Fire rated sealant for Hill End homes and businesses

Fire rated sealant for homes and businesses in Hill End

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. Typical jobs include unsealed gaps around fire door frames and open joints along the top of partitions, on flats & HMOs, plasterboard & masonry and door frames.

If you have holiday lets, a converted barn used for business or a community building near Hill End, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

All our work comes with our 12-month guarantee.

How it works

The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job usually takes anything from a few hours to several days, depending on how many gaps there are, and we tell you how long to leave it before we go. In a small place like Hill End, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. We record the locations and products used for your records.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks
  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us if parking is tricky

What the job involves on each surface

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.

Flats and HMOs

In occupied buildings, we plan the order of work with you. Access to flats and common areas is agreed in advance to keep disruption down.

Your questions about fire rated sealant in Hill End

Do you work for landlords with property near Rickmansworth station?

Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.

Do you cover smaller places like Hill End?

Yes. Hill End is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you quote for more than one area?

Yes. Just list everything you need and we will quote it together.

Do I have to be there?

It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

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.

Do you guarantee your work?

Yes. Each job is guaranteed for twelve months, large or small.

How do I get a quote for fire rated sealant in Hill End?

It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or drop us an email with a short description of the job.

Which products do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Fire rated sealant around Hill End

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, 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.

Rented homes near Rickmansworth station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as Harefield Baptist Church, gaps around pipes and cables are worth checking after any building work there. Managing a site like Harefield Infant School? Then fire-stopping around service openings should be restored whenever new services go in.

Looking after it afterwards

So the new joints stay in good condition:

  • Never patch a fire seal with standard sealant
  • Allow for resealing whenever new services are run
  • Take photos of fire stopping before ceilings or boxing go back
  • File the fire-stopping record where your assessor can find it

File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

Can I do it myself?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

What affects the cost of fire rated sealant

The quote reflects the job in front of us. We look at:

  • Any working-time requirements on site
  • Whether there’s mould to deal with
  • How much old sealant there is and how hard it is to remove
  • How easy the joints are to reach

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What we need to know

There’s no need for technical detail. Just tell us:

  • How many joints, rooms or windows are involved
  • How we’d reach the joints
  • If someone has resealed it before
  • What the problem is, such as mould, gaps, leaks or cracking

Need a quote? Please ring 0345 464 0079 or send us an email and tell us about the job. We’ll explain what we’d do and send you a clear quote before work begins.

What happens if it’s left?

A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. In a small place like Hill End, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What sealant work can’t fix

It helps to know what we can’t do:

  • A wall that isn’t a fire-resisting element to begin with
  • Big openings where sealant alone isn’t the tested solution
  • Fire doors that need new seals, closers or hardware

If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
