Violations on a hood system tend to be specific and fixable. We take the inspector's list, make the corrections in the hood, duct or fan, and document what was done.

Hood and ventilation problems we solve for Woodridge kitchens
A commercial hood is a system, not a box on the wall: the canopy, the welded grease duct, the roof fan, makeup air and a fire suppression system all have to work and pass inspection together. We install that system for restaurants, cafes, bakeries and institutional kitchens in Woodridge, built to NFPA 96 and the village's mechanical code.
Converting a non-food space into a kitchen
Converting a space that never had cooking means routing duct through floors or roofs that weren't built for it. We work out a path that meets clearance and access rules.
Adding a fryer or charbroiler under the wrong hood
New equipment that makes grease or smoke needs a Type I hood that covers it with the right overhang. If the old hood is too short or the wrong type, we extend or replace it.
Duct too close to combustibles
Grease duct needs clearance to wood framing and other combustibles, or an approved enclosure or wrap. We correct runs that were installed too tight.
Grease odor reaching neighbors
Complaints about smell from the roof fan are often a termination problem. We check the height and distance from intakes and correct the discharge.
School, church or daycare kitchen upgrade
A school or church kitchen that starts cooking real meals may need a Type I hood with suppression where a Type II used to be enough. We sort out which applies.
Grease dripping from the hood or fan
Drips at the canopy edge or stains on the roof around the fan are a fire and roof problem. We check filters, joints and the fan's grease box and correct what's leaking.
Smoke rolls out past the hood
Smoke spilling into the kitchen means capture has failed. Common causes are too little overhang, a tired fan belt or a building starved for replacement air.
Scope of work
- Site survey and equipment reviewA walk of the kitchen and roof with your equipment schedule in hand, to see what the system has to cover.
- System design and sizingHood length and type, exhaust volume, duct size and makeup air are sized to the equipment and cooking load.
- Permit drawings and plan reviewWe prepare the permit set and answer plan review comments from the building and fire officials.
- Grease duct installationWelded, liquid-tight grease duct with cleanout access, sloped toward the hood and kept clear of combustibles.
- Exhaust fan installationRoof fan set, hinged for cleaning access and fitted with a grease collection box.
- Makeup airReplacement air sized to the exhaust so the kitchen stays near neutral pressure.
- Start-up and airflow checkFans and makeup air started, balanced and checked so the hood captures smoke at full cooking.
Systems and components
Duct wrap and rated enclosuresFire protection for duct runs that can't keep open clearance to building materials.
Type I hoodRequired over cooking that makes grease-laden vapor; it connects to a welded grease duct.
Type II hoodUsed where the load is steam or heat, not grease; it can use lighter duct.
Wall canopy and island hoodsWall hoods sit against a back wall over a cook line; island hoods hang over a free-standing line and need more overhang.
Makeup air unitA rooftop or interior unit that brings in fresh air to replace what the hood removes.

Commercial Kitchen Hood Installation questions from Woodridge businesses
What code does a commercial hood have to meet?
NFPA 96 is the standard for commercial cooking ventilation, adopted alongside the mechanical code your village enforces. It covers hoods, grease duct, clearances, fans and suppression.
Who approves a new restaurant hood in Woodridge?
In Woodridge, approval runs through building or mechanical plan review, the fire prevention side and, for new food service, the health department.
What does a commercial hood installation cost?
It varies widely with the equipment and the building. After we see the kitchen and the roof, you get an itemized proposal.
Who installs and services the fire suppression system?
Suppression is installed and serviced by a licensed suppression contractor. We coordinate the hood, piping access and interlocks with them.
Why do I need makeup air?
A hood can only exhaust as much as the room can replace. Makeup air sized to the exhaust is part of the system, not an extra.
What is the Woodridge building department phone number?
Permits go through Village of Woodridge Community Development Department (Building Permits), phone 630-719-4750. When your scope needs one, we prepare the application and schedule the inspections.
Which Woodridge office signs off on hood work?
Fire service is provided by fire protection districts (Darien-Woodridge, Lisle-Woodridge, Lemont) depending on address. We schedule the inspection and have the paperwork ready.
Woodridge contractor registration: do kitchen contractors need it?
Contractors register with the Village at no fee; a certificate of insurance naming the Village is required before a permit is issued ($100,000/$300,000 public liability, $50,000 property damage). We take care of that before work starts.

Yes. Our crews work across Woodridge, including Seven Bridges, The Ridge — ZIP 60517, 60439 — and nearby Downers Grove, Lisle, Bolingbrook.
