I had James Hardie siding placed and working with this company was a great experience. The team that came to my home to do the work were friendly, efficient and competent. Oswald, the project manager, was wonderful to work with and the experience wouldn't have been the same without him. He certainly knows his stuff and is a great advisor. He even went the extra mile to install Ring cameras and doorbell (which I purchased) for me as I was worried I would damage my new siding. I obtained three estimates and this was the most reasonable AND had the highest reviews. I'm not disappointed, and the final result looks so professional and nice! Have had lots of complements from my neighbors already. Working with contractors can SOMETIMES be a headache, but this experience was NOT and I HIGHLY recommend them!

We would highly recommend GS Exterior Experts and are thrilled with the work they did on our Hardie siding. Our project manager, Oswald, was extremely thorough every step of the way - between coming out to meet us personally at the start of the project, monitoring things during and assisting with punch list items after completion in a timely manner. We hope to use them again in the future.

Great siding and window installation. From the beginning to the end the entire process was easy, smooth, and beautiful. And the price was better than other quotes we got. Oswald, the lead installer, was fantastic. Nice guy, easy to talk with, and skilled. We strongly recommend them to anyone looking to do windows or siding on their house.
