"We give Bel Island Five Stars for our house siding project with Hardy plank siding and Maibac shingles. When Andrei and his crew came to our house, they removed our old painted curling shakes and replaced them with beautiful Cape Cod grey Hardy plank siding on the front of the house, and Maibec shakes on the gables and kitchen entry way, with white Azak trim all around in less than a week. They replaced two windows with Harvey windows as well. The entire crew was respectful and tidy at the end of each day and cleaned up at the end of the job like they were not even there. The best thing was the price. Get three estimates, you will be shocked at Andrei's price. We got 4 prices and the closest to Andrei's was $15,000 more than his quote which he stuck to."

He is super and he has a person who helps him with the installation and removal of two units. He always reaches out to schedule time to do this for me and he always notifies me of his arrival time. He is professional, polite, efficient and caring."

"Nick did a wonderful job repairing the siding on our garage. He completed the work promptly, and his rates were very fair. He stayed in communication with us as we were waiting for a replacement window to arrive. We will definitely call him again the next time that we need some carpentry work. Thank you so much!"
