"Hired Greg for a full gut and remodel of a bathroom. Greg was very competent, personable, and took the time to understand exactly what we wanted. He made us feel like we were in good hands. He took the time to make sure things were done the right way. The result was top notch, couldn't have asked for more. I would definitely use this company again!"

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"Jose and his team were the best team I have ever had work on a job in my house. Jose went WAY above and beyond to make sure we had our basement back in order in a timely fashion. He was willing to work after hours if needed to help get our finished basement back after we had suffered a sewage leak and had to wait until mitigation was complete. A 3-4 day job was complete in 2 days! And one of his workers, Carlos, from the second day stuck around to help me get the heavy and large items back into the basement. There was a previous review that said Jose was very emphatic to their needs and that is so true. That review actual was what made me give Jose a call. I wish there was a word better than highly recommend. Thank you Jose and your entire team!"

"I had a great experience with the Exterior team company. Ronald was very punctual in the initial visit for an estimate. I explained to him that I could not be there and he scheduled another time the same day to return to discuss the estimate. He was on time that evening as well. He was very fairly priced. We scheduled the job a month out. He had all materials delivered the morning of and the crew was on site by 7 30. They worked hard throughout the day and as a thunderstorm was coming, they worked tirelessly to cover the remainder of the roof. They returned the next day, completed the job and cleaned up. The roof is looking great. I would highly recommend Ronald and his crew."

Basement Remodel questions, answered by experts

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.

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

You should always use high-quality lumber for your framing in order to ensure it will last the test of time and resist moisture. Use 2-foot by 4-foot lumber that is pressure-treated for your framing.
