About our fire rated sealant in Whaddon

Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. We’re often asked to deal with fire seals that have cracked with movement and gaps around pipes and cables through fire-resisting walls, on pipe & cable gaps, service penetrations and plasterboard & masonry.

If you have holiday lets, a converted barn used for business or a community building near Whaddon, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Common problems we fix in Whaddon

Much fire stopping is hidden: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.

Signs it’s time to call us include:

  • Door frames with gaps between frame and wall
  • Seals cut through by electricians, plumbers or data installers
  • Fire seals that have cracked with movement
  • Linear gaps at the head of walls

Managing a site like Whaddon CofE First School? Then service openings in fire-resisting walls need checking after any refurbishment.

How to choose a mastic man

DIY versus a professional finish

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

Why act early in Whaddon

Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. Around Whaddon, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

What affects the cost of fire rated sealant

You will get a clear quote before we start. It takes into account:

  • Whether old sealant or filler has to be cut out
  • Any working-time requirements on site
  • How many areas need sealing
  • The size of the job

What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

Asking for a quote

Photos help, but a description is a good start. Please mention:

  • Where the property is
  • If someone has resealed it before
  • Any access issues, like height or stairs
  • Photos by email, if that is easy

Asking for a quote is easy: tell us what needs doing and where. A few photos by email make the job easier to understand, and we will come back to you with a quote.

What happens on the day

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Whaddon needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used.

How to prepare

  • Mention if the joints have been sealed before
  • Try not to wet indoor joints just before the visit
  • On commercial sites, let us know about site rules

Is intumescent sealant the same as fire-rated sealant?

An intumescent sealant expands when it gets hot to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

Is it messy?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Are you insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Is the work guaranteed?

Yes, always. There’s a 12-month guarantee on every job, large or small.

Do I have to be there?

Do you seal gaps around fire door frames?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door leaf and its hardware need a door specialist.

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Check risers, ceiling voids and cupboards during building checks
  • Allow for resealing whenever new services are run
  • Make resealing part of every contractor’s brief
  • Ask which product was used before you paint

File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes.

What fire rated sealant looks like in Whaddon

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.

If you let a flat or house near Milton Keynes Central station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking.
