Fire stopping for Hightown sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How the job changes by surface

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening.

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.

Fire stopping in Hightown

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, phone 01277 525 020 or send details through our quote form with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. We work on pipe penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors, and what we’re called in for most is openings left by services added after handover and builders’ foam or ordinary silicone in compartment walls. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Hightown is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller places such as Hightown still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Hightown: questions and answers

Can you seal penetrations in a hotel in Hightown after a refit?

Yes, where fire-rated sealant is the specified product. Each seal follows the tested detail, and rooms are done in turn.

Is Hightown too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or send photos by email. Include photographs or drawings if you have them.

What sealant work can’t fix

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Signing off or certifying a building’s fire stopping

Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly.

Where we work in Hightown

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

When to call us in Hightown

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.

Any of the following is a good reason to get the joints checked over:

  • Damaged fire seals in risers and voids
  • Fire-stopping items raised at inspection or handover
  • Open linear gaps along the top of fire-resisting walls
  • Builders’ foam or ordinary silicone in compartment walls

In a building such as St John the Baptist, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Choosing a commercial sealant contractor

Our process

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Hightown, 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 ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work
  • Tell staff and tenants when we will be in

Why deal with it now?

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is typically a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Older rural buildings around Hightown move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Why clients in Hightown choose us

  • Commercial sealant work since 2005
  • A Constructionline member, so easy to vet
  • Our applicators hold CSCS cards
  • Specification-led, product-correct work

See what affects the cost or our accreditations.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Fire stopping in Hightown: the local picture

Several hotels sit less than 2 miles from Hightown. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. There are four care or nursing homes within about 2 miles of Hightown. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.

Hotels like The Crown Hotel, 1.2 miles west of Hightown, are refurbished in phases, and each phase can open up compartment walls. Workshops and IT rooms at colleges like Sheiling College, 2.2 miles to the west of Hightown, are re-serviced often, leaving penetrations to seal.
