Trusted fire rated sealant in Horley

Fire rated sealant for homes and businesses in Horley

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. 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. We work on door frames, pipe & cable gaps and service penetrations, and the jobs we see most are unsealed gaps where pipes and cables go through a wall and old fire sealant that has split or come away.

For anyone managing a school, care home, pub or office in Horley, washroom sealant, kitchen joints and fire-rated sealant around service openings all need upkeep. Work can be planned around opening hours where needed.

A 12-month guarantee comes as standard, so you are covered after we’ve gone.

What happens on the day

There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Horley, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.

  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. Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
  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 records.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • Mention if the joints have been sealed before
  • Tell us about access, such as stairs, a lift or high-level joints

Advice

Common questions in Horley

Can you do fire rated sealant in Horley?

Yes. We work across London and the South East, and Horley is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.

Do you work for hotels and guest houses in Horley?

Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.

Is it worth trying it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

How long does fire rated sealant take?

A typical job takes anything from a few hours to several days, depending on how many gaps there are, including preparation and clearing up. Your quote will say how long we expect yours to take.

Can you tell me how many minutes the seal will last?

Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and list the locations and products for you.

What does fire rated sealant cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.

What sealant do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.

Is it OK to seal over old sealant?

No. We remove every bit of old sealant first, so the new sealant bonds properly.

What the job involves on each surface

Service penetrations

New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth over any backing the detail calls for.

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail and we’ll flag it.

How to look after the new joints

Good habits help new joints last longer. A few tips:

  • Tell trades working in the building that fire seals must be put back
  • Report cracked or damaged seals as soon as you notice them
  • Check whether a sealant can be painted before decorating over it
  • Never patch a fire seal with standard sealant

Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.

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.

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

Leave it or put it right?

Sealant is not the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. In a family home in Horley, a failed seal around a bath or a frame lets water into places you cannot see, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.

Fire rated sealant in Horley: local notes

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. There are hotels and other places to stay in and around Horley. Hotel work can be planned room by room, with out-of-hours working where needed.

If you let a flat or house near Horley station, any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as St Wilfrid's Church, gaps around pipes and cables are worth checking after any building work there.

What we are called out for in Horley

Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. Rushed fire stopping is common.

Most people get in touch when they notice something like this:

  • New service routes left unsealed after building work
  • Seals cut through by electricians, plumbers or data installers
  • Ordinary sealant used where a fire-rated product was needed
  • Old fire sealant that has split or come away

Managing a site like Horley Infant School? Then fire-stopping around service openings should be restored whenever new services go in.

Questions to ask before booking

  • Is the old sealant removed completely?
  • Who does the work, and how experienced they are
  • How hidden problems are handled
  • When the joint can take water or movement
