Concrete is tough—but it’s not invincible. Over time, even the best-poured surfaces can crack, shift, or wear down. If you’re starting to notice changes in your driveway, patio, walkway, or foundation, it might be time to take action.
In this guide, we’ll cover the top signs it’s time to call a professional for concrete repair in Denver, what causes common damage, and what you can do to protect your property. Whether you’re dealing with small surface cracks or sinking slabs, you’ll know what to watch for—and how All American Flatwork can help.
Why Prompt Concrete Repair Matters
Cracks may not seem like a big deal at first. But over time, small issues often lead to bigger—and more expensive—problems. Delaying repairs can create safety hazards, reduce your property value, and allow water to seep into your foundation or sub-base.
The good news? Many issues can be fixed quickly and affordably when caught early.
Let’s look at the warning signs.
1. Cracks Wider Than a Quarter Inch
Hairline cracks are common and usually not serious. But if the cracks in your concrete are wider than a quarter inch—or if they’re growing over time—it’s time to act.
These cracks often show up in:
- Concrete driveways
- Sidewalks
- Garage floors
- Foundations
Wider cracks may signal shifting soil, poor drainage, or freeze-thaw damage—especially in Colorado’s unpredictable weather.
What to do: Don’t try to fill these cracks with store-bought sealant. Professional concrete repair companies use industrial-grade materials that bond deep into the surface and prevent future spread.
2. Uneven or Sunken Slabs
If parts of your concrete look like they’re sinking or sloping, your slab may be settling unevenly. This usually happens when the ground underneath wasn’t compacted properly or has eroded over time.
You might notice this around:
- Your driveway entrance
- Front walkway
- Backyard patio
- Garage threshold
Besides being an eyesore, uneven concrete creates a major tripping hazard—and can be a red flag for deeper foundation problems.
What to do: Schedule an inspection to determine if your slab can be leveled or needs full replacement. We often recommend grinding or resurfacing to correct the slope and restore a level surface.
3. Pitting or Flaking on the Surface
Do you see small holes, pits, or flaking on the top of your concrete? That’s surface spalling. It often happens when:
- Salt is used during winter
- Low-quality concrete mix was used
- Water was added improperly during the pour
These imperfections don’t just affect appearance—they can lead to faster deterioration if ignored.
What to do: For cosmetic damage, we offer concrete resurfacing, which restores the top layer without tearing out the slab. If damage goes deeper, we may recommend more extensive repair.
4. Pooling Water or Drainage Issues
Standing water is a silent threat to your concrete. If water collects on the surface or drains toward your foundation, it can lead to:
- Erosion under the slab
- Cracks and sinking
- Freeze-thaw damage in winter
This problem is common around patios, driveways, and walkways with poor slope or drainage.
What to do: Don’t just mop up the puddles. Get a professional to evaluate the grading and recommend a fix. We often use grinding, sloping, or full re-pour depending on severity.
5. Rust Stains or Exposed Rebar
If you see reddish-brown stains or actual rebar showing through the surface, it’s a sign the steel inside your concrete has started to corrode. This typically means water has penetrated the slab and reached the reinforcement.
Left unchecked, it can lead to serious structural problems.
What to do: Call a Denver concrete repair expert like All American Flatwork immediately. Rusting rebar needs to be sealed, patched, or replaced before the damage spreads.
6. Chipping at Edges and Joints
The edges of your driveway or patio take the most abuse—from cars, lawn tools, and everyday wear. If those edges are starting to crumble or break off, it’s a sign your concrete may be nearing the end of its lifespan—or was improperly poured to begin with.
This kind of damage usually worsens quickly.
What to do: In many cases, we can grind and resurface the affected area without replacing the entire slab. If the damage is widespread, replacement may be more cost-effective.
7. Your Concrete Just Looks… Bad
Sometimes it’s not about cracks or safety—it’s about curb appeal. If your concrete is stained, discolored, or has a patchy finish, it might be time for an upgrade.
This is especially true if you’re selling your home or just want to boost its value.
What to do: Don’t live with dull, stained concrete. Ask us about decorative resurfacing, color staining, and new finishing options that give your space a fresh, modern look.
What Causes Concrete Damage in Denver?
Denver’s climate is a big factor in concrete wear and tear. Between freeze-thaw cycles, shifting clay soils, and high UV exposure, even the best surfaces can show signs of age.
Other common culprits include:
- Improper installation
- Poor drainage
- Heavy vehicles
- Tree roots
- Road salt and de-icers
That’s why it’s so important to work with a concrete company like All American Flatwork which understands how to build for Colorado’s climate.
