Unlike other shops, Rick was here almost everyday
We hired Rick to remodel a small basement – a lot of companies are looking to remodel very large basements (over 60k). A lot of the cheaper contractors wanted to skip permits and do things fast/cheap. The problem is that if you don’t permit you can get into issues with declaring square footage.
Rick serves that middle ground. He is okay doing a sub 60k basement but will do everything right. We are in unincorporated Arapahoe county and boy are they a permitting nightmare. Rick navigated it like a pro and got us done faster than we expected.
Unlike other shops (I heard), Rick was here almost everyday and does a good 60% of the work himself. The egress window, electrical, and plumbing he had people he had vetted – but he was always here.
He also had a top notch egress window person – so that was helpful. Any additional charges or changes (I decided to move the restroom) he was clear up front. He kept to the quote and I never felt nickeled or dimed. I definitely would consider rick again for a remodel.

Delivered a great final product
Decided to hire RTP after obtaining multiple bids. They weren’t the lowest bid but were much less expensive than some of the large volume basement contractors. Finished product met my expectations for quality, was completed on time, and price did not change from the original estimate.
Rick was very good at communicating status and options and delivered a great final product. Our next door neighbor is now using RTP for their basement.

Rick came in at one of the most competitive prices
We could not have picked a more professional, skilled or courteous General Contractor. When we were interviewing contractors, we resolved to not just pick the cheapest quote but who would do the best job for a fair price.
Rick came in at one of the most competitive prices with a clear plan and timeline to finish the job. We hired Rick to finish our basement from scratch and he finished on time for the amount he quoted. He had access to our house throughout the day and managed the comings and goings of all contractors, as well as managed the complicated city of Denver permit process. He even added on small projects as he saw fit throughout the job at no additional cost.
We are thrilled at how the basement turned out, and we plan on using Rick again for future projects. I cannot recommend Rick enough for whatever job you are considering!

Rick did an incredible job to finish my basement
Glad we hired Rick to finish our basement through Home Advisor. Rick is very creative in design, knowledgeable, professional, responsive, courteous throughout the entire project. Rick did an incredible job to finish my basement also add a 1/2 bath in the first floor. The nice thing about Rick is he sends the status updates through pictures every 2 to 3 days from the start to end of the project.
