"M Phippin did a great job on our 2 room addition. He has the most detailed and easy to understand quote. He stuck to his quote. The work was done in a timely manner considering corona virus came into play towards the end of the remodel. We absolutely love the 2 rooms he did and I wouldn’t think twice to hire him again."

"Joe is very easy to work with. He listened to ideas and followed through. He was there when he said he would be and notified me if he was delayed. The tile work, painting and remodeling work he has done is beautiful. Iâ  m still in the process of making changes to my home and Joe will be my go to person."

"Olgun completed several projects for me at two locations. He built a closet, installed guardrails on the basement staircase, painted rooms, installed outside cameras, installed shower doors, replaced siding, and more. He is polite, professional, and timely. He does quality work at a good price. I recommend Olgun for large and small jobs."

"I can't say enough good things about my experience with Randy Preston and his crew!! Randy helped me renovate a garage that was in SEVERE disrepair into a beautiful and charming studio cottage. The craftsmanship was excellent. I regularly get compliments and feedback that the cottage has the feel of a home that's been there forever (think circa 1940's cottage). The crew was always on time, kept the site neat and clean and were super easy & pleasant to work with. Randy's personality is "steady and calm" - nothing ever felt like a problem - if it was within his power, he handled it and if it wasn't, he helped me figure out next steps. Renovations are rarely stress-free but Randy's nature helped to make it as stress-free as possible. I think the thing I was most impressed with was his transparency and honesty. He was the only contractor that provided me with a fully itemized estimate. I knew exactly how much was budgeted for EVERYTHING and at the end of the construction, he actually credited me back money for things I would have NEVER known cost less then estimated. Every step of the process (that he had control of) was great. I'd hire him again in a heartbeat and hope I do get to use him again for a future project I have in mind. If I haven't gotten the point across yet, I highly highly recommend!!"

"So I been longing to get my basement bathroom done and was very skeptical because I wasn’t sure what I wanted and wasn’t sure if it would come out right…so I searched for a contractor only to find Link Brothers home improvement… Again still skeptical about the finishing look so I crossed my fingers and went with them and when I say I was by far the happiest woman beyond measure… The job they performed and the amount of time was amazing I was ecstatic and I am truly in love with my bathroom…. So if you ask me, with hands down I will recommend Link Brothers Home Improvement with no hesitation!!!"

FAQs for basement remodeling projects in Nassau, DE

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.
