Garmat Service
Garmat Paint Booth Service and Repair
Independent service for Garmat booths. Heat, airflow, controls, and seals diagnosed and repaired on-site in Denver, Dallas–Fort Worth, and Tampa Bay.
What we do
What we do on Garmat booths.
Garmat booths are common in collision shops, usually as downdraft or semi-downdraft cabins with an air make-up unit and heat package. Like any booth, the airflow, burner, controls, and seals need a specialist's eye as the hours add up. Control generation, burner make, and damper style vary by install year, so we diagnose the booth in front of us.
Spray Booth Services provides independent service for Garmat booths, along with all makes and models. We're a division of John Baker Sales, in business since 2003, and paint booths and the compressors that feed them are all we work on. Whether you need a repair or scheduled maintenance, we'll find the real cause and explain it in plain terms.
What we handle
Heated downdraft airflow
Balance and velocity restored across the cabin, with pressure measured rather than guessed.
AMU & burner
Air make-up heat, slow heat rise, and burner lockouts diagnosed and repaired.
Controls, relays & sensors
Drifting sensors, worn relays and contactors, and interlock faults traced to the cause.
Door seals & gaskets
Leaks fixed so the booth holds pressure and keeps shop dirt out of the finish.
Filtration
Correct media fitted, frames sealed, and airflow restrictions cleared.
Preventive maintenance
Scheduled service so small issues don't become downtime.

How a service visit works
From first call to a booth that runs right.
You call or send the form
Call (888) 912-6684 or use the request form. Tell us it's a Garmat booth, what it's doing, and when it started. A photo of the data plate helps.
We respond within one business day
Every request gets a reply within one business day so we can ask the right questions and set a time.
On-site diagnosis
A technician checks airflow, filters, heat, dampers, and controls on your booth as it's actually configured, not from a generic spec sheet.
Clear explanation and quote
We walk you through what we found, what it takes to fix, and what can wait. You approve before work starts.
Repair or schedule
We fix it on the visit when we can, or schedule the repair, parts, or maintenance around your production.
Common Garmat booth problems
Most Garmat problems surface slowly, as a booth that takes longer to heat or puts more dirt in the clear, before anything stops working. The usual patterns:
- Slow heat rise, from loaded intake filters, a slipping supply fan belt, a dirty heat exchanger, or a damper not reaching its bake position.
- Hard starts and lockouts, from fouled flame sensors, ignition electrodes out of position, or gas pressure that isn't right at the train.
- Dirt in the paint even with fresh filters, usually the cabin envelope or pressure balance rather than the filters.
- Dampers that don't fully travel, which hurts both pressure balance and gas use.
- Temperature that hunts instead of holding, often sensor placement or control tuning.
Our article on Garmat booth service goes into each of these in more detail.
What you can check yourself
Some of this is shop-level work you don't need a technician for:
- Read and log the manometer at the same time each day. The trend matters more than any one number.
- Change intake and exhaust filters on readings and a schedule, not on complaint.
- Keep floor grates clear and the cabin swept.
- Wipe light lenses and note any that look yellow or dim.
- Listen for new fan noise and check that belts aren't slipping.
- Inspect door seals for tears, flattening, and gaps.
Logging the manometer is the cheapest early warning you have. See how to read a paint booth manometer.
When to call a technician
Call for anything involving gas, high voltage, interlocks, or measured airflow: repeated burner lockouts, temperature that won't hold, a noisy or vibrating fan, dampers that don't travel, control faults you can't clear, or dirt in the paint that persists after fresh filters. Those are paint booth repair jobs. Never bypass an interlock to keep a booth running.
If you're not sure how much life is left in the booth, a Booth Health Check gives you a technician's view before you budget. Smart Filter Monitoring can email you when filter airflow says it's time to change.

Questions & answers
Garmat booth service questions
Why is my Garmat booth taking so long to heat up?
Most often loaded intake filters, a slipping supply fan belt, a dirty heat exchanger, or a damper not reaching its bake position. Change filters first, then have air handling and damper travel inspected.
What causes dirt in the paint even with new filters?
Usually the cabin envelope or pressure balance: door seals, light fixture gaskets, panel joints, or a booth not holding its intended pressure against the shop. See dirt in your finish.
How often should a Garmat booth be serviced?
Filters change on usage, often monthly or sooner in a busy collision shop. A full professional pass on the burner, fans, belts, dampers, controls, and interlocks is typically once or twice a year depending on booth hours. Follow your manual if it says otherwise.
Are you a Garmat dealer or authorized service center?
No. Spray Booth Services is an independent service company. We are not affiliated with or endorsed by Garmat, and we'll tell you if something needs to go back to the manufacturer.

Yes. We work on booths regardless of who sold or installed them.
