Before requesting estimates
Good intake information saves everyone a pointless truck roll. Photograph the whole surface and the problem details, note the address and access, and describe water flow, known leaks, utilities, roots, or prior repairs.
- Wide photos showing all connected slabs
- Close photos of transitions, cracks, joints, and slab edges
- Approximate dimensions and number of affected panels
- Photos after rain when ponding or runoff is part of the problem
- Known utility, pool, irrigation, foundation, or access constraints
Before accepting a proposal
Confirm the legal business name and who will perform the work. Request documentation appropriate to the project and verify it with the issuer when material. Do not rely on a badge copied onto a landing page.

- Exclusions, change-order conditions, payment schedule, and cancellation terms
- Warranty coverage, exclusions, duration, transferability, and claim process
After the work
Save the signed scope, invoice, measurements, photos, material information, use instructions, and warranty. Monitor drainage and follow any owner-maintenance requirements.
Related questions
Should I choose the longest warranty?
Read what the warranty covers and excludes, who stands behind it, and what remedy is offered. Duration alone can be decorative.
How many estimates should I get?
Enough to compare credible methods and scopes. More bids do not help when none describe the work clearly.
What records matter most?
The signed scope, provider identity, payment record, before-and-after photos or measurements, material information, and warranty are the core file.
