What we do

Demolition & Concrete Removal

Old concrete out, debris hauled away, and the ground graded back to a surface you can build on. Most of our tear-outs are the first stage of a job we are also pouring, so the site is left ready for what comes next rather than simply cleared.

Most replacement jobs start with tear-out, and separating the tear-out from the pour is how they go wrong. We break out and remove driveways, patios, walkways, steps and slabs, take down failing structures that are in the way, break out old foundations from under a standing house, haul the debris off, and grade the ground back to a surface somebody can actually build on. Having the same crew and the same machines come back to pour has one real advantage, and it is not the price: nobody hands off. When the old slab comes up, the reason it failed is usually sitting right there underneath it — a base that was never thick enough, or ground that has been holding water for twenty years. The people looking at that are the same people who have to answer for what goes back on top. Under a separate demolition contract, that same discovery becomes a change order and a week of waiting. A job in Dundee shows how it plays out: a failing, rotten deck came off the front of a house, and a new concrete front porch, sidewalk and steps went in where it had been. Demolition and removal was the first line on the estimate, and the same crew finished the job.

What is included

  • Driveways, patios, walkways, steps and slabs broken out and hauled away
  • Old foundations broken out from under a standing house, on cribbing
  • Graded back to a buildable surface — and usually by the crew that is coming back to pour
An excavator arm reaching under a house held up on temporary timber cribbing, breaking out the old foundation below it, with a cut slab of the original concrete lying in the dug-out trench

Our process

How demolition jobs run

  1. Look at what is under it

    We come and look before quoting, because what matters is not the slab, it is what is beneath it and what has to survive the removal — utilities, a foundation, a tree, a neighbor's fence.

  2. Protect access and the ground you are keeping

    Where the machine goes, where the truck sits and what gets matted or protected are decided first. Most of the damage on a demolition job happens to the things nobody planned around.

  3. Break out and haul off

    The concrete comes up, gets loaded and leaves. Disposal is inside the number we give you rather than added to it afterwards.

  4. Grade back to something buildable

    The hole gets brought back to a compacted, level surface. If we are pouring, this is the start of the base. If we are not, you get a site the next contractor can work on.

Questions

Questions about demolition work

  • Yes. It is inside the number we give you rather than a line that appears later. Concrete disposal is a real cost and pretending otherwise just moves the argument to the end of the job, which is the worst possible time to have it.
