Expansion joints are intentionally placed between sections of concrete to allow movement caused by temperature changes, moisture, settling, and normal use. Although these joints serve an important purpose, leaving them open or allowing the existing sealant to fail can expose the space beneath the concrete to water, dirt, weeds, and debris.
Dotzler Caulking provides professional expansion joint sealing for residential and commercial concrete throughout Omaha and surrounding communities. We remove failed material when needed, clean and prepare the joint, install backer rod where appropriate, and apply a flexible professional-grade sealant.
Properly sealed expansion joints help reduce water intrusion, keep debris from collecting between concrete sections, improve the finished appearance of the surface, and support the long-term condition of the surrounding concrete.
Expansion joints are designed to accommodate movement, but they also create openings where water, dirt, sand, weeds, and debris can collect. When existing sealant cracks, separates, sinks, or disappears, the joint is left exposed.
Water entering an open joint may wash away supporting material beneath the slab, especially during heavy rain or repeated freeze-thaw cycles. Debris inside the joint can also limit proper movement and contribute to pressure along the concrete edges.
Professional expansion joint sealing creates a flexible barrier between adjoining concrete sections. The sealant helps keep water and debris out of the joint while allowing normal expansion, contraction, and movement.
Proper joint preparation, backer rod placement, sealant depth, and material selection all affect the durability of the finished seal. A correctly installed joint can improve appearance, simplify maintenance, and help protect the surrounding concrete.
We use a careful process to inspect, clean, prepare, and seal concrete expansion joints with materials selected for the joint dimensions and expected movement.
Contact us by phone or through our website and tell us about the driveway, sidewalk, patio, or commercial concrete joints that need attention.
We evaluate the joint width and depth, existing sealant, surrounding concrete, accessibility, and visible signs of water, debris, erosion, or deterioration.
Failed sealant, loose material, weeds, dirt, and debris are removed as needed so the joint can be properly prepared for new sealant.
We install backer rod where appropriate, apply a compatible professional-grade joint sealant, and tool or level the material for a clean, consistent finish.
We inspect the completed joints, clean the immediate work area, and provide relevant guidance regarding curing time and future maintenance.
Every expansion joint sealing project is evaluated individually. Our estimate identifies the joints being serviced, the condition of the existing material, the preparation required, and the recommended sealant for the application.
We stand behind our expansion joint sealing work with a workmanship warranty for added peace of mind. Warranty coverage may vary based on the joint condition, concrete movement, surrounding surfaces, drainage, weather exposure, and materials used. Applicable warranty details will be reviewed as part of your estimate.
Open expansion joints can collect water, dirt, weeds, and debris that affect the appearance and performance of your concrete. Sealing these joints creates a flexible barrier while still allowing adjoining slabs to move naturally.
Dotzler Caulking can inspect your concrete joints, remove failed material, and recommend an appropriate sealing solution for your driveway, sidewalk, patio, pool deck, or commercial property. We provide expansion joint sealing throughout Omaha, Bellevue, Papillion, Gretna, Elkhorn, Bennington, and nearby communities.

An expansion joint is a planned space between adjoining sections of concrete or between concrete and another structure. The joint gives the slabs room to expand, contract, and move in response to temperature changes, moisture, settling, and normal use.
Expansion joints should remain flexible rather than being filled with a rigid material. A properly installed joint sealant helps keep water and debris out while allowing the necessary movement.
Sealing expansion joints helps prevent water, dirt, weeds, insects, and debris from entering the open space between concrete sections. This can reduce erosion beneath the slab, protect the joint edges, improve appearance, and allow the joint to move more freely.
Leaving joints open can allow standing water and unwanted material to collect, particularly in driveways, patios, sidewalks, and other exposed concrete surfaces.
Expansion joint sealant may need replacement when it becomes cracked, brittle, loose, sunken, separated from the joint walls, or completely missing. Other signs include standing water, weeds growing through the joint, debris collecting in the opening, or visible deterioration along the concrete edges.
An inspection can determine whether a localized repair is appropriate or whether the affected joint should be fully cleaned and resealed.
Failed sealant, loose filler, weeds, dirt, and debris are removed as needed before the joint is resealed. The joint walls must be clean and stable so the new sealant can bond properly. Depending on the joint depth, backer rod may also be installed to control the amount and shape of the sealant and allow it to move correctly.
Concrete expansion joints commonly use flexible polyurethane or other professional-grade joint sealants designed to withstand movement, moisture, and outdoor exposure. Self-leveling products may be used for suitable horizontal surfaces, while non-sag sealants may be needed for sloped or vertical applications. The appropriate material depends on the joint width, depth, orientation, surrounding concrete, expected movement, and exposure conditions.
The cost of expansion joint sealing depends on the total linear footage, joint width and depth, condition of the existing filler or sealant, amount of cleaning and removal required, accessibility, and type of material used. Dotzler Caulking provides project-specific estimates so you understand the recommended preparation, sealing process, and price before work begins.
