Advice
About our washroom sealing in Trench Green
Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we will plan around them. Most enquiries involve open joints along basins and vanity units and complaints from staff, guests or users about tired washrooms, across IPS panels and cubicles, showers, trays and wet room floors and vanity units and basins. Searching for sealant specialists in Trench Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Halls and community buildings near places like Trench Green are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Distance, for remote addresses
- Which sealant the job calls for
- Removal of failed or old sealant
- How much there is to seal
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Before you send an enquiry
However big the job, these details speed things up:
- Rough lengths or quantities, or drawings if you have them
- Any dates the work must fit around
- Specification clauses that apply
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Washroom sealing around Trench Green: what changes locally
Trench Green is about 40 miles from central London, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time.
On a healthcare site such as Battle Hospital, which lies south of Trench Green, washroom work starts with the infection-control team’s sign-off. Toilets at places like Reading Retail Park (2.3 miles south of Trench Green) are cleaned constantly, so silicone needs to be sound and smooth.

Trench Green: questions and answers
Do you take on work at healthcare sites like Battle Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is Trench Green too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Is it possible to just clean mouldy silicone?
Not for long. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacement is the lasting fix.
What guarantee comes with washroom resealing?
There is a 12-month guarantee on our workmanship backed by public liability insurance.
How many days will you need on site?
That varies with the scale of the job, though a typical visit usually takes between a morning and a week or so, set by the number of rooms and the phasing you need. For bigger or phased jobs, we’ll set out a timescale with the quote.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- 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 you are not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
What we seal
- Accessible toilets and changing rooms
- Urinals and WCs
- Showers, trays and wet room floors
- Kitchens and tea points
- Vanity units and basins
- IPS panels and cubicles
Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Don’t leave an open joint at a basin or tray
- Add sealant joints to planned maintenance checks
- Don’t leave trays and floors sitting wet
- Tell us about infection-control or permit rules before we quote
Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.
In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
When to call us in Trench Green
Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We check for that first and tell you if another trade is needed.
Look out for the following:
- Shower tray joints that have opened up
- Stained sealant around pans and urinals
- Stained or open joints at kitchen sinks and worktops
- Washrooms that look worn because of the sealant
If you manage an office at a site such as Oxford Road Business Park, 1.9 miles south of Trench Green, the washrooms and tea points can be done a floor at a time.
What your quote should include
- What level of public liability insurance do they hold?
- How long is the guarantee, and what does it include?
- Which product they’ll use, and why it suits the joint
- Are they CHAS accredited or on Constructionline?
