"When we started our plan of remodeling, the first thing we did was the complete roof replacement including kitchen vent & duct pipe installation to the roof, and new installation of attic ventilation. MMP did not only completed it just as agreed but also very efficiently. The crews were friendly, professional, and careful. The jobs were carefully managed and implemented effectively. I was impressed by Matt, who is the manager, and he does an outstanding job in managing the crews and the progress of the situation, and the communication was clear and always to the point. We then moved to initiate a search for a contractor of two bathrooms remodeling after completing the roof and attic vent, MMP was one of the many candidates. Matt has had not only the best idea and proposals but also shown an impressive & professional sense of evaluating the project accurately, including the possible structural modification as well as a competitive estimate of the cost of the build. His proposal included a rebuild of a wall of the bathroom to expand another one adjacent to it. Matt accepted to use my schematic design image (made with a software tool) and a spreadsheet list of the fixtures that I created - as many as fifty items including TOTO, Grohe, American Standard, Panasonic, and IKEA - to start the job (later changed some of them due to local plumbing code compliance) After beginning the bathroom remodel project, Matt shared what jobs will be done with us timely and efficiently via text so that we feel comfortable enough in knowing what is going on while living in the house of dust & noise from remodeling. The crews, Zen and Mark, were very courteous, extensively experienced, reliable, and friendly with excellent communication, sometimes with songs of 80s rock music. They ask me when more precise specifications are needed and notified me when they feel advance notifications are required. When a change is necessary due to inspection, they informed me and clarified what and why. I have never felt uncomfortable in living together with the remodel job which has lasted over four months. The completed two bathrooms were stunning, just as I imagined. Matt, Zen, and Mark have proved their strong & thoughtful expertise and lived up with my request patiently until completion. Great job. A home remodeling project cannot be successful without having a trusted partner, and my experience with MMP has led me to be glad to share my confidence that MMP has a credential to become your reliable partner to manage a construction project together."

"When you find a great contractor, don’t let them go. ;). I hired Tim to build a screen porch under my deck but added several projects as I recognized the high quality of work and attention to detail from his crew. In addition to the screen porch, they built a deck extension - so nice that I decided to have them replace the existing deck, installed a basement slider and replaced the door, installed a new fence and built a shed. Tim was responsive, open, honest and receptive of my requests and additions during the project. Great experience working with Tim and his crew: Dan, Brian, Eddie and Ben. Great job on all the work - I’ve received many compliments from neighbors and guests on the work you did! I can’t recommend Tim and his crew enough."

"We have been wanting to finish our basement for a very long time now but the prices we were given were too high! A friend of ours referred DCL to us and we thought we would give them a shot. The price was right so we started shortly after. They took care of all the paperwork and permits needed! Bob was there for the whole process discussing with us every step of the remodel! Very knowledgable and very well trained team! Our basement looks incredible and we enjoy spending time there! I would recommend DCL to anyone!!"

"I needed the backsplash in my kitchen done professionally since I chose tile, which is not something I could do. Torin fit my smaller project in , between his bigger outdoor projects. He was very professional, offered suggestions, did a great job, both installing and cleaning up each day so as not to disrupt my kitchen usage. His measurements and quantities were spot on( I was ordering the tile myself). I will definitely call him for my next project. His quote and finished price were almost spot on and very reasonable. I highly recommend him for anything you need done!"

Basement Remodel FAQs, 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.

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.

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.

Renovation enhances functionality, increases home value, and can add new space for personal or family needs. It typically modernizes older unfinished basements for new uses.

If you have the woodworking experience to build a bar from scratch and you have the time, DIYing the work is a no-brainer and can save a few thousand dollars. However, if you’re looking to include a sink, additional lighting fixtures, or high-end bar tops and cabinets, it’s usually a better idea to call in a pro. It will cost more, but the finished product will likely be worth it.
