About washroom sealing in Kent

Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. An open joint there lets water track under flooring or behind wall panels so they get particular attention. The enquiries we see most involve resealing that didn’t last because the old bead stayed and shower tray joints that have opened up, across urinals and WCs, accessible toilets and changing rooms and IPS panels and cubicles.

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area.

We inspect each washroom and record the joints to be resealed.
You get a fixed quote with the phasing plan.
Old sealant is removed completely and the faces cleaned.
Each joint is cleaned and left dry.
New anti-mould sealant goes in and is tooled neat.
Each area is handed back when ready.

Washrooms and wet areas in Kent

Across Kent, hospitality kitchens and toilets need sealed joints that clean easily. Sanitary and hygienic sealants go in, food-safe where food could come into contact with it.

We work across Greater London and the South East counties, so jobs in Kent are planned with access, loading and parking in mind. On the coastal side of Kent, sea-facing elevations normally show failed joints first, so they’re worth inspecting more often.

Maidstone: At a hospital like The Somerfield Hospital, 1.1 miles to the north-west of Maidstone, patient and staff washrooms are best done in short phases agreed with the ward. For centre management at a site such as The Mall Maidstone, 0.5 miles to the north of Maidstone, washroom work is planned around footfall.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

The size and state of each joint
How much existing material needs removing
Any access equipment needed
Whether the work must be split into stages

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Sending details for a quote

We can often quote from photographs and a few details. It helps to include:

Asbestos survey details if the building is older
When you need the work done
The type of building and who uses it
Approximate linear metres or a joint schedule

Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to call the office on 01277 525 020 or send details through our quote form.

What happens if it’s left?

A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now.

What your quote should include

How long is the guarantee, and what does it include?
How they handle RAMS and site documents
Their public liability cover
Health and safety accreditation such as CHAS

Work for main contractors and building owners

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Looking after the joints

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

Don’t leave an open joint at a basin or tray
Squeegee showers and trays after busy periods
Brief cleaning staff to treat joints gently
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 and give mould a start.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

When something else is needed

Before quoting, we check that sealant is the right answer. It won’t put right:

Mould caused by poor ventilation, which will return until the extract is fixed
Panel boards already damaged by water
Fittings that move too much to hold a bead

FAQs: Kent

Do you guarantee washroom sealing?

Our workmanship has a 12-month guarantee backed by public liability insurance.

Can you handle several sites?

Yes. Several buildings can share a single quote, with one point of contact.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives in most cases. We use neutral-cure versions on stone, some metals and near mirrors.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

How much does the work cost?

Every job gets its own fixed quote. For yours, phone 01277 525 020 or email the details over with a description of the work.

Are you insured?

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

How long before the toilets can reopen?

Each sealant has a cure time before it should get wet. We plan the phasing around that so there are always rooms open.
