Fire rated sealant in Broad Oak

What we’re called out for in Broad Oak

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.

If you can see any of these, it’s time to have the joints looked at:

  • Gaps filled with a product that isn’t fire-rated
  • Fire stopping disturbed by later work
  • Holes left by a change of layout
  • Gaps around pipes and cables through fire-resisting walls

For landlords with property near Winchfield station, any gap left by new services in shared walls should be closed with a fire-rated product.

  • Whether they seal over old material or remove it

Choosing a sealant specialist

Fire rated sealant for homes and businesses in Broad Oak

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We’re often asked to deal with gaps around pipes and cables through fire-resisting walls and old fire sealant that has split or come away, 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 Broad Oak, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

Each job carries a 12-month guarantee, large or small.

Honest limits

We will always be straight with you, so here’s what sealant cannot fix:

  • Fire risk assessments, which need a qualified assessor
  • Construction that does not provide fire resistance on its own
  • Certifying a building or signing off its fire safety

If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

Broad Oak questions

I let a flat near Winchfield station. Can you help?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.

Is Broad Oak within the area you cover?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you offer different sealant colours?

Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.

Do the sealants smell?

It depends on the product. Some products have a noticeable smell, others very little.

Will you leave a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

What do you put in the joint?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.

Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.

Why act early in Broad Oak

An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the work involved is often modest. Where a wall is exposed, as many are in small places like Broad Oak, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

How to look after the new joints

How long the joints last depends on use and care. We suggest:

  • Ask which product was used before you paint
  • Photograph sealed gaps before they’re covered up
  • Allow for resealing whenever new services are run
  • Tell trades working in the building that fire seals must be put back

Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.

Fire rated sealant in Broad Oak: local notes

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

If you look after a building such as Mayhill Junior School, fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as All Saints Church, service openings in its walls need the right fire-rated sealant, as in any building.

Different surfaces, different methods

Service penetrations

New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.

Flats and HMOs

Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product and the locations noted.

What we do, step by step

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of gaps, and longer for a whole building and we leave things clean and tidy. Somewhere like Broad Oak needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  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. Every location is recorded with the product used for your records.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • Tell us about any previous sealing or DIY attempts
  • Tell us if parking is tricky
