- Large holes that need a different fire-stopping system
- Fire risk assessments, which need a qualified assessor

Fire rated sealant in Harefield
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. We seal them with a product tested for that kind of gap. If you’re dealing with seals cut through by electricians, plumbers or data installers and fire seals that have cracked with movement, we can put it right, whatever the surface.
In a smaller place like Harefield, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.
All of our work is guaranteed for twelve months.

Common questions in Harefield
Will you come out to Harefield?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Bitterne station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can you tell me which gaps need fire stopping?
No, assessment is not something we do. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.
Can ordinary silicone be used in a fire-stopping gap?
No. Ordinary silicone, caulk or foam is not tested as fire stopping. We cut it out and reseal with a fire-rated product.
How long will you be here?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We’ll tell you when we quote.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
What fire rating will the seal have?
We don’t give ratings or certificates for our work. The requirement comes from your assessor, designer or building control, and we apply a product tested for it, recording the locations and products.
For landlords and businesses
For anyone letting property in or around Harefield, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What fire rated sealant looks like in Harefield
For seaside hotels, guest houses and holiday lets around Harefield, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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.
If you let a flat or house near Bitterne station, 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 Harefield Primary School, fire-stopping around service openings should be restored whenever new services go in. Community buildings like Church of St James are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

What affects the quote in Harefield
For a quick quote, just ask. The main things that affect it are:
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- The number and length of the joints
- The type of sealant required

- Any access issues, like height or stairs

How it works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of gaps, and longer for a whole building in most cases.

- 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.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

Related advice
Leave it or put it right?
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 work involved is often modest. Homes in smaller places like Harefield can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

Different surfaces, different methods
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the sealant bonds.
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run.
