We help homeowners find solutions to home remodeling and construction renovation needs. We have been serving the Denver, Westminster and Arvada communities for over 25 years with the highest attention to detail with our master design concepts. References are available and we pride ourselves on working around your schedule, respecting your privacy and property. We thank you in advance for allowing us to give your home the attention it deserves. As always we provide a FREE initial consultation, then follow up schematic drawings, preliminary budgets, and as-needed 3D renderings to help you make a great decision for your families needs.

"Kelle is a good salesman. Unfortunately that's where the good ends. Today Kelle "terminated" our basement remodel agreement because they were "overbudget and have another project to focus on." We have thousands of dollars of work remaining and he "forfeited" $700 of punchlist left to bill - big mistake on our part. Not only that, but he scammed us out of a $1,500 Facebook promotion to take photos of the project upon completion - since its not "complete" we won't be seeing that credit. There is good news - we can now finish the work to a level of quality that is acceptable - we have fought Kelle every step of the way to prevent them from cutting corners which they describe as "industry standard." If you care about the quality of your project, look elsewhere so you don't end up making the same costly mistake as us - we've worked with many contractors and never experienced anything like this. We hired Kelle because we have a new infant and trusted someone would get the project done."

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 wrong…multiple 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. "

FAQs for addition to existing structure building service projects in Black Hawk, CO

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite. 

An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
