"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."

"We recently began planning to renovate our apartment and were searching for an architect who could provide a signed drawing to help us navigate the building permit process. During our search, we had a phone conversation with a project manager from a potential contracting company, and we were thoroughly impressed. He was incredibly patient in listening to the challenges we were facing with obtaining the permit. He took the time to explain each step in great detail, including some critical steps we had missed during our first attempt. His company also has a skilled architect who could handle the drawing process. What stood out the most was the project manager’s solid experience working with government staff for permit approval and his ability to oversee the entire renovation project.

Typically, it’s more affordable to buy an existing home than it is to build a new one. New construction loan interest rates tend to be higher than interest rates for traditional mortgages. Additionally, the cost of materials is likely higher when building a new home than it was when an existing home was built (unless it’s a very new one). You’re also paying for all new appliances, finishes, permits, inspections, and connections for water, gas, and electricity.
One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.
The most common first signs of foundation issues include:
Cracks in the foundation walls that grow
Signs of moisture or water leaking through cracks in the foundation
Standing water in the basement
Sagging floors or walls
Cracked walls in upper floors
Doors and windows that don’t close properly anymore
Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.
If you’re noticing signs of foundation issues, the first step to fixing a foundation problem is to hire a foundation repair inspector. They will determine the problem, the cause, and the severity before recommending a course of action to repair the foundation. The method for fixing foundation problems depends on the problem and what options are available. A few possible solutions include:
Epoxy injections
Mudjacking
Piers made of steel or concrete
Jacks
Hydraulic piers
Carbon or steel reinforcement strips
Waterproofing materials
