"I had a great experience working with this roofing company. From start to finish, the team was professional, organized, and efficient. The quality of the work definitely met my expectations, and I was impressed with how quickly they completed the entire reroofing project without cutting any corners. Communication was clear throughout the process, and they kept me updated on each step, which I really appreciated. There was a small delay in the delivery of some materials (not their fault), but they handled it quickly and kept things moving. If you’re looking for reliable and quality roofing work, I would definitely recommend them. It’s refreshing to see a company that values both speed and quality without trying to endlessly price gouge me — (had to deal with a few others before I found them :\)"

"Ovation Restoration did an excellent job with our home improvement project. In our master bedroom, to take advantage of a fantastic view, they removed a large window from one wall, sealing it up like new, and installed a similar window on another wall. The work was performed quickly and skillfully, with great results. They also turned the double door leading into that room into a single door, creating more space in the room. Concurrently, in the guest bathroom, the old tub was removed, and a beautiful walk-in tiled shower was installed, along with a window with a fantastic view. The project manager Rick was a pleasure to work with, and his team were all professional, conscientious, and friendly. Everything turned out just as we imagined. We would highly recommend Ovation Restoration."

"Working with Puffin was incredible. What originally started with a small repair became much larger when we began demolishing portions of our house that had fallen into disrepair and Kristian and his team were there every step of the way. From communicating changes and keeping us up to date on expenses and needed repairs to educating us on code compliance and inspection schedules we felt safe in Puffinâ s hands. Our home is now safe, strong and beautiful because of Puffinâ s hard work and dedication. I would happily work with them again."

Basement Remodel questions, answered by experts

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.

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.

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.
