This company eased every fear I had. The owner was very professional and answered every question I had. The staff equally as helpful. The workers knocked the work out quickly and cleaned up after themselves. I love my new roof.

Used this amazing company to turn 3 windows into a big customized door to my backyard and I was beyond impressed. They workers were courteous and on time. Work was completed within the amount of time scheduled and even came back out to fix some minor blemishes. Would highly recommend.

Let me first say I was unsure of Grellis construction cause I had never dealt with them before. They amazed me and knocked out my job quickly. They communicated with me every step of the way and their installer was very quick. Will definitely use them again

I can say this they have patience of steal. Due to past bad experiences I was very nervous about using Grellis Construction. I am happy to say that they were simply amazing. I got an amazing deal and the workers didn't leave till I was full satisfied. Thank you guys again

Amazing experience and very affordable. My work was done the same and the craftsmanship was so well done you couldn't even tell where the damage was. I would recommend them to my neighbors and friends looking to have work done.
