When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Doors that aren’t fire doors in the first place
- Assessing a building’s fire safety
- Openings too large for sealant, which need batts, boards or another system
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.
Joints and surfaces we work on

Fire rated sealant in Fernham
We often work from an action list drawn up by a fire risk assessor. If you share the list, we can quote for the gaps that need fire-rated sealant. We’re often asked to deal with holes left by a change of layout and damaged fire sealant left by other trades, across flats & HMOs, plasterboard & masonry and service penetrations.
Work in a small place like Fernham is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

What happens on the day
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Fernham needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your records.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Mention any tricky access

Advice
Other services in Fernham
Aftercare tips
A little care helps the new joints last. We recommend:
- Report cracked or damaged seals as soon as you notice them
- Allow for resealing whenever new services are run
- Check whether a sealant can be painted before decorating over it
- Ask every contractor to reseal any fire stopping they disturb
Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded.
What happens if it’s left?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Fernham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Different surfaces, different methods
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail, and we’ll tell you.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Workplaces and buildings in Fernham
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, 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.
For site and facilities teams at buildings such as Faringdon Community College, fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as Church of St John, gaps around pipes and cables are worth checking after any building work there.
