Keeping Dengie washrooms open while we work
With the shore within about 3 miles, Dengie counts as a coastal location, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Bathrooms turned round daily in the busy months need sound, cleanable joints, so resealing in the quieter months keeps rooms ready. Central London is about 43 miles from Dengie, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time.
Halls linked to places like Church of St James host groups all week, which is hard on kitchen and toilet sealant.

Smaller places such as Dengie still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

On site: what to expect
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking between a morning and a week or so, set by the number of rooms and the phasing you need. Smaller jobs around Dengie can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- We survey each room, count the joints and note anything behind them that needs another trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- We strip out the old bead and clean off the residue left behind.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- Rooms reopen after the product’s cure time, and we move to the next.
Preparing the site
- For older buildings, check the asbestos register before work
- Let us know about inductions and permits
- Let building users know which areas are affected

Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Do you need washroom sealing in Dengie?
Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.
Common reasons buildings call us in:
- Split or peeling sealant at shower trays
- Mould spotting along silicone joints
- A new bead over an old one coming away
- Washrooms that look worn because of the sealant
At a university such as University of Essex, 2.8 miles north-west of Dengie, summer is the usual window for resealing residence bathrooms.
Questions to ask before you book
- How they handle RAMS and site documents
- Who will actually carry out the work
- Their pre-qualification and accreditations
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Dengie: questions and answers
Is a smaller place like Dengie outside your area?
No. Places such as Dengie are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Do we have to close all our washrooms in Dengie for resealing?
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 will tell you how long for the product used.
Do you phase washroom resealing?
The work is phased so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we will plan around them.
How soon can a washroom be used after resealing?
The silicone needs time to cure before water reaches it. We plan the phasing around that so there are always rooms open.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Surface by surface
Showers and trays
A tray that rocks or has cracked won’t be fixed by sealant, and we will say so before resealing.
IPS and cubicle panels
A panel that has already swollen won’t be fixed by sealant and we’ll point out any we see.
What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Vanity carcasses that have swollen
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Water escaping beneath the floor rather than through a joint
If you’re not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer before you book.
