Workplaces and buildings in Winchmore Hill
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. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
Winchmore Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Rented homes near Winchmore Hill station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For site and facilities teams at buildings such as St. Paul's School, fire-stopping around service openings should be restored whenever new services go in.

What else we do in Winchmore Hill
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Make resealing part of every contractor’s brief
- Do not paint over fire sealant until it has cured
- Check risers, ceiling voids and cupboards during building checks
- Take pictures of fire stopping before ceilings or boxing go back
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

Common questions in Winchmore Hill
Do you cover Winchmore Hill for fire rated sealant?
Yes, Winchmore Hill is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.

Yes, we work for landlords and agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants are not made or tested to stop fire. We cut it out and reseal with a fire-rated product.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What does intumescent mean?
An intumescent sealant expands when it gets hot, helping close the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Surface by surface
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details before the trim goes back.
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail, and we’ll tell you.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on how many gaps there are and we leave things clean and tidy. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Winchmore Hill. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on
- Mention if the joints have been sealed before

Why it’s worth doing now in Winchmore Hill
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Winchmore Hill, the repair is bigger than a sealant job.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
