Why I started this business in Hilo
I learned masonry on big commercial jobs, where every wall got checked against the plans and nobody was allowed to guess. I started Mainstay Hilo Concrete and Masonry in Hilo in 2020 to bring that same care to people's homes. We're best known for block, brick and stone work that's laid out right and finished clean, and we take the smaller repairs a lot of bigger outfits pass on.
What I care about most is the cause. Around Hilo, water is usually behind failing masonry, and rainfall can change a lot over a short distance, so two houses not far apart can wear in different ways. New mortar won't last long if the water that ruined the old mortar is still getting in. I'd rather do your job right once than come back and patch it twice.
What you can expect when you hire us
We find the cause before we fix anything
Before we touch your wall, we work out why it's failing, because cracked block or worn joints usually point to water or movement coming from somewhere else. Fixing that first is what lets the repair hold.
A written estimate you can compare
I come out, measure and put the work, the materials and the steps in writing, so you can set it next to any other bid. It's free, with no pressure to book, and you can ask for one on our contact page.
The person who quotes it runs it
I'm the one who looks at your job, and I'm the one running it on site with our own crew. What we agree on at your house is what gets built.
Licensed, insured and clear on permits
We're licensed and insured, and we settle permit and engineering questions with you before any work starts. If your job needs a permit, we handle the paperwork with the county and keep you posted on where it stands.
