    Default Chlorine/Bleach smell in basement

    I'll toss out the problems I'm having to see what people think.

    My basement is mostly finished with one large carpeted room (about 2/3 of the square footage), a smaller unfinished room (where the water heater, heating, sump, etc. are) and a small powder room.

    The stairs to the main floor are also carpeted with the same carpet. These stairs turn 90 degree at a landing about 2/3 up from the basement.

    My basement is fairly dry, in fact the house is generally very dry, especially in the winter when the heat is on. There are vents in the basement ceiling connecting to the same ducts that feed heat to the first floor. I've had a dehumidifier there in the basement for about 3 months (the bucket fills about every 3-4 days) and an air purifier for a year. I also run a fan to move air around.

    What I have been noticing for about 5-6 months or so now is around the top of the stairs down from the first floor and to a lesser extent the basement itself a kind of chlorine/bleach sort of smell. I see no sign of mold and don't notice a lot of dust there. I've recently changed the filters in the heating system.

    Thoughts on what could be causing this?

    I had the same thing...come to find out, I just had a leak in a bottle of bleach...easy fix and didn't take too long to find. Where is your laundry area? Just check things there. Also, do you us bleach toilet cleaner? Check around all of your cleaning supplies, may just be as simple as a bottle of something turned over or cracked.
    Do you have a pool? Where are the chemicals stored?
    I don't know of anything that could cause that odor other than chlorine itself so I would just make sure that all of your bottles are upright and air tight. The bottle that I had leaking was dry to the touch until I took the top off. So, if you have a bottle of bleach in the vicinity take it outside and see if the smell dicipates.
    Good luck! Hopefully, some of the experts on the boards will have more answers for your question!!

    Are you sure this isn't actually the smell of natural gas or LP?

    You may have a minor leak somewhere.
