Fire rated sealant for Northease homes and businesses

Fire rated sealant in Northease

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. Common call-outs are for gaps where walls meet ceilings or slabs and unsealed gaps around fire door frames, on flats & HMOs, linear gaps and service penetrations.

In a village or hamlet like Northease, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Different surfaces, different methods

Flats and HMOs

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

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each, and tell you if sealant alone isn’t the right fix.

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. A few tips:

  • Make resealing part of every contractor’s brief
  • Store the list of sealed gaps with your building paperwork
  • Allow for resealing whenever new services are run
  • Keep pictures of seals that will be hidden

Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.

Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Your questions about fire rated sealant in Northease

Is Northease within the area you cover?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you help a landlord with a rental near Southease station?

Yes, we work for landlords and agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.

Do you carry out fire risk assessments?

No. We follow the requirements from your assessor, designer or building control.

Is there any odour?

It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

Does someone need to be in?

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

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Do you remove the old sealant?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Do you take on fire stopping in schools and offices?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we’ll plan the work to suit.

Why deal with it now?

A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. Around Northease, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

Fire rated sealant around Northease

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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.

If you look after a church, hall or community building such as St Peter's Church, gaps around pipes and cables are worth checking after any building work there. Rented homes near Southease station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

When it isn’t the sealant

We will not take on work that will not last, so these are the limits:

  • Deciding what fire stopping a building needs
  • A wall that is not a fire-resisting element to begin with
  • Openings too large for sealant, which need batts, boards or another system

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

Where we work in Northease

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

How it works

We keep the work tidy and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours for a handful of gaps, and longer for a whole building, and we tell you how long to leave it before we go. In a small place like Northease, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your files.

How to prepare

  • Keep pets and children clear of the area while we work
  • Try not to wet indoor joints just before the visit
  • Tell us about access, such as stairs, a lift or high-level joints

Advice

When to call us in Northease

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.

Keep an eye out for any of the following:

  • Open holes round services passing through fire walls
  • Open joints along the top of partitions
  • Fire seals that have cracked with movement
  • Unsealed gaps around fire door frames

For site and facilities teams at buildings such as Priory School, gaps opened by contractors for new cabling are a common finding in schools and offices.

What to look for in a quote

  • Whether you can choose the colour
  • Whether they seal over old material or remove it
  • What happens if the job turns out different
  • Whether they’re fully insured

How to choose a mastic man

Can I do it myself?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
