Washroom sealing in Seaford

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes a morning or so for a small washroom, longer where showers and changing rooms are included. Most work in Seaford is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.

  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. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Point out any areas we must not close
  • Send any specification or drawings in advance

About our washroom sealing in Seaford

In a busy washroom, the sealant normally gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. Most enquiries involve black mould inside silicone joints that cleaning can’t shift and resealing that didn’t last because the old bead stayed, on IPS panels and cubicles, accessible toilets and changing rooms and kitchens and tea points. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Seaford is the same: the right product in a properly prepared joint.

For hospitality businesses in towns like Seaford, sealed joints in kitchens and toilets help keep surfaces easy to clean. Cleanable surfaces are something environmental health officers look at, and sealed joints help.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Hollow tiles or loose panels behind the joint
  • Swollen or delaminated boards behind panels or vanity tops
  • Leaks through tanking or membranes below the finishes

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

What we seal

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

Questions about Seaford

Will you plan work around the academic year at somewhere like University of Brighton?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you work in a care home near Seaford with residents in?

Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we will work to them.

Do you guarantee washroom sealing?

Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

Will cleaning remove black mould from sealant?

Not for long. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacement is the lasting fix.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Common problems we fix in Seaford

Mop buckets, trolleys and knocks from users damage joints near the floor at skirting lines, urinal bases and around pans.

Things that typically lead to an enquiry:

  • A new bead over an old one coming away
  • Gaps where vanity tops meet the wall
  • Discoloured joints around urinals and WC pans
  • Sealant stained black around basins and showers

For a hotel such as Wellington Hotel (0.5 miles south-west of Seaford), resealing en suites a few rooms at a time keeps the rest available.

What to look for in a quote

  • Which product they’ll use, and why it suits the joint
  • What level of public liability insurance do they hold?
  • Their plan for phasing and protecting the area
  • Will failed sealant be removed rather than covered?

Choosing a commercial sealant contractor

After the work

A few simple habits keep the new joints working:

  • Photograph and log failed joints across the estate
  • Clear standing water from shower floors where possible
  • Keep extract fans working and vents clear
  • Brief cleaning staff to treat joints gently

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface over time.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

How the quote is worked out

Before we quote, we look at:

  • The size and state of each joint
  • Site requirements such as inductions and permits
  • Specialist products, such as fire-rated or hygienic sealants
  • Whether old sealant has to be cut out first

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

What to include in your enquiry

However big the job, the same details help:

  • Specification clauses that apply
  • The site address and postcode
  • What the building is and how it’s used
  • The asbestos register, for older buildings

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email drawings and photos with what you know.

When to bring in a specialist

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 where general trades tend to cut corners.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
