Fire stopping for Wavendon sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Surface by surface

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, with backing added if the detail requires it.

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance, including keys, permits and any isolations.

Fire stopping in Wavendon

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you are dealing with fire stopping installed outside its tested range and fire seals cut back for extra cables and never reinstated, we can put it right, whatever the surface. Searching for sealant specialists in Wavendon? We have been sealing commercial buildings since 2005.

Barn and farm-building conversions near places like Wavendon often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Wavendon can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Make sure the joints can be reached
  • Let building users know which areas are affected
  • Have the specification and drawings to hand

Advice

Wavendon: questions and answers

Could you schedule work at a campus like The Open University for the vacation?

Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you work in occupied care homes around Wavendon?

Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Do you cover Wavendon?

Yes. Sites across Wavendon are covered, and the same phone number covers every area.

What does an EI 60 rating mean?

In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

How many days will you need on site?

It depends on the scope, but the work usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we’ll set out a timescale with the quote.

What we’re called out for in Wavendon

Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access normally bring them to light.

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

  • Service penetrations left open after M&E works
  • Unsealed joints where partitions meet the slab
  • Builders’ foam or ordinary silicone in compartment walls
  • Fire sealant pulled out of the opening

Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Questions to ask before you book

  • Are they CHAS accredited or on Constructionline?
  • What level of public liability insurance do they hold?
  • How long is the guarantee, and what does it include?
  • Whether their applicators hold CSCS cards

Choosing a commercial sealant contractor

General trades versus a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

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.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Share these points with them:

  • Flag new cables with no seal around them
  • Put resealing into every M&E and fit-out package
  • Keep product data and details in the fire safety file
  • Don’t let anyone top up a fire seal with the wrong product

New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

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