Washroom sealing for Merle Common sites

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

Should maintenance staff do it?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Redoing a failed joint usually costs more than getting it right at the outset, 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.

About our washroom sealing in Merle Common

Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we will plan around them. We work on kitchens and tea points, urinals and WCs and accessible toilets and changing rooms, and the usual reasons a site gets in touch are a new bead over an old one coming away and failed sealant behind washroom basins. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Merle Common, that means joint design, primers and backing rod as standard.

Community buildings around smaller places like Merle Common have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes half a day to a day per washroom, depending on the number of fittings, and we clear our waste as we work. Smaller jobs around Merle Common can be grouped with others nearby. You will have a fixed quote before work starts.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

What we need from you

When something else is needed

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Condensation from failed extract fans
  • Loose panels, vanity units or tiles, which need fixing first
  • Swollen or delaminated boards behind panels or vanity tops

If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Where we work in Merle Common

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

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Inspect washroom sealant regularly
  • Leave signs up until the cure time is over
  • Keep extract fans working and vents clear
  • Act on the first split you see at a shower tray

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.

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

What affects the price in Merle Common

To price the job, we consider:

  • Access and working height
  • The total length or number of joints
  • Induction, permit and paperwork requirements
  • Travel to remote or island sites

A quote for washrooms and wet areas depends on how many there are, their condition and the access. Ask us for a fixed quote.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Send us:

  • The site address and postcode
  • Specification clauses that apply
  • Asbestos survey details if the building is older
  • Anything awkward about access or site hours

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or send details through our quote form.

For managing agents and facilities managers

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Merle Common can sit alongside others in a wider programme.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

FAQs: Merle Common

Is Merle Common too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Will the toilets in our Merle Common building be out of use?

Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

Can you clean the mould off instead of resealing?

Usually not. The mould is inside the silicone so cleaning only lightens it for a while. Replacing the bead is the lasting answer.

What about RAMS and site documents?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

Do you phase washroom resealing?

We phase it so there are always facilities open. We work through the building a room or section at a time around your site hours and access windows.

Do you have public liability insurance?

Yes. Mastic Doctor is fully insured, public liability included.
