"Brad was one of the best people to do business with: not high-pressure at all, very easy going, professional, good workmanship, patiently answered all our questions, and gave us a reasonable price for our three windows. They were only just installed on Feb. 6, '20, so it may be too soon to evaluate their quality, but they seem to be installed well and look well-made for mid-price windows. Brad's clean-up of the work sites was very thorough, as well. We are very pleased with Brad and All-Type Window and Door LLC and would definitely use them again!"

"My new windows look great! Very professional to deal with, work was done on time and for a fair price. Would recommend to anyone looking for replacement windows!"

"Great experience with this company! They replaced a window pane for us…the seal had broken down. They communicated well, were professional, and did a great job. I will use this company again"

"Fantastic! Quality work for reasonable cost. Would definitely and highly recommend for handyman services."

"Alex Faires was a fantastic project manager. We had extensive hail damage and had to replace our entire roof, siding and gutters. Alex is knowledgeable and took the time to answer all of our questions. Alex was very responsive and kept us informed on scheduling and material deliveries every step of the way. H&F handled everything directly with our insurance, making the process seamless and hassle free. Alex coordinated multiple crews to minimize the disruption and all of the work was completed ahead of schedule! We are very happy with the results and highly recommend Alex and H&F!!"

"This professional team completed several projects for me in the last few years. Projects include the removal and replacement of 17 doors and all baseboards in the entire house; replacement of a custom-made oval window; stair banister replacement and renovation of the existing newel posts and handrails. Current project includes kitchen remodeling including cabinets, counter tops, and backsplash replacements. Their team has a real attention to detail which was evident during the design phase, throughout the installation and even in the cleanup. They are very easy to work with, very responsive to emails and calls and they aim to please. They produce high-quality work and provide good customer service. I would recommend this company in a heartbeat."

"Renewal by Andersen of Wyoming did an incredible job with installing windows in our home. Thank you to the team who did the install and to the company for creating these exceptional windows."
