We love our new windows and look forward to working with A-Best again in the future! - **5/5 · Google Reviews · Pam Ela · 2026-08-27**: A Best Window replaced a single window for me. I had the go round from several other glass and window companies that either didn't show up or would only replace the broken pane or had a minimum of 5 windows to talk to me! The crew arrived on time, got the window installed, and left the area around t… - **5/5 · Google Reviews · Betsy Gervais · 2026-08-18**: Excellent installers. Very neat and precise. Covered the carpet and their shoes! - **5/5 · Google Reviews · Monique Nadeau · 2026-08-12**: We had our windows installed early summer. We have an older cabin and the windows were well worn and most of them did not stay up or close properly. From start to finish, A-Best Window employees did exactly what we needed and wanted. The new windows are well constructed and we love that we had a cho… - **Angi · Paul R. · 2024-03-01**: This company is the absolute worst experience I have ever had. The person who measured for my 12 window replacement estimate Lindsay, measured incorrectly. This caused the disaster from that point forward. When the installers came, the crew were unfriendly and appeared like they were hungover or on … - **Angi · Louis P. · 2022-05-01**: To be honest, I chose A-Best because the quote was very reasonable, significantly less than a quote by a competing vendor. Measuring and quote went smooth by a friendly, knowledgeable young lady. Because of covid, installment was delayed by a few months, but that was not the fault of A-Best...and de… - **Angi · Catherine D. · 2017-10-01**: From the initial estimate through installation, A-BEST was courteous and professional. The gentleman who came out for our consultation estimated that two sills would need to be replaced, and he built this into the quote. He was exactly right, and we didn't pay a penny more than we had been quoted - … - **Angi · unknownmaurice K. · 2015-12-01**:
My job was broken down into 3 phases. Phase #1, replacement of 8 windows in August, went well. The crew were polite, clean, took their time and we were pleased with the product....even if their trim work left a little to be desired.
Phase #2, replacement of 8 more windows in November, was… - **Angi · unknownclaire B. · 2013-06-01**: They were prompt in coming to give me the estimate. Their product was as good as I could get from a local store. Their price was good. They kept their appointment. There was something that had to be fixed but they came right back and fixed it. They probably had one of the best prices but I didn't ch… - **Angi · Nancy N. · 2013-05-01**: They sent someone to measure and they did that quickly. They put in the order and scheduled the appointment. They replaced the windows within a half a day. They were so quiet you could not even tell they were here. They were very professional and I was very pleased with the work. They cleaned up aft… --- Data freshness: last scanned 2026-10-04T07:43:34.698Z.
