Fire rated sealant for homes and businesses in Ayot Green
Deciding which gaps need fire stopping is not our role; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on plasterboard & masonry, pipe & cable gaps and flats & HMOs, and people most often call us about open gaps behind door architraves and seals cut through by electricians, plumbers or data installers.
Somewhere as small as Ayot Green, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Ask which product was used before you paint
- File the fire-stopping record where your assessor can find it
- Take pictures of fire stopping before ceilings or boxing go back
- Make resealing part of every contractor’s brief
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.
Why it’s worth doing now in Ayot Green
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. Around Ayot Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before any work starts.

Signs it’s time to call us include:
- Gaps flagged on a fire risk assessment
- Open gaps behind door architraves
- Gaps around pipes and cables through fire-resisting walls
- Old fire sealant that has split or come away

What happens on the day
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Ayot Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
How to prepare
- On commercial sites, let us know about site rules
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Ayot Green: your questions answered
Do you cover Ayot Green for fire rated sealant?
Yes. Our work covers London and the South East, and Ayot Green is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Welwyn Garden City station?
Yes. We work for landlords and agents as well as homeowners. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you carry out fire risk assessments?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job.
Do you take on fire stopping in schools and offices?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use, with access planned around residents or staff. Out-of-hours work can be arranged if that suits the building.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Fire rated sealant around Ayot Green
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.
Schools such as Monk's Walk School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Community buildings like Church of St Peter are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
