Concrete Caulking & Joint Repair with NexusPro®

Seal the joints, cracks and gaps in your concrete with NexusPro® to stop water intrusion, cut down on freeze-thaw damage and help prevent future settlement.

What Is Concrete Caulking?

Concrete caulking fills and seals joints, cracks and gaps with a flexible material that moves as the slab expands and contracts. Closing these openings helps keep water and deicing salts from reaching and eroding the supporting soil below.

Caulking is preventative maintenance, not simply a cosmetic upgrade. When your concrete is still level, joint sealing may be all that’s necessary. If the slabs have already settled or become uneven, they should be lifted first and sealed afterward for longer-lasting protection.

Why NexusPro® Outlasts Hardware-Store Caulk

NexusPro® is a self-leveling polyurethane sealant engineered to stay flexible through seasonal expansion and contraction. It also stands up to UV exposure, water and deicing salts, making it better equipped for what concrete deals with in the Texas Panhandle and Northwest Texas.

Unlike general-purpose tube caulk, NexusPro® is professionally installed by Legacy Supportworks-trained crews who clear away failed material, prepare the joint and lay down the correct amount of sealant for a clean, lasting result.

    • Covered by an industry-leading transferable warranty
How It Works

Our NexusPro® Concrete Caulking Process

Step 1

Free Concrete Inspection

A Design Specialist walks your concrete to identify open joints, cracks and gaps that should be sealed. You’ll receive a free written estimate outlining the recommended repairs and project scope.

Step 2

Clean & Prepare the Joints

Our crew clears away old or failed caulk and thoroughly cleans every joint. A clean surface allows NexusPro® to bond securely for long-lasting performance.

Step 3

Set Backer Rod (When Needed)

On wider joints, we install a closed-cell backer rod ahead of the sealant. This helps control the sealant depth, improves flexibility and creates a stronger, longer-lasting seal.

Step 4

Apply NexusPro®

Our proprietary, self-leveling polyurethane sealant is carefully applied to fill each joint, crack or gap. The material settles evenly into a smooth, waterproof barrier that moves with your concrete.

Step 5

Finish & Curing

We tool the sealant for a clean, finished appearance, remove excess material and allow it to cure. Most joints can return to normal use within a few hours, depending on site and weather conditions.

Where Concrete Caulking Belongs Around Your Property

Why Seal Concrete Joints Now?

Open joints allow water and deicing salts to reach the soil beneath your concrete. If the slabs are still level, sealing now can help reduce erosion and future settlement. If PolyLevel® lifting is needed, NexusPro® seals the restored joints afterward to help protect the repair.

Common Applications

  • Driveway expansion joints
  • Sidewalk joints and cracks
  • Patio joints
  • Pool deck edge joints
  • Garage floor joints and cracks
  • Front steps and stoop joints

Don't just take our word for it

See what our customers have to say about our work.

Legacy SupportWorks was referred to me by Bernie Sanders with Sir Speedy. When doors began to not close properly and there were noticeable gaps between the floor and molding, we knew it was time to get some foundation work done on our home. We shopped around and were pleased with the value and responsiveness of Legacy Support Works. I felt comfortable with them in my home, they delivered what they promised when they promised and left my home clean. From Tessa who made the initial contact, to the gentleman putting my carpet back in place, customer service was outstanding.

When Karen H. saw some cracks on her wall, she knew something was wrong. She first called a local contractor and they told her that the cracks were being caused by the trees in her backyard. Karen wasn’t convinced by their explanation so she decided to get a second opinion and called Legacy Supportworks. In this video she talks about the experience she had with the company and why she was confident to hire them as the right company for the job. “What we got from Legacy Supportworks was not just a company that will be there for us through the whole process, but be there for us through any other problems that we have in the future”, says Karen.

Before & after photos

Check out before and after photos from some of our completed projects.

  • Stabilizing a Crawlspace in Pampa, TX

    This home had crawlspace beams that were cracking and lacked stabilization. 

    Years of shimming had only been a “band-aid” fix and this customer was looking for a permanent solution.

    Our crew installed steel beams and steel smartjacks on engineered fill.

    The result was a permanently stabilized floor!

  • Concrete Repair in Spearman, TX

    A customer reached out after seeing a video of concrete lifting using injection methods and wondered if it could work for their front porch. Their home, built in 1968, features a large concrete porch with a section that originally had a planter between it and the house. At some point, the planter was covered with concrete, which has since sunk about 4 inches. Both sections measure approximately 8×12. While the porch itself was fine, they wanted a solution to lift the concrete over the old planter rather than starting from scratch. Legacy inspected the situation and provided a tailored solution to restore their home.

  • Foundation Repair in Guymon, Oklahoma

    Just four years after adding a first porch for relaxation, a homeowner in Guymon, OK found himself facing a disheartening problem – his beloved porch had settled a shocking 2 feet into the ground, taking his dreams of peaceful rocking chair afternoons with it. As depicted in our before photo, this alarming sinkage rendered the space unusable. To lift and stabilize the sinking structure, we deployed our trusted Push Pier system, meticulously engineered to provide strength and elevation from deep below the surface. The transformation is apparent in the after photo, where the porch now stands level and secure, promising many future years of comfort and stability. At Legacy Supportworks, reviving your home’s foundation to ensure lifelong enjoyment and safety is not just our mission—it’s our commitment to you.

Frequently Asked Questions

How do I know when concrete joints need recaulking? 2026-10-05T15:49:03-05:00

Concrete joints should be inspected when the existing material has cracked, pulled away from the slab, fallen out or left visible gaps. Open joints should be handled before wet or freezing weather drives more moisture beneath the concrete. A professional inspection will tell you whether the joint needs cleaning, backer rod and new sealant. 

Will concrete caulking stop a slab from sinking? 2026-10-05T15:48:03-05:00

Concrete caulking will not lift or stabilize a slab that has already settled. It helps protect level or recently lifted concrete by reducing the amount of water and deicing salt entering the joints and soil below. When slabs are already uneven, they should be inspected for concrete leveling before joint sealing. 

Can I caulk concrete myself using tube caulk? 2026-10-05T15:47:33-05:00

You can use hardware-store tube caulk, but general-purpose products may shrink, harden, crack or pull away as concrete moves through seasonal temperature changes. NexusPro® is a professional-grade, self-leveling polyurethane sealant applied over properly prepared joints. For homeowners after a cleaner finish and longer-lasting protection, professional concrete caulking is generally the better investment. 

Concrete caulking vs. concrete sealing: what’s the difference? 2026-10-05T15:47:09-05:00

Concrete caulking and surface sealing each protect a different part of the slab. NexusPro® fills joints, cracks and expansion gaps with a flexible, waterproof bead that flexes with the concrete. Concrete sealant soaks into the concrete surface to help protect it from moisture, stains and wear. Used together, they cover both the openings and the surrounding surface. 

Do I need concrete caulking after PolyLevel® lifting? 2026-10-05T15:46:38-05:00

In most cases, yes. PolyLevel® brings the slab back into position, while NexusPro® helps protect the repair by sealing joints and cracks afterward. This keeps water and deicing salts from easily reaching the soil below, the same conditions that can contribute to settlement. Open joints leave the supporting soil more exposed to future moisture and erosion. 

How long will NexusPro® caulking last? 2026-10-05T15:46:12-05:00

NexusPro® is built as a long-term concrete joint seal. Its flexible, self-leveling polyurethane formula holds up against UV exposure, water, deicing salts and repeated freeze-thaw cycles without going brittle. It is professionally installed and backed by an industry-leading transferable warranty, providing more durable protection than many general-purpose hardware-store caulks. 

How much does concrete caulking cost? 2026-10-05T15:45:39-05:00

Concrete caulking is typically priced by the linear foot of joint or crack sealed. Project cost depends on total footage, joint width, existing caulk removal and prep needs. Since joint sealing is preventative maintenance, it tends to cost far less than repairing settled or damaged slabs later. Request a free written estimate for exact project pricing.
