said it was their policy not to show up for an appointment if it isn't confirmed. I asked what they are confirming and the owner said it was the address and what service I needed. I had rebooked for next Monday and even though I told the guy the address and service required (what is why they have to confirm) he said I still needed to answer their confirmation call on Saturday or Monday. I understand why there are so many 1-star reviews. The owner goes out of his way to not wanting to do business with customers. Steer clear of this business.

We recently had all of our windows redone with new Marvin double-hung, custom built to match the…read morelook of our century-old house and optimized to reduce exterior noise as much as possible (cars and planes). Robert in particular did a phenomenal job working very closely with us and even went above and beyond catching some inconsistencies in our initial estimates from the manufacturer, ensuring that everything met our exact needs. We got quotes from quite a number of the local contractors, but none were as relaxed and supportive as him. It was the exact opposite of pushy. On top of all that, the quote was solidly competitive and the installation was extremely well done. Every old house is unique and the crew did a terrific job on ours, both with the removal of the old windows and the installation of the new. Our neighbors can't seem to stop complementing how good they look, and how perfectly they match the character and appearance of the originals! We cannot recommend them highly enough.

We liked the communication and informative approach that this one provided, without being pushy to get us into windows we didn't need. Everything was presented clearly and the representative really knew so much about his window selection and about others. The window installation was right on schedule and it went very well. We are so glad we chose this window company and we would do it again.

Bought a front door and sliding glass door several years ago. Both were good. Last October it was…read morehard to push the sliding glass door. A rep from Dilworth came out and put new rollers on the bottom of the door. It worked good until the next day when it didn't. I called the company and told them about it. My handyman was out a couple of days latter and I told him about the door. He went outside and opened a latch and put a screwdriver in and turned it a little. The height of the rollers were adjusted and the door slid perfectly. I called Dilworth and told them about that. I told them I didn't need new rollers. I just needed the door to be adjusted. They said someone would call me back. I called several times and they always had a lot of excuses. Nothing was done. I paid $480 for nothing.

She was pleasant at first then called me back and told me her worker said he was told by the gentleman here that they did not have to worry about there mess he would take care of it, he didn't want them on his property... 1st off there was no man here ( no one was home at all...) 2nd one of the guys was already on the property picking up the big pieces of trash they let go. She said well he did run his magnet over your driveway, There's NO possible way he did with all the nails that were left and we also have 3 cameras that face our driveway 1 points straight down it one across it and the other the front and the only time it picked anyone up was when he was here picking up the big mess! She did tell me they would be here the next morning between 7-8 am I am still waiting for them but when I called her to ask if there was an eta she blew up on me, was Cussing me out and Hung up on me, Again this was all caught on camera, when I told her I am leaving a review. I have been NOTHING but nice and understanding of them... THIS IS NOT EVEN A COMPANY THAT WAS DOING ANY WORK FOR US BUT A NEIGHBOR!!

John and his team were top notch. We dealt with this in October 2018 and had our windows for about…read moresix months. Our home required about 26 windows including double hung, picture, and sliders. John met me at my home in the late evening and provided a quote. There's no sales pitch, used car salesman tactics, demonstrations that have little real-world results, etc. With other Window companies, they push their "Cadillac" windows that give a marginal performance increase for an exponential cost. Not with Best Windows. I knew beforehand they installed Kensington brand windows. They started with the manufacturer's basic line. I inquired about the mid-level line and John provided his input on why he didn't think they were really worth the additional investment. John's pricing was straightforward. There was no "oh you get a Yelp discount" or "oops I forgot to add a window to your quote, I'll throw that in for free." It was refreshing to talk to a non-pushy company for once. We went with John and his installer Chris put them in our home about six weeks later. Took about a day and a half. His crew showed up about an hour earlier and were super fast! The windows are awesome and have already saved on my heating bill this past winter.

Some of our neighbors got all their windows replaced by this specific location and had a very positive experience, so we got an estimate from one of their sales associates Harley Perry for 20+ windows. Harley was great to work with, very personal and answered all of our questions regarding the quality, warranty, and installation process. The cost can't be beat and the level of customer service has been exceptional. The install was very smooth and took a full day to do all windows in our home. We encountered a couple small issues a few weeks after, but Voytek and Ivana were responsive and made sure every issue was addressed. Joel and Jackie run one of the best window installation businesses in the area, if not the best in terms of service, quality and price. I would highly recommend them if you're looking to replace your windows or just looking for a fresh upgrade. Thank you and happy holidays! Best, Charlie
