The process
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a single washroom, longer for a whole building for a typical job. Somewhere as small as Dunton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We agree a programme with you: which rooms, in what order, at what times.
- 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.
- We reseal with the right product for each joint.
- Rooms are handed back in order, each with its cure time.
Before we arrive
- Clear the area around the work
- Tell us about any water getting in
- Mention if the joints have been sealed before

Honest limits
In fairness, there are a few things sealant won’t fix:
- Leaking pipework, valves or wastes (a plumber’s job)
- A shower tray, bath or basin that is cracked or broken
- Extraction that is not working, which needs an electrician or ventilation contractor
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal

Commercial buildings in Dunton
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a church, hall or community building such as Church of St Martin, its kitchen and washroom sealant needs looking after like anywhere else.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Log resealing so you know what’s due
- Schedule work around occupancy
- Report broken fans quickly
- Act on lifting sealant before it leaks
A squeegee in each shower is a simple help: less water sits on the joints between uses.
It’s easier to plan a programme than to react to failures. Rooms can be scheduled around occupancy and staff, instead of rooms closing without warning.
Should I try it myself first?
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Should I try DIY first?

What does commercial sealant cost?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
What affects the cost of commercial sealant
We quote each job individually. This is what makes a difference:
- The number of rooms or windows
- The type of sealant required
- The old material and how stubborn it is
- When we can work, for business premises
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- Roughly how big the job is
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- How we’d reach the joints
Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.
Do you need commercial sealant in Dunton?
Shower trays and baths in busy buildings move more: people of all sizes, daily cleaning and constant loading all work at the joint. If a tray flexes, the sealant around it splits.
The problems people usually mention when they call include:
- Leaking joints in shower rooms and changing areas
- Washrooms that need sorting before an inspection
- Sealant failing again soon after quick repairs
- Mouldy washroom sealant that staff and guests notice
In and around Dunton, as anywhere, good commercial sealant starts with a clean, dry, properly prepared joint.
