Wellhouse: questions and answers
Would you work within a site like West Berkshire Community 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.
Will all the washrooms in our Wellhouse building be closed at once?
Usually only some of them, for a short time. We work in phases so other facilities stay open. Each area is handed back once the sealant has cured enough to use.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Is there a guarantee on the work?
Our workmanship has a 12-month guarantee, and we carry public liability insurance.
Do you need to remove the old sealant?
The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Washroom sealing in Wellhouse, done properly
Accessible toilets, shower rooms and changing rooms have joints that work harder than most: 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. If you are dealing with black mould inside silicone joints that cleaning can’t shift and washrooms that look worn because of the sealant, we can help. Looking for mastic applicators who cover Wellhouse? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Halls and community buildings near places like Wellhouse are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Quoting for work in Wellhouse
The price varies from site to site. Expect it to depend on:
- Backing rod, priming and other preparation
- Any access equipment needed
- Location, for remote and island sites
- Induction, permit and paperwork requirements
A quote for washrooms and wet areas depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.
Details that help us quote
Diagnosis starts before we arrive. Tell us:
- Drawings or a marked-up plan, if available
- What the building is and how it’s used
- Anything awkward about access or site hours
- A wide shot and a close-up of the area
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or send photos by email.
When to bring in a specialist
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.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Toilets, showers and kitchens around Wellhouse
At about 50 miles from central London, Wellhouse is within reach of the capital, within the office belt around the capital. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.
For a site such as West Berkshire Community Hospital, 3.4 miles to the south-west of Wellhouse, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. For an occupier at a site such as Red Shute Hill Industrial Estate, which lies west of Wellhouse, the canteen and welfare facilities need cleanable joints as much as any office. Pupil toilets at schools like Hermitage Primary School take heavy daily use, and the holidays give the window to reseal.

Diagnose, treat, sign off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact.

- First, the phasing is agreed so facilities stay open.
- Leaks, loose panels or damp are pointed out first.
- Old sealant is stripped and the faces prepared.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
Getting the site ready

What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- A room that stays damp because ventilation isn’t working
- Water from plumbing, not from a joint
- Panel boards already damaged by water
Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly.
Surfaces we seal
- Urinals and WCs
- Showers, trays and wet room floors
- Accessible toilets and changing rooms
- Kitchens and tea points
- Vanity units and basins
- IPS panels and cubicles
Different surfaces, different methods
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. Anti-mould sanitary silicone is the standard choice.
Kitchens and tea points
Worktop, sink and splashback joints in tea points take water and food. Sealed joints leave no gaps for food and dirt.
Why deal with it now?
When a washroom looks worn, a refit isn’t the only answer. If the finishes are in good order, replacing the sealant may do much of what’s needed while bigger works are planned. Around Wellhouse, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
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.
What you get with us
- Coloured sealants to suit the setting, where available
- 12 months’ guarantee on every job
