What we do, step by step
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before we start. Most jobs take a morning for a small washroom, and a planned programme for bigger sites. In Chelsea, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height

About our commercial sealant in Chelsea
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. Products include Arbo and Everbuild sealants, chosen to suit each joint. Typical jobs include washroom sealant that looks dirty however often it’s cleaned and tired sealant ahead of a health and safety audit, across student & care accommodation, rental portfolios and welfare facilities.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in Chelsea, and room-by-room programmes can be planned where needed.
Whatever the size of the job, it’s backed by our one-year guarantee in Chelsea and across Greater London.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Common problems we fix in Chelsea
Quick fixes come back quickly. Sealing over old silicone, sealing wet joints or using the wrong product means the joint fails again soon.
The most common problems we see are:
- Failed floor-level joints in accessible wet rooms
- Mouldy washroom sealant that staff and guests notice
- Whole floors of tired en suites
- Washrooms that need sorting before an inspection
Managing a site like Oratory Roman Catholic Primary School? Then sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Landlord and commercial work in Chelsea
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
Why act early in Chelsea
Sealant work is quick by the room: it takes as long as the scope needs, from one welfare room to a full building. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Chelsea, the repair is bigger than a sealant job.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us and we’ll talk you through it.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Encourage users to squeegee shower walls
- Act on lifting sealant before it leaks
- Ask cleaners to go gently on the silicone
- Check the joints during routine room inspections
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix, and if anything looks wrong, just phone 0345 464 0079 or email us.
Mould in shared washrooms gets noticed and talked about. The longer it’s left, the deeper it grows into the silicone, and only replacement fixes it.
What the job involves on each surface
Rental portfolios
An empty property is easy to reseal, so the next tenant moves in to clean, sound joints.
Office washrooms & kitchens
In staff kitchens, we degrease joints before resealing, with a food-safe product beside sinks where needed.
