We regularly work with letting and managing agents. Tell us the address, the job and how access works.

In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.

Fire rated sealant in Bury Green, done properly

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you are dealing with door frames with gaps between frame and wall and open joints along the top of partitions, we can help.

Work in a small place like Bury Green is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

A 12-month guarantee comes as standard.

How the visit works

We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and 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 Bury Green, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • For business premises, tell us about site rules or sign-in
  • Mention any tricky access

Keeping the joints in good condition

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

  • Check risers, ceiling voids and cupboards during building checks
  • Include fire stopping when you schedule refits
  • Get damaged fire seals looked at promptly
  • Take pictures of fire stopping before ceilings or boxing go back

Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded so you can show it was dealt with.

Leave it or put it right?

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job. In a small place like Bury Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

Surface by surface

Service penetrations

A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each and we flag any that need another system.

Linear gaps

A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.

When it isn’t the sealant

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

  • Doors that aren’t fire doors in the first place
  • Big openings where sealant alone is not the tested solution
  • A wall that is not a fire-resisting element to begin with

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

Joints and surfaces we work on

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

DIY versus a professional finish

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

FAQs for Bury Green

I let a flat near Bishops Stortford station. Can you help?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.

Do you cover Bury Green for fire rated sealant?

Yes, Bury Green is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.

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

Ratings and certificates aren’t something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.

Is it OK to seal over old sealant?

No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Where do you work from?

We work from Crawley. We cover Bury Green and the rest of Hertfordshire, along with the rest of our area.

Will we have a record of what was sealed?

Yes. Locations and products are written up when we finish. If you need photos or a set layout, ask when you get a quote.

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

An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all and which one is used depends on the job.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Fire rated sealant in Bury Green: 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 work to the specification you’re given, installing the product to its tested details.

For landlords with property near Bishops Stortford station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as Parish Church of St Cecilia, service openings in its walls need the right fire-rated sealant, as in any building. For site and facilities teams at buildings such as Little Hadham Primary School, fire-stopping around service openings should be restored whenever new services go in.
