Washroom sealing for commercial buildings in Keyhaven
When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. We work on urinals and WCs, kitchens and tea points and vanity units and basins, and what we’re called in for most is sealant stained black around basins and showers and gaps where vanity tops meet the wall. Looking for mastic applicators who cover Keyhaven? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Farm shops, cafés and venues in converted rural buildings around places like Keyhaven have busy toilets and kitchens. We plan the work around bookings and opening times.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Surface by surface
IPS and cubicle panels
Panel systems meet walls, floors and vanity tops at sealed joints. Those joints protect the boards behind from water.
Showers and trays
A tray that rocks or has cracked won’t be fixed by sealant, and we will say so before resealing.

What else we do in Keyhaven
On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes half a day to a day per washroom, depending on the number of fittings, and our waste is bagged and taken away as we go. For work around Keyhaven, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- We agree which rooms close and when, so users always have somewhere to go.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- We clean and dry every surface so the new sealant can grip.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- You get a reopening time for every room, with signage left up until then.
What we need from you
- Point out parking and an unloading spot
- Let us know about inductions and permits
- Share the asbestos register for older buildings

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Advice
Honest limits
Before quoting, we check that sealant is the right answer. It won’t put right:
- Mould caused by poor ventilation, which will return until the extract is fixed
- Hollow tiles or loose panels behind the joint
- Vanity carcasses that have swollen
If in doubt, phone 01277 525 020 or email us and we will say what we think before you book.

What sets the cost
To price the job, we consider:

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
What to include in your enquiry
Whether it’s one area or a whole building, the same details help:
- Approximate linear metres or a joint schedule
- How the joints are reached, and at what height
- When you need the work done
- Photos of the joints, close up and from further back
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email a schedule or drawings.
Do you need washroom sealing in Keyhaven?
Panels and vanity units move slightly in use, and shower trays shift under foot. If the joint wasn’t laid to take that movement, it tears or peels away.
Any of the following is a good reason to get the joints checked over:
- Discoloured joints around urinals and WC pans
- Sealant lifting along a tray edge
- Panel joints letting water behind
- A new bead over an old one coming away
Pupil toilets at schools like Milford-on-Sea Church of England Primary School take heavy daily use, and the holidays give the window to reseal.
Before you book anyone
- What site paperwork they can supply
- What the guarantee covers, and for how long
- Which product they’ll use, and why it suits the joint
- How the joint faces will be prepared and primed
Washroom sealing in Keyhaven: the local picture
Keyhaven is within about 1 mile of the coast, and seaside hospitality typically has a peak season that works washrooms hard. Washrooms used guest after guest wear their sanitary silicone faster, which is why off-season resealing makes sense. A 2-mile radius around Keyhaven takes in a number of hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest.
On a healthcare site such as Lymington New Forest Hospital, 3.4 miles to the north of Keyhaven, washroom work starts with the infection-control team’s sign-off. Halls linked to places like Church of All Saints host groups all week, which is hard on kitchen and toilet sealant.
Keyhaven is about 3 miles south of Lymington, in Hampshire. Any commercial site in Keyhaven is covered, for single jobs and planned programmes alike. Across Hampshire, 723 places are covered, including Keyhaven. There’s a separate page for Southampton, roughly 16 miles from Keyhaven.

Questions about Keyhaven
Is hospital work, at somewhere like Lymington New Forest Hospital, something you do?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Keyhaven off your patch?
Not at all. Keyhaven is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you do washroom sealing in healthcare settings?
Yes. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.
Why deal with it now?
Running fresh silicone along a failed bead hides the problem briefly. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Full removal and proper cleaning is what makes the new joint last. Converted and older buildings near places like Keyhaven tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
