About our fire rated sealant in Knapp
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. We work on plasterboard & masonry, linear gaps and flats & HMOs, and the jobs we see most are sealant items on a fire risk assessment action list and unsealed gaps around fire door frames.
In a village or hamlet like Knapp, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Take pictures of fire stopping before ceilings or boxing go back
- Include fire stopping when you schedule refits
- Ask which product was used before you paint
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.
Other services in Knapp
Different surfaces, different methods
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service to make sure it suits the product.
The process
At the end, we look at the finished work together. The visit itself generally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. Somewhere like Knapp 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.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.
Getting ready for the visit
- Tell us about any water getting in
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height

Workplaces and buildings in Knapp
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 work to the specification you’re given, installing the product to its tested details.
Managing a site like Ampfield Church of England Primary School? Then fire-stopping around service openings should be restored whenever new services go in. If you let a flat or house near Chandlers Ford 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 Mark, service openings in its walls need the right fire-rated sealant, as in any building.

Questions from Knapp
Will you come out to Knapp?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Chandlers Ford station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We’ll tell you when we quote.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Will we have a record of what was sealed?
Yes. We record the locations we have sealed and the products used to keep with your fire safety documents.
Are you fully insured?
Yes. We’re fully insured for domestic and commercial work.
Do you seal gaps around fire door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product. The door, its seals and closer are for a door specialist.
Why act early in Knapp
Sealant is not 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. Older cottages and farmhouses around Knapp can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
