"My wife and I needed to finish our basement to accommodate our growing kids. We had an excellent experience with Everything Under The Roof. They really listened to what we wanted to build and everything was done well, on-time, and on-budget. One thing I particularly appreciated is that the owner was onsite doing the work, and not simply sending a team of workers. We'll definitely be using Everything Under The Roof for any future projects."

"The work was done in a timely manner, and as I was told we needed to wait to paint the stairs, and that was the last item, i paid in full. It has now been over a year and i keep requesting that they come out and complete the work, and i receive no response. Disappointed."

Basement Remodel FAQs, answered by experts

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.

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.

Key trends include home gyms, theatre rooms, additional rooms (bedroom/office), and more, with personalized styles reflecting individual preferences.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.
