Surface by surface

Service penetrations

Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.

Flats and HMOs

Conversions generally leave a mix of old and new service holes. We seal the ones on your specification with a tested product and record where they are.

How we handle fire rated sealant in Hillborough

Bigger jobs can be worked through in stages, flat by flat or floor by floor, noting the locations and products as we go. It gives you a list to keep with the building’s fire safety documents. If you are dealing with gaps left after a refit or conversion and damaged fire sealant left by other trades, we can help.

If you run a pub, café, guest house or shop in or near Hillborough, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.

You’re covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Questions from Hillborough

Is Hillborough in your area for fire rated sealant?

Yes. We work across London and the South East, and Hillborough is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.

I let a flat near Herne Bay station. Can you help?

Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.

Where are you based?

Our base is in Crawley, and we work across South East England, London and Scotland.

Can you match the sealant colour?

In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before we start.

Is it messy?

We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.

What sealant do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.

Can you tell me which gaps need fire stopping?

No, assessment is not something we do. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.

Is intumescent sealant the same as fire-rated sealant?

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.

Common problems we fix in Hillborough

Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.

The most common problems we see are:

  • Cracked or shrunken fire-rated sealant
  • Holes left by a change of layout
  • Linear gaps at the head of walls
  • Door frames with gaps between frame and wall

If you look after a church, hall or community building such as Church of St Mary the Virgin, service openings in its walls need the right fire-rated sealant, as in any building.

Questions to ask before you book

  • What the cure time is
  • What happens if the job turns out different
  • What the quote includes, VAT included or not
  • How the joint is cleaned and prepared

Choosing a sealant specialist

DIY sealant or a professional job?

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. All the old material has to come out first.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

What we do, step by step

The work is kept neat and contained to the joints we are treating, so you can get on with your day. Expect the work to take anything from a few hours to several days, depending on how many gaps there are, and we explain the cure time before we leave. For a job in Hillborough, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How we quote for fire rated sealant

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

  • Any working-time requirements on site
  • Whether the work is at height
  • How many areas need sealing
  • The old material and how stubborn it is

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What we need to know

To make quoting easier, let us know:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Whether it has been sealed before
  • Access, such as stairs, a lift or height
  • If it’s domestic, commercial or a hotel

Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand.

What fire rated sealant looks like in Hillborough

If you run a hotel, guest house or holiday let in a coastal place like Hillborough, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 work to the specification you’re given, installing the product to its tested details.

If you look after a building such as Reculver Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment. Rented homes near Herne Bay station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Hillborough is about 2 miles east of Herne Bay, in Kent. Jobs in Hillborough get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. Hillborough is one of 922 towns and villages in Kent we cover for fire rated sealant. You can also see our page for Chelmsford, roughly 39 miles from Hillborough.

What we cannot put right

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

  • Certifying a building or signing off its fire safety
  • Fire risk assessments, which need a qualified assessor
  • A wall that isn’t a fire-resisting element to begin with

If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Surfaces we seal

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

What happens if it’s left?

Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own that doesn’t depend on other work. Around Hillborough, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.
