Matthew completed a kitchen remodel for us and we are thrilled with the outcome! He has an incredible eye for detail and design as well as a phenomenal knowledge of the construction process. Matthew is very easy to communicate with and is always willing to talk things through and do anything he can to make the end result exactly what you want. He is very professional in his work, however never makes you feel anything less than a friend. We greatly appreciate what he has done for us and will definitely use him on our next project!

We appreciated the honesty and attention to detail that we got from Firmus. Matt was upfront with us about our renovation and wanted to get it right the first time. He approached the finishing touches as if it were his own home. The value and attention we received were far beyond what other contractors could offer. We continue to recommend him!

We had many contractors over the years bid our
kitchen renovation. We decided to go with Firmus based upon Matthew’s vision and professionalism. He was the first contractor to walk in and figure out what needed to be done. We were not excited about living in our home throughout the project. 1930’s kitchen with plaster walls are a nightmare to gut. Amazingly, the house was tidy every day. Matthew is creative, honest, very hardworking, adaptive and overall just a friendly person. Firmus reflects all of Matthews great qualities! Our kitchen is now the center of weekly social gatherings. Our friends always look forward to coming over to hang out in the awesome space Firmus created. Thanks Firmus!

My wife and I had a complete bathroom overall done by Firmus Contracting Solutions and were greatly impressed with the quality and affordability of their work. We are very happy with the results. In addition to our bathroom remodel Matt found and fixed a leak in our bedroom window. He was able to remedy the leak that would have cost us thousands of dollars in repairs had we let it go on. His awareness and fix of this problem is greatly appreciated!

I have wanted a new, updated kitchen for so many years. Ours was an old 1950/60’s style of kitchen, with the old metal cabinets, old white porcelain sink, etc. After talking to Matthew he made us feel like a lot could be done in our budget range. He even found things that needed fixing that we weren’t aware of like a sinking floor. They began gutting the whole kitchen & I was amazed to see the skeleton of that old kitchen looked like the inside of an old ship. That’s when the magic started. We watched as each step took place: the wiring, the insulation, drywall, windows, lighting & cabinets. The wonderful cabinets where I have plenty of room to put things! No more setting things on the counter or under the table, etc. Matthew answered any and all questions we had as it went along. He and his crew began to feel like part of the family. We couldn’t ask for more friendly, easy to talk to people to work on our new kitchen. Not only that but very trustworthy people... each and every one. Now I spend more time in my kitchen and love cooking again...and I find myself staring out my new windows at the pretty view. I love showing it off - everyone knows that I love my new kitchen. Thank you Matthew & crew!

We hired Firmus Construction to enclose a front sitting room in our house with French doors. We were very happy with the outcome. In fact, if we didn’t know any better, we would believe that the French doors were original to the house. We will be
recommending Firmus Construction to all our family and friends.

The work FIRMUS has done on our kitchen has
unbelievably transformed our home and living space. Matt and his team completely gutted our kitchen down to the studs including vaulting our ceiling while making the new kitchen look and feel
as though it always went with our home. Their attention to detail is next to none.”
— Kraig from St. Peter's
After working with several different companies both personally and professionally, Firmus LLC is by far the most diligent and hard working company out there. Their attention to detail was paramount, and persistence to stay on schedule was incredible. I would recommend them to any and everyone (and do!).
— Marc from St. Charles
Firmus put up the two walls for my new office in the basement. They installed new lighting and connected my HVAC system. They handled all permits and scheduling all the different contractors.
Additionally they installed the huge replacement
front windows. Everything was on time and they did
an excellent job following up to make sure everything was perfect.

I am so happy with the work that Firmus did for me. We completely remodeled our kitchen and went from a tired 1980s look to a completely modern and beautiful style. The guys did excellent work and I couldn’t be happier with the result!! I will definitely use them again when it’s time to remodel the second floor of the house!
