Foundation Repair Estimate: What to Look For

Quick answer

A foundation repair estimate is a written statement from a contractor of what work they propose, with what materials and on what schedule, and what they will charge for it. A usable estimate describes the work in enough detail that two bids can be compared line by line.

An estimate is not a diagnosis. It sits downstream of someone deciding what is wrong, and it is only as good as that decision. We print no prices here, because cost depends on the house, the soil and the plan.

Quick facts

The key facts about Foundation Repair Estimate, with sources:

What it should list: A description of the work, the materials, a completion date and the price ¹
Number of estimates: The FTC advises getting several, and not choosing the lowest by default ¹
Contract basics: Contractor name, address, phone and license number; start and finish dates; total cost; payment schedule ¹²
Permit and engineer: Some cities require a permit and an engineer-sealed design for foundation repair ⁴
Warranty: Promises are enforceable only if written down, per Connecticut’s attorney general ³
Where costs are explained: The cost guide breaks down drivers; this page covers the document

Key takeaways

A written estimate should list the work, the materials, the completion date and the price ¹.
The lowest bid is not automatically the best. Ask why bids differ ¹.
Two estimates compare only if they describe the same scope, the same permit and engineering, and the same warranty terms.
Never sign with blank spaces, and never pay in full up front ¹².
Some cities require a permit and an engineer-sealed design. Ask whether the estimate includes both ⁴.
An estimate is not a diagnosis. For significant or changing movement, ask a licensed structural engineer first.

What a foundation repair estimate is

An estimate is a contractor’s written offer. It says what they plan to do and what it will cost. The words estimate, quote, bid and proposal are used loosely.

Some are priced offers you can accept, and some are rough numbers that can change. Ask which one you hold, and whether the price is fixed or can move.

The FTC says a written estimate should include a description of the work to be done, the materials, the completion date and the price ¹. If one of those four is missing, ask for it before you compare anything else.

This page is about the document. For the factors that move the numbers, use the foundation repair cost guide. For the work description that sits inside it, see foundation repair scope of work.

General information, not a diagnosis of your house

General information, not a diagnosis of your house. This page prints no prices and does not say what repair your house needs. That decision comes from an assessment of the cause.

How an estimate is built

Most estimates stack several pieces. There is the work itself, such as piers, wall support, drainage or slab lifting. There are materials and equipment. There is labor and travel.

There are engineering, permits and inspections where the city requires them. There is site restoration, such as patching drywall or replacing soil and plants. There may be a warranty and a payment schedule.

The pieces matter because estimates differ in what they include. One bid might price only the piers. Another might add the engineer’s report, the permit and the restoration. Put side by side, the first looks cheaper and may not be.

FEMA’s manual on retrofitting existing houses shows the same logic from the engineering side: the designer examines the existing foundation’s capacity against expected loads before deciding what must be added ⁵. A good estimate follows from that kind of check, not the other way around.

What should be listed, line by line

A checklist of lines, not a price list. The scope guide goes deeper on the work description.
Line	What it should say	Why to ask
Work description	What will be done, where and with what method ¹	A vague line cannot be compared or enforced
Materials	What goes into the work ¹	Substitutions change what you bought
Schedule	Start and estimated completion dates ¹²	Dates are the basis for any later dispute
Price and payment schedule	Total cost, plus the down payment and later payments ²	Shows when your money is at risk
Engineer and permit	Whether the price includes engineering, permit and inspection ⁴	Some cities require them; others may not
Warranty	What is covered, for how long and who stands behind it, in writing ³	Connecticut says warranty promises are enforceable only in writing ³
Contractor identity	Name, address, phone number and license number ¹	Needed to check licensing and complaints
Change handling	How extra work is priced and approved	Open-ended terms invite surprises

Example: two estimates that look alike and are not

An illustration with no numbers. Two contractors price the same house. The table shows how the documents can differ even when both say “foundation repair.”

Line	Estimate A	Estimate B
Work	Lists the method and locations in general terms	Lists the method, the number of units and a plan sheet reference
Engineering	Not mentioned	Includes an engineer’s design and a letter after the work
Permit	Owner to obtain	Contractor obtains, owner confirms with the city
Restoration	Not mentioned	Interior and landscape patching listed
Warranty	Verbal	Written, with terms and exclusions
Payment	Large deposit before work	Payments tied to stages

A is not necessarily cheaper than B once the missing lines are added. Ask A to fill the gaps in writing, and ask both to price the same plan. Connecticut’s attorney general notes that the responsibility for permits ultimately rests with the homeowner, so confirm permits with your local officials either way ³.

Where estimates come from and who writes them

Estimates come from repair contractors after a site visit. Some firms offer a free visit as part of the sales process.

Illinois’ attorney general lists people who offer to inspect your home for free among the warning signs of repair fraud ², which is a reason to treat any free inspection as a sales step and not as an independent finding.

An independent assessment is a different thing. A licensed structural engineer who does not sell repairs can say what is wrong and write the scope that contractors then price. See structural assessment vs. foundation inspection and do I need a structural engineer.

Some cities require the engineer. The City of Mesquite, Texas, wrote in 2006 that foundation repairs there are done under a licensed engineer’s design and that the permit is finaled once the engineer’s letter approving the repairs arrives ⁴. That is one city’s rule. Ask your building department.

What a detailed estimate gives you

What a good estimate does

Lets you compare bids on the same scope instead of on a headline number ¹.
Puts promises in writing, which matters because Connecticut’s attorney general says warranty promises are enforceable only if written ³.
Shows what is and is not included: engineering, permits, restoration.
Gives you dates and a payment schedule you can hold the contractor to ².

What it cannot do

Cannot prove the diagnosis is right. A contractor’s estimate prices their proposed method.
Cannot guarantee the repair stops all future movement. Soil, water and loads still act on the house.
Cannot replace an engineer’s plan where one is required ⁴.
Cannot protect you if you sign with blank spaces or under pressure ¹².

Limits of an estimate

Two things limit every estimate. The first is what the contractor can see. Foundations are mostly underground and behind finishes, so an estimate is written from partial information. The scope can grow if conditions differ from what was expected, which is why the change terms in the contract matter.

The second is who is pricing. A contractor prices the method they sell. A piering firm prices piers. A drainage firm prices drainage. None of them is neutral about which method your house needs.

For that reason, an engineer’s scope is a better basis for comparing bids than a sales visit. See foundation repair second opinion for how to get one.

Finally, a lower price can come from leaving out lines. Compare scope first and price second.

Engineer first, then price

If movement is significant, widening or changing, get a licensed structural engineer’s assessment before collecting prices. Then ask each contractor to price that plan.

What moves an estimate (no prices here)

We do not print prices or an average. Cost depends on the cause, the method, the number of locations, access, soil, depth, engineering, permits, site restoration, the warranty offered and local labor.

The cost guide explains each driver in plain terms. Use the cost calculator to test how scope changes the picture, and the pier count estimator to sanity-check the number of supports in a bid.

When a bid is far from the others, the FTC suggests asking for an explanation of the difference ¹. Often the reason is a line that one bidder left out. Ask each bidder for the unit counts and scope in writing so you can see why.

A warranty is part of the price too. See foundation repair warranties for what to look for.

How to compare estimates

A step-by-step way to line bids up. It does not name a winner.

Get several, in writing: The FTC advises collecting multiple written estimates and not defaulting to the lowest ¹.
Give each the same facts: Share the same engineer’s report or the same description of what you see.
Line up the scope: Put each bid’s work, units, materials, engineering, permit and restoration lines in a table.
Mark the gaps: Ask each bidder to fill any missing line in writing.
Compare terms: Check payment schedule, dates, change handling and warranty wording ²³.
Check the company: Verify the license with your state or county and ask for proof of insurance ¹. Connecticut’s attorney general also suggests asking for references from similar jobs ³.

Protecting yourself while you collect estimates

Habits that keep you in control of the process.

Keep every estimate, email and photo in one folder with dates.
Do not sign a contract with blank spaces or one you have not fully read ¹².
Do not pay the full amount up front. The FTC notes some states limit how large a down payment can be ¹.
Do not sign a certificate of completion or make final payment until the work is done to your satisfaction and approved by local building officials when needed ²³.
Ask for lien waivers from subcontractors and suppliers before final payment, as Connecticut’s attorney general advises ³.
If you plan to claim insurance, read the policy first. Insurance coverage depends on the policy wording and cause. See our insurance guide.

Risks and when to call a structural engineer

The risks around estimates are paying for the wrong repair, paying before work is permitted, and signing under pressure. The FTC lists pressure to decide at once and demands for cash or full payment up front among the warning signs ¹.

Illinois’ attorney general adds contractors who offer to drive you to the bank, or who ask for payment to a person other than the company ². See foundation repair red flags.

A price is not a diagnosis. Movement history, displacement, water, construction details and soil change what cracks and slopes mean, and no one can read a house from a photo.

Call a licensed structural engineer if movement is significant, widening or changing; if walls bow or are displaced; if doors and windows stick along with new cracks; if corners separate; or if you have any safety doubt. Our contractor guide and the engineer or contractor tool help you decide who to call first.

Do not start work or dig before the plan is set

Digging beside a foundation, jacking a house or removing support before an engineered plan and a permit are in place can cause damage that is hard to undo.

Contract and permit rules that touch an estimate

Estimates become contracts, and contracts are governed by state law. Connecticut requires a written contract with signing, start, completion and cancellation dates and a right to cancel within three business days ³.

Illinois lists basic contract terms and gives consumers three business days to cancel a sale made at home, with longer periods for some older homeowners and for insurance-denied claims ².

The FTC says a contract signed at home or away from the seller’s permanent place of business should include a written statement of the right to cancel within three business days ¹. Your state may differ.

Permits and engineer rules are local. Mesquite’s 2006 policy letter says all foundation repair work there requires a permit before work starts, with an engineer-sealed design in the submittal ⁴. See foundation design and building codes for how adoption varies. Licensing rules for contractors also vary; see credentials and licensing.

Check your own state and city

The rules above come from Connecticut, Illinois, the FTC and one Texas city, and are shown as examples. This is education, not legal advice. Ask your state consumer-protection office and building department.

Estimate compared with nearby documents

Document	What it is	How it differs
Estimate	A contractor’s written description of work and price ¹	This page; may or may not be binding
Scope of work	The detailed list of what will be done	It sits inside the estimate or contract
Contract	The signed agreement with terms, dates and payments ²	Legally binding once signed
Engineer’s report	An independent assessment and plan	Can be the basis for comparing estimates
Warranty	The written promise about the work ³	Terms differ by company and by what is excluded

Estimate myths

Myth The lowest estimate is the best deal.: Reality The FTC says not to choose the lowest bid automatically and to ask why bids differ ¹.
Myth A free inspection is an independent diagnosis.: Reality It is usually a sales visit. Illinois’ attorney general lists offers of free inspections among warning signs of repair fraud ².
Myth A verbal promise is as good as a written one.: Reality Connecticut’s attorney general says warranty promises are enforceable only if in writing ³.
Myth An estimate includes the permit and engineer.: Reality Not always. Ask, because some cities require both ⁴.
Myth A bigger deposit shows a serious contractor.: Reality The FTC says not to pay the full amount up front and that some states limit down payments ¹.

Regional factors for estimates

Rules and conditions differ by place. Contractor licensing, contract content and cancellation rights are set by each state, as Connecticut’s and Illinois’ attorney general guidance show ³².

Permits and engineer requirements are set by each city, as Mesquite’s policy shows ⁴. Soil and climate also change the scope: swelling clay, high water tables or frost can add drainage and design work. Ask your state consumer-protection office and your building department what applies.

What to do with this

Before you collect prices, record what you see. The crack identification tool helps you log it, and the inspection checklist shows what a visit should cover. Then ask each bidder the questions in questions for a foundation repair company and keep every answer in writing.

Decision guide Estimate decisions by situation

If Movement is minor and stable so far: Then Photograph and date it; consider a monitoring log before collecting bids
If Movement is significant, widening or changing: Then Get a licensed structural engineer’s assessment, then ask contractors to price the plan
If Two bids differ widely: Then Ask both to list scope, units, engineering, permit and warranty in the same format
If A contractor pressures you to sign today: Then Walk away; the FTC lists pressure to decide at once as a red flag

Questions about Foundation Repair Estimate

What should a foundation repair estimate include?

At least a description of the work, the materials, a completion date and the price, per the FTC ¹. Also ask for the contractor’s name, address, phone and license number, the payment schedule, whether engineering and permits are included, the restoration work and the warranty in writing.

How many estimates should I get?

Several. The FTC advises getting multiple written estimates and not choosing the lowest by default ¹. If you need a plan, get an engineer’s assessment first so each bidder prices the same scope.

Why do foundation repair estimates differ so much?

Because the scope, method, unit counts, engineering, permits, restoration and warranty can all differ. A bid may also leave out lines the others include. The FTC suggests asking each bidder to explain the difference ¹. Put the bids in a table to find the gaps.

Is a free estimate really free?

The visit may cost nothing, but it is usually a sales step. Illinois’ attorney general lists offers to inspect your home for free among the warning signs of repair fraud ². Treat the visit as information, and for an independent view hire a licensed structural engineer.

Should the estimate include a permit and an engineer?

Ask. Some cities require both. The City of Mesquite, Texas, required a permit and an engineer-sealed design for foundation repair in its 2006 policy letter ⁴. Your city may differ. If the estimate leaves them out, ask who pays and who arranges them.

Can I negotiate a foundation repair estimate?

You can ask questions about scope and terms, and compare bids on equal footing. Be careful with large discounts for signing the same day, which the FTC lists as pressure ¹. Negotiate in writing and make sure the final contract matches.

How much deposit is normal?

It varies by state and contract, and we print no figures. The FTC says not to pay the full amount up front, and that some states limit how large a down payment can be ¹. Ask your state consumer-protection office. Tie later payments to stages of work.

What if the price changes after work starts?

It can, if conditions differ from what was expected. The contract should say how extra work is priced and approved, in writing. Illinois’ list of basic terms includes a payment schedule and grounds for termination ². Do not agree to open-ended changes.

Does my insurance pay for the repair estimate?

Coverage depends on policy wording, exclusions, the cause of the damage and state law. We cannot say whether yours pays. Read your policy and talk to your insurer. The Illinois guidance notes special cancellation rights tied to insurance claims ².
