Washroom sealing for Whitton sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What we’re called out for in Whitton
Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.
Any of the following is a good reason to get the joints checked over:
- Open joints along basins and vanity units
- Discoloured joints around urinals and WC pans
- Washrooms that look worn because of the sealant
- Sealant stained black around basins and showers
For a campus such as St Mary's University, 1.1 miles to the south-east of Whitton, showers in residences and washrooms in teaching blocks can be programmed around term dates.

Washroom sealing in Whitton, done properly
From one staff toilet in Whitton to washrooms across a whole estate, we work the same way: 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 sealant laid over old silicone and now peeling, we can put it right. Whoever orders the work in Whitton, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Building managers in Whitton normally need some facilities open throughout. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand, so staff and visitors can always find an open washroom.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What sets the cost
Before we quote, we look at:
- Location, for remote and island sites
- Site requirements such as inductions and permits
- Quantities, in metres or numbers
- Whether the work must be split into stages
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- The site address and postcode
- How the joints are reached, and at what height
- Whether an asbestos survey exists
- What the building is and how it’s used
For a fixed quote, give us a call on 01277 525 020 or send photos by email with the site address and an outline of the work. Our quote form is another easy route.
Why act early in Whitton
Washrooms shape how visitors judge a building. Visitors notice black sealant even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Pricing washrooms and wet areas depends on how many there are, their condition and the access. Call for a quote.

General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. All of Greater London is in the ULEZ, and kerbside space in Whitton can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- We agree which rooms close and when, so users always have somewhere to go.
- The failed silicone is stripped and every face scraped clean of residue.
- Joints are cleaned, degreased and dried before sealing.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- You get a reopening time for every room, with signage left up until then.
What we need from you
- Tell us which areas need to stay in use
- Point out parking and an unloading spot
- For older buildings, check the asbestos register before work

Whitton: questions and answers
Could you schedule work at a campus like St Mary's University for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is a hospital such as Teddington Memorial Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
How long does a job like this take?
That varies with the scale of the job, though a typical visit normally takes half a day to a day per washroom, depending on the number of fittings. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can you quote from photos?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
Do you work in hospitals, clinics and care homes?
Yes. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.
How do I request 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 photos and a postcode.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Looking after the joints
After handover, a little attention goes a long way:
- Report faulty extraction promptly
- Include joints in routine washroom inspections
- Tell us about infection-control or permit rules before we quote
- Avoid scourers and harsh descalers on silicone
Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.
