"We love our basement remodel. Peter, Alex and his team were here when they said theyâ d be here, completed the job as described, and kept us updated along the way. The basement now looks and feels clean and bright. The additional space doesnâ t feel like a basement at all and is enjoyed by the whole family. We highly recommend Lux Renovations."

"Had basement windows installed. Great job, explained everything. The windows were the original ones. They covered the floors and the basement steps, cleaned up everything afterwards."

"Paul was excellent to work with. We had to make many changes during our remodel. He was very accommodating and easy to work with. Our ADA remodel to convert a bedroom and bathroom making it wheelchair accessible turned out beautifully! We are very happy and would highly recommend His company ."

"This was an amazing experience, we had never done a renovation like this before and it was due to a pipe exploding in our basement. Not only did Perry and his team do an incredible job, they were unbelievably patient and understanding as we dealt with the insurance company and all the hassles they create. Their experience, craftsmanship, and tremendous customer service made this a wonderful experience and our new basement looks incredible! Thank you all again! We will definitely be using these guys for any future renovations/contracting work."

"Tom and his crew remodeled my kitchen and powder room, and they did an exceptional job! Their price is very competitive and quality is second to none. Tom is extremely knowledgeable, friendly and went the extra mile to make sure that every detail was done right. I would highly recommend Total Home Solution and hope to work with Tom again on other projects in the future."

"The kitchen was completed gutted and rebuilt within 3 weeks. Matt worked with us on every aspect of the remodel and addressed everything we had on our wish list. On all the projects Matt and his people were here every day until the work was completed to our satisfaction. When they left each day the work site was spotless. We have been happy to recommend MNB Renovations to our friends and family and plan on having Matt back when we are ready for our next project(s)."

"Dream come true on my two bathrooms. From beachouse style in one to rustic cabin style in the other, I couldn't be more happier! After my flooring was about to fall through, finding mold in the drywall, and also finding holes in the septic vent pipe that went up through behind the drywall I was glad we did the renovation when we did and were able to resolve all the issues.

FAQs for basement remodeling projects in Downingtown, 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.
