Fire rated sealant near Heart's Delight

Fire rated sealant in Heart's Delight

Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. Common call-outs are for gaps flagged on a fire risk assessment and door frames with gaps between frame and wall, on flats & HMOs, linear gaps and pipe & cable gaps.

If you have holiday lets, a converted barn used for business or a community building near Heart's Delight, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

There’s a 12-month guarantee on every job, whatever its size.

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Questions from Heart's Delight

Do you cover smaller places like Heart's Delight?

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you cover Heart's Delight for fire rated sealant?

Yes. Our work covers London and the South East, and Heart's Delight is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.

What’s the difference between intumescent and fire-rated sealant?

Intumescent means it swells when heated. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

Can I do it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

What sealant 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.

Can you give us a record of the work?

Yes. Every gap we seal is listed with the product used.

Do you carry out fire risk assessments?

No. We work from the specification you give us and install to the manufacturer’s details.

Do I have to be there?

That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.

Do you need fire rated sealant in Heart's Delight?

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. We see plenty of fire stopping that was hurried.

Most people get in touch after spotting one of these:

  • Linear gaps at the head of walls
  • Fire stopping disturbed by later work
  • Sealant items on a fire risk assessment action list
  • Open gaps behind door architraves

Schools such as Barham Church of England Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Questions to ask before booking

  • Which sealant they’ll use, and why
  • How much experience the applicator has
  • Whether they’re fully insured
  • What happens if the job turns out different

Our hiring checklist

How the job changes by surface

Masonry and concrete

Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it.

Door frames

We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist and we will mention anything we notice.

For landlords and businesses

We also work for property managers and facilities teams in Heart's Delight and across Kent. We can quote a run of properties together, and we are fully insured for the work.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

When something else is needed

A few problems are outside what sealant work can do:

  • Large holes that need a different fire-stopping system
  • Walls or floors that weren’t built to resist fire
  • Assessing a building’s fire safety

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

Joints and surfaces we work on

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

How the visit works

On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before we start. 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 Heart's Delight, access is normally 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. Any non-fire-rated filler is removed.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your files.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • For business premises, tell us about site rules or sign-in
  • Clear the area around the work

Advice

Fire rated sealant around Heart's Delight

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 Snowdown station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as Church of St John the Baptist, older buildings that have had new heating or wiring often have service gaps worth checking.

Why deal with it now?

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. Where a wall is exposed, as many are in small places like Heart's Delight, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

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.
