Excellent work from Queen Foundation Repair! From beginning to end, the crew operated with efficiency and professionalism. Carlos and his team completed the foundation repair project in less than four days, and even our neighbors have complimented the immediate transformation. I highly recommend them for foundation work, foundation repair, and water restoration.

Hi, I had some cracks in my foundation after purchasing my new home and was concerned about them. Queen Foundation Repair made everything a very easy and stress-free process. They came out and repaired these cracks within a day, and the crew, including Dario and Sharon, was very knowledgeable. Thanks very much!

I cannot say enough about these guys — they were a pleasure to work with. Sharon, who was extremely knowledgeable, handled the scheduling, and Carlos and Dario did the assessment and repair of the foundation issues we were having. They answered every question we had, showed up exactly when they said they would, and back all of their work with a lifetime guarantee. Your search for a foundation repair company is over!

I'm very pleased with the results. I can clearly see the excellent work Jason's crew did on our crawl space. His team was friendly and left the property clean. This is the first time I've posted a review because I think people should know about them. Call them when you need crawl space repairs in Albany NY!

The customer care provided by Queen Foundation repair was exceptional. From the first contact to the final walkthrough, they were attentive, informative, and very responsive to my questions and concerns. They took the time to explain the encapsulation process and how it would benefit my home. Their crew was respectful and ensured that the work was completed to a high standard. It's clear that they value their customers and take pride in their work. Our crawl space is now dry, clean, and well-insulated. Highly recommended!

I'm absolutely delighted with the exceptional assessment service provided by Queen Foundation Repair! When I noticed sloping floors in our bungalow, I knew I needed expert help. Scheduling an assessment was a breeze via email, and John arrived promptly as scheduled. His warm and personable demeanor put me at ease, and his expertise shone through as he quickly identified the root cause of our issue.

I reached out to this company about an issue they couldn't handle, but they were very responsive. They did a thorough inspection and gave recommendations related to their specialty. They even provided a reference number for another company that could help with our issue. They're great for foundation repair work, and I'd definitely recommend them.

Germao and his crew installed helical piers and expertly stabilized our foundation. The crew was professional and responsive to our needs. I'm happy with their foundation repair service.

Foundation & Waterproofing Services in Philadelphia

Most homes here sit on stone or brick foundations that are 80 to 130 years old. The clay soil swells when it rains and shrinks when it dries. That cycle causes cracks, settling, and water problems that get worse every season.

Cracked foundation showing signs of structural damage

Foundation Repair

Stair-step cracks in your brick, doors that stick, or floors that slope — these are signs your foundation has shifted. The clay underneath expands and contracts every season, and in homes with shared walls, that movement pulls on the house next door too. We stabilize it so the shifting stops for good.

Standing water in basement requiring waterproofing

Basement Waterproofing

Water pooling on your basement floor after a storm is the most common problem we see. Older foundations were never built to keep basements dry. Water gets in where the wall meets the floor, through cracked mortar, and along old stone joints. We find every entry point and put a system in place that moves the water out before it causes damage.

Steel crawl space jack posts installed on concrete footings

Crawl Space Repair

Bouncy floors, sagging beams, or wood rot underneath your home means the crawl space structure is failing. We replace damaged supports, re-level your floors, and reinforce everything so your home feels solid again.

Crawl space with vapor barrier encapsulation installed

Crawl Space Encapsulation

Open vents and bare dirt pull moisture under your home all year. That moisture feeds mold, rots floor joists, and makes your house smell musty. We seal the entire space with a vapor barrier and dehumidifier to keep it dry year-round.

Sump pump in a basement pit

Sump Pump Installation

A sump pump removes water before it damages your home. Storms here knock out power while dumping inches of rain, so a primary pump alone is not enough. We install systems with battery backup so your home stays protected even when the lights go out.

French drain system installed along foundation

French Drain Installation

Water sitting along your foundation walls puts pressure on them and eventually finds a way inside. In older homes where you cannot dig from the outside, an interior French drain catches water along the perimeter and routes it to the sump pump before it hits your floor.

Why Homeowners Here Call Us First

When something is wrong with your foundation, you need someone who will be straight with you and only fix what actually needs fixing.

We Tell You What You Do Not Need

Gutters and grading fix half the water problems we see. If that is all your home needs, we will tell you before recommending anything bigger. We would rather be honest than sell you work you do not need.

We Know These Homes

Rubble stone in Germantown. Brick in South Philly. Poured concrete in the northeast. Each one fails differently. We have worked on all of them and know what each type needs.

Warranty That Transfers

Every structural repair comes with a transferable warranty. If you sell your home, the coverage goes with it. That turns a repaired foundation into a selling point.

Foundation Repair Questions

What homeowners ask us most before scheduling an inspection.

It depends on the type of repair, how much access we have, and how far the damage has gone. A crack repair is a different scope than stabilizing a bowing wall or waterproofing an entire basement. We give you a written quote during your free inspection so you know the exact number before any work starts. Financing available.

Water usually gets in where the wall meets the floor, through cracked mortar, or along old stone joints. The clay soil outside swells with rain and pushes water against your walls. During heavy storms, the combined sewer system can also back up through floor drains. A free inspection shows you exactly where it is coming in and what stops it.

Yes. Open vents pull moisture under your home all year. That moisture causes mold, rots your floor joists, and makes the house smell. Encapsulation seals the space and controls the moisture at the source. Most homeowners notice the smell gone within a week or two.

Most jobs finish in one to five days. Crack repair takes a few hours. A sump pump takes a day. French drains run two to four days. Pier work is two to three days. You do not need to move out.

Depends on the crack. Hairline shrinkage cracks can be monitored. Horizontal cracks, diagonal cracks from window corners, or stair-step cracks in brick mean pressure or movement. Sealing the surface will not fix it if something is still pushing from outside. We diagnose the cause and fix it — not just the crack. Free inspections available.

Yes. We work across the metro area — South Philly, Fishtown, Germantown, Kensington, Manayunk, Roxborough, Northeast Philadelphia, and surrounding communities. We handle homes of every age and foundation type.
