Question 1

Why are my three foundation repair quotes so far apart?

Accepted Answer

Because they are usually not quoting the same job. One is pricing piers to bedrock, one is pricing foam or mudjacking to lift the slab, and one is pricing cosmetic crack sealing. Homeowners routinely report a $2,500 bid and a $13,000 bid on the same house. Ask each bidder for the method, the number of piers or injection points, the target lift in inches, and the warranty term. When those four are on paper, the spread usually explains itself, and the outlier is visible.

Question 2

Piering or mudjacking, which one do I actually need?

Accepted Answer

It depends on what moved and why. Mudjacking and polyurethane foam lift a slab that has settled over voided soil, which is the common case after a removed tree's roots rot out or fill consolidates. Piers transfer the load to stable soil or bedrock and are for a structure that is still moving. Lifting a slab that is still settling buys you a year. Piering a one-time void is money spent on the wrong problem. The diagnosis should name the cause before it names the method.

Question 3

Should I fix foundation settling now or wait and monitor?

Accepted Answer

Sticking doors, cracked grout, and a patio door pulling away from the frame are movement, not cosmetics. Waiting is only defensible when the movement is documented as stopped, which means measured elevations at two points in time, not a memory of what the crack looked like last spring. The cost curve is the reason people say do not wait: repairs that start in the low thousands become five figures once the movement reaches framing, plumbing, or the sill plate.

Question 4

Will homeowners insurance cover foundation or water damage?

Accepted Answer

Usually not, and the reason is consistent: policies cover sudden events, not gradual deterioration. A slow plumbing leak that shifts a slab over years, or seepage that has been happening every heavy rain, typically reads as maintenance to the adjuster. The exceptions worth pursuing are a documented sudden failure and, sometimes, the cost of accessing the failed pipe. Get the cause documented in writing at the time of diagnosis, because the cause is what decides the claim.
