"It went extremely well. Being female, many contractors gave me obscenely high quotes and didn't detail out prices (which I requested). Working with John at Best Windows was such a pleasure. He listened to my needs, was candid, honest, and detailed out pricing. Also, he provides the highest quality service for the best price. His team (pleasant & professional) Installed 14 windows. I expected minor issues. And John/team were quick to respond and fixed them immediately. I highly, highly recommend Best Windows."

"We used Integrity Windows and Siding back in 2012 to replace our siding and half of our windows (one of the windows did break shortly after installation - it was quickly replaced at no cost, no questions asked). Fast forward to 2023, we again sought out Integrity and Howard to install some of the remaining windows. Howard is very knowledgeable, easy to work with, explains options, kept us informed during the process and sells a quality window at a fair price. Mike, who has been with Integrity for 20+ years, was very careful during the installation - clearly he knows what he is doing! The windows look great, work great and keep us warmer. We highly recommend Integrity and Howard for your next project. We couldn't be happier."

"I changed the 11 window glass. The price is not cheap but the job is good. they are very professional, that is why I like them."

"This pair of true craftsmen worked magic on my old but serviceable 28-year-old wood windows. Two casement & two large fixed windows suffered substantial cosmetic rot in sash, sill &/or brick-mold. Windows were removed & completely rebuilt. The skill displayed in fashioning the intricate re-framing of the windows from 4â x4â stock using a table saw amazed me. They did additional exterior work, replacing rotted wood trim around the garage & chimney areas. All work was caulked, & repainted. Half dozen other contractors shied away from any cosmetic repair, each suggesting full window replacement. Work was done very reasonably compared to replacement cost, they look brand new. I thank God they came to DeKalb for us & saved our beautiful windows. Prayers answered, they have our highest recommendation."

"Closed stuck windows. Now OK as long as these windows are not opened. Offered service to replace hardware on window for $150 per window. Decided not to do anything."
