Fire stopping near Fareham

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

Fire stopping for commercial buildings in Fareham

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. The enquiries we see most involve openings found when ceilings come down for a refit and seals that don’t match their tested detail, on pipe penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors. Searching for sealant specialists in Fareham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

In a town like Fareham, penetration seals normally need attention after other trades have been through. Checking after M&E works is good practice, and we’ll seal what’s found where fire-rated sealant is the specified product.

Our workmanship is guaranteed for 12 months, in Fareham as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Cost factors for service penetrations

We price every job individually. The things that drive the figure:

  • How much existing material needs removing
  • Induction, permit and paperwork requirements
  • Which sealant the job calls for
  • Quantities, in metres or numbers

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Details that help us quote

A good diagnosis starts with the right details. Let us know:

  • What the building is and how it’s used
  • Approximate linear metres or a joint schedule
  • When you need the work done
  • The product your specification calls for

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Check with the data sheet before painting over fire sealant
  • Check risers and ceiling voids after each round of works
  • Get seals inspected before ceilings and boxing close
  • File the specified details where the next contractor can find them

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

What the job involves on each 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, and any outside it are raised with you.

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter.

Where services cross fire walls in Fareham

There are several hotels within about 2 miles of Fareham. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Fareham lies roughly 65 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.

Tenant changes at parks like Blackbrook Business Park (less than half a mile north-west of Fareham) bring new data and services, and openings through fire-resisting walls need the specified seal. Tenant changes at centres like Fareham Shopping Centre (to the east of Fareham) often mean new services through walls between units. Theatres, wards and plant rooms at sites like Knowle Hospital, 2 miles north of Fareham, all have compartment walls crossed by services.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Parking and loading for town-centre jobs in Fareham are worth mentioning when you send details. Industrial and business units usually have yard or car park space.

  1. We read the specification, drawings or penetration schedule you send.
  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. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Tell us what induction or permit system the site runs
  • Let building users know which areas are affected

Ask for a quote

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

Honest limits

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Reviewing a building’s overall fire safety
  • Construction that lacks the fire resistance the seal relies on

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

Joints and surfaces we work on

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

Your questions answered

Could you schedule work at a campus like Fareham College for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you work on a hospital site such as Knowle Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Can you reseal penetrations after our M&E works?

Yes. Send the schedule or marked-up drawings and the specified product details for a fixed quote. Work can run area by area behind the M&E trades.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Do you approve fire stopping for building control?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
