Fire stopping near Beacon Hill

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Fire stopping in Beacon Hill, done properly

Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. Those on your schedule are closed with the specified product. The enquiries we see most involve damaged fire seals in risers and voids and seals that don’t match their tested detail, on pipe penetrations, joints between fire-resisting walls and floors and service gaps in risers. For commercial sealant work in Beacon Hill, you deal with one contact from quote to sign-off, whether it’s one building or several.

For a smaller site near Beacon Hill, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Walls or floors that aren’t fire-resisting to begin with
  • Deciding what a wall or floor needs, which belongs to the designer

If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Surfaces we seal

  • Small duct penetrations where the tested detail allows
  • Linear gaps at wall heads
  • Joints between fire-resisting walls and floors
  • Service gaps in risers
  • Cable penetrations
  • Pipe penetrations

Quoting for work in Beacon Hill

To price the job, we consider:

  • Distance, for remote addresses
  • How much existing material needs removing
  • How much there is to seal
  • The size and state of each joint

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What we need to price the job

There’s no need for a formal survey. A few details are enough to get going:

  • A wide shot and a close-up of the area
  • When you need the work done
  • The asbestos register, for older buildings
  • Where the site is, with the postcode

For a fixed quote, ring 01277 525 020 or email us with the site address and an outline of the work. You can also send details through our quote form.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Flag new cables with no seal around them
  • Record which product was used where
  • Get seals inspected before ceilings and boxing close
  • Don’t let anyone top up a fire seal with the wrong product

Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open.

Questions about Beacon Hill

Is Beacon Hill off your patch?

Not at all. Beacon Hill is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you design a fire-stopping scheme for our building in Beacon Hill?

No. The designer or fire engineer sets the detail and building control accepts it. We install what’s specified, to the product’s tested detail.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For work around Beacon Hill, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Tell us your opening times and when work is allowed
  • Clear stock, furniture or equipment away from the joints

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Advice

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Do you need fire stopping in Beacon Hill?

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.

It’s worth sending us details if you spot any of the following:

  • Fire seals cut back for extra cables and never reinstated
  • Unsealed joints where partitions meet the slab
  • Expanding foam used as fire stopping
  • Penetration schedules that need working through

For a school such as Great Totham Primary School, penetration sealing fits best at the end of the summer works.

Before you book anyone

  • What level of public liability insurance do they hold?
  • Whether primer will be used where the manufacturer specifies it
  • How the existing material will be dealt with
  • How joint depth will be controlled
