Every small town restaurant, sweet shop, dhaba, and marriage banquet hall struggles with suffocating kitchen smoke, grease fumes, and blistering stove heat. Building and installing customized exhaust duct systems solves their major regulatory and operational nightmare. You set up sheet metal shearing and folding benches, spot welders, and stock stainless steel and galvanized steel sheets. You visit local eateries, calculate air changes based on kitchen volume and burner counts, and fabricate tailor made grease hoods and duct pathways. Connecting these to rugged rooftop centrifugal exhaust blowers pulls away hot oil vapors and smoke instantly.
Restaurant owners happily pay for installations because it keeps their cooks productive and satisfies local food safety and municipal fire inspectors. Regular duct cleaning contracts provide continuous recurring revenue.

Expanding numbers of eateries, sweets makers, and event banquet kitchens face severe ventilation issues and stringent municipal health guidelines. Tailored sheet metal duct networks connected to industrial blowers extract greasy soot, improving kitchen comfort and fire safety.
Small town restaurant, sweet shop and dhaba owners setting up a new kitchen or replacing a smoke-choked one who need a properly sized exhaust hood before a Food Safety Officer's first inspection. Marriage banquet halls building or renovating a kitchen for large-volume cooking are a bigger single job, since their cooking loads and duct runs are far larger than a small eatery's.
They decide to pay when a health inspection flags inadequate ventilation, when staff refuse to keep working in a smoke-filled kitchen, or when a new kitchen is being built from scratch and the owner wants to pass inspection the first time.
Charge per project for fabricating stainless steel grease hoods, running galvanized duct to the roof or outer wall, and installing a centrifugal blower sized to the kitchen's cooking load, priced by the length of duct run and the size of the hood. A separate, smaller recurring income stream comes from offering scheduled cleaning of the hood, filters and duct, since grease buildup inside ducting is flagged as a fire hazard and hygiene violation that inspectors and fire departments check for.
Professional duct cleaning is commonly priced in the range of three thousand to eight thousand rupees per session, with heavy frying operations needing it monthly and standard kitchens quarterly. A typical project is a full hood, duct and blower installation as a one-time job, followed by a maintenance contract that brings the same customer back every three months.
General sheet metal fabricators can weld a hood shape but often size the duct and blower incorrectly for the actual cooking load, leaving a kitchen still smoky despite having a hood installed. Few local contractors offer a scheduled cleaning service afterward, leaving grease to build up quietly until an inspection or a fire exposes it. Your edge is sizing the exhaust system correctly to the cooking load from the start, using proper food-grade stainless steel where it touches food-contact areas, and following up with a cleaning schedule that keeps the same kitchen as a customer for years rather than a single job.
Perfect for experienced sheet metal fabricators and ventilation technicians looking to capture commercial kitchen budgets. Not for people afraid of heights or dirty duct interiors.

Sheet metal fabrication tools including a bending brake, shears and a welding or riveting setup for stainless steel and galvanized sheet, a portable measuring and layout kit for on-site duct runs, ladders and roof access equipment, and a centrifugal blower supplier relationship for sourcing the right size unit for each job make up the core costs. Grade 304 food-grade stainless steel is the standard material expected for kitchen contact surfaces and hoods in FSSAI-compliant kitchens, so sourcing a reliable supplier of this grade sheet matters more than sourcing the cheapest option.
We found no published total setup cost for a kitchen ducting and exhaust contracting business in India.
Every small town restaurant, sweet shop, dhaba and banquet hall needs compliant ventilation to pass food safety inspection, and grease fires are named as the leading cause of kitchen fires in Indian restaurants, with a single incident causing between five lakh and fifty lakh rupees in damages and two to eight weeks of closure, which is the cost your installation and maintenance work protects against. Early income comes from new kitchen fit-outs as small eateries open or renovate; steadier recurring income comes from cleaning contracts once you have installed hoods across a cluster of kitchens in town.
We found no published earnings figure for this specific trade in India, and the number of installation jobs you can complete in a month, alongside how many cleaning contracts you can service on a rotation, caps how far it grows.

Set up sheet metal fabrication tools for stainless steel hoods and galvanized duct runs, including bending, shearing and welding or riveting equipment.
Build a relationship with a centrifugal blower supplier who can advise on sizing for different kitchen loads.
Visit restaurants, sweet shops and dhabas that are currently renovating or newly opening to offer a compliant installation.
Approach banquet halls directly, since their larger kitchens make them a bigger single project and often more safety-conscious.
Offer a scheduled cleaning service alongside every installation, quarterly for standard kitchens and monthly for heavy frying operations.
Keep a maintenance record for each client kitchen so cleaning visits are scheduled and tracked without relying on the owner to remember.
A new kitchen fit-out job can come within weeks of introducing yourself to a restaurant or sweet shop that is currently renovating or opening, since ventilation is one of the first things a Food Safety Officer checks and owners want it right before inspection. Building a base of scheduled cleaning contracts takes longer, usually following a successful installation job that earns the owner's trust. Approaching banquet halls directly, since their larger kitchens and higher stakes make them proactive about compliance, can bring in bigger single projects faster than waiting for small eateries to call.
FSSAI kitchen guidance, as summarised by Riddhi Display, requires every cooking station to have proper ventilation. In practice that means sizing the hood, filters and duct to the burners or tandoors it actually serves, not fitting a generic standard size. An undersized system leaves smoke and heat in the kitchen despite having a hood installed, so get it right before the first inspection.
Standard kitchens generally need duct and hood cleaning every three months, while heavy frying or tandoor operations need it monthly because grease builds up faster under that kind of cooking. Grease reaches its ignition point at around 340 degrees Celsius, a temperature tandoor kitchens can easily exceed, which is why regular cleaning is treated as a fire safety requirement rather than just a hygiene one. FSSAI and fire departments generally expect cleaning records to be kept.
Professional duct cleaning is commonly priced in the range of three thousand to eight thousand rupees per session, with monthly service for heavy-frying establishments often falling in the three thousand to five thousand rupee range. Pricing depends on duct length, grease buildup and kitchen size. Offering this as a standing contract rather than a one-off call gives you predictable recurring income.
Grade 304 food-grade stainless steel is the standard expected for surfaces that contact food or sit close to the cooking area in FSSAI-compliant kitchens, since it resists corrosion and does not contaminate food. Using a lower grade to cut cost can fail inspection and needs replacing later at greater expense. Sourcing a reliable supplier of the correct grade sheet is worth the extra effort.
Grease fires are named as the leading cause of kitchen fires in Indian restaurants, and a single incident can cause between five lakh and fifty lakh rupees in damages and force two to eight weeks of closure. Against that risk, a quarterly cleaning contract costing a few thousand rupees is an easy case to make to an owner. Framing your maintenance service around this risk, rather than just cleanliness, helps close the sale.
