The process
We keep the work tidy and contained to the area we’re working on. Expect the work to take a few hours per room, so whole buildings are phased, and we tell you how long to leave it before we go. Somewhere as small as St Helens, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We walk the site with you and agree the rooms, the order and the hours.
- Every area is sheeted and the old silicone stripped out.
- The joints are degreased, treated and left to dry.
- New sealant suited to each area is applied and tooled.
- We check every room and give its cure time for housekeeping.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
Can I do it myself?
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What happens if it’s left?
Sealant work is quick by the room: it takes a morning for a small washroom, and a planned programme for bigger sites. Each area is then left to cure for the time we give you, so planning the order matters more than the hours on site. In a small place like St Helens, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What we cannot put right
We won’t take on work that will not last, so here’s what sealant can’t put right:
- A broken extractor fan behind the mould problem
- Failed tanking or loose tiles behind the sealant
- Damaged sanitaryware that needs replacing
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
Surfaces we seal
- Hotel bathrooms
- Office washrooms & kitchens
- Rental portfolios
- Retail & leisure sites
- Welfare facilities
- Student & care accommodation
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Log resealing so you know what’s due
- Report broken fans quickly
- Leave squeegees in busy showers
- Include the silicone on your room checklists
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix.
It’s easier to plan a programme than to react to failures. We can fit the work around bookings, shifts and opening hours, rather than closed at short notice.
What commercial sealant looks like in St Helens
For seaside hotels, guest houses and holiday lets around St Helens, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
If you look after a church, hall or community building such as St Catherine-by-the-Green, its kitchen and washroom sealant needs looking after like anywhere else. For site and facilities teams at buildings such as St Helens Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.
