Hey wondering if any of you guys have experienced something like this...
I've been noticing an odour coming from the top 5-6 steps of the basement stairwell. It just smells like garbage and sewer sometimes. No smell in the actual basement or main floor of the house, it's restricted to just the stairwell.
Reading online that it could be plumbing vents that are blocked/cracked. Big expenditure coming soon?
Recommend any plumbers?
