About our washroom sealing in Harlington
Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so there are always facilities in use. Tell us your site hours and access windows and we will plan around them. Site teams most often ask us about failed sealant behind washroom basins and failed sealant in a tea point or staff kitchen, on urinals and WCs, accessible toilets and changing rooms and kitchens and tea points. Most enquiries from Harlington start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
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.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Busy facilities in and around Harlington
London offices and hotels usually can’t close all their washrooms at once, so resealing goes floor by floor, agreed with the facilities team. Harlington has plenty of hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later.
Toilets at colleges like Hayes College London (1.6 miles north-east of Harlington) take heavy use from students and staff alike. In a centre such as Lombardy Retail Park (2.5 miles north-east of Harlington), public washrooms are resealed a block of facilities at a time. If you manage an office at a site such as Eastern Business Park (0.9 miles south-east of Harlington), the washrooms and tea points can be done a floor at a time.
Harlington is about 2 miles south-east of West Drayton, in Greater London. Anywhere in UB3, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Greater London coverage takes in 764 places, large and small. For work in that direction, see our London page (15 miles or so).

What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Panel boards already damaged by water
- Fittings that move too much to hold a bead
- A room that stays damp because ventilation isn’t working
Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

Cost factors for washrooms and wet areas
To price the job, we consider:
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
- Induction, permit and paperwork requirements
- Removal of failed or old sealant
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Details that help us quote
We can often quote from photographs and a few details. It helps to include:
- Drawings or a marked-up plan, if available
- Where the site is, with the postcode
- What the building is and how it’s used
- Any specification or named product
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Site staff or a sealant specialist?
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.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
Keeping the joints sound
After handover, these steps help:
- Don’t leave trays and floors sitting wet
- Report split joints at trays and basins early
- Add sealant joints to planned maintenance checks
- Photograph and log failed joints across the estate
Include sealant joints in your planned maintenance checks. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and photograph anything new.
Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.
For managing agents and facilities managers
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Harlington can form part of a wider programme across Greater London.
Questions we are asked in Harlington
Will our hotel in Harlington need to close for the work?
In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Can you work around term dates at a campus such as Brunel University of London?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
What happens if old sealant might contain asbestos?
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.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member.
