"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."

"Our small master bathroom was renovated by EUTR a few months ago. The planning and work went smoothly and the job was completed on time. The work area was kept clean at the end of each day. We saved a bit of money due to their ability to obtain comparable materials at a lower cost. We are very happy with the work done. Jay and Kim were great to work with. We would certainly consider hiring EUTR again for another home 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

While framing a basement is not as difficult as finishing a basement, it's something you should typically leave to the pros. That’s because if something is installed correctly, it will affect your entire basement. However, you can take care of some of the smaller tasks, like filling holes or putting up some insulation.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.

Yes, you can add a door to your basement—it might even be required, depending on building codes in your area and whether or not you’re using the basement as a bedroom. A basement contractor can give you some advice on installation and help you add a door to your basement.
