How we handle fire stopping in Bredhurst

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. We work on service gaps in risers, pipe penetrations and joints between fire-resisting walls and floors, and the failures we’re asked to look at most are old intumescent sealant that has split away and improvised or mixed-product fire seals. Looking for mastic applicators who cover Bredhurst? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

A job near Bredhurst is typically planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

How the job changes by surface

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range.

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do and we will tell you what the detail says instead.

Do you need fire stopping in Bredhurst?

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.

If one of these sounds familiar, it’s time for a closer look:

  • Penetration schedules that need working through
  • Hidden openings found during inspections
  • Improvised or mixed-product fire seals
  • Fire seals cut back for extra cables and never reinstated

For an estates team at a campus like University for the Creative Arts - Rochester (4.3 miles north-west of Bredhurst), summer M&E works are normally followed by a round of penetration sealing.

How to choose a sealant contractor

Why act early in Bredhurst

The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. Converted and older buildings near places like Bredhurst tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Why us?

  • Failed material removed, not covered up
  • Fully insured
  • Clear, fixed quotes
  • CHAS accredited contractor

Take a look at how commercial sealant jobs are priced or our accreditations.

What sets the cost

To price the job, we consider:

  • The product specified
  • How much there is to seal
  • The site’s rules and procedures
  • Joint width, depth and condition

Pricing service penetrations depends on quantities, condition and access. Ask us for a fixed quote.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them
  • Specification clauses that apply
  • The type of building and who uses it

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or email drawings and photos.

Commercial clients in Bredhurst

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Bredhurst, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings

Getting a fixed quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
