"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."

"Response to my query was immediate. Husband and wife team, Gisele and Amir, came out to the house and wrote down all the things I needed done around the house. The jobs were many and varied and ranged from replacing basement windows, to creating backing for my lower kitchen Lazy Susans (so things don't fall off in oblivion), to staining a deck railing, to repainting basement and outside concrete walls, to reglazing and caulking windows, to creating a trap door for the plumbing, to sealing off/covering some dangling electrical wires, to patching a hole in an inside wall, and more. I got a full 4-page written quote ahead of time and was satisfied with it so I had them begin work right away. I left the house for a few days to go on a business trip and when I came back ALL of it was done and everything was cleaned up. There was only 1 thing that needed a bit more work and Amir came back and did this as soon as we could get it arranged. I liked their work ethic and professionalism so much that I have hired Gisele and her cleaning company to do my monthly housecleaning. We've had one cleaning so far and it was done well. Gisele speaks both English and Portuguese and will do translating when necessary for Amir and her cleaning staff. I am having fun learning some Portuguese words, too! They are delightful, easy to correspond with, up-to-date with technology (you can text and Venmo them), and I will continue to use their services."

"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"

"Ernest recently completed a basement remodel for our home. It went from a dark, uninviting spot to one of our favorite places in the house. The quality of work is fantastic as well as communication from Ernest regarding when and how things will be done. Ernest is currently working on two other projects in our house and we are already lining him up for more wood floor installs, paintings, and bathroom remodels. Highly recommend!"

Basement Remodel FAQs, answered by experts

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.

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.

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.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Efficient appliance positioning, optimizing existing plumbing, and sourcing energy-efficient materials reduce financial impact and increase sustainability.
