We tell you exactly what you need — nothing more. If a simple crack injection will do the job, that's what we recommend. We're not going to sell you a $15,000 pier system for a $500 problem.
Our structural repairs come with a written warranty that transfers to the new owner if you sell. That's a real value-add when it comes time to close.
Most inspections happen within 3–5 days of your call. Many repairs can be completed in a single day. We know you can't leave a compromised foundation sitting for weeks.
We're not a national chain. We're a Philadelphia family business — started here, grew here, and we're accountable to the neighbors we work for. You'll actually get the owner on the phone.
We understand Philadelphia's unique challenges: expansive clay soil, century-old brick foundations, older drainage systems, and the specific settlement patterns in different neighborhoods.
Foundation repairs can be expensive and unexpected. We offer flexible financing options so you don't have to put off critical structural work because of cash flow.
Over 140 five-star reviews across Google and Yelp from homeowners across the city.
"We have a 1920s rowhouse in South Philly and noticed a big horizontal crack in our basement wall. I was terrified about what it would cost. They came out, explained exactly what was happening with the clay soil and hydrostatic pressure, gave us a fair estimate, and fixed it in one day. The whole crew was professional and they cleaned up after themselves. Highly recommend."
"Three quotes and these guys were the most honest. One company tried to sell me a $22,000 pier system. Philadelphia Foundation came in, looked at the actual cracks, told me I needed carbon fiber straps on two walls — $7,400 — and said the other wall was fine. Saved me a fortune. Work was done clean and they left me with a transferable warranty. Already passed it on to the new buyers when I sold."
"My Manayunk home had serious settling issues — the back of the house had dropped almost 2 inches over 30 years. They installed helical piers, lifted the foundation, and stabilized it. The sticking doors and cracked drywall are gone. It's been 18 months and everything is still level. Worth every penny and way less than I expected."

The most common warning signs are: cracks in your foundation walls (especially horizontal or stair-step cracks), doors or windows that stick or won't close properly, floors that feel uneven or "spongy," water intrusion in your basement after rain, and walls that appear to lean inward. In Philadelphia, expansive clay soil means foundation movement is especially common in older homes. If you notice any of these signs, it's worth having an inspection — many issues are minor and inexpensive to fix if caught early.
Costs vary widely depending on the type and severity of the problem. Minor crack injections typically run $500–$2,500. Carbon fiber strap installations for bowing walls average $4,000–$8,000. Full pier system installations for settling foundations can range from $8,000–$25,000+. The best way to know is to get a free inspection — there's no reliable way to estimate without seeing the foundation in person. See our detailed Philadelphia foundation repair cost guide.
Philadelphia sits on expansive clay soil that swells when wet and shrinks when dry. This constant expansion and contraction creates enormous lateral pressure on foundation walls — especially the older brick and stone foundations common in South Philly, Fishtown, and other older neighborhoods. Add in the fact that many Philly homes are 80–120 years old, and you have the perfect combination for foundation issues. It doesn't mean your house is a lost cause — it just means you need a contractor who understands these local conditions.
Absolutely — we do it all the time. Rowhouses present some unique challenges (shared walls, limited access, narrow driveways) but we've developed techniques over 20 years that make repairs efficient in rowhouse settings. We work around Philadelphia's tight urban lots constantly. Most repairs don't require excavation and can be done from inside the basement, which keeps the job clean and fast even in dense neighborhoods.
It depends on the scope of work. Interior crack injections and carbon fiber strap installations typically don't require permits in Philadelphia. Major structural repairs — like pier installations that lift and stabilize a foundation — may require a permit from Philadelphia's Department of Licenses and Inspections (L&I). We handle all permitting for jobs that require it. We'll let you know upfront during the inspection what's required and what the process looks like.
