"I've got a 112 year old hose that is pretty solid, but it had a cracked floor joist and part of the flooring wasn't properly supported. I hired Kristian and his team to install a couple of lally columns to support a carrying beam and sister a couple of floor joists. Many contractors wouldn't even return my call because I wasn't looking to complete a huge remodel job, but Kristian came over, gave me a fair verbal estimate on the spot, and worked with me on timing to complete the project. Not only that, but the solution wasn't overly complicated. The job was straightforward, completed exactly as described in the time described, and there was no scope creep. If I ever have a larger need, they'll certainly be my first call. I would highly recommend K&X construction if you need any services that they offer."

"I called them and left a message about what I needed done. I received a call from them the same day. They were Abel to come the second day. The job of installing a gable vent on my house was done in less than 2 hours. I will definitely use them for my next project."

"I’m very pleased with the service and work I received from Timber Wolf contractors and his crew. He contacted me and arranged a time to look at the work I needed done. He promptly sent me a quote. He set up a time between our schedules to build my spiral staircase and replace a window with a vent. He arrived on time and completed the job beyond my satisfacon. I was so pleased with the results and communication I received, that I hired them to come to my other home to install "Flooring for my sunroom, pantry and hallway. They also painted trim and upgraded my hardware on my kitchen cabinets. I felt very comfortable with Timber and left him a key so I could go to work. I highly recommend Timber Wolf contractors for your home projects, they are professional, polite and hardworking. Respectfully, A. Saint"

Basement Remodel FAQs, answered by experts

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

Yes, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.
