DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Where are you based?

How long does fire rated sealant take?
Typically it takes from a few hours to a few days, depending on the number of gaps and the access. Larger jobs naturally take longer.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
What does intumescent mean?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant.
Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Plan fire stopping into any work that goes through walls or floors
- Report cracked or damaged seals as soon as you notice them
- Include hidden areas like risers in routine checks
- Never patch a fire seal with standard sealant
Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the job gets bigger.

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.
These are the problems we are asked about most:
- Damaged fire sealant left by other trades
- Gaps around pipes and cables through fire-resisting walls
- Ordinary sealant used where a fire-rated product was needed
- Holes left by a change of layout
In and around Underling Green, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.
