"Had basement windows installed. Great job, explained everything. The windows were the original ones. They covered the floors and the basement steps, cleaned up everything afterwards."

"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."

"I can not say enough about Perry Hall Remodeling. I was referred to them by my brother, who also had his basement finished a couple years ago. They did an absolutely phenomenal job. What I found most impressive was their responsiveness, professionalism, and punctuality. Even for the first consultation, Gary Sr. stated he would be at my residence at a certain time, and they were right on time, not one minute late. They took their time to tour the basement, and have us explain what we wanted to have done, while they took time out and suggested certain items along the way. They were up front with cost estimates and time frame of when it would be started since estimate start date was months away. They were punctual with the itemized estimate which was very fair and that all materials would be at cost, no hidden charges. When it came time to start, again they were here right on time, 7:30am, every single day. They provided receipts for all materials so you knew how much exactly it was costing and could keep track. They arrived on time every single day and worked very clean and swept up after they were done for the day. They were very professional and respectful to your property. Probably what impressed me the most was the communication between Gary Sr. and Gary Jr. via email/text. The communication was instant. Whether it was to check on the upcoming schedule or any issues, it was communicated and would be resolved instantly. I was able to keep track of all expenses (which is great for your budget) and they would update you along the way with any payments needed. In the end, the basement looks absolutely stunning in every way imaginable and we could not be happier. I would not hesitate to work with them again for any home improvement needs. A+!!"

"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."

"I needed a complete basement remodel, which also included electrical wiring. When I presented my ideas to Qualified Remodlers, the owner, Joe listened and asked questions to get an understanding of exactly what I wanted. Joe presented a better plan and a way for me to stay within my budget. This company has an excellent crew who work fast and produce outstanding work. Due to the outstanding job that they were doing with the basement, I also hired Qualified Remodlers to paint the siding and all other exterior trim of my house. I am pleased with this work also. The basement remodel is beyond my greatest expectations, and I look forward to hiring Qualified Remodelers for future projects."

"We recently completed a bathroom remodel and are extremely happy with the results. From the initial consultation through the final walkthrough, the process was professional, well-organized, and transparent. Communication was clear at every stage, timelines were respected, and any questions or adjustments were handled promptly. The workmanship is excellent—attention to detail shows in the tile work, fixtures, and overall finish. The crew was punctual, respectful of our home, and kept the work area clean throughout the project. The final result looks modern, functional, and significantly improved both the appearance and usability of the space. We would confidently recommend this team to anyone considering a bathroom remodel and would not hesitate to work with them again."

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.
