Quick answer
We clear accessible external rainwater systems including many hopper-fed downpipes. Hidden internal chutes may need building access or a specialist if blockage is deep inside the wall.
What you need to know
Symptoms include damp on internal walls following rain on upper floors.
External rodding resolves many blockages where pipes are accessible.
We explain limits if the fault is inside boxed-in or structural ducting.
How David White can help
We assess each property individually before recommending work. For do you unblock internal rainwater pipes, that means checking access, roof or gutter condition, and any risks to neighbouring properties.
You can send your postcode and photos for a remote quote in many cases. If the job needs a closer look, we will say so upfront rather than guessing on site.
What to expect on the day
Our team works safely from ladders, towers or MEWPs depending on the building. We protect gardens, paths and driveways where moss or debris may fall, and we clear up when the job is done.
We will confirm timing, access and parking before we arrive so the visit runs smoothly for you and your neighbours.
