"Mike and Jared installed a second AC system in our attic. They were reasonably priced, super easy to work with and very responsive. The work was done on time and exceeded our expectations so we hired them to completely remodel our master bathroom!"

"I hired Luiz to remove kitchen cabinets, dishwasher, cooktop, oven and lift hardwood flooring. He then reinstalled the cabinets and appliances. Ceramic tile was installed to perfection. He also repaired some walls and painted the ceiling. Looks great! Easy to work with, very professional and fair market value pricing too. Iâ  m recommending him to my family!"

"TJ Kustumz has my very highest recommendation. So far, they have done two jobs for us: a medium size kitchen remodel (tile backsplash, electrical, some cabinet work, install microwave); and a complete replacement of a master bath shower, which was a pretty large project. Tim, Rick and Nick were very honest and professional -- careful in their planning, estimates, and especially in their work. The quality of the work was superb, and Tim was a great creative help as well -- he has a very good eye for design, and suggested many elements of the work that made it far nicer than we originally envisioned. Rick is also very good at creative design. I also want to mention that the entire team was excellent at problem solving -- nothing ever goes exactly as planned; there are always surprises, but nothing fazed these guys, or even slowed them down. Importantly, the tile work was just outstanding; everything was done with precision and attention to detail. Finally, I must note that Tim, Rick and Nick were a pleasure to work with. They are nice people. We are making a list and checking it twice for future projects with them. Richard T. McCoy, Wexford, PA"

"I’d really like to take this time to thank rough diamond construction and Nate Miller for a wonderful wonderful job that they did for us. They took my bathtub and made a walk in shower, beautiful job and moved my washer and dryer upstairs where it was a lot more convenient for me and my husband to do laundry. I can’t thank them enough. They’re very courteous. They’re great if you ever need any kind of work done, I would highly recommend them to do the job. Thank you again Nate thanks for everything."

"We are so glad that we agreed the contract with the BNQ. The whole process was smooth, professional, and transparent. Personally, I like things to be done in a well-organized and transparent way. Carmen was very knowledgeable about what he was doing and made reasonable plans before the job got started. On the arranged date, he and his assistant Ryan arrived on time and very patiently listened to our concerns and plan of changes. They transformed our old closet into a beautiful walking in shower with great functionality. The other project in the kitchen was a little tricky because the original vent opening in the wall. Carmen was very flexible about our design. He took care of the details and found a good solution for the challenging work. We appreciate his commitment to his professional work. Thanks to Carmen and Ryan, now we have a modern looking kitchen with a very efficient wall mounted hood. Moreover, the price is fair. I had a couple of quotes for our projects. BNQ price range is in the middle. However, the result is wonderful and it is totally worth the money. I would highly recommend BNQ to our friends and family!"

"Our furnace went down for a week so our pipes froze and burst... I explained to dreamworks how we were just in a hotel for a week and how we have four kids and that we needed water to come home... Joe and his team came out the very next morning as early as possible to get us up and running... they replaced the bad pipes and restored our water within a couple hours!!! My family is home now because they were fast and most importantly efficient!! I highly recommend!!!"

FAQs for basement remodeling projects in Sewickley, 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.
