"They did a phenomenal job on our two ceilings in this 1890’s home. They showed up on time, were responsive to our questions, worked diligently, completed in time, did a professional job, and the results are beautiful. Their price was reasonable too. I strongly recommend them. "

"Aaron and his assistant did a fantastic job of installing an attic fan in my home. Additionally, they did a phenomenal job of washing and staining my deck. They also did a great job of cleaning a vinyl fence in my yard. I am very impressed with the quality of their work, and looking forward to working with Aaron in the future. Keith W."

"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."

"I gave this man $3000 which was 33% of the job upfront. Was supposed to give him 33% at the halfway part And 34% upon completion. But when I went to my bathroom and realized you left drugs in my bathroom and I have small children. Not like that 3000 black and small cleaners caught easy and heâ s lucky he hasnâ t been charged with nothing. Only reason that happened is because I wouldnâ t pursue charges. He obviously is a drug addict and has a problem so maybe he should get help Possibly isnâ t the option maybe rehab is. If you paid for supplies, you got ripped off wait 10 years and it will all fall apart charges for certain stuff but buys different stuff so he can use the extra money to pick himself up drugs without nobody noticing, I am so terribly in grief over this. $3000 he ran off with how is Matt doing in business and not in a jail cell"

"Frank and his team did excellent work of tearing down an old cedar deck and building a Trex deck. Did a great job of guiding me thru the process of choosing the color schematic of the deck, and options for railing. Due to Covid-19 not all material was available at the same time, Frank was always in contact to let me know the status of material being available so the job could move forward. Easy going and always available to answer any questions you may have about your project. Makes sure you are 100% satisfied. Highly recommend!"

FAQs for basement remodeling projects in Dover, NJ

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.
