Service penetrations

Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone is not the right fix.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified.

How we handle fire rated sealant in Coursehorn

A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That’s the part we focus on. Typical jobs include gaps around pipes and cables through fire-resisting walls and open gaps behind door architraves, across door frames, pipe & cable gaps and service penetrations.

For a small place like Coursehorn, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Fire rated sealant in Coursehorn: local notes

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Managing a site like Cranbrook School? Then service openings in fire-resisting walls need checking after any refurbishment.

What happens if it’s left?

Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. In a small place like Coursehorn, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

Why book with us

  • Fully insured
  • A 12-month guarantee on all work
  • Tidy, careful work
  • Domestic, commercial and hotel work

Take a look at what affects the cost and our reviews.

What affects the cost of fire rated sealant

We don’t publish a price list, because no two jobs are the same. The quote depends on:

  • The number and length of the joints
  • The type of sealant required
  • Whether there’s mould to deal with
  • The old material and how stubborn it is

We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.

What to tell us for a quote

Photos by email are helpful but not essential. Try to tell us:

  • What’s wrong with the joints now
  • Photos by email, if that is easy
  • If someone has resealed it before
  • How we’d reach the joints

To get a quote, phone 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You will have a clear quote before any work starts.

When to call us in Coursehorn

Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried.

It’s worth asking for a quote if you see:

  • Seals cut through by electricians, plumbers or data installers
  • Gaps where walls meet ceilings or slabs
  • Cracked or shrunken fire-rated sealant
  • Holes left by a change of layout

If you look after a church, hall or community building such as Church of St Dunstan, gaps around pipes and cables are worth checking after any building work there.

What your quote should include

  • How long the guarantee is
  • Whether the sealant suits the joint
  • Whether they seal over old material or remove it
  • What the cure time is

10 questions to ask before you book

What sealant work cannot fix

In fairness, some problems need a different trade:

  • Construction that does not provide fire resistance on its own
  • Big openings where sealant alone isn’t the tested solution
  • Doors that are not fire doors in the first place

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.

What we seal

  • Service penetrations
  • Door frames
  • Pipe & cable gaps
  • Flats & HMOs
  • Plasterboard & masonry
  • Linear gaps

Should I try it myself first?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What happens on the day

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to several days, depending on how many gaps there are from start to finish. In a small place like Coursehorn, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • Keep pets and children clear of the area while we work
  • Mention if the joints have been sealed before
  • Mention any tricky access

How to get a quote

Asking for a quote is easy: tell us what needs doing and where. A few photos by email make the job easier to understand, and we will come back to you with a quote.
