How we handle washroom sealing in Cippenham
In healthcare and care settings, sealing is part of keeping surfaces cleanable. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Any records you need are confirmed with the quote. We work on showers, trays and wet room floors, urinals and WCs and kitchens and tea points, and the usual reasons a site gets in touch are stained sealant around pans and urinals and stained or open joints at kitchen sinks and worktops. Searching for sealant specialists in Cippenham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Jobs in a smaller place such as Cippenham are often one building: a school’s toilets, a café kitchen, a surgery’s washrooms. Photos of each area help us plan the visit and bring the right sealant.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or email the details over and we’ll arrange a return visit.

Common problems we fix in Cippenham
Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We look for it before resealing and say if it needs a plumber or another trade.
Most enquiries start with one or more of the following:
- Resealing that didn’t last because the old bead stayed
- Sealant lifting along a tray edge
- Open joints at the base of cubicle panels
- Black mould inside silicone joints that cleaning can’t shift
Halls linked to places like St. Andrew's Shared Church host groups all week, which is hard on kitchen and toilet sealant.

Common questions from Cippenham clients
Is hospital work, at somewhere like Upton Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can work in a care setting near Cippenham go ahead while residents are there?
Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Are you insured?
Yes. We’re fully insured, including public liability cover.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Is it possible to just clean mouldy silicone?
Typically not. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.
Keeping Cippenham washrooms open while we work
Cippenham lies roughly 23 miles out from central London. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open. A 2-mile radius around Cippenham takes in plenty of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest.
Toilets at places like Westgate Retail Park (under half a mile east of Cippenham) are cleaned constantly, which is hard on silicone. Healthcare washrooms on sites such as Upton Hospital, 2.1 miles to the east of Cippenham, are resealed area by area, under the site’s own infection-control rules.
Cippenham is about 1 mile west of Slough, in Slough. If you’re looking for washroom sealing in Cippenham, we can help. We work across 11 places in Slough, from busy centres to rural villages. For work in that direction, see our Reading page, about 15 miles away.
Commercial sites across SL1 and SL2 are covered. Buildings on Bath Road, Earls Lane and Eagle Road are within our area for washrooms and wet areas. We also cover Huntercombe (1 mile north-west), Lake End (1 mile west), Dorney (1 mile south-west), Slough (1 mile east) and Burnham (1 mile north-west). Nearby towns on our patch include Langley (4 miles east), Wexham Court (3 miles east), Poyle (6 miles south-east) and Colnbrook (5 miles south-east).
Near you in Cippenham
In Cippenham, that means premises near The Westgate School, Westgate School and Haymill Valley and the streets around them. For rail, the closest station is Burnham station, about 0.6 miles north-west of the centre. A little further out are Windsor Castle (2.7 miles south-east) and The History On Wheels Museum (1.1 miles south-east). The countryside around Cippenham includes Bray Pit and Taplow Lake.
Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. 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. Work in places the size of Cippenham is planned as a single visit where we can. Clear photos and measurements help us bring the right products.
- 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.
- The failed silicone is stripped and every face scraped clean of residue.
- 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
- Arrange parking or a loading space
- Clear stock, furniture or equipment away from the joints
- Tell us what induction or permit system the site runs

What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- A room that stays damp because ventilation isn’t working
- Failed tanking beneath a wet-room floor or behind tiles
- Fittings that move too much to hold a bead
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
Surfaces we seal
- Showers, trays and wet room floors
- Urinals and WCs
- Kitchens and tea points
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Vanity units and basins
Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Why deal with it now?
Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. For buildings in places like Cippenham, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
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 when you are ready.
