"My husband and I were very impressed with AMJ Construction. Anthony and his helpers took their time with removing the old doors, replacing it with the new one. They were meticulous about the work being done. The helpers were respectful and answered any questions we may of had. By the end of the job the work area was immaculate. Anthony’s assistant Tracy at the office was patient and very pleasant to work with. We will definitely hire AMJ Construction again for another project."

Customers say: True professional

"If you’re looking for reliable, honest, and hardworking contractors, Rettle Enterprise is the best choice. They have now completed two big projects for me and my family, and both times they were professional, dependable, and went absolutely above and beyond our expectations. They first added a kitchen to the lower level of our home, and more recently, they completely redid and cleaned up the mess left behind by another contractor in our downstairs bathroom. The quality of their work, attention to detail, and professionalism really stand out. I absolutely wouldn’t trust anyone else to work on our home. If we have another project in the future, Rettle Enterprise will be the first and only contractor we call. Highly recommend!"

"We hired Jimmy Wrenn for a full basement remodel, and we couldn’t be happier with the results. From the initial consultation to the final walkthrough, the communication was clear, honest, and professional. The crew showed up on time, kept the work area clean, and paid close attention to detail throughout the project. The quality of the work exceeded our expectations, and the project was completed on schedule and within budget. Any questions or small changes we had were handled quickly and without hassle. Our basement has been completely transformed into a beautiful, functional space, and we’ve already received compliments from friends and family. I would highly recommend Jimmy Wrenn to anyone looking for reliable, high-quality remodeling work."

FAQs for basement remodeling projects in Lake Harmony, 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.
