"I would highly recommend MMP Construction. Matt and his team are knowledgeable, friendly, and extremely hardworking. Even after running into some unexpected structural issues once the walls were opened up they still managed to get the job done in the time frame quoted by working extra hours and weekends. I was truly blown away by the level of dedication and service. Anytime a challenge came up, someone on the team was quick to provide a great solution. And the finished product is absolutely gorgeous. I would hire them again in a heartbeat.

"Peter has great attention to detail and is extremely meticulous with his work. I felt that Peter went above and beyond with our deck remodel project. He was very consultative with the material selection and provided options and suggestions that most contractors would have overlooked. I highly recommend him and plan on using him again for future projects."

"We worked with Timothy Petrides who was absolutely amazing. Tim was so helpful and responsive and helped us design a beautiful new Trex deck and stone patio. We also had an egress window installed in our basement, railings put in on our front steps and the siding on our house replaced. We were so pleased with the timeliness, quality and attention to detail on all of the projects. Everyone we dealt with from the owners to the contractors were so friendly, hardworking and professional. We will definitely be using RORHI for any future renovation projects."

Basement Remodel FAQs, answered by experts

Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms. 

Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.

Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.

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.

The average cost to remodel a basement is between $12,100 and $33,400. Depending on the project's complexity, the price can be as low as $3,500 or exceed $50,200. For a simple project like adding a home office, you might spend between $500 and $3,000. However, a more extensive project, such as adding a bathroom, can range from $6,600 to $16,500. The final cost is influenced by factors like the basement's size and condition, the type of remodel, material choices, your location, and accessibility. For an accurate price, it's best to consult with a basement remodeling team.

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.

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.
