"We loved working with Joe and the team. They were reasonably priced, responsive to calls and questions, showed up on time, worked hard, cleaned up as they went and were pleasant to have around. They took a lot of worry out of the process. We would definitely work with them again and recommend them to others. "

"Steve did an amazing job renovating two of our bathrooms. He completely gutted our shower and made everything level. He chose great materials and helped us stay on budget. We are asking him to do another project in the spring for us. "

"Our existing Owens Corning wall panels had been damaged in a basement flood. Although the framework and panels had changed since our initial install some 20 years ago, they custom made new panels that fit perfectly. Additionally, they replaced interior doors and repaired drywall. The work was done on our schedule and done to our satisfaction. Their customer service was great. They came back out to adjust a door that wasn't closing perfectly."

"Bad Experience. Bait and Switched us. Told us the no more than cost of our removal verbally and then said he needed $4k to do the design with us and get final firm contract after that. I told him I was skeptical giving him $4k and then have him come back with contract stating it would cost a big percent more. He assured me “he is not that kind of guy”. Then after the design and a smaller scope he wanted to charge us 30% more. Took our money and we now have to start over with a new contractor."

"I had my 1960s paneled and drop ceiling basement room remodeled. I cannot tell you how pleased I am at the upgrade. Along the way Gary answered many emails and calls in a timely manner, usually within the hour. He gave me updates of when certain parts of the project would be worked on and made suggests on things that I hadn’t thought about ( like replacing the drafty original windows while construction was happening). He picked out doors and ceiling fans that were perfect since I am not good at decorating. Because GJP has all their own contractors there was no wait time between the remodeling of the walls and the electrical work that needed to be done. All the workers were do polite and diligent and cleaned up the area. I cannot put into words how wonderful the whole process has been and have already given references to friends. "

"We worked with Gary at Legacy Construction Company to replace the rear roof and siding on our upper floor, along with two windows, and are very pleased with the work he and his team did. Gary took time to explain the pros and cons of our options, provided siding samples and was communicative and responsive. The invoicing and payment schedule was straightforward and easy to use. The work is high quality (having survived multiple rainstorm and snowstorms at this point!), and the team was able to do it in a day once all the materials were ready, making our lives much easier. The adage “you get what you pay for” holds true; Legacy Construction was worth every penny and we are considering them for future renovations."

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.
