What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Hollow tiles or loose panels behind the joint
  • Swollen or delaminated boards behind panels or vanity tops

If you are not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Washroom sealing in South Moreton

You can’t shut every toilet in an office, school or hotel at once. 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’ll plan around them. If you are dealing with failed sealant in a tea point or staff kitchen and complaints from staff, guests or users about tired washrooms, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in South Moreton it comes down to the same thing: the right product in a properly prepared joint.

In and around smaller places like South Moreton, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould usually can’t be cleaned, so it is cut out and replaced.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Questions about South Moreton

Do we have to close all our washrooms in South Moreton for resealing?

Typically 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.

Is South Moreton off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Can you clean the mould off instead of resealing?

Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.

Which silicone is right for commercial washrooms?

Each area gets the grade that suits it. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

What’s the quickest route to a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Why act early in South Moreton

When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. Halls, stores and units around places like South Moreton may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Why us?

  • Colour agreed before work starts
  • A range of standard colours, depending on the product
  • Failed material removed, not covered up
  • Work carried out by CSCS-carded applicators

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. South Moreton can form part of a wider programme.

Sanitary sealant for South Moreton buildings

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Keep a record of which washrooms need attention
  • Report split joints at trays and basins early
  • Clean sealant with gentle products and a soft cloth
  • Mention any site permits or estates rules at quote stage

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life over time.

Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.

How the quote is worked out

We price every job individually. The main factors are:

  • How much existing material needs removing
  • Any access equipment needed
  • Site requirements such as inductions and permits
  • How much there is to seal

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What to include in your enquiry

Good information means a firmer quote. Helpful details to send:

  • Drawings or a marked-up plan, if available
  • Whether an asbestos survey exists
  • Your programme or deadline
  • Specification clauses that apply

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email the details over.

On site: what to expect

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, with the work itself typically taking between a morning and a week or so, set by the number of rooms and the phasing you need. If others near South Moreton need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Getting the site ready

  • Flag any permit to work we will need
  • Confirm the product named in the specification
  • Share your working hours and any access restrictions

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
