ABOUT CHIMTECH

About ChimTech — Brian Dobuis, Founder, and the Chicago Crew

Brian Dobuis founded ChimTech with a 10-person crew and no subcontracting. Every job is performed by the same team — no day-labor fill-ins, no regional routing.
Four service technicians in branded work uniforms stand in front of ChimTech service vehicles parked on a residential street lined with classic homes. The team members wear dark jackets and tan work pants, displaying professional branding including flame logos on their apparel. The white service van and truck behind them indicate this is a chimney and fireplace maintenance company ready to serve homeowners in the neighborhood.
WHO WE ARE

A Crew That Stays Accountable

ChimTech is a Chicago chimney company — ten people, one crew, every service performed by the same team.
“I’m Brian Dobuis, the founder. ChimTech handles chimney cleaning, inspection, repair, waterproofing, relining, installation, and restoration across Chicago and the surrounding suburbs. When you call, you reach the same crew that shows up at your door — there’s no call center forwarding your job to whoever is closest that week. We come to the property; there’s no shop for you to visit. That’s the whole model.”

THE REASON

Why I Started ChimTech

I started ChimTech because homeowners needed a chimney company that stayed reachable after the first visit.

Here’s what I kept seeing. A homeowner books a cleaning, the crew does the job and leaves, and then a follow-up question comes up — something from the inspection report, a new symptom, a permit question. They call back and get a different person. Or no one. Or a voicemail that sits for three days. That pattern doesn’t work for a fire system, and it doesn’t work for a service that touches the structural masonry of an older home.
I built ChimTech around the opposite idea. Chicago has a long heating season, hard winter moisture cycling, and a housing stock full of pre-1960 chimneys built with materials and methods that require era-matched repairs. ChimTech exists to handle all of that — and to stay accountable when it does.

HANDS ON, NEIGHBORHOOD BY NEIGHBORHOOD

A Founder Who Has Worked These Chimneys Directly

Ten people work every ChimTech job — the same ten people, on every visit.
No subcontracting, and no day-labor fill-ins when the schedule gets heavy. If we’re booked, we tell you when we can get there — we don’t fill the gap with people I haven’t trained and can’t reach after they leave. Crew accountability means the homeowner knows who did the work and can reach those people for follow-up. That’s an operational decision, not a marketing statement.
I’ve worked chimneys across Chicagoland personally — the clay-lined stacks in Beverly bungalows off Longwood Drive, the brick two-flats along Milwaukee Avenue in Avondale, the older multi-flue systems in the Hyde Park greystones. The failure patterns in a 1922 bungalow in Portage Park (60641) aren’t the same as a 1950s brick Georgian in Norwood Park (60631), and that familiarity shapes how every job gets scoped before a tool comes out of the truck.
Every visit produces a written record — what the crew found, what was done, and what needs attention next time — delivered at job close, not days later. It becomes a permanent reference tied to the property, useful for insurance documentation, ownership transfers, and giving any future inspector a real baseline rather than guesswork.
STRAIGHT ON CREDENTIALS

What ChimTech Does and Does Not Claim

ChimTech works to the building code of whichever municipality the property sits in, and follows NFPA 211 standards on every inspection.
I’ll be direct: ChimTech does not currently hold independent chimney-specific certifications — CSIA, NFI, or others — and I’m not going to list credentials that don’t exist. What ChimTech has is a 10-person crew working Chicago-area chimneys under a founder who built the company’s operating standards from the ground up, with documentation and material standards applied on every job.

Contractor licensing appropriate to the work and the jurisdiction — documentation available on request before any job begins.

General liability insurance — homeowners can request confirmation of coverage before any work begins.

Building permits filed for all code-required work — liner installs, fireplace construction, removal — with the authority having jurisdiction for your address, inspection scheduled, and the passed inspection record delivered at close-out.

NFPA 211 standards followed on every inspection, under the applicable local building code; permit history is a verifiable public record that travels with the home.

HOW WE WORK A JOB

Consistent Field Standards on Every Visit

Cleaning, repair, or full restoration — the crew follows the same standards.

Written condition documentation on all accessible components — including findings the homeowner didn't ask about.

Top-down work sequencing — structural issues addressed before waterproofing, waterproofing before cosmetic work.

Era-matched materials on older Chicago homes — lime joints receive a lime-matched repair, not Portland cement over-tuck.

Substrate verification before any sealer or adhesive — no product goes onto a surface that hasn't passed the pre-application check.

Permit filing for all code-required work, with the correct municipal department and the inspection scheduled as part of close-out.

The core commitment underneath all of it: a written record of every visit — findings, work performed, and anything flagged for follow-up — delivered to you at job close, not a verbal summary at the door. The same crew handles follow-up, at the same number, with no hand-offs to a different team.
WHERE WE WORK

Where ChimTech Works Across Chicagoland

ChimTech is a service-area business covering Chicago and the surrounding counties — the crew travels to the property, and there is no showroom to visit.
Cook, DuPage, Lake, Will, Kane and McHenry counties are all on the regular schedule, with the heaviest concentration in the pre-1940 bungalow and two-flat corridors. Give us the address and we can confirm coverage on the call.
