Cracks in foundation walls, uneven floors, sticking doors, bowed walls, and other signs of movement can all point to foundation problems, but they do not always have the same cause. Our team at DESKA Foundation Repair evaluates the structure and surrounding conditions to determine what is moving, why it may be happening, and which type of repair makes sense for the property.
We provide residential foundation repair throughout Northern Virginia, Washington, D.C., and Maryland. Our team combines foundation repair and structural contracting experience with licensed engineering support, allowing us to evaluate a wide range of foundation and structural concerns instead of approaching every problem with the same repair system.
Signs Your Home May Need Foundation Repair
Foundation problems often develop gradually, and the first signs may appear somewhere other than the foundation itself. Changes in walls, floors, doors, windows, or exterior masonry can sometimes indicate movement below the home.
Some common signs our team evaluates include:
- Cracks in foundation or basement walls
- Stair-step cracks through brick or masonry
- Bowing or leaning foundation walls
- Uneven or sloping floors
- Doors and windows that begin sticking
- Gaps around windows, doors, walls, or trim
- Cracks that continue to grow or reopen after repair
- Sagging floors or movement in structural supports
- Visible foundation settlement
- Structural concerns found during a home inspection
Not every crack or uneven floor means a home needs major foundation repair. The pattern, location, direction of movement, construction of the home, and surrounding conditions all help determine what may be happening.
Our Foundation Repair Services
Foundation repair can involve several different parts of a home’s structure. Our team provides solutions for settlement, foundation wall movement, cracking, damaged structural supports, and other conditions that can affect the stability of a home.
Foundation Settlement Repair
Foundation settlement occurs when part of the foundation moves downward or settles differently from another part of the structure. This movement can lead to stair-step cracks, uneven floors, gaps around openings, and other visible changes throughout the home.
Our foundation settlement repair services include underpinning and stabilization options based on the amount of movement, foundation construction, and conditions beneath the home.
Bowed Foundation Wall Repair
Foundation walls can bow, lean, tip, or move inward when pressure builds against the outside of the wall. Cracking may appear horizontally, diagonally, or near corners depending on how the wall is moving.
Our bowed wall repair services may include wall anchors, structural reinforcement, carbon fiber, or other repair methods selected for the condition of the wall.
Foundation Crack Repair
A foundation crack can be structural, a pathway for water, or sometimes both. Our team evaluates the crack and surrounding foundation before determining whether crack repair alone is appropriate or whether the movement or moisture problem behind it also needs to be addressed.
For stable poured-concrete cracks, epoxy crack injection may be one repair option.
Carbon Fiber & Wall Reinforcement
Carbon fiber can be used to reinforce certain foundation walls when the type and amount of movement make it an appropriate solution. It is one of several methods our team may consider when evaluating foundation wall problems.
Learn more about our carbon fiber wall reinforcement services.
Sagging Floors, Joists & Support Beams
An uneven or sagging floor does not always mean the foundation itself is settling. Problems with floor joists, beams, supports, crawl spaces, or other structural components can create similar symptoms.
Our team also provides floor joist repair and support beam repair when the problem is within the structure above the foundation.
Structural Evaluations
Some structural concerns need to be evaluated before the right repair can be determined. Our licensed engineers perform residential structural evaluations for foundation problems, renovation projects, inspection findings, load-bearing components, and other conditions where the cause or severity of the problem needs to be established.
How We Determine What Is Causing a Foundation Problem
The visible symptom is only part of the diagnosis. Two homes can have cracks that look similar while requiring completely different repairs.
When evaluating foundation concerns, our team looks at how the structure is moving and what conditions may be contributing to that movement. Depending on the property, this can include the crack pattern, direction of wall movement, floor conditions, foundation construction, framing, exterior drainage, moisture, surrounding grade, and evidence of previous repairs.
This is also why we do not assume that every foundation crack requires underpinning or structural stabilization. In some cases, the issue may be limited to a stable crack. In others, drainage, wall movement, settlement, or structural framing may need to be addressed before a lasting repair can be recommended.
What Causes Foundation Problems?
Foundation movement can develop for several reasons, and more than one condition may be involved at the same property.
Soil and Foundation Settlement
Changes in the soil beneath a foundation can affect how well it supports the structure. Settlement can occur when soil compresses, erodes, changes with moisture conditions, or does not provide consistent support beneath the footing.
Pressure Against Foundation Walls
Soil and water outside a basement or foundation wall can place lateral pressure against the structure. Over time, this pressure may contribute to bowing, leaning, cracking, or other wall movement.
Structural Framing Problems
Some symptoms that homeowners associate with foundation movement actually begin in the framing above it. Damaged joists, inadequate supports, deteriorated beams, or crawl space conditions can all contribute to sagging or uneven floors.
Drainage and Water Around the Foundation
Water that collects around a home can affect both the soil beneath the foundation and the pressure against foundation walls. Poor grading, downspout discharge, groundwater, or inadequate yard drainage may contribute to foundation and basement problems. You can learn more about our residential drainage solutions
Foundation Repair Options Depend on the Problem
There is no single foundation repair system that is right for every home. The appropriate solution depends on what part of the structure is moving, the direction and severity of that movement, and what is causing it.
Depending on what we find, foundation and structural repairs may include:
- Foundation underpinning
- Helical or resistance piers
- Wall anchors
- Carbon fiber reinforcement
- Structural wall bracing
- Foundation crack injection
- Joist or beam reinforcement
- Drainage improvements
- Basement waterproofing
- Other structural repairs based on the condition of the home
Our goal is to recommend the repair that addresses the actual problem. Not every crack requires structural stabilization, and not every settling foundation requires the same type or amount of underpinning.
Foundation Conditions in Northern Virginia
Homes throughout Northern Virginia can be built on very different soil and site conditions. Parts of Fairfax County contain expansive or low-bearing soils, while other properties may be affected by disturbed soil, drainage conditions, slopes, groundwater, or changes in moisture around the foundation.
These conditions can vary considerably from one property to another, even within the same community. Our team evaluates the individual home and site rather than assuming that every foundation problem in Northern Virginia has the same cause.
We provide foundation repair services from our offices serving Alexandria, Mount Vernon, Herndon, and Bethesda, along with surrounding communities throughout the greater Washington, D.C. region.
Frequently Asked Questions About Foundation Repair
What Affects the Cost of Foundation Repair?
The cost of foundation repair depends heavily on what is causing the problem and what is required to correct it. A limited crack repair is very different from stabilizing a settling section of foundation or reinforcing a foundation wall.
Factors that can affect the scope and cost of a project include the type and amount of movement, foundation construction, repair method, number and depth of piers, length of affected walls, access, excavation requirements, drainage conditions, and whether other structural components also need repair. Our team evaluates these conditions before recommending a repair and preparing the appropriate scope of work.
How do I know if I need foundation repair?
Cracks, uneven floors, sticking doors, bowed walls, and visible movement are reasons to have the structure evaluated, but they do not automatically mean major repair is necessary. The pattern and cause of the movement need to be determined before the appropriate repair can be recommended.
Are all foundation cracks structural?
No. Some cracks may be stable and primarily create a pathway for water, while others are associated with settlement or foundation wall movement. Our team evaluates the crack and surrounding structure to determine what type of repair may be appropriate.
What is the difference between foundation settlement and a bowed wall?
Foundation settlement generally involves downward movement of the footing or foundation. A bowed wall moves inward because of pressure against the side of the foundation. Although both conditions can produce cracking, they usually require different repair methods.
Can drainage problems affect my foundation?
Yes. Poor drainage can contribute to soil erosion, moisture changes around the footing, water pressure against foundation walls, and basement or crawl space moisture. Correcting drainage may be an important part of addressing the underlying problem.
When should I have a structural engineer evaluate my foundation?
A structural evaluation can be helpful when the cause or severity of the movement is unclear, when significant structural changes are involved, or when an independent engineering assessment is needed. Our team can help determine the appropriate type of evaluation based on the concern.
