Why homeowners pick Tri-County

Built for Delaware weather, finished to last

Permits Checked

Slab removal is one thing; structures are another. We check permit requirements and asbestos risk on pre-1980 structures before demolition starts.

Debris Hauled Away

Hauling and disposal are included in the estimate. Concrete and rebar are taken to licensed C&D recycling facilities when possible.

Ready for the Next Phase

The job is not finished until the site is clean. We leave it broom-swept for repour or final-graded for what comes next.

Details

When the old concrete has failed, resurfacing is usually just a delay.

Demolition is often the first real step toward a concrete project that lasts. If an old driveway, patio, slab, sidewalk, shed, garage, or retaining wall is already cracked, settled, or failing, covering it up rarely solves the problem. Tri-County Construction handles selective and full demolition across Delaware, including hauling and disposal, so the site is ready for repour or rebuild.

Most demolition work pairs directly with new concrete. The old slab comes out, the base is corrected, and the new pour starts from stable ground instead of a compromised surface. We also perform standalone demolition for site clearing, failing detached structures, old wall removal, and prep before another contractor takes over.

Structures can bring permit requirements, and pre-1980 structures need asbestos awareness before demolition. Concrete can sometimes be crushed on-site for fill when appropriate, reducing hauling costs. When disposal is needed, material goes to a licensed C&D facility and recyclable concrete and rebar are handled responsibly.

FAQ

Common questions

Don't see your question? Call (302) 419-3232 or send a quick note through the contact form — we usually reply same-day.

Do you haul away the debris?
Yes, hauling is included in the estimate. We dispose at licensed C&D recycling facilities, and concrete and rebar are recycled when possible.
How much does demolition and repour cost vs. resurfacing?
Demo and repour costs 30–50% more upfront but can last 30+ years. Resurfacing is cheaper but rarely lasts past 5–8 years on a failed slab.
Do you need permits for demolition?
It depends on the scope. Slab and walkway demo usually does not need one. Outbuildings and structures often do, and we pull them.
What affects the cost of demolition in Delaware?
Demolition pricing is driven by total square footage and debris volume, thickness of concrete being removed, structural vs. slab-only demo, disposal and recycling fees, dumpster or roll-off costs, and site access for the excavator. Every project gets a free on-site estimate — call (302) 419-3232.
