Master the Basics of Your Home Foundation
There are 3 pieces of information that will help you make sense of house foundation quotes and recommendations.

What Kind of Foundation Do You Have?
Most American homes have 1 of 2 types of foundation: concrete slab foundation, or pier and beam foundation.
A slab foundation is a 4” - 6” thick layer of concrete poured over a drainage layer (usually gravel and/or sand). Your house is placed directly on top of the slab for stability and support.
Concrete slab foundations are common in new construction and homes built after 1980. If you don’t have a crawlspace, you likely have a concrete slab.
✅ Pros of Concrete Slab: A continuous concrete slab means consistent support in every area of your home — no sagging floorboards or “weak spots”. A well-installed slab foundation can last up to 200 years.
🚫Cons of Concrete Slab: Slab foundations perform poorly in flood-prone areas — the house sits directly on its slab, and there’s no space for excess water to drain.
Pier and Beam Foundation
A pier and beam foundation begins with a series of concrete and rebar beams driven into the bedrock underneath your soil. Beams are placed across piers to create a foundation support for flooring and joists.
If your home has a crawlspace, you almost always have a pier and beam foundation.
✅ Pros of Pier and Beam: Pier and beam foundations are ideal in areas that experience heavy flooding, and where the frost line is several feet underground. Additionally, plumbing work is typically less expensive on pier and beam homes due to easy access to the drain and supply lines.
🚫Cons of Pier and Beam: Common issues of pier and beam foundations include sagging floors and pooling water in your crawlspace.
How Your Soil Type Affects Your Home’s Foundation
Soil is primarily made up of 3 components:
Clay, which has poor water drainage.
Silt, which has average water drainage properties, and
Sand, which has excellent water drainage properties
The amount of sand, silt and clay in your region’s soil directly affects your home foundation.
Impact of clay soil on foundation repairs: Soil with high clay content expands and contracts which can cause shifts in your foundation. Look for cracks in your drywall or doors sticking to identify issues
Impact of silty soil on foundation repairs: Silty soil is marginally better than clay for building and repairing foundation, as it shifts less over-time. Look for water pooling around your foundation to determine if there are issues.
Impact of sandy soil on foundation repairs: The more sand is present in your soil, the better it drains — this means less pooled water around your foundation and less natural causes of flooding and foundation leaks.
Concrete slab foundations tend to do well in sandy soil. However, sandy soil (like sand on a beach) can wash away and erode over time. Be sure to check your foundation drop measurements every few years to ensure your soil isn’t washing away.
You can sell your house without fixing your foundation — but that doesn’t mean you should. Foundation issues are often negotiated between the buyer and seller, especially if it is called out in the inspection report.
Typically buyers have more control over cost, and can avoid time intensive negotiations and repairs if they address issues outside of closing.
Consult a real estate agent before you make this decision. Your agent will provide the best option for addressing any foundation damage prior to listing your home for sale.
How to Read a Foundation Inspection Report (Made Easy)
Now that you understand your foundation type and soil, how do you read your foundation report?
Here are the 3 most common items identified on Foundation reports:
Foundation settlement or drop
Baseline measurement (or set measuring point)
Piers, shims, and drains
What’s an Acceptable Level of Drop?
Foundation drop (or “settlement” as foundation companies refer to it) describes how much your house tilts from one end of the foundation to the other. Settling is a natural part of owning a house. Here’s why:
Soil compacts when weight is placed on top of it and houses are heavy. Most of the time this happens in a uniform way, but sometimes certain parts of the foundation settle more than other parts.
Foundation companies record “drop” in inches to see if your foundation is settling more than usual. Structural and foundation engineers consider 1 inch of drop for every 20 feet the maximum acceptable level of foundation drop. The numbers on your foundation inspection reflect how much drop or lift there is at that point from the “set measuring point.”
What is a Baseline Measurement (or Set Measuring Point)?
Most floors are not completely level, so it’s difficult to determine foundation movement with one measurement. Foundation companies will use an instrument, typically a high-precision altimeter, or laser level to take multiple measurements all across the house to see what’s changed.
In order to determine how much has changed, they choose an arbitrary point as the baseline and measure all other foundation settlement compared to that baseline. Compare the baseline to future foundation inspections to judge the rate your foundation is settling or shifting. That measurement is called the baseline measurement and is typically marked with a 0 on the inspection
This is where the numbers on your foundation report come from! For example:
+1.2 means that point has lifted 1.2” from the set measuring point
-0.4 means that point has dropped .4” from the set measuring point
PRO TIP: Check your home purchase documents for “As Built” foundation measurements — these reflect grade and slope when your house was originally built. They’ll give you a much larger picture of how your house has shifted over time.
What do all of the symbols mean?
Most companies will mark their recommendations for fixing a foundation on the inspection report. Here are the most common recommendations:
Piers - usually marked with dots, plus-signs, squares, or symbols - piers are used to raise low parts of the foundation
Shims - for pier and beam foundations, shims are used to address gaps between joists and piers - they’re typically marked with arrows
Drains - french drains are often called for in foundation inspections and will be drawn with a line to indicate direction, which downspouts they’ll connect to and any surface drains
Fans - some crawl spaces will need to be ventilated - fans are often not marked on the map of the house, but are typically described in the written portion of the report.
Beams - If your pier and beam house needs a new beam look for a double line and often written notes about length

Home Foundation Repair & Installation Prices
Now that you understand how to read a foundation report, it’s time to get some estimates on your project. Let’s look at current pricing data and average costs of residential foundation repair and foundation installation projects.
Foundation Inspection Costs by Home Size
The average home foundation inspection conducted by a structural engineer costs between $450 and $800. This figure reflects a general foundation inspection on a footprint less than 2,000 square feet.
If you experience extensive slab leaks or widespread foundation settling, expect to pay between $1,500 and $3,000 for these complex inspections.
Foundation Repair and Installation Costs by Foundation Type
HOMR researched current pricing data for pier and beam repairs, slab foundation repairs, and general drainage repairs in crawl space and basement areas.
Foundation Labor Costs
Expect to pay around $200 per hour for foundation repair labor. This is a national average, so be sure to get multiple quotes on the project to compare specific prices in your area.
Average Pier and Beam Foundation Costs by Material
Cost (Low end)
Cost (High End)
Cement (per yard)
Concrete Pier (per pier)
Hybrid Pier (per pier)
Steel Pier (per pier)
Shimming (per instance)
Pier and beam foundation repair costs are driven by one key factor - number of piers best calculated by individual materials — sizes and footage of pier and beam structures vary greatly, making square footage estimates unreliable.
Average Slab Foundation Repair Costs
Cost (Low end)
Cost (High end)
Minor cracks refer to small cracks in your concrete slab that travel several feet through the foundation. Major cracks refer to larger concrete slab cracks that impact at least ¼ of your home’s foundation.

Foundation Drainage Repairs
The cost of foundation drainage relies heavily on the type of drains and fans utilized to resolve your drainage issue. There are 2 kinds of drainage repair projects — exterior yard drainage systems, and if you live in areas with a basement - basement drainage
Average Exterior Drainage Costs
Cost (Low end)
Cost (High end)
French Drains (per linear ft)
Trench Drains (per linear ft)
Buried Downspouts (per downspout)
Catch Basins (per drain)
Storm Drainage System (installed)
The most popular exterior drainage solutions are French drains and trenches. French drains cost between $12 and $55 per linear foot, but complex installs may cost $95 to $100 per linear foot.
Trenches cost between $35 and $100 per linear foot, but complex installs can increase your cost per linear foot by 1.5x.
Average Basement Drainage Costs
Low Avg Cost
High Avg Cost
Interior French Drain
The 4 primary types of basement drainage solutions are sump pumps, curtain drains, basement waterproofing, and interior French drains.
Expect to pay between $4,000 and $13,000 for a complete basement drainage system.
The average residential foundation project takes between 1 and 3 days to complete. Complex foundation repair projects, like resolving a major slab leak or damaged ductwork in your crawlspace, may require up to a week or more to complete.
Once your initial plumbing and structural inspections are complete, here are estimated timelines to complete specific home foundation projects:
Pier installation to remediate foundation damage: 2-3 days
Crawl space mold remediation: 3-10 days (depending on mold severity)
Crawl space fan and air vent installation: 2 days (plus 1 to 2 follow-up visits)
Basement wall anchors: 1 day
Basement steel beam installation: 2 days
After these tasks are complete, be sure to schedule a post inspection with your plumber and structural engineer. This follow-up involves a repeat inspection of your repaired foundation, soil moisture level and ongoing monitoring of your foundation.
Obtaining a Foundation Work Permit
Foundation repair and installation always requires a building permit from your local building department. Your project’s timeline is highly dependent on how long it takes the building department to approve your permit for residential construction.
3 Things to Expect During Your Foundation Project
Your pre-project foundation inspections are complete, and it’s time for your foundation contractor to start work.
Here are 3 things to expect during your foundation repair project — 1 that will likely happen, a less-likely situation you should still prepare for, and 1 service every quality foundation company should provide.
Prepare for Tunnels in Your Yard
Your repair and remediation team must access your home’s foundation to make repairs to cracks, leaks and general damage. The simplest way to achieve this is by digging a path through your yard to the foundation — generally through a trench or tunnel.
Expect some of your yard and planting/garden areas to be compromised during this process. It’s inconvenient, but a direct trench to your foundation issue is the cheapest and least invasive way to resolve the problem.
Pro Tip: Make sure that all your plumbing and irrigation lines are clearly marked before the foundation contractors start digging. You’ll avoid any accidental damage to your exterior pipes — the last thing you need during foundation repair is another leak!
Uncommon, but Messy: Your House Might Get Lifted!
Don’t be surprised if contractors use hydraulic jacks and support cylinders to lift your home to access its foundation. House raising is a less common practice, but it’s a good solution in 3 severe cases:
Repairs to a badly cracked foundation wall
Repairs to a fully cracked concrete slab
Raising the basement height in a sinking house
Using hydraulic jacks to raise your home is never a DIY project. Expect to pay between $25-35 per square foot for a house raising project — it costs between $50,000-$70,000 to jack up a 2,000 square foot house.
Expect Quality Debris Removal After the Job
We expect every foundation repair service to perform quality debris removal after the job is finished. Cleaning up after yourself is part of professional service, not an “over the top” expectation.
Look for foundation contractors with excellent online service reviews that note their cleanliness and professionalism.

The 4-Step Plan to Long Term Foundation Success
Ensure your home’s foundation remains stable and secure for the long haul by adding these 4 items to your home foundation maintenance checklist:
Schedule a follow-up service appointment
Anticipate some foundation movement
Monitor soil moisture
Maintain good plumbing
Schedule a Follow-Up
Schedule a post project inspection with your structural engineer to ensure your foundation repair or installation was successful. This inspection should be identical to your initial inspection to ensure a proper data comparison with your pre-work baseline measurements.
Pro Tip: HOMR schedules this follow-up for you through our 24/7 home management concierge service.
Anticipate Some Foundation Movement
Every foundation job creates movement of the house. Common signs of mild foundation movement include minor cracks in your drywall and shifting of door frames. Don’t be surprised to see these things after a foundation repair.
Hold off on doing drywall repairs or re-shimming doors until at least 3-6 months after your foundation repair project is complete.
Monitor Drainage and Soil Moisture
Review your basement and external drainage after the repair is complete. Wait for significant rainfall, then check how your new drainage systems are operating.
Check any previous “trouble spots” in your yard for damp soil, pooled water and soggy turf. These issues should be resolved after your foundation repairs.
Maintain Regular Plumbing Inspections
Conduct annual plumbing inspections to ensure your pipes and drains are functioning properly. Your first inspection after foundation repairs should be handled by a certified master plumber, who can conduct water pressure tests on your pipe system.
Ask your master plumber to conduct a hydrostatic pressure test to ensure there’s no pressurized water impacting your foundation.
Conducting a hydrostatic pressure test is a great way to get homeowners’ insurance to approve your claim. Learn all 6 steps to getting insurance to cover your foundation claim in our new article.
