Washroom sealing for businesses in Old Windsor
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. If neighbouring businesses or buildings around Old Windsor need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- Every room is surveyed and the failed joints listed.
- You get a fixed quote with the phasing plan.
- The whole of the old bead is removed.
- Joints are degreased and dried.
- New anti-mould sealant goes in and is tooled neat.
- Each area is handed back when ready.
Preparing the site
- For older buildings, check the asbestos register before work
- Confirm the product named in the specification
- Share your working hours and any access restrictions

About our washroom sealing in Old Windsor
Whether it’s a single toilet block in Old Windsor or a programme across several buildings, we work the same way: send details, get a fixed quote, we seal, guaranteed. A few photographs and a count of fittings are enough for a quick quote and a site visit is an option. Site teams most often ask us about split or peeling sealant at shower trays and sealant stained black around basins and showers, on urinals and WCs, IPS panels and cubicles and showers, trays and wet room floors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Old Windsor, that means joint design, primers and backing rod as standard.
In and around places like Old Windsor, hospitality kitchens and toilets see heavy use in busy spells. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Commercial washrooms in Old Windsor
Plenty of hotels sit less than 2 miles from Old Windsor. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. We work a handful of rooms at a time, so the hotel keeps letting the rest. Old Windsor lies roughly 21 miles out from central London. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open.
For a college such as Windsor College, 2 miles to the north-west of Old Windsor, half-term and summer give the windows for washroom work. Halls linked to places like St Luke host groups all week, which is hard on kitchen and toilet sealant. Office toilets at parks like Portland Business Park (to the north of Old Windsor) take steady weekday use, and mouldy silicone soon shows.

Questions about Old Windsor
Is hospital work, at somewhere like Princess Margaret Hospital, something you do?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can you work around term dates at a campus such as Royal Holloway University?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is old silicone taken out first?
We strip every bit of the failed bead and wipe away the residue first. That’s what makes the new joint last.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How long before the toilets can reopen?
That varies with the sealant and the room temperature. Each room gets its own reopening time from us, and signs stay up until then.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Why act early in Old Windsor
A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. In a smaller place such as Old Windsor, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
A quote for washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What sets the cost
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Specialist products, such as fire-rated or hygienic sealants
- Removal of failed or old sealant
- Distance, for remote addresses
- The site’s rules and procedures
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Before you send an enquiry
Good information means a firmer quote. When you get in touch, include:
- Asbestos survey details if the building is older
- The site address and postcode
- The type of building and who uses it
- Clear photos of the problem areas
To get a fixed quote, ring 01277 525 020 or email the details over. Our quote form is another easy route.
Maintenance after handover
After handover, these steps help:
- Leave signs up until the cure time is over
- Add sealant joints to planned maintenance checks
- Squeegee showers and trays after busy periods
- Share your site rules when you send details
Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.
Mould in a joint spreads along the bead and into nearby grout and users notice. Replacing it early keeps the job to a reseal.
How the job changes by surface
Changing rooms and gyms
Changing rooms can be phased so one stays open. Tell us your site hours and access windows and we will plan around them.
IPS and cubicle panels
IPS panels and cubicle systems have joints at the wall, the floor and the worktop. They stop water reaching the panel boards.
