"Hired them for 3 projects I have installed this basement waterproofing solution in 2 homes. System speaks for itself. Nothing better on the market. Work was first rate. Expectations were presented prior to the project. Details on what would happen and how the project would go. Would not hesitate to use again ERV installed New basement egress. This project did not go as planned, but not at the fault of basement systems. Was originally supposed to get a BILCO door but due to unforseen issues, that was not able to happen. They ended up installing a new staircase from my basement to ground level. Work was first rate and ended up better than a bilco door. Company re landscaped and everything is as it was. All work performed was top notch and no issues on anything they have done"

"We are currently happy with the basement waterproofing and remodeling that was completed! There were issues - most minor but we haven't anything to compare as this was the first-time having contractors complete basement work for us; and our home is almost 100 years old. They were flexible given unexpected issues that came about with the basement. The water proofing was done first and they did a great job. They were happy to review and resolve any remaining questions/concerns and/or issues. Jorge in the service dept. is professional, punctual and is a great representative and asset for this company."

"Excellent - an outstanding job. The owner (Gary) did the initial estimate (which was the best of five contractors). A very professional and efficient crew started and completed the job on time with no issues. I will definitely include Perryhall Remodeling for all of my future home improvement projects."

"Precision Remodeling did a phenomenal job rebuilding my leaky basement shower stall the result of poor installation from another contractor this spring. Jamie reassured me that his company uses quality waterproofing materials (Wedi) and employs skilled tradesman. Kirk, the plumbing technician, discovered a secondary leak in the piping and was able to correct the issue before shower installation. Steve meticulously waterproofed and tiled the shower in an intricate herringbone pattern. Grout lines are to perfection and no leaks! Jamie kept me informed of every aspect of the project. All members of the team were prompt, courteous, and clean. Precision Remodeling has earned my trust as a top-rated company. I look forward to my next full bath remodel."

"Mr. Ronald Penate did an incredible job demolishing my old uneven floor tile in the bathroom in my basement. Prior to doing the job, we met at Home Depot - where he told and showed me the materials I needed for the job. I purchased the materials and he took them home with him, so that he could bring everything in the morning. On the day of the job, he demolished the entire floor in a single day. He came back the next day, showed me different patterns to lay the tiles, and I told him which one was my preference. He went to town, worked very smart for the whole day, finished installing the tiles. He grouted the next day. 
Additionally, he caulked my shower to make it look neat. Mr. Penate is incredibly dedicated to his craft and is very easy to work with. He's returning this evening to install a back splash in the bathroom where he installed the toilet for a finished look. I have other tiling projects which I hope to use him for."

FAQs for basement remodeling projects in Long-green, MD

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.
