South Ruislip Fire Rated Sealant
We cover South Ruislip for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Seals cut through by electricians, plumbers or data installers
- Cracked or shrunken fire-rated sealant
- Standard silicone or caulk in a fire-stopping gap
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Never patch a fire seal with standard sealant
- Look in service cupboards and ceiling voids from time to time
- Make resealing part of every contractor’s brief
- File the fire-stopping record where your assessor can find it
Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
How we handle fire rated sealant in South Ruislip
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. If you have new service routes left unsealed after building work and gaps flagged on a fire risk assessment, we can help, whatever the surface.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in South Ruislip needs to stay open, work can be planned outside normal hours.
Every job is covered by a one-year guarantee, wherever you are in Greater London.

Your questions about fire rated sealant in South Ruislip
I let a flat near South Ruislip station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Is parking a problem for a job in South Ruislip?
Parking in South Ruislip, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you carry out fire risk assessments?
No, we don’t assess buildings. Once you have a specification or action list from your assessor or designer, we will quote for the sealant work on it.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before we start.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
What’s the difference between intumescent and fire-rated sealant?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
Will we have a record of what was sealed?
Yes. You get a list of where we worked and what we used.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Common problems we fix in South Ruislip
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
Look out for these signs:
- Gaps where walls meet ceilings or slabs
- Seals cut through by electricians, plumbers or data installers
- Gaps filled with a product that isn’t fire-rated
- Joints picked up in a fire-stopping survey
If you look after a church, hall or community building such as Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking.
What to look for in a quote
- How much experience the applicator has
- What the quote includes, VAT included or not
- How the colour is chosen
- How the joint is cleaned and prepared
Different surfaces, different methods
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service against the product’s tested range.
What affects the cost of fire rated sealant
The price is agreed before any work begins. It’s based on:
- Whether there’s mould to deal with
- The number of rooms or windows
- When we can work, for business premises
- The product the joint needs
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Asking for a quote
When you contact us, these details help:
- How we’d reach the joints
- The problem you’ve noticed
- Whether it’s a home or a business
- Where the property is
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
What fire rated sealant looks like in South Ruislip
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 work to the specification you are given, installing the product to its tested details. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
Managing a site like Deanesfield Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Rented homes near South Ruislip station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

The process

It helps if you can point us to a visitor permit or a bay close to the door.
- 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 and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
Before we arrive
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

Advice
Why it’s worth doing now in South Ruislip
Paying for fire stopping that has to be redone is a false economy. Work that does not follow the tested detail may have to come out again once someone inspects it. In a flat in South Ruislip, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear price before work begins.
