Why it’s worth doing now in Herongate

Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job and needn’t wait for anything else. Around Herongate, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Why us?

  • Homes, businesses and hotels
  • We never seal over old sealant
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Arbo and Everbuild products

About our fire rated sealant in Herongate

Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. We work on service penetrations, plasterboard & masonry and flats & HMOs, and people most often call us about gaps around pipes and cables through fire-resisting walls and gaps where walls meet ceilings or slabs.

For holiday lets, converted business premises or a community building near Herongate, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Common problems we fix in Herongate

Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it is not fire-rated.

The most common problems we see are:

  • Holes left by a change of layout
  • Door frames with gaps between frame and wall
  • Fire seals that have cracked with movement
  • Open joints along the top of partitions

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

Questions to ask before you book

  • What product goes in the joint

What fire rated sealant looks like in Herongate

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.

For site and facilities teams at buildings such as Brentwood County High School, fire-stopping around service openings should be restored whenever new services go in. Letting a property close to West Horndon station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

How it works

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In a small place like Herongate, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your files.

Preparing for the visit

  • Tell us about any water getting in
  • Clear items away from the joints we’re working on
  • Tell us about access, such as stairs, a lift or high-level joints

Questions from Herongate

Can you do fire rated sealant in Herongate?

Yes, Herongate is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.

Will you come out to Herongate?

Yes, Herongate is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

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.

Can ordinary silicone be used in a fire-stopping gap?

No. Where a fire-rated seal is needed, it has to be a product tested for that use.

Can you match the sealant colour?

In most cases you can choose. We’ll explain which colours are available.

Do you take on fire stopping in schools and offices?

Yes. We regularly work in flats, HMOs, schools and offices while they’re in use. Early starts or out-of-hours work can be arranged.

Are you ARBOMaster approved?

Yes. We are approved under the ARBOMaster scheme.

Do the sealants smell?

Possibly a little. It fades as the sealant cures, and ventilation helps.

DIY sealant or a professional job?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

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 fails, we can still redo it.

Different surfaces, different methods

Service penetrations

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

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
