"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"

"We had a great experience with the Lux Renovations and Owens Corning team. The whole process was very easy from designing the space, selecting colors, and having a contract manager who organized the entire basement remodel including all the trades and inspections. We were sold on the Owens Corning materials for the basement and that they were engineered specifically for a basement space. Would highly recommend this team for your basement remodel needs."

"I had a leak upstairs in my 2nd floor bathroom which in turn ruined most of my first floor ceiling and floors. It was stressful and I was not sure what to do first despite my insurance covering the damages. Trying to find the right people was very difficult. After much research and multiple quotes, I decided to go with JA DRYWALL. From the first day Isaias came to give me the quote, to the last day his father, George finished the painting... JA DRYWALL did what was promised and more. After each day of work, house was cleaned and livable. All of the JA DRYWALL employees were professional and courteous. It is good to know that I was able to trust a company to do the work as promised without any worries. Thank you JA DRYWALL for making my home looking like it was before the leak... It looks like a brand new ceiling. Your work and professionalism is amazing."

Basement Remodel FAQs, answered by experts

Save money on your basement finishing project by making cost-effective decisions such as minimizing structural changes and avoiding costly construction revisions. DIY simpler tasks such as painting or basic cleanup to reduce labor costs. You can also opt for energy-efficient fixtures and materials that may qualify for rebates or tax incentives.

Framing a basement takes three to five days, on average, when completed by a professional, though it may take longer for a larger space. Keep in mind this doesn’t include the time to complete the design, obtain permits, and install the drywall on the framing. On average, fully finishing a basement takes an average of 45 days.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.

Yes, you can install a summer kitchen or kitchenette in your basement. They serve similar purposes as outdoor kitchens, keeping the main floor of the house cool and providing another space to cook and congregate. Basement kitchens are also a worthwhile alternative for homeowners without much space in the backyard. They come with a few logistical questions to sort out, though, like ventilation and waterproofing.

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.
