Washroom sealing in Kimpton, done properly
When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. Site teams most often ask us about a new bead over an old one coming away and black mould inside silicone joints that cleaning can’t shift, across IPS panels and cubicles, vanity units and basins and urinals and WCs. Looking for mastic applicators who cover Kimpton? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Smaller places such as Kimpton still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould usually can’t be cleaned, so it is cut out and replaced.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Washroom sealing around Kimpton: how the place shapes the job

Schools such as Kimpton Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays.

Near you in Kimpton

What we’re called out for in Kimpton
A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old so it peels away quickly.
It’s worth sending us details if you spot any of the following:
- Split or peeling sealant at shower trays
- Gaps where vanity tops meet the wall
- Open joints at the base of cubicle panels
- Resealing that didn’t last because the old bead stayed
Where you are responsible for a hall attached to a building such as Parish Church of St Peter and St Paul, its kitchen and toilets need sealant that stays cleanable.

Other services in Kimpton
Work for main contractors and building owners
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Leave it or put it right?
A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. Older rural buildings around Kimpton move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Questions we are asked in Kimpton
Is Kimpton off your patch?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Will all the washrooms in our Kimpton building be closed at once?
Normally only some of them, for a short time. We work in phases so other facilities stay open. Each area is handed back once the sealant has cured enough to use.
What sealant do you use in washrooms?
An anti-mould sanitary silicone for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Do you do washroom sealing in healthcare settings?
Yes, healthcare and care settings are part of our work. Tell us what records you need and we will confirm with the quote before we start.
What guarantee comes with washroom resealing?
A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.
Diagnose, treat, sign off
Diagnose, treat, sign off: that’s the shape of every visit.

Before quoting, we check that sealant is the right answer. It isn’t the answer for:
