Grease Duct Cleaning in Houston, TX
Houston Quality Hood Cleaning cleans commercial kitchen grease ducts in Houston, TX, following the full exhaust path from the hood collar up to the rooftop fan. Grease that gets past your filters cools and sticks to the duct walls, often in sections nobody on the cook line ever sees.
- Ducts cleaned to bare metal, from the hood collar to the rooftop fan
- Before-and-after photos, a written report and a dated certificate after each visit
- Single-hood full-system visits typically run $150–$500, quoted in writing first
We open the access panels, scrape and pressure-wash the interior to bare metal, and photograph each section before and after. You get a written report your fire marshal and insurance carrier can actually read. Houston Quality Hood Cleaning provides grease duct cleaning to Houston and surrounding cities, including Pasadena, Bellaire, Pearland, Sugar Land, Katy and Humble.

Grease Duct Cleaning by System Type
Every duct system is built a little differently. Here are the four we see most in Houston kitchens.
Vertical Grease Duct Risers
Most restaurants send exhaust straight up through the building to a fan on the roof. Grease clings to the riser walls the whole way, and the thickest layer usually sits just above the hood where the air first cools.
We clean the riser from both ends, working down from the roof and up from the hood, so nothing gets missed in the middle.
Horizontal Duct Runs
Strip centers and converted spaces often route the duct sideways before it turns up. Grease pools in those flat stretches like water in a gutter, and that's where we find the heaviest buildup.
We work through every access panel along the run and note any spot where a panel is missing or a section can't be reached.
Multi-Hood Duct Systems
Hotels, hospitals and schools often tie several hoods into one larger duct. Each branch picks up grease at a different rate, depending on what's cooking below it.
We clean every branch and the shared trunk in one visit, then list each one separately on your report so you can see which line runs dirtiest.
Charbroil, Wok and Solid-Fuel Ducts
Charbroilers, woks and smokers throw off heavy, sticky grease that hardens fast. A duct over a mesquite grill builds up much faster than one over a steam table.
These ducts usually need hand-scraping before the pressure wash will do much. NFPA 96 puts solid-fuel systems on a monthly schedule, and high-volume charbroil and wok lines on a quarterly one.
Grease Duct Cleaning Process
Step 1: Protect the Kitchen and Roof
Cooking equipment and floors get covered. On the roof, containment mats and drain covers go down before any water is sprayed.
Step 2: Open and Photograph
We open each access panel and photograph the duct interior, so your report shows the starting condition.
Step 3: Scrape, Degrease and Wash
Hardened grease is scraped by hand. Then degreaser and pressure washing take the duct down to bare metal.
Step 4: Inspect and Report
Panels are resealed and the fan is tested. You get after photos, any damage we found and a dated certificate.

Grease Duct Cleaning FAQs

NFPA 96 ties the schedule to cooking volume and fuel: monthly for wood or charcoal, quarterly for high-volume kitchens like 24-hour, charbroil or wok, twice a year for most standard restaurants and once a year for light-use kitchens. The duct is cleaned on the same schedule as the hood.
No. The duct is where hidden grease builds up, and a cooktop fire that reaches it spreads quickly and is much harder to put out. NFPA 96 calls for grease removal along the entire exhaust path.
A full system with one hood usually takes two to four hours. Long runs, several hoods or a duct that hasn't been touched in a year can take longer. We schedule around your service hours.
Duct cleaning is priced as part of a full-system visit. Most single-hood kitchens pay $150–$500, and large multi-hood systems run $600 or more. Duct length, roof access and how much grease is in there move the price.
We'll tell you which section, why it can't be reached and where it is, in writing. Missing or sealed access panels are common in older Houston buildings, and your report will show exactly where they are.
It shouldn't. We put containment mats and barriers around the fan, cover the drains, and collect and dispose of the grease and wastewater.
