Bowing Basement Walls

Bowing basement walls indicate structural issues, often caused by soil pressure, water damage, or foundation settlement, which can compromise the stability and safety of the building if left untreated.

Drywall Cracks at Door and Window Corners

Drywall cracks at door and windows corners can be signs of foundation settling or shifting, indicating potential structural issues that should be evaluated by a professional to prevent further damage and ensure the stability of the building.

Exterior Foundation Wall Cracks

Signs of exterior foundation cracks include visible cracks on the exterior walls of the foundation, bulging or bowing walls, gaps between the foundation and the adjacent structure, and water seepage or pooling around the foundation perimeter. These signs indicate potential structural issues that require professional evaluation and repair to prevent further damage and ensure the stability of the building.

Leaning Chimney

A leaning chimney is a significant structural issue that often indicates foundation settlement or deterioration of support structures. It can pose serious safety risks and should be addressed promptly to prevent collapse or further damage to the building. Professional evaluation and repair are necessary to stabilize the chimney and ensure the safety of the structure.

Sagging Floors

Sagging floors are often a sign of underlying structural issues, such as inadequate support, foundation settlement, or deterioration of structural components. It is essential to address sagging floors promptly to prevent further damage and ensure the safety and stability of the building. Professional assessment and repair are necessary to identify the root cause and implement appropriate solutions.

Stair-Step Cracks in Brick & Walls

Stair-step cracks in bricks and walls indicate foundation settlement or structural movement, necessitating prompt attention to prevent further damage. Professional evaluation is recommended to address the underlying cause and implement necessary repairs.

“Honest, Reliable, and Great Work!”

Finally waterproofed after years of ignoring the problem. They did a solid job and didn't oversell extras. Happy with results.

⭐⭐⭐⭐⭐ Steve Jacobs — Google Review

I appreciated that they gave me a clear price upfront. Fixed some cracks in the foundation and added an interior drainage system. Basement’s drier than it’s been in years.

⭐⭐⭐⭐⭐ Ahmed Abouelfaid Elkhanboubi - Google Review

So we had this problem with water coming in during heavy rains. They came out, put in a sump pump and sealed up some cracks in the basement walls. Took a couple days but they were pretty quick. Price was fair too. The basement’s dry now, fingers crossed it stays that way.

Foundation Repair

Causes Of Foundation Damage

Expansive Soils

Expansive soils create foundation damage. Expansive soils, including, clay soil, shrink-swell, and heavable soil, are all different names for the same thing. Expansive soils are responsible for more damage to buildings than any other natural hazard.

This type of soil contains minerals like smectite clays, which absorb a lot of moisture. As the expansive soil soaks up water it expands – up to 15 times its dry volume. Furthermore, the expanded soil then pushes against your foundation and creates cracks or waterproofing problems.

In fact, as the expansive soil dries, it shrinks. The soil shrinkage gives your foundation room to move around. Consequently, this extra room removes the support from your foundation and will cause cracks, settling, and other foundation damage. The pressure of expansive soils against your foundation can exceed 30,000 pounds per square foot.

Deep Foundations

Deep foundations require a type of foundation repair that has support columns, pillars, or piles. These piers are driven deep into the ground or until they reach bedrock. This is done to provide additional stabilization when the surface soil can no longer support the weight of your home.

These types of foundations require solutions which address problems like settlement or stair-step cracked bricks. For example, if your home has cracked bricks caused by settlement, push piers or resistance piles may be installed. The piers are installed beneath your home’s foundation footing and then driven into bedrock or stable soil.

The piers are installed into stable soil or bedrock because it prevents further settlement and movement. Furthermore, the resistance provided by the stable soil can even help lift your home back to its original level.

Deep Foundation Soils

When the soil your home is built on can no longer support the weight of your home, the structure will start to settle. An expert may recommend installing a deep foundation system to stabilize your home.

Deep foundation soils and deep foundation systems are best understood by starting with the ground. Soil is made up of obvious layers which have different qualities and are a good indicator of how deep you need to extend your foundation.

The top layers of soil compress and easily compact – this is where settlement occurs and where you’ll find problem soils like expansive clay. The deeper soil layers, like parent rock, are stable and less likely to move. This is why a deep foundation pier system is installed into competent load bearing soils or bedrock.

Improved Living Environment

Foundation cracks can let more moisture into your home, causing mold and mildew growth. A particularly toxic strain of mold, black mold, can be extremely harmful to people with respiratory issues. It can also cause allergies, and in some cases, asthma attacks. By repairing the cracks in your walls and making sure your foundation is stable and secure, you can literally breathe easier.

Foundation Repair F.A.Q

What is foundation repair?

Foundation repair involves stabilizing and restoring the structural integrity of a building's foundation to address issues such as settlement, cracks, bowing walls, or shifting. Left unaddressed, foundation problems worsen over time and can compromise the entire structure. DMV Waterproofing's civil-engineer-designed solutions are tailored to the specific soil conditions and foundation type of your home.

What are the signs that my foundation needs repair?

Common warning signs include: cracks in basement walls or floors, stair-step cracks in brick or block walls, bowing or leaning walls, doors and windows that stick or won't close properly, sagging or uneven floors, gaps between walls and ceilings, and a leaning chimney. If you notice any of these, a professional inspection is strongly recommended.

What causes foundation problems?

The most common causes are expansive soils (clay soils that expand when wet and shrink when dry), poor drainage around the foundation, plumbing leaks, tree root intrusion, and inadequate original construction. In the Maryland, Virginia, and DC area, expansive clay soils are the leading cause of foundation movement and cracking.

Can foundation problems be fixed?

Yes — most foundation problems are fully repairable. Common solutions include wall anchors and carbon fiber straps for bowing walls, helical or push piers for settlement, and crack injection for minor cracks. DMV Waterproofing's civil engineers assess each situation individually and recommend the most effective, long-lasting solution.

How long does foundation repair take?

Most foundation repair projects take 1–3 days depending on the scope of work. Simple crack repairs may be completed in a single day, while more extensive stabilization projects involving pier installation can take 2–5 days. DMV Waterproofing provides a clear timeline during your free inspection.

How much does foundation repair cost?

Foundation repair costs in Maryland, Virginia, and DC typically range from $2,000 to $25,000+, depending on the type and severity of the problem. Minor crack repairs start around $500–$2,000. Wall stabilization with carbon fiber straps runs $3,000–$8,000. Full pier systems for settlement can cost $10,000–$25,000+. DMV Waterproofing offers free written estimates and 0% APR financing through Wisetack.

Will foundation repair affect my home's value?

Yes — positively. A documented, professionally repaired foundation with a transferable lifetime warranty is a strong selling point. Unrepaired foundation issues are routinely flagged by home inspectors and can kill deals or significantly reduce offers. DMV Waterproofing's lifetime structural warranty transfers to new owners, making it a direct value-add at resale.
