Crack widening, surface flaking or one slab edge dropping? Call us any time. Our local concrete professionals inspect the concrete and base, then explain whether sealing, patching, resurfacing, leveling or replacement fits the actual damage before work starts.
What it covers
Our Concrete Repair and Resurfacing Services in Cottage Grove
- Crack assessment. Your technician checks width, movement and whether both sides remain level. A stable surface crack differs from a dropped panel.
- Joint and crack sealing. Stable joints can be cleaned and sealed to limit water and grit entry before winter. Sealing does not stop movement below the slab.
- Small-area patching. A broken edge or local spall may accept a patch after loose material is removed and sound concrete is exposed.
- Surface restoration. A bonded resurfacing layer may cover light or moderate scaling if the underlying slab is sound; color will not match perfectly.
- Repair alternatives. An intact sunken panel may fit leveling; widespread breakup or active base loss can justify replacement.
Signs
Signs You Need Concrete Repair and Resurfacing
- A crack opens wider from one season to the next

- Water collects along an open joint before freezing
How it goes
How Our Concrete Repair Work Proceeds
- Show the damage. Give the Cottage Grove address, slab age and photos from above and close up. Note when the crack or scaling appeared.
- Inspect movement. Your technician checks whether the base, grade and slab body are stable enough for a focused concrete repair.
- Agree on method. Sealing, patching, resurfacing, lifting or replacement is listed with surface preparation and price before work starts.
- Protect the finish. After approved work, ask for curing, temperature and first-winter care instructions tied to the repair material.
Cost
What Affects the Cost of Concrete Repair and Resurfacing in Cottage Grove
A stable crack and a scaled slab need different preparation, so the quote turns on:
- Damage depth. A hairline crack and a broken-through panel call for different material and labor.
- Surface preparation. Loose scaling and failed patches must be removed before a bonded layer is placed.
- Movement below. Base washout or settlement can turn a surface job into lifting or replacement.
- Weather window. Dryness, temperature and curing protection affect scheduling and the repair method.
For concrete repair and resurfacing, one of our local concrete partners will walk you through the scope and the price before any work starts. The concrete cost factors note compares preparation and replacement without pricing this damaged slab.

Before you call
Before You Call About Concrete Repair
Mark the crack ends and compare photographs over time; a growing offset is more important than a single hairline width. NRMCA CIP 6 explains shrinkage cracking and joint layout. CIP 2 describes freeze-thaw scaling and why a heavily deteriorated surface may not be a good resurfacing base. Keep deicers off new or recently repaired concrete as instructed, and ask when a patch can be exposed to traffic. Photograph any previous sealer or coating so your technician can plan bonding preparation.

FAQ
Concrete Repair & Resurfacing FAQs
Is a hairline crack in new concrete a defect?
Not by itself. Concrete shrinks as it dries, and fine cracks, especially between joints, are common; irregular cracks are unsightly but generally do not affect the slab's integrity. Raise it with your technician if the crack widens over time, one side rises above the other, or the slab was poured without joints at reasonable spacing.
Should I seal cracks before winter?
Yes, if the crack is stable. A flexible crack or joint sealant keeps meltwater and grit out, which slows the damage freeze-thaw can do. It will not stop a crack that is still moving. Clean and dry the crack first, follow the product's temperature limits, and ask your technician about any crack that is widening or has one side higher.
Does concrete repair come with a warranty?
Ask, because terms vary by job and method, and a repair over a moving base is hard to guarantee. Get in writing what is covered (bond failure, a crack coming back, color), for how long, and what you have to do to keep it valid, such as avoiding certain deicers or resealing on schedule.
Can a concrete driveway crack be repaired without replacing the slab?
Yes, when the panel remains sound and the crack is stable, sealing or a focused patch may fit. A dropped edge, repeated widening or broken base needs a different plan. Ask your technician to compare the damaged area with driveway replacement and explain what each option leaves untouched.
Will resurfacing hide every old crack?
No. A thin bonded layer follows the condition of the concrete beneath it and will not stop movement. Loose material has to come off first, and the new finish may differ in color from adjoining slabs. Ask which cracks will be repaired before resurfacing and what preparation is included.
Call with Cottage Grove concrete photos and the age of the slab so a repair can be compared with lifting or replacement.
