Washroom sealing for Coxford sites

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

When something else is needed

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Vanity carcasses that have swollen
  • Water from plumbing, not from a joint
  • Condensation from failed extract fans

If in doubt, ring 01277 525 020 or email the details over and we’ll say what we think.

What we seal

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

Washroom sealing in Coxford

Accessible WCs, showers and changing areas have their own pinch points: shower trays, wet-room floor edges, basins and floor-to-wall junctions. An open joint there lets water track under flooring or behind wall panels so they get particular attention. We work on accessible toilets and changing rooms, IPS panels and cubicles and urinals and WCs, and what we are called in for most is shower tray joints that have opened up and users noticing mouldy joints. Looking for mastic applicators who cover Coxford? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Around Coxford, washroom work normally comes one building at a time. A list and photographs let us quote and plan so it’s done in one visit where possible.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Quoting for work in Coxford

The price varies from site to site. It mainly depends on:

  • Specialist products, such as fire-rated or hygienic sealants
  • Site requirements such as inductions and permits
  • Access and working height
  • How much existing material needs removing

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

What we need to price the job

We can often quote from photographs and a few details. Please tell us:

  • How the joints are reached, and at what height
  • Rough lengths or quantities, or drawings if you have them
  • The type of building and who uses it
  • The site address and postcode

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or send details through our quote form with what you know.

Washroom sealing around Coxford: points for this area

With the shore within about 2 miles, Coxford counts as a coastal location, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Heavy seasonal use is hard on shower and basin sealant, and the quieter months are the natural time to reseal. Two care or nursing homes sit less than 2 miles from Coxford. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Each room is kept out of use only as long as the sealant needs.

Staff changing rooms and patient toilets at places like Southampton General Hospital (less than half a mile east of Coxford) need cleanable, sound silicone. Church halls and community buildings, such as those at St Jude's Church, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Coxford is about 2 miles north-west of Southampton, in Southampton. Businesses, contractors and managing agents in Coxford can call on us for washrooms and wet areas. 30 places across Southampton fall within our area, including Coxford.

When to call us in Coxford

Warmth, moisture and soap residue are exactly what mould needs, and silicone joints hold onto all three. Even anti-mould grades can be colonised over time where extraction is poor.

If one of these sounds familiar, it’s time for a closer look:

  • Shower tray joints that have opened up
  • Failed joints along IPS and cubicle panels
  • Complaints from staff, guests or users about tired washrooms
  • Black mould inside silicone joints that cleaning can’t shift

Toilets at colleges like Richard Taunton Sixth Form College (to the south-east of Coxford) take heavy use from students and staff alike.

What to look for in a quote

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their pre-qualification and accreditations
  • Is the sealant right for the movement and the substrate?
  • How they handle RAMS and site documents

Choosing a commercial sealant contractor

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Common questions from Coxford clients

Is Coxford too far out for you?

Not at all. Coxford is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Must a hotel around Coxford close while you work?

Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we will plan around them.

When is resealing likely to be due?

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

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.

Is it possible to just clean mouldy silicone?

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

Do you phase washroom resealing?

The work is phased so there are always facilities open. We work through the building a room or section at a time. Tell us your site hours and access windows and we will plan around them.

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

We strip every bit of the failed bead and wipe away the residue first. It’s the difference between a joint that lasts and one that peels.

Different surfaces, different methods

Healthcare and care settings

We phase washroom sealing so care areas are never left without facilities. Tell us what records you need and we will confirm with the quote.

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors, so their perimeter joints get close attention.

From enquiry to sign-off

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. If neighbouring businesses or buildings around Coxford need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  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.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Tell us your opening times and when work is allowed
  • Point out parking and an unloading spot
