Have you noticed a growing gap between your concrete steps and the foundation of your home? You’re not alone. Concrete steps pulling away from the house is a common concern for homeowners—and one that shouldn’t be ignored. Whether you’re seeing cracks, sinking, or complete separation, the issue could signal underlying foundation problems or simply normal wear over time.
The good news? There are solutions—both DIY-friendly and professional.
In this post, we’ll walk you through why it happens, how to assess the severity, and the best ways to fix the concrete steps pulling away from your house.
Why Are Your Concrete Steps Pulling Away from the House?
Concrete steps pulling away from your house often result from underlying issues like soil movement or poor construction. These problems create gaps, cracks, or sinking steps, which can worsen over time if ignored. Below are the 3 main reasons why this happens, with clear explanations to help homeowners and property managers identify the cause.
Understanding Foundation Settlement
Foundation settlement occurs when the soil beneath your steps or house shifts, causing the concrete to sink or tilt. Loose or poorly compacted soil fails to support the steps’ weight. Erosion from heavy rain or expansive soils, like clay, that swell and shrink with moisture changes, can also contribute. Look for signs like uneven steps, gaps between the steps and the house, or visible foundation cracks. The American Society of Civil Engineers noted that 60% of homes over 30 years old experience some degree of settlement-related issues.
Common Causes of Step Separation
Several factors can lead to concrete stairs separating from your home. Poor initial construction, such as missing footings or rebar, weakens the steps’ stability. Water damage from clogged gutters or poor drainage erodes the soil beneath, creating voids. In colder climates, freeze-thaw cycles cause the ground to expand and contract, pushing steps away. Tree roots growing near the steps can also lift or shift the concrete. Each of these issues—construction flaws, water, frost, or roots—can create noticeable gaps or tilting.
Structural Issues with Steps
Not all step separation is cosmetic. Some cases involve serious structural problems. Steps may not be properly anchored to the house’s foundation, allowing them to move independently. Large gaps, tilting steps, or cracks in the adjacent foundation wall suggest deeper issues.
For example, if the house’s foundation itself is settling, the steps may follow. A structural engineer can assess whether the problem is limited to the steps or part of a larger foundation issue. Addressing these early prevents costly repairs, with foundation fixes averaging $2,500-$10,000 depending on severity.
Assessing the Damage: Is It a DIY Fix or a Professional Job?
Before fixing concrete steps pulling away from your house, evaluate the damage to decide if it’s a DIY project or requires a professional. Minor gaps or cracks can often be handled with basic tools, while severe issues like large tilts or foundation cracks need expert intervention.
Signs You Can Fix It Yourself
Small issues with concrete steps are often manageable for DIY enthusiasts with basic masonry skills. These repairs save money, typically costing $10-$200, compared to professional fixes. Look for these signs to determine if a DIY approach is suitable:
- Gaps between steps and house are less than 1-2 inches wide.
- Steps show minor settling with no significant tilting or sinking.
- Cracks in the steps are small, less than 1/4 inch wide, and not spreading.
- No visible damage to the house’s foundation or nearby walls.
Basic tools like a caulk gun, concrete patching compound, and a trowel are usually enough for these fixes. Home improvement stores like Home Depot carry products such as Quikrete for these repairs.
When to Call a Professional
Severe step separation or structural issues require professional expertise to ensure safety and long-term stability. Hiring a contractor or structural engineer prevents further damage, which can cost $500-$5,000 to repair. Contact a professional if you notice these signs:
- Gaps exceed 2 inches or steps are visibly tilting.
- Steps have sunk more than 2 inches or feel unstable when walked on.
- Cracks in the steps or nearby foundation are wider than 1/4 inch.
- House foundation shows signs of settlement, like wall cracks or uneven floors.
Professionals use advanced techniques like mudjacking or helical piers, which require specialized equipment. The Angi indicates that 70% of homeowners with foundation issues hire professionals to avoid escalating repair costs.
Safety Considerations
Ignoring concrete step separation creates safety hazards and risks further structural damage. Unstable steps can cause trips or falls, leading to injuries. The U.S. Consumer Product Safety Commission reports that stair-related injuries account for over 1 million emergency room visits annually. Stabilize steps before repairs by limiting use or adding temporary supports like wooden braces. Compare DIY and professional approaches in the table below to prioritize safety and effectiveness.

DIY Solutions for Fixing Concrete Steps Pulling Away
Homeowners and DIY enthusiasts can address minor concrete step separation with straightforward methods. These solutions fix small gaps, minor cracks, and slight settling, costing $10-$200 compared to professional repairs of $500-$5,000. The following 3 approaches suit gaps under 2 inches or minor settling, but ensure steps are stable before starting to avoid safety risks.
Filling Small Gaps Between Steps and the House
Gaps less than 1 inch between concrete steps and the house can be sealed to block water and halt further separation. This repair, costing $10-$50, improves appearance and stability. You need polyurethane caulk (like Sikaflex or Quikrete), a caulk gun, a wire brush, and a putty knife. For gaps over 1/4 inch, a backer rod reduces caulk use.
Clean the gap with a wire brush and water, ensuring it’s dry for adhesion. Insert a backer rod if needed, then apply caulk evenly with a caulk gun. Smooth it with a putty knife for a neat finish. Allow 24-48 hours for curing, per product instructions.
Repairing Minor Cracks in Steps
Cracks under 1/4 inch wide in concrete steps can be fixed to restore strength and prevent spreading. This repair costs $20-$100 and suits cosmetic or minor structural issues. Gather a concrete patching compound (like Quikrete Concrete Repair), a chisel, a trowel, and protective gear like gloves and safety glasses.
Use a wire brush to clean the crack, then rinse and dry it. Widen the crack slightly with a chisel to create a V-shape for better adhesion. Apply the patching compound with a trowel, pressing it in firmly. Smooth the surface and let it cure for 24-72 hours, following product guidelines. Seal repaired cracks every 1-2 years to protect against moisture.
Releveling Slightly Sunken Steps
Steps sunken 1-2 inches due to minor settling can be lifted with DIY mudjacking, costing $50-$200. This method requires a drill with a 5/8-inch masonry bit, a concrete slurry mix, a pump or funnel, and a level. Drill 1-2 small holes into the step’s surface. Mix cement, sand, and water into a thick slurry.
Pump or pour the slurry into the holes to fill voids beneath. Check the step’s alignment with a level, stopping when it’s even with the house. Fill holes with patching compound and smooth the surface. Allow 48 hours for curing. This method works only for minor settling and stable soil. It’s not suitable for major structural damage.
Professional Solutions for Severe Step Separation
Severe concrete step separation, such as large gaps or significant tilting, often requires professional expertise to ensure safety and durability. These issues, caused by foundation settlement or structural flaws, can cost $500-$5,000 to repair, depending on the method and damage extent. Professionals use specialized equipment and techniques to address problems beyond DIY fixes. Below are 4 professional solutions to restore concrete steps pulling away from your house, with details on processes, costs, and benefits.
Mudjacking for Settling Concrete Steps
Mudjacking lifts sunken concrete steps by injecting a slurry beneath them. This method suits steps that have settled 2-4 inches due to soil erosion or poor compaction. It’s cost-effective and minimally invasive, preserving existing steps.
How Mudjacking Works
A contractor drills small holes (1-2 inches) into the step’s surface. A slurry of cement, sand, and water is pumped through these holes to fill voids and raise the steps. The process takes 1-2 days, with curing complete in 24-48 hours. According to HomeGuide notes mudjacking restores 80% of sunken concrete surfaces effectively.
Benefits and Costs
Mudjacking costs $500-$1,500, depending on step size and region. It’s faster than replacement and requires no demolition. However, it’s less effective for steps with major structural damage or unstable soil, where deeper solutions are needed.
Helical Piers or Push Piers
For severe foundation settlement or steps sunken over 4 inches, helical or push piers provide a long-term solution. These steel supports stabilize and lift steps by anchoring them to stable soil or bedrock.
Installation Process
Contractors excavate around the steps to access the foundation. Helical piers, with screw-like blades, are driven deep into the ground using hydraulic equipment. Push piers are inserted vertically to reach stable soil. Both lift the steps back to level. Installation takes 2-5 days, depending on soil conditions.
Benefits and Costs
Piers cost $1,000-$3,000 per unit, with most projects requiring 2-4 piers. They prevent future settling and are ideal for homes in areas with expansive clay soils, like parts of Texas or California. The Angie’s List survey found 90% of pier installations last over 20 years.
Replacing Concrete Steps
When steps are severely damaged or improperly constructed, replacement is often the best option. This method ensures new steps meet modern building standards with proper footings and reinforcement.
Replacement Process
The old steps are demolished using jackhammers or heavy machinery. Contractors install deep footings and rebar for stability, then pour new concrete. Curing takes 7-14 days before use. This process addresses both cosmetic and structural issues, ensuring a level connection to the house.
Benefits and Costs
Replacement costs $2,000-$5,000, based on step size and local labor rates. It’s more expensive but provides a permanent fix, especially for steps with large cracks or poor initial construction. New steps can also enhance curb appeal, increasing home value by up to 2%.
Addressing Foundation Crack Repair
If step separation is tied to house foundation issues, repairing foundation cracks is critical. This method prevents further damage to both steps and the home’s structure.
Repair Techniques
Contractors may use epoxy injections to fill and seal foundation cracks, restoring strength. For larger issues, carbon fiber straps or wall anchors stabilize walls. A structural engineer often assesses the damage to recommend the best approach. Repairs take 1-3 days, depending on severity.
Benefits and Costs
Foundation crack repairs cost $500-$2,500, with complex cases reaching $10,000 if extensive stabilization is needed. Addressing foundation issues early prevents step separation from recurring and protects the home’s structural integrity. Neglecting foundation problems can lead to repair costs 50% higher over time.
