What our customers say.

My experience with Grellis construction went much better than expected! They orginially told me it would take 3 weeks to complete my project, but they were able to complete my skylight installation and roof repair in one day!

Grellis Construction provided courteous and professional sales staff. They took the time to explain all of the options and availability. Once an agreement was made and the contract was signed the process was very smooth. They installed the roof in a matter of days (in-between bad weather conditions) in a timely and efficient manner. The Forman was very knowledgeable and took the time to answer my questions and corrected some minor issues. There were a couple of things that were brought up at the walk through, but were addressed and corrected in a timely fashion.

I would recommend Grellis Construction to my family as a contractor that you can trust and that follows through.

I spoke with a lot of contractors before I made a decision to go with Grellis Construction. As a single mom, I was a little scared about a contractor ripping me off and leaving an incomplete job. The professionalism that they exhibited was unmatched by companies like Sears, Long Fence and Thompson Creek. The sales rep came to my house and provided a no-pressure free estimate. He also set-up a realistic ┬áschedule of each phase of my window, siding and hardwood floor installation. The job went so smoothly that I couldn’t believe it. I’ve dealt with a lot of other companies in the past but now I don’t.

I didn’t have a lot of experience with home remodelling and was a little worried that I was getting in over my head. However, a designer from Grellis Construction ┬á walked me through the whole process and explained my project to where a 6 year old could understand it. I got a great deal, and most importantly, quality work. They have done work for me and my kids. They completely changed the way I feel about my home.
