"Tyrell did an excellent job correcting the mistakeS of the people who installed my basement waterproofing equipment. There was a terrible rotten egg smell and that's gone now.

Welcome to Santosusso Construction! Located in Philadelphia, PA. Covering the Tri-State area. We are licensed & insured, offering free estimates. We specialize in residential work including: New Construction, Total Gut Renovations, Remodels, Additions, Decks, Kitchen / Bath, Roofs,Concrete,Basement Dig-outs, Brick Fronts, Demo, Etc. I'm Steve Santosusso owner and operator of Santosusso Construction Inc. Santosusso Construction has been a licensed company since 1988, beginning in Los Angeles, California. After being involved in construction for a number of years, I attended and graduated from Pacific Coast Contractor's School. The curriculum included general knowledge of all trades, estimating, and OSHA laws. In 1993 I moved my company to the East Coast where I've been licensed in PA ever since. We are a small personal company with hands on attention to every project. Our employees are well trained and trust-worthy, as are all sub-contractors, whom I have used for many years. This combination of employees and sub-contractors provides a team atmosphere with quality work as our goal. Check us out on Facebook: https://www.facebook.com/SantosussoConstructionInc/
"Santosusso Construction did an amazing job on stepping in to save the day on a fix and flip project that was started by a previous construction company. It would have been completely understandable if Steve, the owner, would’ve opted out from doing the work. But instead, he jumped in, provided a fair price and brought only licensed and expert tradesmen onto the project to get the property sold. After experiencing his dedication to this project, and seeing first hand that he went above and beyond of what was expected, I hired him to renovate my home. Steve is very thorough, honest and was always ready to answer any questions that I had. He kept me updated daily regarding the progress of the construction and assured me that the renovation would be done on time. I would highly recommend Santosusso Construction over any other construction company in the Delaware Valley. And I will 100% be using them again in the future."

Being in the architecture business for the past 34 years we have the experience and knowledge of building design to offer our clients quality services for their projects.
"We were in the process of renovating our apartment and needed to apply for permits from the government, which required an architect-signed design drawing. Anthony came highly recommended. He took the time to visit our apartment and carefully understand the challenges we faced in obtaining the permits. After thoroughly reviewing the space and listening to our renovation ideas, he assured us that the project would be straightforward for him and that he could provide an architectural drawing that would not only meet our needs but also ensure we could pass inspection without any issues. Despite the project being relatively small, Anthony was more than willing to take it on and offered a very reasonable fee for his services. We truly appreciate the time, care, and professionalism he brought to the table. We would highly recommend Anthony to anyone looking for an architect who is knowledgeable, approachable, and dedicated to delivering great work."

The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
