"Cesar remodeled our basement, and we cannot be happier with his work! He worked with us the whole way to make sure we were happy with the work. He even put a custom wine rack in. The new basement is so beautiful and we get so many compliments. He has done work for us before and he does excellent work, is always available and easy to reach, and has a professional and kind team of workers. Thank you Cesar!!"

"AMAZING. Angelo is professional, responsive, he has a great team who does top notch work. My wife and I asked him to remodel our sun room, they made such an amazing room for our family we ended up asking them to re-wrap the entire house. So glad we found CR, and they better stay by the phone because we’ll have more work to be done."

Customers say: Quality work

"We hired Ernest and Sons to construct our patio tiles. We purchased 2' X 2' Tiles and I have to say they did a gorgeous job. I was so pleased with the way they showed up when they said they would. The men that laid out on my job worked so hard. The labor was very strenuous but they never took a break. They were the most conscientious and polite workers I've ever dealt with. They worked neatly, cleaned up totally afterward, and just had a great deal of respect for our property. They really did a beautiful job and Ernest, the owner is a real gentleman also. Love this company!"

"We have had DDP (Dariusz Pardo and his great crew) do substantial projects for us since 2015 - interior painting and kitchen remodel for my motherâ s condo, exterior painting of our house - so when we decided to do a major refresh and renovation of our house, DDP was our first choice. That was a smart move! After much discussion and thought, we agreed on an expansive project list. * New kitchen: cabinets, quartz countertops, crown molding, ceramic backsplash, porcelain floor, ceiling and under-counter lighting * Replace hardwood floors (rip out hardwood, screw down sub-flooring, install and finish new flooring) * Replace interior doors (19) and door moldings * Replace all baseboard moldings * Build new Pantry and laundry room closets and remodel all other closets * Family Room: Design and install new in ceiling lighting, and install new laminate flooring * Replace all electrical switches and outlets, and install several new outlets in kitchen, bedrooms and family room * Fix creaky stairs * Adjust step height of several stair steps * Paint every room and closet, which required resurfacing of many areas that had deep cracking/peeling of 60 years worth of paint. * Design and install plumbing for a new water softener system, and install system * Install new natural gas Hot Water Heater including leak detector with automatic water shut-off. Along the way, Dariusz made numerous helpful suggestions and incidental improvements, driven by his high standard of design and desire to deliver the best possible results. The projects took about 13 weeks to complete - pretty quick for all the work that was done. The end result is spectacular - we have transformed our tired old house! We are delighted with our new home! Friends and family who have visited are amazed at how beautiful everything is, and how many improvements were made to make cabinets, closets and other spaces much more useful. The kitchen tops the list. We LOVE our new kitchen! It looks beautiful and all our friends and family agree. In fact, a cousin who visited in October told me that she â covetsâ our kitchen - and that is passionate praise coming from a pastor! Bottom line: donâ t hesitate to engage DDP for any project. Darius Pardo and DDP Construction LLC are the absolute BEST. Our friends who have also engaged Dariusz say the same thing."

"We had our paver patio done with Fresh Contracting, and we couldn't be happier. The team was very professional and friendly during the process. They did a great job from start to finish. They gave us good ideas to make the most of our space, and the work looks neat and tidy. The team kept us in the loop, finished when they said they would, and always cleaned up after themselves. If you want someone you can trust for your outdoor project, Fresh Contracting is a great choice."

Basement Remodel questions, answered by experts

The average cost to remodel a basement is between $12,100 and $33,400. Depending on the project's complexity, the price can be as low as $3,500 or exceed $50,200. For a simple project like adding a home office, you might spend between $500 and $3,000. However, a more extensive project, such as adding a bathroom, can range from $6,600 to $16,500. The final cost is influenced by factors like the basement's size and condition, the type of remodel, material choices, your location, and accessibility. For an accurate price, it's best to consult with a basement remodeling team.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.
