Washroom sealing in Sundridge, done properly
In a busy washroom, the sealant typically gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. We work on IPS panels and cubicles, showers, trays and wet room floors and urinals and WCs, and what we are called in for most is panel joints letting water behind and stained or open joints at kitchen sinks and worktops. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Sundridge is the same: the right product in a properly prepared joint.
Smaller places such as Sundridge still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is 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 are upfront about that.

When to bring in a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

IPS and cubicle panels
IPS panels and cubicle systems have joints at the wall, the floor and the worktop. They stop water reaching the panel boards.
Urinals and WC pans
Pan and urinal joints face constant cleaning and splashing. Once they discolour or split, they hold odours and look unhygienic.
Why act early in Sundridge
When a washroom looks worn, a refit isn’t the only answer. If the finishes are in good order, replacing the sealant may do much of what’s needed while bigger works are planned. One visit to deal with every failing joint makes more sense than several trips to a place like Sundridge, rather than one at a time. Send photos of each area and we’ll quote for the lot.
Pricing washrooms and wet areas depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Common questions from Sundridge clients
Can you take on a job at a hospital such as Sevenoaks Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will the toilets in our Sundridge building be out of use?
Not all at once. We take one block of facilities at a time. We’ll tell you the curing time for the product before we start.
What’s the quickest route to a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Can you quote from photographs?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Do you offer coloured sealant?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Owners, agents and contractors
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sundridge can form part of a wider programme across Kent.
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Toilets, showers and kitchens around Sundridge
Sundridge is about 18 miles from central London, within the office belt around the capital. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time.
For a site such as Sevenoaks Hospital (3 miles east of Sundridge), sanitary joints in clinical areas need sound, cleanable sealant and a careful method. Schools such as Combe Bank School have toilets, changing rooms and kitchens that are best resealed in the holidays. Where you’re responsible for a hall attached to a building such as Church of St Mary, its kitchen and toilets need sealant that stays cleanable.
Sundridge is about 3 miles west of Sevenoaks, in Kent. Across the TN14 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Sundridge is one of 931 places in Kent on our list. For work in that direction, see our London page (18 miles or so).

Honest limits
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Leaks through tanking or membranes below the finishes
- Mould caused by poor ventilation, which will return until the extract is fixed
- Hollow tiles or loose panels behind the joint
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly.
