"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 are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.
