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 Pittsburgh

If your basement leaks after every storm, your walls are cracking, or your floors slope toward one side of the house — the clay soil underneath is the reason. It swells when it rains, shrinks when it dries, and never stops moving. Homes here were built on it decades ago, and the damage shows up a little more every year.

Cracked foundation showing signs of structural damage

Foundation Repair

Your doors stick. Your floors slope. There are stair-step cracks running through the brick outside. The clay underneath your home expands and contracts with every season, and on hillside lots it pushes harder on one side than the other. That is why the settling gets worse instead of better. We stabilize it so the movement stops.

Standing water in basement requiring waterproofing

Basement Waterproofing

You found water on the basement floor after the last storm. It came in where the wall meets the floor, through cracked mortar joints, or along gaps in old sandstone that have been opening wider every winter. These walls were never built to keep water out. We find every entry point and route the water to a pump before it reaches your floor.

Steel crawl space jack posts installed on concrete footings

Crawl Space Repair

Your floors bounce when you walk across them. The beams underneath are soft and the supports are leaning. Moisture from bare ground has been weakening the wood for years. We replace what has failed, re-level your floors, and reinforce the structure so the bounce stops.

Crawl space with vapor barrier encapsulation installed

Crawl Space Encapsulation

That musty smell in your house starts underneath it. Open vents and bare dirt pull moisture into the crawl space all year long. That moisture feeds mold and rots your floor joists from below. We seal the entire space with a vapor barrier and dehumidifier so the moisture stops at the source.

Sump pump in a basement pit

Sump Pump Installation

Your pump runs constantly during storms. Or it does not have a backup and you lose power during the worst ones. Either way, it is one failure away from a flooded basement. We install systems with battery backup so the water keeps moving out even when the lights go off.

French drain system installed along foundation

French Drain Installation

Water is sitting against your foundation walls and building pressure. In row home neighborhoods with three feet between houses and no room to dig outside, an interior French drain is the fix. It catches water along the inside perimeter and moves it to the sump pump before it hits your floor.

How Foundation Repair Works

Getting started is simple. Here's what to expect when you work with us.

Step 1
Schedule Your Free Inspection
Call or fill out the form. We come out and look at everything — basement walls, floor slopes, cracks inside and out, grading, gutters. No cost. No obligation.
Step 2
Get a Straight Answer
We tell you what we find in plain language. If it does not need repair, we say so. If fixing your gutters and regrading solves it, we tell you that instead of selling you something bigger.
Step 3
Review Your Options
You get a written proposal with the scope, method, and price. Not just the most expensive option. Take it home, compare with other companies, ask us anything.
Step 4
We Fix It Right
Our crew shows up on time, does the work, and cleans up. You get warranty documentation and a walkthrough of everything we did before we leave.

You already know something is wrong. You need someone who will tell you the truth about what it is, what it takes to fix it, and what you can skip.

Why Pittsburgh Homeowners Call Us First

You already know something is wrong. You need someone who will tell you the truth about what it is, what it takes to fix it, and what you can skip.

We Tell You What You Do Not Need

Bad gutters and flat grading cause half the wet basements we see. If that is all your home needs, we tell you before recommending anything else. A lot of companies skip that conversation because there is no money in it.

We Know How These Homes Break

Sandstone foundations in Lawrenceville that have been crumbling for a hundred years. Block walls bowing inward in Beechview from clay pressure. Row homes in Bloomfield with no room to dig outside. Hillside lots on Mount Washington where the soil slides after every heavy rain. Each one fails differently. We have fixed all of them.

The Warranty Transfers When You Sell

Every structural repair comes with a transferable warranty. If you sell your home, the coverage goes with it. A foundation that has been repaired and documented is a selling point — not something that kills the deal during inspection.

Foundation Repair Questions Pittsburgh Homeowners Ask

These are the questions we hear most before someone schedules an inspection.

It depends on what needs to be done, how much access we have, and how far the damage has gone. Sealing a single crack is a different job than bracing a bowing wall or waterproofing an entire basement perimeter. We give you a written quote during your free inspection so you know the exact number before any work starts. Financing available.

Water gets in where the wall meets the floor, through cracked mortar, and along old stone joints. The clay soil outside swells with rain and pushes water against your walls. The combined sewer system can also back up during storms — as little as a tenth of an inch of rain can overwhelm it and send water through your floor drain. A free inspection shows you exactly where the water is getting in and what stops it.

Clay soil expands when it gets wet and pushes against your basement wall. On hillside lots, the uphill side takes the full weight. Over time that pressure bows the wall inward. Freeze-thaw makes it worse every winter — water in the soil freezes, expands, and pushes again. If you see a horizontal crack running across the middle of the wall, that is the pressure line. We stop the movement and brace the wall so it holds.

Most jobs finish in one to five days. A crack repair takes a few hours. A sump pump install takes a day. French drains run two to four days. Pier work runs two to three days depending on how many are needed. You do not need to move out.

Exterior waterproofing means digging down to the footing and sealing the wall from the outside. It stops water at the source but requires full excavation — and on row home lots with no space between houses, it is often not possible. Interior waterproofing catches water along the inside perimeter with a French drain and routes it to a sump pump before it hits your floor. Both work. Which one fits depends on your home, your lot, and where the water is coming in. We walk you through both options during your free inspection.
