What is not part of foundation crack injection & sealing
Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.
- Any job where labor and materials together reach $1,000 or more is done by a licensed contractor, and NorTech flags it before you book.
- Diagnosis of the structural cause of a crack. A licensed engineer or licensed foundation contractor makes that call.
- Underpinning, piers, wall bracing, carbon fiber and other structural repairs. Those are licensed work and often need permits.
- Exterior excavation, waterproofing membranes and drain tile. See the waterproofing and drainage services.
- Mold remediation and interior finish repairs after a leak.
- Guarantees that a crack will not reopen or that a wall will stop moving.
License and permits for foundation crack injection & sealing
Cracks in a foundation can be harmless or can point to movement, and the work involved ranges from sealing to structural repair. Sealing is done by background-checked concrete pros, and structural repair is done by licensed contractors who hold the license, often after an engineer has evaluated the cause.
Sealing a stable crack may not need a permit. Structural repair, added reinforcement, underpinning and excavation along a foundation commonly do, and some areas require an engineer letter first. Your pro explains which approvals the repair needs and arranges them.
Check the license and the reviews on the pro profile, ask whether an engineer should look at the wall first, and ask to see any permit and engineer letter. Keep photos of the crack with a ruler, dated, in your records.

Before you book foundation crack injection & sealing
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Photograph with a ruler
Take clear photos of each crack with a ruler or coin for scale, inside and outside, and date them. Repeat in a few weeks.
Mark the ends of the crack
Draw a small line at each end of the crack with a pencil and write the date. If the crack grows past the mark, tell the pro right away.
Write down when it leaks
Note whether water enters during heavy rain, snowmelt or sprinkler use. The timing helps the pro choose the material and decide what else to check.
Clear the wall for access
Move furniture, shelving and stored items away from the wall, and tell the pro about drywall or paneling that covers it. Open access shortens the visit.
Check gutters and grading
Make sure downspouts discharge well away from the foundation and the soil slopes away from the house. Share what you find so the pro can include it.
Ask about the next step
Ask the pro what they will watch for after the repair and when an engineer should be called. A clear plan is worth as much as the injection itself.
