"Danny and his team were very professional, on time, communicative, her;pful with suggestions, and overall did a great job replacing our exterior door and storm door. H e even has put in a mail slot in the exterior door for me , which came out beautifully. They are experts at what they do, and meticulous with attention to detail. I would recommend this company highly for anyone that needs doors and /or any construction projects done. Definitely a 5 star company. "

Customers say: Quality work

"Peter really was the key to getting my deck in shape. Many boards were rotted or splintered and I wanted to replace just those. He convinced me that the results would not be good if over half the boards were different. I replaced the entire deck. PJP's price was competetive. The workmen were highly qualified and dedicated and did a clean and efficient job. Especially nice job on a new set of stairs from the deck to a patio. Highly satisfied and easy to work with all around."

"Absolutely amazing experience. SO EFFICIENT, always on time, GREAT value, unbelievable communication, and tremendous transparency. The contractors were so GREAT at what they do, and were clean and always on time. No hidden costs or expense (which you deal with with MOST contractors). This is not the best contracting company I have worked with, this is the BEST COMPANY I have ever worked with."

FAQs for basement remodeling projects in Hewlett, NY

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.
