Bathroom Sealant Services Manchester
You see it every day. The black line around the bath. The sealant that has cracked along the shower tray. The corner that has lifted and lets water sit behind it. It looks bad and it causes real damage if it is left too long. BrightWhite UPVC Cleaning Services removes old sealant fully and applies a clean fresh seal around baths, showers, tiles, wet rooms and basins. The bathroom looks right again and the water stays where it should.
Why Old Sealant Cannot Just Be Painted Over
A lot of people try to fix black sealant by putting a fresh layer on top of it. It looks better for a few weeks. Then the black starts coming back through. That is because the mould is not sitting on the surface. It is living inside the sealant and behind it, between the sealant and the wall.
New sealant laid over old does not bond properly either. The old surface is already dirty and breaking down. The new layer has nothing clean to grip onto. It starts to lift at the edges within weeks and the whole job needs doing again.
The only fix that lasts is taking the old sealant out completely. Clean the surface back to bare material. Let it dry fully. Then apply fresh sealant on a clean base. That is the difference between a repair that holds and one that fails quickly.

How the Job Gets Done
Full Removal
Every trace of the old sealant is cut back to the bare surface using purpose-made removal tools. We do not scrape over it or lay anything on top. The joint is cleared fully before we do anything else.
Surface Preparation
The area is dried fully and wiped down to remove any mould residue before the new sealant goes on. This is the step most people miss when they try it themselves. Skipping it is why the mould comes back.
Fresh Application
The new sealant goes on in one continuous bead, pressed to a flat smooth finish and left to set properly. Tiles stay clean. Fittings stay unmarked. The finished line is straight and sits flush with the surrounding surface.

Frequently Asked Questions
Surface mould can be treated but if it has grown into the sealant and behind it the only proper fix is full removal. Treating the surface alone leaves the mould source in place and it comes back within weeks.
Most bathroom sealants are dry to the touch within a few hours but the area should not be used for 24 hours after application. We tell you the exact curing time for the product used on the day before we leave.
Yes. We carry white, cream, grey and clear. For most standard bathrooms one of these will match. We check before starting so there are no surprises on the day.
With regular wiping down and without bleach being used directly on it, good quality sealant lasts three to five years. Some lasts longer. The key is keeping the line dry and catching any small gaps before they grow
Most bathrooms take one to two hours depending on how much needs resealing. After that the sealant needs 24 hours before the bath or shower is used again. We work around your schedule where we can.
