"QUICK, FRIENDLY, and CHEAP!! First, AJ called me within 30 seconds of me texting him asking for an estimate. I sent him a photo of our water leak issue and he immediately responded. He actually explained that we could probably handle the repair ourselves if we were up for it, instead of paying him or someone else. He then walked us through every step in detail and made sure we were comfortable with the directions. So in the end, it cost us $0 in labor and only a small amount for materials, and really demonstrated AJ's integrity and generosity!"

*Authorized Waypoint Cabinetry Dealer* dRemodeling is Philadelphia's HIGHEST-rated home improvement company. We've been recognized by Remodeling Magazine’s Big 50 for best remodeling companies in the country. We were named Contractor of the Year in 2017 by the National Association of the Remodeling Industry (NARI). We have also won Angie's List Super Service award 8 years in a row in addition to having won Best of Houzz in both Design and Services 3 years running. We are a one-stop shop for kitchen, and bathroom remodeling projects. From award-winning interior designers and amazing in-home technicians, to a complete Showroom and Design Center (carrying top-industry brands for kitchen cabinets, vanities, tiles, natural stone, hardwood floors, plumbing fixtures, quartz, marble, and granite countertops) dRemodeling is your ideal home remodeling solution. We'll take the stress out of remodeling and help you save time and money. Our inspired interior designers and our skilled installation team will work with you from design conception through completion. We handle everything for you, all under one roof. To top it all off, dRemodeling offers a 5-YEAR warranty on labor and materials when you hire us for our full design, material procurement, and construction services. The dRemodeling Team includes real people with inspired solutions who are motivated to make your remodeling dreams come true! We look forward to getting to know you and your project! Happy Remodeling! Feel free to call our direct number 215.848.4444 and mention that you are an Angie's List member.
"We feel very fortunate to have found and been able to work with dRemodeling to renovate our kitchen and 2 bathrooms. Throughout the process we have been struck by the craftsmanship, attention to detail, excellent level of communication and clear desire to make us happy (“we just want to see you smile”) that we have experienced. All of the other 5 star reviews have aptly captured the experience that we did, so I will not go into as great detail as I normally would. The design process was easy – our designer asked pertinent questions that helped us hone our visions and thoughts into reality. We felt seen and heard, in terms of defining our wants, needs, finances, etc. Demolition was extremely fast, and the teams made sure to keep the house as clean as possible throughout the entire process. Each person who worked on our house demonstrated a dedication to quality, and whenever an issue arose, it was rapidly addressed and remedied. The workmanship is noteworthy. When it came down to the final punch list, and fixing the minor details (I tend to be fastidious and overly observant about the detail work), there was no issue, and the work was beautifully completed. The billing and payment process is comprehensive, very clearcut and very easy to understand and follow from the outset, which also made the experience seamless. I would like to mention that dRemodeling has a cleaning team that they have clean the areas that have not only been worked on but also impacted by the construction. We found that they are now offering the cleaning team as a separate service, called dReal Deal Clean. It was a no-brainer to sign up for future ongoing cleaning services, knowing that they have the same ownership, and high standards. We will unhesitatingly hire dRemodeling for any future remodeling needs."

Basement leak repair services FAQs
The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
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.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
