"Our roof was in bad shape and we needed to have it replaced. I had gotten estimates and decided to go with Home Pro Remodeling. Emil and Brian were our contact people for the project. Emil was very professional and paid attention to our concerns. He worked with us through the entire project to our complete satisfaction. Brian is extremely courteous and helpful as well! The project went very smoothly, was completed before the initial project end date, and the results were beyond our expectations. The job turned our beautifully! Our new roof looks FANTASTIC! Our neighbors have commented to us how great it looks. We are very pleased with our experience with Home Pro Remodeling and would definitely recommend them."

"True Vine was amazing from start to finish. They handled construction work at my home that was fully covered by insurance, and the entire process was smooth and stress-free. The workers were incredibly professional, friendly, and respectful of my home. They showed up on time, communicated clearly, and made sure everything was done right. The quality of the work was excellent, and the project was completed within the promised timeframe, which I truly appreciated. I highly recommend True Vine to anyone who needs remodeling, insurance-related work, or add-ons. They are reliable, efficient, and genuinely care about their customers. I’m very happy with the results!"

"Progressive Builders is hands down the best contractors company we've ever worked with. Eric is professional, timely, hardworking and above all honest and fair almost to a fault. He does all major renovation and construction work on my properties and recently completed a significant gut remodel and addition to one of our houses . He is great and understands the entire construction process including permitting and working with the planning department to get everything signed off. Even better, his prices are fair and reasonable."

Basement Remodel questions, answered by experts

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

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.

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.

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.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.
