Surface by surface

Office washrooms & kitchens

Staff toilets, washrooms and kitchens get constant use, so the work can be arranged for quieter times. Basins, urinals, worktops and sinks are all resealed.

Hotel bathrooms

Hotel showers and baths get used and cleaned every day, so joints are finished smooth and sealed with anti-fungal sanitary silicone.

Commercial sealant for homes and businesses in Bromley Common

Mouldy or split sealant in a commercial building causes more than a bad impression. It’s a cleaning problem, a leak risk and something guests and staff notice. We reseal bathrooms, washrooms, welfare areas and kitchens so they look cared for again. If you have failed joints in office kitchens and tea points and mouldy washroom sealant that staff and guests notice, we can put it right.

London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Bromley Common needs to stay open, work can be planned outside normal hours.

There’s a 12-month guarantee on every job, whatever its size.

How to look after the new joints

A little care helps the new joints last. Our advice:

  • Give housekeeping the cure time for every room
  • Check the joints during routine room inspections
  • Schedule work around occupancy
  • Report broken fans quickly

Each room is handed back with its cure time, generally around 24 hours. Pass it on to housekeeping or cleaners so nobody showers or cleans the joint too early.

A room that cannot be let or used is lost income. Small sealant faults caught early can be fixed between bookings or tenancies, instead of turning into a leak that closes the room.

Why it’s worth doing now in Bromley Common

A leaking shower in a hotel room or flat above can damage the ceiling below. That means a second room out of use and a repair to pay for. Resealing first is the smaller job. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Bromley Common, the repair is bigger than a sealant job.

A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

Why us?

  • We never seal over old sealant
  • Rated 4.9 stars on Google
  • A sealant colour to suit the surroundings
  • ARBOMaster approved applicator

Common problems we fix in Bromley Common

Internal washrooms and en suites without a window rely entirely on extraction, and where extraction is poor, damp hangs around. That’s when black mould sets into the bead.

These are the problems we’re asked about most:

  • Tired sealant ahead of a health and safety audit
  • Mouldy bathrooms flagged at a tenancy check
  • Water marks on ceilings under bathrooms
  • Sealant failing again soon after quick repairs

If you look after a building such as Trinity Church of England Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

What your quote should include

  • Is VAT in the price?
  • Who turns up on the day
  • When the joint can take water or movement
  • Which sealant they’ll use, and why

Advice

DIY sealant or a professional job?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
