About our Castro Valley masonry contractor company

Our story started with old brick and garden walls
I taught myself masonry by patching old brick and building small garden walls, then learned the rest on the crews of masons who'd been at it a lot longer than me. I started this business in Castro Valley in 2013, and I still answer the phone and come out to look at most jobs myself. Most people call when something's cracked, crumbling or loose, and the first thing I want to know is why it failed, because a patch that ignores the cause just comes back.
We do a lot of repair on older brick, mortar and chimneys, plus the new walls, pavers and stone that go with a house, and you'll find the full list on our home page. Castro Valley isn't its own city, so the county handles permits here, and when your job needs one we check with the county and take care of the paperwork and inspections. I like people to understand their house a little better when I leave, so ask me anything, or send us a note to get started.

Our values, as you'll see them on your job
Here's what you can expect from us, from the first look at a cracked wall or a loose chimney to the day the crew packs up and leaves.
The owner, start to finish
I come out to look at the job myself, and my crew does the work with me checking in along the way. That means the person who looked at your wall is the one keeping an eye on it.
The cause before the fix
Before we touch brick, stone or mortar, we work out why it failed, which usually comes down to water, movement or an earlier repair done with the wrong mortar. That way you're paying to fix the problem and not just the crack you can see.
Honest about smaller repairs
If a few bricks and some fresh mortar will do it, that's what I'll tell you, even when a bigger job would mean more work for us. I'd rather you trust us enough to call again.
A written estimate in plain words
I look at the work with you on site and then follow up with a written estimate, free and with no obligation. It spells out what we plan to do and what goes into it, like how much is damaged, how easy it is to reach and the materials, so nothing starts until you know.
