"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."

"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 used MDD for a complete kitchen remodel, down to the studs, and are so pleased with the results! Matt and his team are professional, hardworking, and efficient. We changed the project on Matt a few times throughout the process and he was always patient and willing to take the time to make the project exactly how we envisioned it. The other contractors/vendors Matt used to complete the project were all very knowledgeable and professional as well. Matt did a great job overseeing the entire project, while keeping us within budget and on time. We would recommend MDD Construction to anyone who is looking for a reliable contractor who does beautiful work!"

"After several years of Manfredia's Carpentry doing projects at my home, there is no other company I trust more. Attention to detail, superior work ethic, and, quite frankly, a pleasure to have in or around the house with their professional and friendly ways. I can always trust in the crews and their workmanship. They just finished putting in a glass sliding door, and have completely redone my basement walls, floors, windows and plumbing. Absolutely the best. HIRE THEM."

"My wife found Dan through a Home Advisor search. We did a complete full bathroom remodel/reconfiguration. Dan left an immediate overwhelming positive impression the first time he came out. He provided design and reconfigure consultation that we were expecting to use a separate designer and/or architect for. His past work speaks for itself and he has a tremendous amount of experience and examples to pull from to offer suggestions that aligned with our tastes just from speaking through the project with him. Dan is extremely professional and courteous and maintained impeccable cleanliness and constant communication throughout the job. In addition to his promoted services, Dan is skilled in all areas of home improvement and completed some other handyman services throughout the project. I highly recommend him for any project. I plan on contacting him for any future work I need done."

"It was a wonderful experience. Matt knew what he was doing. He listened to what we wanted and made sure we got what we wanted. He had suggested we visit a Cabinet maker store in Lancaster and after doing that we found the perfect cabinets for us. His work is excellent. He is very efficient and neat. Even with our changes he was able to maintain and keep the project on schedule. On a personal level he and his helper were very nice. I would highly recommend Matt to anyone and we are having him come back to do other projects."

FAQs for basement remodeling projects in Wallingford, PA

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
