Fire Rated Sealant in Arnos Grove
Intumescent and fire-rated sealant around gaps, frames and service penetrations for homes and businesses in Arnos Grove and across Greater London. Fully insured, ARBOMaster approved and guaranteed for a year.
- Gaps flagged on a fire risk assessment
- Gaps filled with a product that is not fire-rated
- Door frames with gaps between frame and wall
Can I do it myself?
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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Fire rated sealant in Arnos Grove
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. Common call-outs are for ordinary sealant used where a fire-rated product was needed and old fire sealant that has split or come away, across plasterboard & masonry, door frames and service penetrations.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Arnos Grove, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Keep the record of products and locations with your fire safety documents
- Get damaged fire seals looked at promptly
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Look in service cupboards and ceiling voids from time to time
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
Fire rated sealant around Arnos Grove
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Letting a property close to New Southgate station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Schools such as Bowes Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Arnos Grove is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Every job gets its own quote. These are the things that affect it:

Asking for a quote
When you call or email, it’s useful to know:
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- Access, such as stairs, a lift or height
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Why deal with it now?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Arnos Grove, the repair is bigger than a sealant job.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
