"Marvon's crew did an excellent job with renovations to the main floor of our 36 year old home. The work ethic his crew demonstrated was exception now days. They take pride in their work and truly want the customer to be happy with the end product. I would hire them again if I need this level of work done again."

"Ken is a skilled professional who is very respectful the homeowner and their property.  His work was very high quality, his price reasonable, and he was easy to work with.  I'm extremely pleased with the work Ken did and have already started my list of future projects.  Ken makes helpful suggestions, always cleans up before he goes home for the day, and is very knowledgeable about the kind of work he does.  I highly recommend Ken!!

"We would absolutely hire Kris again and would recommend contacting him for any project. We finished/remodeled our basement, and the KMK bid was among the most competitive that we received. The basement turned out even better than we expected. The craftsmanship on everything is excellent. Kris and all of his workers were professional, polite and hardworking. They finished on budget and on time. Further, they did a great job keeping the house clean and livable during the project (e.g., keep the Washer/Dryer hooked up while working around it). They even came out on an unexpectedly hot spring Sunday to reconnect the AC during electrical work!"

Basement Remodel FAQs, answered by experts

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.

Building a bar in the basement will likely add value to your home, although it’s unlikely that you’ll see a significant return on investment (ROI) unless you plan on using the space for you and your guests. If you think you’ll use the area frequently, though, it’s probably worth the investment, and you should see a bump in value if or when you sell your property.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.
