Our experience with the kitchen remodel was positive because the team was so organized with the project timeline. From the first consultation to the final evaluation everything was documented and explained clearly. There were no surprises regarding the budget and the team was very helpful with material selection. We are very satisfied with the results and the way they managed the entire renovation process.

We hired Cosmo Builders for some masonry work on our front porch and the team was very skilled. The consultation was helpful in choosing the right stone to match our existing brickwork. The installation was clean and they made sure the workspace didn't interfere with our daily routine too much. We are pleased with the professionalism of the crew and the quality of the final masonry results.

Working with Cosmo Builders on our home addition was a long process but the team kept us informed at every stage. We had a few concerns about the roofing transition but they addressed them immediately during a site walk-through. Their professionalism stood out compared to other contractors we have used in the past for smaller jobs. It was a smooth experience overall and the new room feels seamless with the house.

The team recently finished a siding replacement for us and the results have completely changed the look of our exterior. There was a small mix-up with the color of the trim initially but the team corrected it before the installation even started. Their professionalism during that minor setback really showed they care about customer satisfaction. It took about a week to complete and they kept the yard clear of nails and scraps.

We used Cosmo Builders for a full condo renovation and the team managed the logistics of the building very well. Scheduling the elevator and coordinating with the board can be a pain but they handled the paperwork and communication. The installation of the new cabinets and flooring looks high-end and the service was worth the investment. We appreciated the final walkthrough to ensure every small detail met our expectations.
