Safe, chemical-free ways to clear blocked sinks, baths and showers — and when to call a professional.
You can unblock a sink or shower without chemicals by plunging the plughole to shift the blockage, or by removing and cleaning the u-bend trap where hair, grease and soap scum collect. For a stubborn or recurring blockage, professional extraction is the safest chemical-free option, because it removes the obstruction completely without the risk that corrosive drain cleaners pose to your pipes.
A+ Drainage Services clears blocked sinks, baths and showers across Essex, London and the M25 corridor using safe, professional methods rather than harsh chemicals, all with zero callout fees. Here is what causes these blockages and how to clear them safely.
Blockages inside the home build up from everyday use. In kitchen sinks, the usual cause is cooking fat and food debris cooling and hardening inside the pipe. In bathrooms, it is hair binding together with soap scum in the trap and narrow waste pipes. Over time these deposits form a solid mass that restricts water flow, slows draining and produces unpleasant odours.
Several safe, chemical-free methods can shift a minor blockage:
A cup plunger creates suction and pressure to dislodge a blockage close to the surface. Cover any overflow hole first.
Place a bucket underneath, unscrew the u-bend and clear out trapped hair, grease and debris by hand.
Lifting the grate lets you pull out the matted hair that is usually the culprit in showers and baths.
A drain snake or plumber's auger can reach and hook out a blockage further down the waste pipe.
If these steps do not restore the flow, or if the blockage keeps returning, it is time to call a professional rather than reaching for chemicals.
Boiling water can temporarily soften minor grease build-ups, but it rarely clears a solid obstruction. It also carries a risk: pouring boiling water directly into cold PVC pipes or a ceramic basin can occasionally cause the pipes or basin to crack. For anything more than a very minor slow drain, it is safer to have the blockage physically removed.
A shower or bath that keeps blocking is almost always caused by hair and soap scum binding together in the trap. Over time, this forms a solid, matted blockage that restricts water flow and causes lingering odours. Because the blockage is physical, it needs to be pulled out rather than dissolved, which is why chemical cleaners so often fail to fix it for good.
Shop-bought chemical drain cleaners are harsh and corrosive. They can melt or damage PVC pipes, they release unpleasant fumes and they frequently fail to shift a solid blockage such as matted hair. At A+ Drainage Services, we never pour chemicals down your plugholes. Instead, we use professional manual tools to safely remove the blockage, protecting both your pipes and the environment.
Because we are working inside your home, we treat your property with care, wearing shoe covers, protecting surfaces and guaranteeing a spotless, sanitised finish. Our process is straightforward:
We assess the affected sink, bath or shower to determine whether the blockage is in the trap or further down the internal waste pipe.
We dismantle pipework where necessary and use professional manual tools to remove hair, grease and debris, never harsh chemicals that can damage your pipes.
Once cleared, we run water through the system to confirm perfect flow, check for leaks and thoroughly clean the work area before we leave.
Common questions about blocked sinks, baths and showers.
The most common cause of a blocked shower or bath is a combination of hair and soap scum binding together in the trap. Over time this creates a solid, matted blockage that restricts water flow and causes unpleasant odours.
Hot water can temporarily soften minor grease build-ups, but it rarely clears a solid obstruction. Pouring boiling water into cold PVC pipes or ceramic basins can occasionally cause them to crack, so it is always safer to have the blockage physically removed.
