About our washroom sealing in Purfleet-on-Thames
Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. We work on urinals and WCs, accessible toilets and changing rooms and kitchens and tea points, and the usual reasons a site gets in touch are sealant lifting along a tray edge and washrooms that look worn because of the sealant. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Purfleet-on-Thames, that means joint design, primers and backing rod as standard.
In a smaller place such as Purfleet-on-Thames, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.
A 12-month guarantee applies to all our work in Thurrock. Should something we installed fail, call 01277 525 020 or email a schedule or drawings and we will come back to it.

Washroom sealing in Purfleet-on-Thames: the local picture
Purfleet-on-Thames is about 14 miles from central London, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open. Purfleet-on-Thames has several hotels close by, all within 2 miles. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. The work can go floor by floor, agreed with housekeeping.
In a centre such as Lakeside Retail Park, which lies east of Purfleet-on-Thames, public washrooms are resealed a block of facilities at a time. For an occupier at a site such as Queen Elizabeth Distribution Park, which lies east of Purfleet-on-Thames, the canteen and welfare facilities need cleanable joints as much as any office.

After the work
Once the work is signed off, these steps help:
- Inspect washroom sealant regularly
- Share your site rules when you send details
- Leave signs up until the cure time is over
- Act on the first split you see at a shower tray
Ask your cleaning team to use gentle products and soft cloths on sealant. Strong acids, solvents and scourers wear the surface and give mould a start.
A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.
What happens if it’s left?
A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. Small buildings around Purfleet-on-Thames suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Surface by surface
Changing rooms and gyms
We phase work so not every changing area is closed at once. Phasing follows your site hours and access windows.
IPS and cubicle panels
Panel systems meet walls, floors and vanity tops at sealed joints. They stop water reaching the panel boards.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Mould caused by poor ventilation, which will return until the extract is fixed
- Swollen or delaminated boards behind panels or vanity tops
- Water escaping beneath the floor rather than through a joint
If in doubt, speak to us on 01277 525 020 or email us and we’ll say what we think.
Joints and surfaces we work on
- Kitchens and tea points
- Vanity units and basins
- IPS panels and cubicles
- Showers, trays and wet room floors
- Urinals and WCs
- Accessible toilets and changing rooms
Your questions answered
Do you take on work at healthcare sites like Little Brook Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will our hotel in Purfleet-on-Thames need to close for the work?
In most cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we will plan around them.
Do you cover Purfleet-on-Thames?
Yes. We take on work across Purfleet-on-Thames, and the same phone number covers every area.
Do you offer coloured sealant?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we will 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. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
