Chapeau !

When we hired the plumbing/heating contractor to work on the new shower stall, we included a few other items in the job. One was replacing a radiator with a towel warmer, another was to install a second outdoor spigot because the original one ended up inside the greenhouse. Also included was the installation of a cap on the chimney that comes up from the ventilation hood over the kitchen stove.

A chimney cap is called "un chapeau" (a hat) in French.

There are three chimneys on this, the south end of the house. One was for the central heating oil-fired boiler. That one is no longer in service with the new condensation boiler that vents through a new "hole" in the side of the house. The second is a twin to the stove hood chimney. I'm not sure why there are two in the kitchen; we think there may have been a coal burning heater in there next to the stove, but the second chimney is not in use. The third is the one connected to the current stove hood. Our wood-burning stove has its own capped chimney on the north end of the house.

We noticed last year, after a particularly hard rain event, that water seeped through the kitchen flue to the dry-wall where the stairs go up to the loft (close to the roof). We think that water got into the chimney, since they are open to the weather. So, the contractor sealed the two unused chimneys and added this cap to the third.


  1. Was the range hood exhaust routed up the chimney when you bought the place? If not, how on earth did you convince the plumber to do it? We tried and tried and they all just say it's illegal (which it isn't if the chimney is not in use for a fire, but they clearly don't want to do it).

  2. A chimney cap seems like a good idea even without rain considerations, as it will keep birds and small critters from entering or nesting.

    1. One summer we found a small bat in our woodstove in the living room. It had come down the chimney, I guess.

  3. susan, no, it was not because there was no exhaust fan installed. Just the bottom of the flue, exposed under the hood. We had an electrician install the hood fan/filter/lighting unit and he connected it to the flue with no questions.

    emm, there is a piece of wire mesh over the chimney that kept the critters out (but not the wasps). It's still there and you can see it in the photo if you enlarge it.


Pour your heart out! I'm listening.
