"Our original project was to finish up drywall work, painting and trim for two bathroom remodels. We decided to get quotes for inside doors along with it. Seeing that LM Coatings also does exterior painting and pressure washing, we decided to also get an outdoor quote for numerous pressure washing and painting of exterior doors and foundation. We were thinking of just doing the interior first and the exterior down the road, but decided to do all of it due to the fair price. Luis is very professional and knowledgeable. He was able to assess all of our projects quickly and give a thorough detailed quote. He and his crew are very polite and hardworking; even working all weekend in some cases. Although this project is named interior home paint, it obviously included drywall work, pressure washing many different things (including a metal roof) and exterior painting as well. We were pleased with everything, but he makes certain that you are satisfied before leaving. We were very impressed with his work ethic and willingness to please us. We will hire him again for sure and refer him to others too. Excellent on all!"

"I Hired this company to remodel my basement which was in bad shape. They sealed the floor and walls, put up 2x4 walls. insulation and drywall and painted everything. All new lighting, added a utility sink and partitioned off the furnace area and utility area. all new vinyl floors and doubled the living space in my house. The wife loves it and the kids now have a big play area. My wife now wants the bathrooms redone, I wouldn't hesitate to call them back in."

"Edward Perry did an outstanding job remodeling my bathroom, and I couldn’t be happier with the results. From start to finish, he was professional, reliable, and detail-oriented, making sure every aspect of the project was done right. His craftsmanship is excellent—the tile work is flawless, the fixtures were installed perfectly, and the entire space looks modern and refreshed. He kept the area clean during the process, communicated clearly, and stayed on schedule, which I really appreciated. I would highly recommend Edward to anyone looking for quality remodeling work."

"Overall, it was a good experience. AAA put down a vapor barrier and installed a Santa Fe dehumidifier with sump pump. The result is that we can now use the stand-up basement/crawlspace to store things under the house without ruining them. This is the part that you need to know. The installation was not without problems. First, they broke an A/C drain pipe, second, they cut a sprinkler controller wire while running a PVC pipe. Here's my take, accidents happen but how does the business respond to these issues? Well, Donna was very quick to send her team out to correct the problems and they even paid for the damage to the sprinkler system. To me, that's top notch customer service. Any business can make a mistake, but how they handle it is the mark of a good company. Every time I lift the roll door and go into the basement now, I'm amazed at how cool and fresh the air is down there. No more mildew and no more smell."

Basement Remodel FAQs, answered by experts

The time it takes to finish or remodel a basement can vary significantly, ranging from a few weeks to several months or even up to a year. On average, the construction phase can take four to eight weeks, but the total project time can extend to three or four months when including planning and permits. The timeline depends on several factors, including the basement's size, design complexity, the scope of the work, and your contractor's availability. A more detailed breakdown for an average-sized basement might include: framing (3-5 days), electrical and rough-in plumbing (3-5 days), drywall installation (5 days), flooring (2-3 days), and final touches like painting and trim (about a week). If preliminary work like installing a waterproofing system or addressing structural issues is needed, the timeline could extend to six to twelve months. Factors like difficult access, material transport, and ventilation needs can also add to the project's duration.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Home improvements that increase value offer a high return on investment (ROI) and can enhance your quality of life. Upgrades to your home’s curb appeal often add the most value, with garage door replacement having one of the best ROIs at 93%. Other high-value exterior projects include replacing your front door, upgrading siding and roofing, installing a stone veneer, adding new windows, and landscaping. For interior renovations, a fresh coat of paint provides an excellent ROI. Major projects like a kitchen remodel or upgrading appliances and HVAC systems also add significant value, as potential buyers appreciate the peace of mind that new equipment provides.

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.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.
