Washroom sealing in Northfields, done properly
Whether it’s a single toilet block in Northfields or a programme across several buildings, the route is the same: details first, then a fixed quote, then the work, then the 12-month guarantee. A few photos and a count of fittings are enough for a quick quote and a site visit is an option. If you have open joints along basins and vanity units and washrooms that look worn because of the sealant, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Northfields, that means joint design, primers and backing rod as standard.
In a London area such as Northfields, commercial washrooms in offices, hotels and leisure buildings see constant use. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- A room that stays damp because ventilation isn’t working
- A dripping waste or valve behind a panel
- Hollow tiles or loose panels behind the joint
If you’re not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer.
Surfaces we seal
- Urinals and WCs

What else we do in Northfields
Do you need washroom sealing in Northfields?
Washrooms are warm, damp and full of organic residue, and sealant joints trap all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.
Site and facilities staff are often the first to spot these:
- Sealant laid over old silicone and now peeling
- Sealant stained black around basins and showers
- Washrooms that look worn because of the sealant
- Split or peeling sealant at shower trays
Halls of residence and teaching buildings at universities such as University of West London (Brentford Campus) (to the south of Northfields) are easiest to reseal during vacations.
What to look for in a quote

- Will RAMS and insurance details be available?
- Will failed sealant be removed rather than covered?

Questions we’re asked in Northfields
Must a hotel around Northfields close while you work?
In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Could you schedule work at a campus like University of West London (Brentford Campus) for the vacation?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
How do I request a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
How long does a job like this take?
It depends on the scope, but the work typically takes a morning or so for a small washroom, longer where showers and changing rooms are included. For bigger or phased jobs, we will set out a timescale with the quote.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Our process
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We agree which washrooms close and when.
- Anything behind the joints that needs another trade is flagged.
- Old sealant is stripped and the faces prepared.
- We reseal with the grade suited to each area.
- We confirm reopening times for each washroom.
Getting the site ready
- Point out any areas we must not close
- Confirm the product named in the specification
- Share your working hours and any access restrictions
