Cracks, Joints &
Surface Sealing.
From individual cracks and failing control joints to full-slab penetrating surface protection — our sealant systems are engineered for Colorado's extreme freeze-thaw cycles. Stop water intrusion, prevent further damage, and protect the entire slab.

How It Works
Caulking & Joint Sealing
Process
Professional caulking is more than just filling — it's about creating a lasting, flexible seal that moves with Colorado's freeze-thaw cycles for years.
Inspection & Assessment
We examine all cracks and joints to determine type (structural vs. cosmetic), cause, and the best repair method. You get a detailed quote with no surprises.
Clean & Prepare
Cracks and joints are thoroughly cleaned of debris, dirt, and loose material using wire brushes and compressed air. Clean surfaces ensure proper sealant adhesion.
Install Backer Rod
For larger cracks and control joints, we install foam backer rod to control sealant depth and ensure proper expansion/contraction performance.
Apply Joint Sealant
A professional-grade flexible joint sealant is applied to fill each crack and joint completely. Designed for Colorado's extreme temperature swings.
Tool & Finish
The sealant is tooled smooth for a clean appearance and proper adhesion to both sides of the crack or joint.
Cure & Protect
Sealant cures to full flexibility within 24–48 hours. The repaired area is now protected from water, ice, and further damage.
Why Professional Caulking & Sealing Matters
Full-Slab Protection
Penetrating
Surface Sealant
Beyond crack repair, a penetrating surface sealant protects the entire slab — repelling water, oils, and freeze-thaw damage from within the concrete itself.
Penetrating Surface Sealant
A penetrating surface sealant that soaks into the concrete matrix, repelling water and chlorides from within. Ideal for driveways, walkways, and patios that need protection without changing the appearance of the concrete. Clear, low-sheen finish that won't peel, flake, or fade.

Crack Repair & Joint Sealing
Cracks & Joints —
We Fix Both
Unplanned cracks and intentional control joints use the same technique — professional flexible sealant. We handle both in a single visit.
Driveway Cracks
Colorado's freeze-thaw cycles are brutal on driveways. We seal cracks before water intrusion causes larger problems.
- Hairline cracks
- Settlement cracks
- Expansion joint repair
- Edge cracking
Sidewalk Cracks
Cracked sidewalks are trip hazards and liability risks. Our flexible sealants restore safety and appearance.
- Control joint cracks
- Corner breaks
- Tree root damage
- Settlement cracks
Patio Cracks
Don't let cracks ruin your outdoor living space. We repair and seal patio cracks to prevent water damage.
- Paver joint repair
- Slab cracks
- Expansion joints
- Decorative concrete
Control Joint Sealing
Control joints are intentional cuts designed to guide cracking — but they still need sealing. We rout out failed material and pack them with proper flexible sealant to block water intrusion.
- Saw-cut joints
- Tooled joints
- Failed joint re-sealing
- Driveway joints
Expansion Joint Repair
Expansion joints allow concrete to move with temperature changes. Worn or missing material lets water in. We replace it with professional-grade flexible backer rod and sealant.
- Garage-to-driveway
- House-to-slab
- Sidewalk sections
- Commercial joints
Commercial Concrete
Warehouses, parking lots, and commercial properties need crack repair to maintain safety and professional appearance.
- Warehouse floors
- Parking lots
- Loading areas
- Retail entrances

Flexible Sealant vs. The Alternatives
Not all crack repair methods are equal. See why professional flexible sealants outperform rigid fillers and DIY kits.

Flexible Sealant
Professional-grade solution that expands and contracts with temperature changes. Best for Colorado's climate.
Rigid Filler
Doesn't flex with temperature changes. Will re-crack within 1-3 years in Colorado's freeze-thaw cycles.
DIY Kit
Consumer-grade products lack the flexibility and durability for professional results. Often need annual reapplication.
FAQ
Common Questions About
Caulking & Surface Sealing
Most crack and joint caulking jobs range from $150–$800 depending on the length, width, and number of cracks or joints. Penetrating surface sealant pricing depends on the square footage of the slab. We provide free on-site quotes so you know the exact cost upfront.
Most DIY and rigid fillers can't handle Colorado's extreme temperature swings. As concrete expands and contracts, rigid materials break their bond and crack again. Our flexible sealants move with the concrete.
Most residential crack repair jobs are completed in 1-3 hours. The sealant needs 24-48 hours to fully cure, but you can walk on it within a few hours.
No — crack repair seals cracks but doesn't lift or level concrete. If your concrete is uneven, you need our concrete lifting service. We often combine both services on the same visit.
Yes — and we treat them as the same service. Both unplanned cracks and intentional control or expansion joints are sealed using the same professional-grade flexible sealant. We commonly handle both in a single visit, so you get everything done at once.
Yes, we can repair cracks in stamped, stained, and decorative concrete. We take extra care to minimize visual impact during the repair.
Hairline cracks (less than 1/8 inch) are often cosmetic and may not need immediate repair. However, sealing them prevents water intrusion that can cause larger problems over time. We'll give you an honest assessment.
Common causes include: soil settlement, freeze-thaw cycles, tree roots, improper installation, heavy loads, and age. Colorado's clay soils and extreme temperature swings make cracking especially common here.
Crack and joint caulking addresses individual cracks and joints with a flexible sealant. A penetrating surface sealant is a full-slab protection product that soaks into the concrete matrix to repel water and chlorides from within — it doesn't change the appearance of the concrete. The two are often used together: we seal the cracks first, then treat the full slab for complete protection.
Yes — a penetrating surface sealant can be applied to existing concrete in good structural condition. We recommend repairing any cracks or joints first so the sealant protects a fully sealed surface. We'll assess your slab on-site and tell you whether it's a good candidate.
