  • Seth and his team at DeMello Contractors were professional, timely, and their craftsmanship was top notch. I had a new roof put in on my garage and couldn’t be happier with how it came out. Seth went above and beyond to ensure I was satisfied with the final product and made sure to keep me informed of anything that came up along the way. Best part is they were in and out in a day.
