What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Water from plumbing, not from a joint
- Failed tanking beneath a wet-room floor or behind tiles
- Hollow tiles or loose panels behind the joint
If in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think.
Surfaces we seal
- Accessible toilets and changing rooms
- Vanity units and basins
- Kitchens and tea points
- IPS panels and cubicles
- Showers, trays and wet room floors
- Urinals and WCs
About our washroom sealing in Halstead
Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Every resealed washroom carries our 12-month guarantee. We work on vanity units and basins, accessible toilets and changing rooms and IPS panels and cubicles, and the failures we are asked to look at most are open joints at the base of cubicle panels and sealant lifting along a tray edge. Whoever orders the work in Halstead, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Community buildings around smaller places like Halstead have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

What else we do in Halstead
When to bring in a specialist
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
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.
Common questions from Halstead clients
Will all the washrooms in our Halstead building be closed at once?
Not all at once. We take one block of facilities at a time. We’ll tell you the curing time for the product before we start.
Can you take on a job at a hospital such as Chelsfield Park Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
When can showers be used after new sealant?
That varies with the sealant and the room temperature. Each room gets its own reopening time from us, and signs stay up until then.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
What sets the cost
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- How accessible the joints are
- Whether old sealant has to be cut out first
- Travel to remote or island sites
- The total length or number of joints
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
However big the job, these details speed things up:
- The site address and postcode
- A wide shot and a close-up of the area
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
To get a fixed quote, ring 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. You can also send details through our quote form.
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Keep washrooms out of use until we say the sealant has cured
- Act on the first split you see at a shower tray
- Clear standing water from shower floors where possible
- Mention any site permits or estates rules at quote stage
Include sealant joints in your planned maintenance checks. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and photograph anything new.
Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.
Owners, agents and contractors
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a morning or so for a small washroom, longer where showers and changing rooms are included, and we clear our waste as we work. For work around Halstead, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We inspect each washroom and record the joints to be resealed.
- The fixed quote sets out the rooms, the products and the phasing.
- Old sealant is removed completely and the faces cleaned.
- Each joint is cleaned and left dry.
- A sanitary silicone bead is laid and given a smooth tooled finish.
- Each area is handed back when ready.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Send your site hours and access windows
- Arrange parking or a loading space

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Advice
Wet areas in Halstead’s workplaces
At about 15 miles from central London, Halstead is within reach of the capital, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available.
For a school such as Halstead Community Primary School, washroom and kitchen sealant can be renewed around term dates. If you manage an office at a site such as North Downs Business Park, which lies south-east of Halstead, the washrooms and tea points can be done a floor at a time. Church halls and community buildings, such as those at St Margaret's Church, have kitchens and toilets used by many groups, and their sanitary sealant works hard.
