Washroom sealing in Hudnall, done properly
We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. Product and method follow how hard each area is used and cleaned. If you have failed joints along IPS and cubicle panels and mould spotting along silicone joints, we can help, on showers, trays and wet room floors, vanity units and basins and kitchens and tea points alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Hudnall it comes down to the same thing: the right product in a properly prepared joint.

When to call us in Hudnall
A lot of failed washroom sealant was laid over an old bead or a dirty surface. Silicone won’t adhere to a silicone bead, so it soon lets go.
If one of these sounds familiar, it’s time for a closer look:
- Washrooms that look worn because of the sealant
- Gaps where vanity tops meet the wall
- Failed joints along IPS and cubicle panels
- Discoloured joints around urinals and WC pans
Hotels such as The Bridgewater Arms Hotel, 0.8 miles to the north-west of Hudnall, have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.
What to look for in a quote
- Will failed sealant be removed rather than covered?
- How joint depth will be controlled
- Are they CHAS accredited or on Constructionline?
- Their plan for phasing and protecting the area

Honest limits

- Loose panels, vanity units or tiles, which need fixing first
- Swollen or delaminated boards behind panels or vanity tops
- Water from plumbing, not from a joint
If you’re not sure, just call 01277 525 020 or send photos by email and we’ll give you a straight answer.
What we seal
- Vanity units and basins
- Accessible toilets and changing rooms
- Urinals and WCs
- IPS panels and cubicles
- Kitchens and tea points
- Showers, trays and wet room floors
General trades versus a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Questions about Hudnall
Is hospital work, at somewhere like Hemel Hempstead Hospital, something you do?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is Hudnall off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Do you guarantee washroom sealing?
A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Can washrooms stay open while you work?
We phase it so users always have somewhere to go. We work through the building a room or section at a time. Tell us your site hours and access windows and we will plan around them.

Work for main contractors and building owners
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Building owners and managing agents use us on everything from one building to a spread of sites around Hudnall. Several sites can go on one quote, which keeps the paperwork simple.
From enquiry to sign-off
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For work around Hudnall, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We survey each room, count the joints and note anything behind them that needs another trade.
- We agree which rooms close and when, so users always have somewhere to go.
- We strip out the old bead and clean off the residue left behind.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- You get a reopening time for every room, with signage left up until then.
Before we start on site
- Tell us your opening times and when work is allowed
- Arrange parking or a loading space
- Make sure the joints can be reached
