Frequently Asked Questions

What Gets Inspected

An evaluation may look at piers or posts, beams, joists, connections, bearing points, shims, damaged wood and visible moisture. Access limitations should be disclosed.

Support Versus Framing Problems

A low floor can result from a support that moved, a beam or joist that deteriorated or deflected, inadequate bearing, or a combination. The repair should name the component rather than promise generic leveling.

Planning Work In A Crawl Space

Ask how access, debris, insulation, utilities, moisture, temporary support, new structural components and cleanup will be handled. Unsafe crawl spaces should not be entered by homeowners merely to inspect them.

From Concern To A Repair Decision

Use the visible symptom as the starting point, not the diagnosis. A useful path is to document what you see, identify the foundation system and affected area, request an evaluation, understand the proposed repair objective, compare the written scope, and only then authorize work. Foundation Repair Squad can help you check local service availability and request a free, no-obligation estimate.

Frequently Asked Questions

Can extra posts fix a sagging floor?

Additional support may be appropriate in some designs, but the cause and load path should be evaluated before adding supports.

Does moisture matter?

Yes. Persistent moisture can contribute to material deterioration and should be evaluated separately from structural support.

What should an estimate show?

It should identify locations, components, quantities, materials, access, structural objective and restoration or cleanup.

What A Complete Service Proposal Should Include

A useful foundation repair proposal identifies the observed condition, affected area, proposed work, quantities where relevant, materials or system, access, excavation, cleanup, restoration, schedule, price, payment terms, exclusions and warranty. If permits, engineering, plumbing, drainage or another trade may be involved, responsibility should be clear.

Before The Appointment

Gather previous foundation reports, repair invoices, warranties, engineering documents and photographs if you have them. Note when symptoms appeared and whether they changed. Make safe areas accessible, but do not enter unstable crawl spaces, excavations or other hazardous locations simply to prepare for an estimate.

During The Evaluation

Ask the professional to show or explain the observations and measurements behind the recommendation. If a branded system is proposed, focus on why it fits the property, where it will be installed and what outcome is expected rather than relying on product claims alone.

After Work Is Complete

Keep the signed contract, changes, final invoice, photos, permits or engineering documents when applicable, installation records and written warranty. Ask about project-specific maintenance or monitoring and the process for future warranty service.

Before You Authorize Foundation Work

Ask for the recommendation in plain language: what condition was observed, what part of the structure is affected, what the proposed work is intended to accomplish, and what evidence supports the recommendation. If the explanation depends mainly on a product name or a limited-time sales offer, request the underlying scope and findings before deciding.

Confirm who will perform the work and who will be responsible for the contract and warranty. Review applicable credentials, insurance, permits or professional documents for the project and jurisdiction. Clarify access, excavation, protection of the home, cleanup, restoration, payment milestones, change orders and what happens if conditions differ from the original assumptions.

Keep copies of the evaluation, written proposal, signed contract, approved changes, photos, final invoice, permits or engineering documents when applicable, installation records and warranty. These records make future service, remodeling and property transactions easier to understand.
