Toilet or drain blocked in Leidschendam? What you need to know
Soil and sewers in Leidschendam: homes along the Vliet with cellars and older external sewers. Characteristic of Leidschendam: post-war neighbourhoods with many flats, plus older homes along the Vliet.
In stacked buildings, flats often share one soil stack. If the blockage is in there, the lowest flat notices it first. We establish where the blockage is, so it's clear whether the owners' association (VvE) or landlord is responsible. Properties with a cellar, basement or low crawl space lie lower than the street. If the sewer fills up, the water comes up there first; a clear, free-flowing pipe makes all the difference. Older properties often still have earthenware pipes or cast-iron drains. We treat those with care: pushing through too hard can break an old pipe, and a camera shows the condition of the pipe.
What we encounter most often in Leidschendam in this area: blocked external drains. We also often come for leaks in cellars along the Vliet and central heating boiler replacement in post-war homes.
