Your furnace and water heater vent through the chimney too. Brown Chimney cleans that flue, replaces the connector pipes between the appliance and the liner, and installs aluminum liners for gas appliances. We do not install or service the appliances themselves.

Flue cleaning and pipe reconfiguration are flat-priced. Pipe replacement and the aluminum liner depend on length, height and access, so those two are measured on site and confirmed in writing before any work begins.
A gas furnace or water heater that vents into a masonry chimney sends cool, acidic exhaust up the flue. That exhaust condenses on the walls and eats mortar joints and clay tile faster than a wood fire does, which is why these flues deteriorate quietly for years before anyone looks inside. In Detroit's older brick housing stock, many of these flues have never been lined for a gas appliance at all.
Brown Chimney handles the chimney side of that system in Detroit. We clean the furnace and water heater flue, check the liner and joints, and replace or reconfigure the connector pipes between the appliance and the chimney. Where a chimney has no liner suited to a gas appliance, we install an aluminum liner sized for it.
Installing, repairing or servicing the furnace or water heater itself is not something we offer. A licensed HVAC or plumbing contractor handles the unit. We make sure the chimney it vents into is clean, sound and correctly connected.
Connector pipe from a gas water heater into an aluminum-lined masonry flue — Detroit, MI
Flue cleaning (CLN-009): The flue is cleaned and vacuumed from the appliance connection to the top, cap clearance is checked and the liner and joints are visually checked. $300. Appliance service is not included.
Pipe reconfiguration (VNT-002): Exhaust pipes between the appliance and the liner are disconnected, repositioned, fitted with new connectors where needed, then reconnected and sealed. $350–$650 depending on configuration and access.
Pipe replacement to liner (VNT-003): Old connector pipes between the furnace or water heater and the chimney liner are removed, new pipe installed and all connections sealed. Priced on site by pipe length, material and access.
Aluminum liner for gas appliances (LNR-002): A new aluminum liner sized to the appliance, for flues that are unlined, oversized or damaged. Up to 20 ft $2,500 · 20–30 ft $3,500 · over 30 ft $4,500.
If the flue needs more than a liner, see our Detroit chimney liner relining and chimney inspection pages, or return to the Detroit services page.

The best installations are boring. Measured right, vented right, tested before we leave — and then it just works, every winter, for years.
The visit starts at the appliance connection and follows the flue to the top. The five steps below cover the inspection, the written price, cleaning, any pipe or liner work and the final check.
01
The connector pipe, draft hood and the point where the pipe enters the chimney are inspected for rust, gaps, slope and loose joints.
02
Liner condition, joints, cap clearance and the flue size relative to the appliance are checked along the full height and photographed.
03
Flue cleaning and pipe reconfiguration are flat prices from the price book. Pipe replacement and any aluminum liner are measured and written down before work starts.
04
The flue is cleaned and vacuumed, connector pipes are replaced or rerouted, and an aluminum liner is installed where the flue needs one for the gas appliance.
05
Every joint is sealed and the appliance draft is checked before we leave, so exhaust goes up the chimney and nowhere else.
Flue cleaning and pipe reconfiguration are flat prices from our published price book; nothing is added on site.
Pipe replacement and aluminum liners are measured on site and confirmed in writing before any work begins.
Pipe and liner labor carries our 1-Year Workmanship Warranty. Cleaning is not covered. Appliance work is not included.
