"Premier is the best, and I love being able to recommend a company so confidently. Steve is hands on, exceeds expectations, offers great cost conscious recommendations about where to spend and where to save and delivers high quality work. His team is similarly dependable and very competent. I used Premier to replace the windows on my 1920's cottage back in 2018, and then hired him again to reside my home just a few weeks ago. He beat his own timeline and his price was as good or better than all of the three other companies from which I got quotes. Highly recommend!"

"The person that came to our home for the quote was friendly and knowledgeable. We were going to have 4 windows fixed with new glass inserts. After his inspection, he suggested to do 2 windows. He was honest and a pleasure to deal with. He was the installer as well and did an outstanding job with the glass replacements. He cleaned up the entire work area before he left and you couldnâ t even tell he had been here. We really appreciate his concern for our home and property. The office team even followed up with a call to see if we had any questions and if we were happy with the work. We canâ t recommend this company enough. We are completely satisfied with their work and customer service."

"It went very well Gus explained everything from process, how long it would take and pricing. Once the windows arrived they did the job in 1 day very quickly. Love the new windows and for sure I will call again to complete another project in our home. Great work done. From: Leo & Rosy"

"I highly recommend Windo-Well Cover Co. They were here when they said they would be, came prepared do the job even if it rained, and went above and beyond by cleaning out the window well before installing the cover. I am happy with the look of the cover, but am especially pleased with the strenth and durability of the cover. We will use them again to cover additional window wells."
