Mannis Home Enhancement is a five star Home Repair and Remodeling company located in Boulder, Colorado. We are a family owned and operated business for over 97 years. We can fix it, build it, assemble it, clean it, remodel it, paint it, improve it, landscape it, insulate it, you name it, we can do it!

"DO NOT hire Mannis for your general contract needs. We made this horrible mistake, and it ended up costing us significantly. These other positive reviews seem to be from much smaller projects. I m almost certain our renovation was one of their first attempts at a larger project. Tyler has little to no experience in this field, and Mike (his dad/owner) was of no help. We hired Mannis to finish our basement. You name it, it went wrongmultiple crews in and out, creating disjointed work, chaos, and miserable outcomes. While the project was already running significantly over the original timeframe, and after we had advanced them (early!), the second deposit, Tyler took off to Thailand for 2 weeks. Upon his return, he called us immediately requesting more money, (before even the completion of the reciprocal work which should have been completed with the second deposit) and accused us of micro-managing the project, despite him not even visiting the work site, or addressing why the project had gone so off the rails. The project was eventually abandoned, and the incomplete work that WAS done was horrible: walls weren't straight, walls weren't floated properly, electrical was incomplete and dangerously unprotected, the wrong insulation was used throughout, plumbing had to be ripped out and redone, and trash was sealed up in the walls. We found out many things were not done to code, and it cost us a terrible amount of time and money to rectify."
