About our washroom sealing in Downside
For clinics, hospitals and care homes, sealed joints matter for infection control as much as appearance. We work to your organisation’s estates and infection-control requirements and any site permits. Any records you need are confirmed with the quote. If you have discoloured joints around urinals and WC pans and gaps where vanity tops meet the wall, we can put it right. A specialist sealant contractor works differently from a general builder: in Downside, that means joint design, primers and backing rod as standard.
In and around smaller places like Downside, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Quoting for work in Downside
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Travel to remote or island sites
- Access and working height
- The total length or number of joints
- Which sealant the job calls for
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What to include in your enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Whether the building will be occupied during the work
- Any specification or named product
- Photos of the joints, close up and from further back
- When you need the work done
Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. If you have questions first, call 01277 525 020 or use the quote form.
Honest limits
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Hollow tiles or loose panels behind the joint
- Water escaping beneath the floor rather than through a joint
- Swollen or delaminated boards behind panels or vanity tops
If you’re not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer.
Surfaces we seal
- Accessible toilets and changing rooms
- Urinals and WCs
- Vanity units and basins
- Showers, trays and wet room floors
- Kitchens and tea points
- IPS panels and cubicles
Doing it in-house
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
How a job runs
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking a few hours for one toilet block, with bigger buildings phased across a number of visits. Jobs in and around smaller places like Downside are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- 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.
- Joints are cleaned, degreased and dried before sealing.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Each room is handed back once the sealant has had its cure time.
What we need from you
- Arrange parking or a loading space
- Share the asbestos register for older buildings
- Clear stock, furniture or equipment away from the joints

After the work
After handover, a little attention goes a long way:
- Squeegee showers and trays after busy periods
- Don’t leave an open joint at a basin or tray
- Brief cleaning staff to treat joints gently
- Keep extract fans working and vents clear
Keep extract fans working and vents clear. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.
Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.
Common questions from Downside clients
Is Downside too small for you to travel to?
Not at all. Downside is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Will you work in a care home in Downside without moving residents out?
Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Will cleaning remove black mould from sealant?
Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.

How the job changes by surface

A tray that rocks or has cracked won’t be fixed by sealant and we flag that beforehand.
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.
