Need washroom sealing in Hammerwood?

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Do you need washroom sealing in Hammerwood?

Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Even anti-mould grades can be colonised over time where extraction is poor.

Look out for the following:

  • Panel joints letting water behind
  • Failed sealant in a tea point or staff kitchen
  • Sealant stained black around basins and showers
  • Stained sealant around pans and urinals

For buildings on a site such as Riverview Business Park, 2.8 miles south of Hammerwood, washrooms and tea points can be resealed in phases through the working week.

Before you book anyone

  • Who will actually carry out the work
  • Will RAMS and insurance details be available?
  • Can the work be phased to keep areas open?
  • Which product they’ll use, and why it suits the joint

Questions to ask before you appoint anyone

About our washroom sealing in Hammerwood

Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. We work on accessible toilets and changing rooms, urinals and WCs and vanity units and basins, and what we are called in for most is failed sealant in a tea point or staff kitchen and sealant stained black around basins and showers. Facilities teams, main contractors and managing agents in Hammerwood tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Farm shops, cafés and venues in converted rural buildings around places like Hammerwood have busy toilets and kitchens. We plan the work around bookings and opening times.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Our process

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. For work around Hammerwood, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Joints are cleaned, degreased and dried before sealing.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Each room is handed back once the sealant has had its cure time.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Make sure the joints can be reached
  • Warn occupants and staff about the work

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

What the job involves on each surface

IPS and cubicle panels

Swollen or delaminated boards need replacing and we’ll point out any we see.

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant and we choose a neutral-cure grade for them.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • A dripping waste or valve behind a panel
  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Water escaping beneath the floor rather than through a joint

If in doubt, call the office on 01277 525 020 or email the details over and we’ll say what we think before you book.

What we seal

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

Sanitary sealant for Hammerwood buildings

Hammerwood lies roughly 26 miles out from central London, within the office belt around the capital. Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available.

At a school such as Sackville School, changing rooms and kitchens need cleanable joints as much as the toilets. Where you are responsible for a hall attached to a building such as Church of St Stephen, its kitchen and toilets need sealant that stays cleanable.

Hammerwood is about 3 miles east of East Grinstead, in East Sussex. Across the RH19 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across East Sussex, 308 places are covered, Hammerwood among them. Our Brighton page has more on work in that area.

Work on washrooms and wet areas is covered throughout RH19, whatever the building. If your building is just outside Hammerwood, we cover Ashurst Wood (2 miles south-west), Cowden (2 miles east), Dormansland (2 miles north-west), Dormans Park (2 miles west) and East Grinstead (3 miles west).

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Joint width, depth and condition
  • The product specified
  • Whether the work must be split into stages
  • Site requirements such as inductions and permits

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Sending details for a quote

Whether it’s one area or a whole building, these details speed things up:

  • The postcode of the building
  • Specification clauses that apply
  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Questions we are asked in Hammerwood

Can you take on a job at a hospital such as Queen Victoria Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Must every washroom in our Hammerwood building shut while you work?

Normally only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

What will the job cost?

There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.

Is it OK to put new silicone on top of the old?

The whole of the old bead is removed and the surfaces cleaned before resealing. That’s what makes the new joint last.
