Fire rated sealant for East Horndon homes and businesses

Fire rated sealant in East Horndon, done properly

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. If you’re dealing with unsealed gaps where pipes and cables go through a wall and fire seals that have cracked with movement, we can put it right.

Work in a small place like East Horndon is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.

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

Why it’s worth doing now in East Horndon

If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. Around East Horndon, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Take a look at what affects the cost or what customers say.

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Looking after it afterwards

So the new joints stay in good condition:

  • Flag any open gap you spot round a pipe or cable
  • Look in service cupboards and ceiling voids from time to time
  • Check whether a sealant can be painted before decorating over it
  • Tell trades working in the building that fire seals must be put back

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint and we’ll tell you which one you have.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.

What we do, step by step

Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours for a handful of gaps, and longer for a whole building, depending on the amount of work. Somewhere like East Horndon needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Before we arrive

  • Let us know about earlier repairs to the joints
  • Plan for the work area to be out of bounds to pets and children
  • Try not to wet indoor joints just before the visit

Common questions in East Horndon

I let a flat near West Horndon station. Can you help?

Do you cover smaller places like East Horndon?

Yes, East Horndon is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Which products do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.

Do I need to be at home?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Where do you work from?

We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

Will you leave a mess?

We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.

What fire rating will the seal have?

We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.

Can you tell me which gaps need fire stopping?

No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.

  • Pictures of the joints, sent by email

What fire rated sealant looks like in East Horndon

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.

For buildings such as All Saints Church, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near West Horndon station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as West Horndon Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

How the job changes by surface

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the seal has something sound to bond to.

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run so there are no open sections left.
