"We are currently happy with the basement waterproofing and remodeling that was completed! There were issues - most minor but we haven't anything to compare as this was the first-time having contractors complete basement work for us; and our home is almost 100 years old. They were flexible given unexpected issues that came about with the basement. The water proofing was done first and they did a great job. They were happy to review and resolve any remaining questions/concerns and/or issues. Jorge in the service dept. is professional, punctual and is a great representative and asset for this company."

"Hired them for 3 projects I have installed this basement waterproofing solution in 2 homes. System speaks for itself. Nothing better on the market. Work was first rate. Expectations were presented prior to the project. Details on what would happen and how the project would go. Would not hesitate to use again ERV installed New basement egress. This project did not go as planned, but not at the fault of basement systems. Was originally supposed to get a BILCO door but due to unforseen issues, that was not able to happen. They ended up installing a new staircase from my basement to ground level. Work was first rate and ended up better than a bilco door. Company re landscaped and everything is as it was. All work performed was top notch and no issues on anything they have done"

"I am very pleased with the work S&J Painting & Remodeling did for me. They painted the ceilings, walls, and trim in my foyer, kitchen, eat-in kitchen area, and family room. The project began and concluded as scheduled. Their team was conscientious and professional while in my home, and diligently cleaned the area before leaving each afternoon. When I asked for a couple of very minor touch ups after the end of the project, they responded quickly. Overall, a great experience and I would happily engage their services again."

"Jon and his team just completed my basement remodel which included digging out the foundation, installing a sump pump as well as all the work to convert it from a dark cave to a bright, beautiful home office and gym. Since the day they started Jon over communicated, made sure I understood every step and patiently answered my endless questions. He was onsite frequently to ensure things went well and made the process significantly less stressful. The end result surpassed all my expectations, I can’t recommend him and his team enough. Everyone from his office manager, to each crew member went above and beyond. Thank you all for a job well done!"

Basement Remodel FAQs, answered by experts

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. 

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

In addition to overseeing new home builds, construction managers work on large renovations and major remodels. For example, they may work with designers and oversee the construction of a finished basement, kitchen renovation, or a home addition. They may also oversee large-scale remodels, such as the update of a historic home. Construction managers step into small projects for more specific assistance, such as building budgets and compiling the team.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.
