"I originally hired Wally to replace two support beams that span a bilco opening on my 200+ year old stone house. The job was very delicate because temporary supports had to be installed before the original log beams could be removed. I had visions of my entire 3-story stone wall collapsing, but once I saw how meticulously his crew worked and the incredible results I knew that it had been done right. Once I realized Wally’s ability, I quickly hired him to do other repairs which included: -Replacing a beam in the basement -Thorosealing the stone foundation wall in the basement -Replacing two concrete pads on my sidewalk that were cracked -Fixing a 3’x3’ sink hole in my driveway -Pour a concrete pad for my Generac generator to sit on -Filling in an old vent hole and landscaping to ensure that the ground next to the house slopes away from the house When it comes to your home, there is little that Wally and his team can’t do. I give Manfredia's Carpentry my highest recommendation."

"The crew at Tedesco Construction were amazing to work with. They did a great job with a high skill level and attention to detail. We are so happy with the outcome of our projects. Apart from the basement remodel we also gutted a bathroom which turned out beautiful. They were also quick to offer good ideas. Besides being great at their job, the crew is very personable and fun. It really helps when you have people in your house for a longer period of time. Overall we highly recommend PG Tedesco Construction!"

"It was a wonderful experience. Matt knew what he was doing. He listened to what we wanted and made sure we got what we wanted. He had suggested we visit a Cabinet maker store in Lancaster and after doing that we found the perfect cabinets for us. His work is excellent. He is very efficient and neat. Even with our changes he was able to maintain and keep the project on schedule. On a personal level he and his helper were very nice. I would highly recommend Matt to anyone and we are having him come back to do other projects."

Basement Remodel FAQs, answered by experts

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote.
