About our washroom sealing in East Dulwich
Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. The enquiries we see most involve stained sealant around pans and urinals and split or peeling sealant at shower trays, on showers, trays and wet room floors, vanity units and basins and urinals and WCs. Whether you call it commercial sealant work, mastic application or joint sealing, in East Dulwich it comes down to the same thing: the right product in a properly prepared joint.
In a London area such as East Dulwich, commercial washrooms in offices, hotels and leisure buildings see constant use. 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 covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common problems we fix in East Dulwich
We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting, and they stain, crack or wash out.
Most enquiries start with one or more of the following:
- Open joints along basins and vanity units
- Split or peeling sealant at shower trays
- Mould spotting along silicone joints
- Urinal joints that look unhygienic
In a centre such as Cantium Retail Park, which lies north-east of East Dulwich, public washrooms are resealed a block of facilities at a time.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- Is the sealant right for the movement and the substrate?
- Their approach to joint depth and backing
- How the existing material will be dealt with
Quoting for work in East Dulwich
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Phasing around occupants
- Distance, for remote addresses
- Backing rod, priming and other preparation
- Which sealant the job calls for
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Before you send an enquiry
A few photos plus some basic facts will normally do. Please tell us:
- Asbestos survey details if the building is older
- Approximate linear metres or a joint schedule
- The product your specification calls for
- Your programme or deadline
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to call the office on 01277 525 020 or send photos by email.
Common questions from East Dulwich clients
Must a hotel around East Dulwich close while you work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.
Can you work around term dates at a campus such as King's College London?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Is any job too small?
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.
How a job runs
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly.

Related advice
Doing it in-house
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Why act early in East Dulwich
Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
The price depends on the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.
