Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Eton need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- 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.

Advice
Washroom sealing for commercial buildings in Eton
Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Our workmanship is guaranteed for 12 months. We work on kitchens and tea points, vanity units and basins and accessible toilets and changing rooms, and the failures we are asked to look at most are mould spotting along silicone joints and failed joints along IPS and cubicle panels. A specialist sealant contractor works differently from a general builder: in Eton, that means joint design, primers and backing rod as standard.
Community buildings around smaller places like Eton have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions we are asked in Eton
Could you schedule work at a campus like Windsor College for the vacation?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can you take on a job at a hospital such as Upton 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.
Do you do washroom sealing in healthcare settings?
We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How do we ask for a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Make sure washroom ventilation is running
- Brief cleaning staff to treat joints gently
- Note failing joints building by building
- Include joints in routine washroom inspections
Keep extract fans working and vents clear. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.
Mouldy sealant only gets harder to ignore and users notice. Dealing with it while it’s just the sealant keeps it simple.
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Commercial washrooms in Eton
Central London is about 22 miles from Eton. Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available. A 2-mile radius around Eton takes in a good number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits.
For a store at a site such as Slough Retail Park (1.5 miles north of Eton), the staff room and customer toilets can be resealed in quiet periods. Church halls and community buildings, such as those at Church of Saint John the Evangelist, have kitchens and toilets used by many groups, and their sanitary sealant works hard. Clinical washrooms at sites like Upton Hospital, 1.1 miles to the north-east of Eton, are scheduled with the ward so the room is out of use for as little time as possible.
Eton is about 1 mile north-east of Windsor, in Windsor and Maidenhead. We cover Eton, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Windsor and Maidenhead, 60 places are covered, Eton among them. Sites around Reading have their own page, about 16 miles away.

Honest limits
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Water from plumbing, not from a joint
- Condensation from failed extract fans
- Swollen or delaminated boards behind panels or vanity tops
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we will tell you honestly.

What affects the price in Eton
A fixed quote reflects the actual work. It takes account of:
- Induction, permit and paperwork requirements
- How much existing material needs removing
- How accessible the joints are
- The size and state of each joint
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
- Any specification or named product
- What the building is and how it’s used
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
