"Half the things the salesman told me were not true and no one will return my call about getting a new door for my crawl space. The sump pump works so I guess I should be happy."

"I had Serge and his crew build a studio adjacent to my house. I received 5 quotes and they were the least expensive, used better materials (2 x 6's vs 2 x 4's) and proposed a foundatiom for the hillside project. I am thrilled with the workmanship. We made a number of changes along the way. They wanted to please. I am thrilled."

"The owner was reliable, knowledgable, and informative through the whole process. He and his employes were respectful and did an excellent job. We were pleased that the owner of JDV Contracting not only stayed on budget, but saved us money in areas of materials. When he found deals in areas (such as trim), he upgraded us in other areas (such as solid doors from hollow core doors). Whenever he found he could save in other areas, he checked to see if we wanted upgrades or to keep the items we originally planned! We would definitely recommend and use JDV Contracting again!"

"Delmas and his team were phenomenal. They refinished our sunroom in September 2017 with every attention to detail. They provided insightful ideas that ultimately made our room even better than we could have imagined. His team matched our existing wood work and floors to blend the room in seamlessly with the rest of our house. They listened to what our big concerns were that originally prompted the work and they met our needs and then some. They were easy to reach to discuss any detail as the work progressed and were very open to any changes. His team were very conscientious and left the site cleaned up every day. I would highly recommend them if you are looking for high quality work. I will definitely be using them again for any future work on my home."

"They did such a good job that I requested the same installers to come out both of our door installation jobs (Phil and John). They were very polite and talked to you.  They didn't mind me watching them or taking pictures of the work.  They were friendly and cleaned up afterwards.  They did a really good job and made sure all the work was done without mistakes."

FAQs for basement remodeling projects in Llewellyn, 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.
