Washroom sealing for businesses in Brentham Garden Suburb

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Site staff or a sealant specialist?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

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.

Washroom sealing for commercial buildings in Brentham Garden Suburb

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. Site teams most often ask us about sealant stained black around basins and showers and open joints along basins and vanity units, across urinals and WCs, vanity units and basins and showers, trays and wet room floors. One point of contact handles commercial sealant work in Brentham Garden Suburb from the first photographs to the final walk-round, whether it’s one building or several.

Washrooms in London offices, hotels and gyms are used hard from morning to evening. 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 is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Keeping Brentham Garden Suburb washrooms open while we work

A good number of hotels sit less than 2 miles from Brentham Garden Suburb. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Three care or nursing homes sit less than 2 miles from Brentham Garden Suburb. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Each room is kept out of use only as long as the sealant needs.

Toilets at places like Westway Shopping Park, 1.7 miles north-west of Brentham Garden Suburb, are cleaned constantly, so silicone needs to be sound and smooth. Office toilets at parks like Manhattan Business Park (0.5 miles north-east of Brentham Garden Suburb) take steady weekday use, and mouldy silicone soon shows. Halls of residence and teaching buildings at universities such as University of West London (1 mile south of Brentham Garden Suburb) are easiest to reseal during vacations.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Any access equipment needed
  • Working within restricted access windows
  • Which sealant the job calls for
  • Backing rod, priming and other preparation

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • When you need the work done
  • The asbestos register, for older buildings
  • Anything awkward about access or site hours
  • The postcode of the building

For a fixed quote, give us a call on 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. Our quote form is another easy route.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Planning a London job such as one in Brentham Garden Suburb starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Your questions answered

Can work at a site such as University of West London fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll 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.

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for

How long before the toilets can reopen?

Cure times vary by product and temperature. You will get a reopening time for each area, and signs stay up until then.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Do you cover Brentham Garden Suburb?

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Work for main contractors and building owners

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Brentham Garden Suburb. Several sites can go on one quote, which keeps the paperwork simple.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

When something else is needed

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • A dripping waste or valve behind a panel
  • Condensation from failed extract fans
  • Hollow tiles or loose panels behind the joint

Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we will tell you honestly.

Joints and surfaces we work on

  • Accessible toilets and changing rooms
  • Kitchens and tea points
  • Vanity units and basins
  • IPS panels and cubicles
  • Showers, trays and wet room floors
  • Urinals and WCs

What the job involves on each surface

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. Anti-mould sanitary silicone is the standard choice.

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.
