Reviews
Mammoth Construction did an outstanding job rebuilding my second story deck stairs. They handled everything from the plans and permits to the final construction, and communication was excellent throughout the entire project.
The experience was so positive that I hired Richard and his team again shortly afterward for interior painting and kitchen remodeling. They were professional, reliable, and delivered quality work on every project.
I would absolutely hire Mammoth Construction again and highly recommend them for decks, remodeling, and general home renovation projects.
We recently had our backyard pool and deck removed and new grass installed, and we couldn’t be happier with the experience. Communication was excellent from start to finish, the entire process was smooth and professional, and the final result completely transformed our backyard. The team was reliable, efficient, and easy to work with. Highly recommend!
