Washroom sealing for commercial buildings in Hamsey Green
We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. We work on urinals and WCs, showers, trays and wet room floors and vanity units and basins, and the usual reasons a site gets in touch are a new bead over an old one coming away and shower tray joints that have opened up. Searching for sealant specialists in Hamsey Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

When it isn’t the sealant
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Panel boards already damaged by water
- A dripping waste or valve behind a panel
- A room that stays damp because ventilation isn’t working
If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think before you book.

Questions about Hamsey Green
Could you schedule work at a campus like John Ruskin College for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you take on jobs in Hamsey Green where loading and access are tightly controlled?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
How much does the work cost?
There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.
Will all the toilets be closed at once?
The work is phased so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.
Which silicone is right for commercial washrooms?
Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.
Is it OK to put new silicone on top of the old?
We always remove it. Fresh silicone can’t key to an old bead, so sealing over it soon peels.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Wet areas in Hamsey Green’s workplaces
Hamsey Green has several hotels close by, all within 2 miles. 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. Two care or nursing homes sit less than 2 miles from Hamsey Green. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. We plan the work with the manager so residents are disturbed as little as possible.
Church halls and community buildings, such as those at St Antony, have kitchens and toilets used by many groups, and their sanitary sealant works hard. Toilets at places like Church Walk Shopping Centre (to the south of Hamsey Green) are cleaned constantly, which is hard on silicone.

Signs you need washroom sealing in Hamsey Green
We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting and they discolour and fail early.
Look out for the following:
- Black mould inside silicone joints that cleaning can’t shift
- Resealing that didn’t last because the old bead stayed
- Open joints at the base of cubicle panels
- Kitchen worktop joints that can’t be kept clean
On a healthcare site such as Purley War Memorial Hospital, 2.7 miles north-west of Hamsey Green, washroom work starts with the infection-control team’s sign-off.
What to look for in a quote
- How they’ll work around occupants
- What level of public liability insurance do they hold?
- How joint depth will be controlled
- How the joint faces will be prepared and primed
When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Quoting for work in Hamsey Green
These are the things that shape the price:
- The size and state of each joint
- Access and working height
- The product specified
- Location, for remote and island sites
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.
Before you send an enquiry
We can often quote from photographs and a few details. Please tell us:
- Anything awkward about access or site hours
- Whether an asbestos survey exists
- Where the site is, with the postcode
- Photos of the joints, close up and from further back
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, ring 01277 525 020 or email a schedule or drawings.

What else we do in Hamsey Green
For managing agents and facilities managers
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before the next one starts. All of Greater London is in the ULEZ, and kerbside space in Hamsey Green can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- 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.
- The right sanitary or food-safe sealant is applied.
- We give you a reopening time for every room.
Before we start on site
- Agree which areas must stay open
- Tell us your opening times and when work is allowed
- Warn occupants and staff about the work
