About Cornerstone Concrete of WNY
A family-owned concrete crew based in East Aurora, New York — 7 years of experience pouring driveways, patios, pool decks, walkways, fire pits, and building pads across the Buffalo Southtowns and Erie County.
Meet the Owner: Jim “Clapper” Clapp
Jim owns Cornerstone Concrete of WNY, and if you have spent any time around him you probably call him Clapper — almost everyone does. He is a Western New York native with kids in the area, so the work this company does is not happening in some market he flies into. It is happening where he lives.
Before concrete, Jim spent decades in business in this region, and that shows up in the parts of a contracting job that usually go wrong: returning the call, showing up when he said he would, putting the price in writing, and telling you plainly when something is going to cost more or take longer. He brings 7 years of concrete experience to the trade itself.
What he asks of the business is simple and he does not bend on it: high-quality customer service, responsiveness, and first-class concrete work. If you call, you get Jim — not a call centre, not a salesman working on commission, and not a crew you have never met turning up on pour day.
A Small Crew, Ten Miles From Buffalo
Cornerstone Concrete of WNY is a family-owned concrete company working out of East Aurora, New York, owned and run by Jim Clapp. It is a deliberately small operation — the person who quotes your job is the person standing on it when it is poured.
We built the business around the ten miles south and east of Buffalo on purpose. Working a tight radius means we know the ground: the clay under East Aurora and Elma, the frost line, the drainage problems that surface in a Southtowns backyard after a wet spring, and which town wants what for a sidewalk replacement. It also means we are ten minutes away when you call about something two years after the job, which is the part most contractors are not.
Seven Years of Pouring in This Climate
We bring 7 years of concrete experience, all of it in Western New York. That matters more than it sounds. Concrete poured for a mild climate does not survive here — it gets frozen and thawed dozens of times a winter, buried under snow for months, and salted from November to April. Everything we do is built around that reality: air-entrained mix, correct thickness over a properly compacted base, wire or rebar reinforcement suited to the load, control joints cut at the right spacing, and proper curing before the slab ever sees a hard freeze.
What We Pour
- Concrete pool decks — slip-resistant, poured to the shape of your pool.
- Stamped and stained concrete patios — stone, slate, brick and plank patterns, coloured and sealed.
- Concrete fire pits — pads, seat walls, columns, lighting and paver surrounds.
- Concrete driveways — new pours, replacements, extensions and parking pads.
- Sidewalks and walkways — front walks, curved paths, steps and village-spec sidewalk.
- Pads for buildings and pole barns — barn floors, metal building slabs, garage and equipment pads.
How We Work
You call or send the form. We come out — free, no obligation — and actually look at the site: grade, drainage, access for a truck, what is already there and why it failed if something did. Then you get a written, itemised price. Not a range scribbled on the back of a card, and not a number that grows once the excavator is running.
If you hire us, we tell you when we are coming and we show up. We protect what we are working around, we keep the site tidy, and when it is done we walk it with you and leave written curing and first-winter care instructions. The advice in those instructions — no de-icing salt the first season, sand for traction, keep the plow blade off the surface — is the difference between concrete that looks good for twenty years and concrete that scales in three.
Licensed, Insured, and Local
We are a licensed and insured concrete contractor and we will hand you the certificates before we start if you ask. You should ask that of anyone who works on your property. Beyond the paperwork, though, the real accountability is that our work sits on streets we drive every day, in front of neighbours we see at the store. That is a stronger guarantee than anything printed on a contract.

We bring 7 years of concrete experience to every project — driveways, patios, pool decks, walkways, fire pits, and building pads across the Buffalo Southtowns and Erie County. That is hands-on time in this specific climate, on this specific clay, which matters more than years on a sign.
