"We love our basement remodel. Peter, Alex and his team were here when they said theyâ d be here, completed the job as described, and kept us updated along the way. The basement now looks and feels clean and bright. The additional space doesnâ t feel like a basement at all and is enjoyed by the whole family. We highly recommend Lux Renovations."

"We recently completed a full Basement remodeling project for our Home in Montgomeryville – PA with Zwolinski Construction . Not only did they meet the expectations set by neighbors who had worked with them in the past, they also went above and beyond to exceed them and ours. From the start of our design process through remodeling and follow-up, Zwolinski Construction demonstrated their professionalism, expertise, customer service, and true passion for their business. It is clear that their true purpose is to ensure their client’s complete satisfaction, and each and every individual – from owners to designers to contractors to office manager – put in the time, effort, and energy to ensure that they accomplish this goal. Zwolinski Construction has excellent project management capability, ensuring a successful project completion from begin to end, especially when the project scope has been changed. After the contract was signed we added a couple more things. They very clearly outlined "

"We are delighted with the work Total Home Solution performed on our house.  They installed an in-law suite in our basement, complete with bathroom, full kitchen, bedroom, office, and remodeled laundry area.  When meeting with contractors for estimates, Tom seemed the most clued in to the needs of older adults, and even made points I had never thought of despite my being a nurse.  He was very careful to keep everything within the original budgeted estimate as much as possible, which allowed us to expand the project as we went along in the process.  We chose to do the painting ourselves to save money, and they left us with extra spackle, a sander, and paint fan, even though they didn't have to. <br /> I also have to extend my thanks to the lead on the project, Chris.  I could hear them working from upstairs, and one of the subcontractors was a little, shall we say, salty.  Chris remained totally professional, and got all the workers to come together to get the job done right.  Lastly, but most important of all, was his humanity and kindness.  My father passed away unexpectedly the week before construction was to begin, and the funeral was out of town.  As part of our contract, we were supposed to have all furniture and personal belongings removed from the construction area prior to work beginning.  We got home after midnight the night before, and Chris and his team arrived at 7am.  We had not moved any items, and even though we broke the terms of the contract, Chris stepped up and moved everything himself.  He was so kind, and did everything he could so we would not have to worry about anything during a difficult time.  He was also very responsive throughout the project, and even immediately answered emails I sent 9:30 at night the day after he got married!   <br /> We had such a wonderful experience I would highly recommend Tom and Chris to anyone looking to do work on their home, and will call on them for any future home renovation needs. <br /> *Note: I did give them a "B" for responsiveness because they were a little slow in the beginning, but as per other reviews, they had some people out and were running short staffed in November/December.  We chose to begin the project after the New Year and it was smooth sailing after that. <br />"

"We needed to have our basement remodeled, requested a quote, and the owner was onsite in a few days, he was extremely flexible with our busy schedule. He provided us with a quote shortly after in a timely fashion. The work was of high quality, and completed in the estimated time. The overall price was reasonable and the project stayed on budget. Wally and all of his workers were always polite, professional, punctual, and extremely responsive. I would recommend this company to any for any of your home improvement needs. We are extremely satisfied, and look forward to working with Manfredia Carpentry in the future. We love our new basement!!!"

"My wife found Dan through a Home Advisor search. We did a complete full bathroom remodel/reconfiguration. Dan left an immediate overwhelming positive impression the first time he came out. He provided design and reconfigure consultation that we were expecting to use a separate designer and/or architect for. His past work speaks for itself and he has a tremendous amount of experience and examples to pull from to offer suggestions that aligned with our tastes just from speaking through the project with him. Dan is extremely professional and courteous and maintained impeccable cleanliness and constant communication throughout the job. In addition to his promoted services, Dan is skilled in all areas of home improvement and completed some other handyman services throughout the project. I highly recommend him for any project. I plan on contacting him for any future work I need done."

"Matt and his team with MNB Renovations did a 32 x 24 addition that was basically a home build from the ground up. I am still surprised for the size of this project how stress free the process was. Matt was very detailed and checked in on everything to make sure we were getting what we wanted. In the end he asked us to make a list of anything that needed to be addressed and there was absolutely nothing to mention. They did a perfect job, the quality of the work is amazing, and the entire team was very nice, professional, and trustworthy! I absolutely recommend this company to others and will definitely use them again in the future!"

"Couldn’t recommend highly enough! Rick and his team did an excellent job completing several projects in our home including building a gym in the previously unfinished section of our basement, transforming a den into a bar room for entertaining, and coming up with a creative and perfect solution to put an office in our basement. Rick is a great, trustworthy guy and does beautiful work! "

FAQs for basement remodeling projects in Harleysville, PA

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.
