About our washroom sealing in Rushenden

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. We work on vanity units and basins, showers, trays and wet room floors and kitchens and tea points, and the usual reasons a site gets in touch are open joints at the base of cubicle panels and black mould inside silicone joints that cleaning can’t shift. Looking for mastic applicators who cover Rushenden? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Halls and community buildings near places like Rushenden are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, give us a call on 01277 525 020 or use the quote form and we’ll arrange a return visit.

Signs you need washroom sealing in Rushenden

Sometimes the sealant fails because something behind it is moving or wet: loose fixings, a dripping trap or damp in the wall. We check for that first and say if it needs a plumber or another trade.

These are often picked up first by site or facilities staff:

  • Sealant lifting along a tray edge
  • Failed sealant behind washroom basins
  • Stained sealant around pans and urinals
  • Failed joints along IPS and cubicle panels

Church halls and community buildings, such as those at Parish Church of the Holy Trinity, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

What your quote should include

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will CSCS-carded applicators be on site?
  • How long is the guarantee, and what does it include?
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • Any access equipment needed
  • Which sealant the job calls for
  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Sending details for a quote

To price the job accurately, we need to understand the site. Useful things to include:

  • Your programme or deadline
  • Clear photographs of the problem areas
  • The type of building and who uses it
  • The site address and postcode

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Why deal with it now?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Halls, stores and units around places like Rushenden may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Why appoint us

  • CHAS accredited contractor
  • RAL and finish matching where the product range allows
  • Colour options checked against the specified product
  • Work to your specification and the manufacturer’s guidance

Site staff or a sealant specialist?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

For managing agents and facilities managers

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Sanitary sealant for Rushenden buildings

Rushenden is within about 1 mile of the coast, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Washrooms used guest after guest wear their sanitary silicone faster, which is why off-season resealing makes sense. At about 36 miles from central London, Rushenden is within reach of the capital. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.

At a school such as Queenborough School and Nursery, changing rooms and kitchens need cleanable joints as much as the toilets. Toilets at colleges like Sheppey College (to the north of Rushenden) take heavy use from students and staff alike.

Rushenden is about 2 miles south-west of Sheerness, in Kent. Any commercial site in Rushenden is covered, whether it’s a single job or part of a planned programme. Our Kent coverage takes in 931 places, large and small. Sites around London have their own page, roughly 36 miles from Rushenden.

If your building is just outside Rushenden, we cover Queenborough (1 mile north-east), Halfway Houses (2 miles north-east), Sheerness (2 miles north-east), Blue Town (2 miles north) and Grain (3 miles north). Bigger towns within reach include Maidstone (14 miles south-west), Sittingbourne (5 miles south), Whitstable (13 miles east), Faversham (9 miles south-east), Minster (3 miles east) and Davington (9 miles south-east).

Questions we’re asked in Rushenden

Could you schedule work at a campus like Sheppey College for the vacation?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Is Rushenden 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. Good photographs up front let us bring everything on the first visit.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How long does a job like this take?

It depends on the scope, but the work usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. For bigger or phased jobs, we will set out a timescale with the quote.

Will all the toilets be closed at once?

We phase it so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.
