About our washroom sealing in Hassell Street

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. If you are dealing with split or peeling sealant at shower trays and a new bead over an old one coming away, we can put it right, whatever the surface. Whoever orders the work in Hassell Street, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Farm shops, cafés and venues in converted rural buildings around places like Hassell Street have busy toilets and kitchens. Tell us your opening times and quiet periods and we will plan around them.

What our 12-month guarantee covers is the way we did the job: 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 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. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

What the job involves on each surface

Healthcare and care settings

We phase washroom sealing so care areas are never left without facilities. Records you need can be confirmed with the quote.

Urinals and WC pans

Urinal backs, troughs and slab joints are resealed with sanitary silicone after the old bead and residue are removed.

Your questions answered

Can you work on a hospital site such as William Harvey Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is Hassell Street too small for you to travel to?

Not at all. Hassell Street is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

When can showers be used after new sealant?

That varies with the sealant and the room temperature. You’ll get a reopening time for each area before we leave it.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Do you need washroom sealing in Hassell Street?

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They don’t stand up to constant water and they discolour and fail early.

Any of the following is a good reason to get the joints checked over:

  • Failed sealant behind washroom basins
  • Sealant lifting along a tray edge
  • Discoloured joints around urinals and WC pans
  • A new bead over an old one coming away

For a school such as Wye School, washroom and kitchen sealant can be renewed around term dates.

Before you book anyone

  • Do they follow the manufacturer’s priming guidance?
  • Their pre-qualification and accreditations
  • Whether their applicators hold CSCS cards
  • Can the work be phased to keep areas open?

How to choose a sealant contractor

Owners, agents and contractors

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

What sealant work can’t fix

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Swollen or delaminated boards behind panels or vanity tops
  • Failed tanking beneath a wet-room floor or behind tiles
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think before you book.
