Fire stopping in Godmersham, done properly

Facilities managers in Godmersham often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you are dealing with service penetrations left open after M&E works and fire-rated sealant that has cracked or shrunk back, we can help, whatever the surface. Searching for sealant specialists in Godmersham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Smaller places such as Godmersham 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.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Signs you need fire stopping in Godmersham

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps. The tested detail for a linear joint states the width and movement it covers.

Common reasons buildings call us in:

  • Damaged fire seals in risers and voids
  • Head-of-wall gaps with no fire seal
  • Service penetrations left open after M&E works
  • Old intumescent sealant that has split away

For a hospital such as William Harvey Hospital, which lies south of Godmersham, penetration sealing is usually phased ward by ward, with infection-control rules agreed first.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • Their approach to joint depth and backing
  • Which product they’ll use, and why it suits the joint
  • Whether primer will be used where the manufacturer specifies it

How to choose a sealant contractor

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • Construction that lacks the fire resistance the seal relies on
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Signing off or certifying a building’s fire stopping

If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think.

What we seal

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

Looking after the joints

Problems stay small when the joints are checked regularly. Specifically:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Keep general-purpose fillers away from compartment walls
  • Flag new cables with no seal around them
  • Get seals inspected before ceilings and boxing close

Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.

Quoting for work in Godmersham

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Travel to remote or island sites
  • How much existing material needs removing
  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Any dates the work must fit around
  • Drawings or a marked-up plan, if available
  • The product your specification calls for
  • The type of building and who uses it

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or use the quote form.

Fire stopping around Godmersham: what changes locally

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Central London is about 50 miles from Godmersham. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

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

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Godmersham are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Let building users know which areas are affected
  • Point out parking and an unloading spot
