How we handle fire rated sealant in Sacombe Green
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over. Common call-outs are for gaps flagged on a fire risk assessment and ordinary sealant used where a fire-rated product was needed, across pipe & cable gaps, flats & HMOs and door frames.
For holiday lets, converted business premises or a community building near Sacombe Green, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
A one-year guarantee comes with the work, just as it does everywhere we cover.

For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Fire risk assessments, which need a qualified assessor
- Big openings where sealant alone isn’t the tested solution
- Doors that aren’t fire doors in the first place
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.

Flats and HMOs

Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
Commercial buildings in Sacombe Green
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Managing a site like Ralph Sadleir Middle School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. For landlords with property near Watton-At-Stone station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as Church of St Katherine, service openings in its walls need the right fire-rated sealant, as in any building.

What happens if it’s left?
Sealant isn’t the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We will say so if a gap needs something other than sealant. In a small place like Sacombe Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

Is intumescent sealant the same as fire-rated sealant?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Will we have a record of what was sealed?
Yes. When the job is done, we give you the locations and products. If you need photos or a set layout, ask when you get a quote.
