Washroom sealing across Kennington
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking half a day to a day per washroom, depending on the number of fittings. Planning a London job such as one in Kennington starts with access. Send the building rules and access times with your enquiry.
- We survey each room, count the joints and note anything behind them that needs another trade.
- We agree which rooms close and when, so users always have somewhere to go.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- Each room is handed back once the sealant has had its cure time.
What we need from you
- Share your working hours and any access restrictions
- Arrange parking or a loading space
- Move anything stored against the joints

Advice
About our washroom sealing in Kennington
From one staff toilet in Kennington to washrooms across a whole estate, the route is the same: send details, get a fixed quote, we seal, guaranteed. A few photos and a count of fittings are enough for a quick quote, or we can arrange a visit. We work on urinals and WCs, showers, trays and wet room floors and vanity units and basins, and the usual reasons a site gets in touch are sealant laid over old silicone and now peeling and failed sealant behind washroom basins. Whether you call it commercial sealant work, mastic application or joint sealing, in Kennington it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Leave it or put it right?
Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
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 you’ll have a fixed figure to work with.

Questions we’re asked in Kennington
Is hospital work, at somewhere like Gordon Hospital, something you do?
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 you plan work around the academic year at somewhere like University of the Arts London?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Busy facilities in and around Kennington
Kennington has two care or nursing homes no more than 2 miles away. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. We plan the work with the manager so residents are disturbed as little as possible. London offices and hotels typically can’t close all their washrooms at once, so we take one block of facilities out of use at a time.
If you manage an office at a site such as Handel Business Centre, under half a mile north-west of Kennington, the washrooms and tea points can be done a floor at a time. For a campus such as University of the Arts London (1.4 miles west of Kennington), showers in residences and washrooms in teaching blocks can be programmed around term dates.
Kennington is about 2 miles south-west of London, in Greater London. Looking for washroom sealing in Kennington? We can help. Kennington is one of 764 places in Greater London on our list for washrooms and wet areas.

What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Mould caused by poor ventilation, which will return until the extract is fixed
- Fittings that move too much to hold a bead
- Water escaping beneath the floor rather than through a joint
If in doubt, phone 01277 525 020 or email us and we will say what we think before you book.
Joints and surfaces we work on
- Urinals and WCs
- Accessible toilets and changing rooms

What affects the price in Kennington
Quotes vary with the job. It mainly depends on:
- Induction, permit and paperwork requirements
- How much there is to seal
- Travel to remote or island sites
- Joint width, depth and condition
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Before you send an enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- Access details, including height
- The asbestos register, for older buildings
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or ring 01277 525 020 or email the details over if you’d rather talk the job through.
Signs you need washroom sealing in Kennington
Panels and vanity units move slightly in use and trays shift slightly with each user. A bead that can’t cope with the movement splits along one edge.
Most enquiries start with something like this:
- Sealant laid over old silicone and now peeling
- Black mould inside silicone joints that cleaning can’t shift
- Failed sealant in a tea point or staff kitchen
- Complaints from staff, guests or users about tired washrooms
Colleges such as Chelsea College of Art & Design (0.7 miles north-west of Kennington) have toilets, changing rooms and catering kitchens that can be resealed around term dates.
Questions to ask before you book
- Proof of insurance
- How the existing material will be dealt with
- Do they follow the manufacturer’s priming guidance?
- How they handle RAMS and site documents
Site staff or a sealant specialist?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
