Uneven concrete repair across NH, ME & MA
Concrete Leveling in New Hampshire, Maine & Massachusetts
One slab sitting higher than the next? We check whether the concrete is still sound enough to save. If it is not, we tell you what makes more sense.
Concrete leveling, in plain English
Concrete leveling fixes a slab section that has dropped. 603 checks that the concrete is worth saving and that the house foundation is not moving before we say yes.
An uneven edge can catch a toe, hold water, or make a driveway feel rough every time you cross it. Covering the edge does not fix why the section moved. We inspect the condition of the concrete and the area around it first.
This service is for concrete that may still have useful life left. If the slab is badly broken, crumbling, or part of a problem under the house, we will recommend the more honest route.
Concrete leveling sits within our structural and foundation repair services, but a walkway and a building foundation are not the same job.
Concrete surfaces we evaluate
The slab condition decides whether leveling is a fit. Common places worth checking include:
Walkways
Raised joints and low sections near steps, doors, or paths around the home.
Patios
Sections that dropped, collect water, or no longer meet the surrounding surface cleanly.
Pool decks
Uneven panels around the pool where access and slab condition still allow a repair.
Garage floors
Local settlement or mismatched sections that are separate from structural foundation movement.
Basement floors
Uneven concrete that is not acting as the building’s structural slab foundation.
Level it or replace it?
Leveling may make sense
- The slab is mostly intact
- One or more sections have settled
- The mismatch is local and measurable
- The problem is separate from building movement
Replacement may be the better call
- The concrete is crumbling across a wide area
- The slab has broken into many loose pieces
- The surface has lost too much material to serve well
- A structural foundation problem needs a different plan
We would rather turn down a leveling job than sell you a short-lived fix on concrete that is already done.
What happens before we write the quote
- We look at the change.
Where did the slab drop, and how is that affecting the way you use the space? - We check the concrete.
Cracks, broken edges, surface loss, and the number of affected sections all matter. - We look around it.
Drainage, access, nearby structures, and visible base conditions can change the repair plan. - We rule out a problem under the house.
If the building foundation is moving, concrete leveling is not the page we hide behind. - We give you the scope in writing.
You will know what we recommend and what it costs before work starts.
Three concrete jobs that should not be mixed up
| Service | Best fit | What decides it |
|---|---|---|
| Concrete leveling | An existing settled slab that may still be sound enough to save | Condition, movement, access, and cause |
| Slab foundation repair | An existing slab that supports a building | Movement under the building and the repair plan |
| New or replacement slab | New construction or concrete that is beyond a focused repair | Use, load, drainage, base, and project design |
If you are unsure which one you have, that is normal. The free inspection is meant to sort it out.
What changes the price?
Concrete-leveling price depends on slab size, the number of sections, access, concrete condition, and what caused the movement. We quote it after we see it.
A single walkway panel and several driveway sections are different jobs. So are an intact slab and concrete that is breaking apart. The inspection and estimate are free, and the written quote comes within 24 hours.
Concrete leveling questions
What is concrete leveling?
Concrete leveling fixes a slab section that has sunk below the spot where it should sit. The slab first has to be in good enough shape to keep using.
Is concrete leveling better than replacement?
It can be when the concrete is mostly intact and settlement is the main problem. Replacement is usually the better call when the slab is badly broken, crumbling, or no longer worth saving.
Can every sunken slab be leveled?
No. Concrete condition, access, the cause of movement, and nearby structures can rule it out. We inspect those points before recommending the service.
Can you level a slab foundation?
A slab that supports a building needs a structural foundation assessment. That is different from leveling a settled walkway, patio, or driveway section.
How much does concrete leveling cost?
603 does not have an approved flat price for this service. We measure the affected sections, check the concrete, and provide a written quote after a free inspection.
How long will the repair last?
That depends on the slab condition, the cause of movement, and the approved repair plan. We will put any service-specific warranty in the written proposal rather than promise a blanket term online.
See if the concrete is worth saving
We will inspect the settled sections, check the surrounding area, and tell you whether leveling makes sense. If replacement or a structural repair is the better call, we will say so.
