"Great results from waterproofing. Turned my spring flooding anxiety to calm. As humidity rose in summer, I put in a small dehumidifier. Made basement noisy as it struggled to dry and produced a lot of heat. As temperatures rose to about 83 down there and the humidity rose to over 68%, I had same people put in a whole basement commercial-grade dehumidifier. The small unit dropped the humidity to around 50% in less than an hour. Incredible performance and have me peace of mind and peace and quiet downstairs. Temperature dropped gas as well. Weel worth the price to save my most expensive investment."

"These guys were great! We got turned down by two large companies because our dryer vent was almost at the peak of our roof on the second floor, but these guys took it on. They came out the same day we spoke with them to take a look and draw up a quote and then came back the following day to do the cleaning on our dryer vent and put in a new vent on the house. The previous owners had on the wrong cover which caused most of our issues to begin with. I would recommend them to anyone we know. They were professional and explained out everything."

"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

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

You can paint your ceiling or install a drywall ceiling if the ceiling is unfinished, as they take up less headroom than drop ceilings. 

If there are pipes in the way of ceiling installation, you can do one of two things: reroute the pipes or adjust the installation to fit, which will cost extra.
