Grease
Monsters
of San Antonio
We strip kitchen exhaust systems back to bare metal and hand you the paperwork your fire marshal and insurance adjuster actually want to see.
Every layer of grease, handled.
Hood & Plenum Degreasing
Hot-water pressure degreasing of canopy, plenum, and filters down to bare metal.
Duct & Riser Scraping
Hand-scraped vertical risers and horizontal runs from hood collar to fan housing.
Rooftop Fan Service
Belts, bearings, hinges, grease containment. Cleaned, lubricated, documented.
Access Panel Install
Code-required access doors cut and sealed where blueprints fall short.
Exhaust Fan Install
Supply and install rooftop exhaust fans sized to your hood — wired, balanced, and code-compliant.
Compliance Reporting
Photo logs, before/after, and signed certificates for your AHJ and insurer.
From fire hazard to factory finish.
Grease build-up is the #1 cause of restaurant fires. Every job ends in a photo report — so you can see the bare metal we leave behind.

"They did a phenomenal job. Great customer service. I asked about a cleaning on Wednesday and they came out two days later. Super fast and price was excellent. Will be using this locally owned company from now on."
"We recently hired Grease Monsters of San Antonio for a vent hood cleaning, and they absolutely delivered. Fast, efficient, and incredibly thorough — left our kitchen ventilation system spotless. Professional team, arrived on time, and worked with precision. Highly recommend, we'll definitely be using them again!"
"We have used Grease Monster several times and they always do an excellent job. Quality cleaning, service and professionalism. Will continue to use. They even travel an hour and a half to get to us after we closed for the day. They cleaned through the night so we could open at regular hours the next day."
