What We Do

Wall & Foundation Coring

We core block, CMU, poured walls, and footers for utility lines, conduit runs and HVAC.

Slab & Floor Coring

We core drill concrete slabs for plumbing penetrations, drainage lines, and utility rough-ins.

Concrete X-Ray

We scan with GPR before drilling to avoid hitting rebar, conduit, or post-tension cables.

We cut and core to spec so plumbers, electricians, and mechanical contractors can get right to their installs without rework or delays.

Here’s what our community says

Andrew was very responsive and flexible in his scheduling. Upon arrival, he was on time, extremely thorough, and precise. I would highly recommend Baygrade to anyone looking for a professional job.

Jon G.

I am a custom home builder and I need multiple holes drilled in an epicore poured slab. It ranged from 8 to 14 inches thick. Andrew did a great job for us, showed up as scheduled, communicated by text/pictures, had no problem working around other subs. He checked all the boxes. I highly recommend him.

Gary H.

I highly recommend Baygrade for concrete cutting! Andrew was great to work with, very professional and knowledgeable. We had 40 feet of concrete cut for our house remodel, and it’s all set for the plumbing and electrical work. Andrew communicated start and end times, cleaned up, and did a great job. Good pricing too!

Yes. Our diamond core bits cut through rebar without issue.

Yes. We drill through CMU block, poured concrete, and most masonry substrates.

It depends on the pipe or duct size. Most residential plumbing runs through 3 to 4 inch cores, while HVAC penetrations often require 6 inches or larger.

Yes. We drill horizontal and vertical penetrations in slabs, walls, foundations, and overhead.

Standard depths cover most commercial and residential work. For deep or extended cores, ask us about barrel extensions.

We drill wet in all cases. Water cools the bit and controls dust for the safety of the driller.

We use a slurry vacuum system to capture and contain wet slurry on-site, keeping the work area clean and protecting drains.

We offer GPR scanning before drilling to map what is inside the slab or wall. We recommend it on any job where hitting a hidden element would be costly or dangerous.
