Trusted fire rated sealant in Elsenham

Do you need fire rated sealant in Elsenham?

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.

People normally contact us when they notice something like this:

  • Old fire sealant that has split or come away
  • Seals cut through by electricians, plumbers or data installers
  • Open holes round services passing through fire walls
  • New service routes left unsealed after building work

If you look after a church, hall or community building such as Church of St Mary the Virgin, older buildings that have had new heating or wiring often have service gaps worth checking.

Choosing a sealant specialist

Fire rated sealant for homes and businesses in Elsenham

Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We are often asked to deal with ordinary sealant used where a fire-rated product was needed and unsealed gaps where pipes and cables go through a wall, across pipe & cable gaps, door frames and flats & HMOs.

Around a place like Elsenham, halls, schools and small businesses all have washrooms and kitchens used by many people. Their sealant and fire-rated joints are as important as those in any bigger building.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Common questions in Elsenham

Do you cover smaller places like Elsenham?

Yes. Elsenham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you do fire rated sealant in Elsenham?

Yes, Elsenham is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.

Is it OK to seal over old sealant?

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

What does intumescent mean?

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.

Is standard sealant good enough for a fire gap?

No. It looks sealed but won’t perform as fire stopping. Use a product tested for that gap and service.

How long will you be here?

As a guide, most jobs take from a few hours to a few days, depending on the number of gaps and the access. Larger jobs naturally take longer.

Do you have insurance?

Yes. We are fully insured, and we have been doing sealant work for more than 20 years.

Where do you work from?

Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

When something else is needed

We’d rather tell you now than do work that won’t last, so these are the limits:

  • Deciding what fire stopping a building needs
  • Construction that doesn’t provide fire resistance on its own
  • Large holes that need a different fire-stopping system

If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Where we work in Elsenham

  • Service penetrations

For landlords and businesses

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Should I try it myself first?

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

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

The process

We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. The job usually takes 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 smaller place like Elsenham, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Getting ready for the visit

  • Tell us about any previous sealing or DIY attempts
  • Mention any tricky access
  • Clear the area around the work

Masonry and concrete

Commercial buildings in Elsenham

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 work to the specification you are given, installing the product to its tested details.

Rented homes near Elsenham station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For site and facilities teams at buildings such as Forest Hall School, service openings in fire-resisting walls need checking after any refurbishment.
