How we handle fire rated sealant in Runfold

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We work on linear gaps, pipe & cable gaps and plasterboard & masonry, and common reasons people get in touch are seals cut through by electricians, plumbers or data installers and standard silicone or caulk in a fire-stopping gap.

For a small place like Runfold, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

You get a one-year guarantee, the same in Runfold as everywhere else we work.

Runfold questions

Is Runfold within the area you cover?

Yes. Runfold is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you work for landlords with property near Farnham station?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.

How long will you be here?

That depends on the amount of work, but as a guide it takes from a few hours to a few days, depending on the number of gaps and the access. We’ll tell you when we quote.

Can you tell me how many minutes the seal will last?

Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.

Is there a guarantee?

Yes. Each job is guaranteed for twelve months, large or small.

How do I get a quote for fire rated sealant in Runfold?

It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or send us an email with a short description of the job.

What sealant do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Do I need to be at home?

It depends on the job. For work indoors, someone needs to let us in.

What sealant work cannot fix

It helps to know what we cannot do:

  • Construction that doesn’t provide fire resistance on its own
  • Issuing a fire rating or certificate for a building
  • Deciding what fire stopping a building needs

If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

What we seal

  • Plasterboard & masonry
  • Door frames
  • Pipe & cable gaps
  • Linear gaps
  • Service penetrations
  • Flats & HMOs

What happens if it’s left?

An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Older cottages and farmhouses around Runfold can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

What you get with us

  • Old sealant always removed completely
  • We are fully insured
  • More than 20 years in sealant work

What fire rated sealant looks like in Runfold

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.

For landlords with property near Farnham station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For site and facilities teams at buildings such as South Farnham School, gaps opened by contractors for new cabling are a common finding in schools and offices.

How the visit works

We keep the work tidy and contained to the joints we’re treating. Expect the work to take from a few hours to a few days, depending on the number of gaps and the access, and we tell you how long to leave it before we go. Somewhere as small as Runfold, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. We record the locations and products used for your records.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks
  • Plan for the work area to be out of bounds to pets and children
  • Clear the area around the work

Looking after it afterwards

Aftercare is simple:

  • Report cracked or damaged seals as soon as you notice them
  • Tell trades working in the building that fire seals must be put back
  • Check whether a sealant can be painted before decorating over it
  • Include hidden areas like risers in routine checks

Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

How we quote for fire rated sealant

Jobs vary more than people expect. What affects the quote:

  • Which sealant suits the joint
  • Any mould that needs treating
  • How much there is to do
  • Whether the work is at height

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

Asking for a quote

To help us quote quickly, please include:

  • Pictures of the joints, sent by email
  • Any access issues, like height or stairs
  • Whether it has been sealed before
  • The type of property

For a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. You’ll have a clear quote before we start.

Common problems we fix in Runfold

Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.

People usually contact us after spotting one of these:

  • Gaps flagged on a fire risk assessment
  • Holes left by a change of layout
  • Cracked or shrunken fire-rated sealant
  • Gaps where walls meet ceilings or slabs

For buildings such as The Church of the Good Shepherd, gaps around pipes and cables are worth checking after any building work there.

Work for landlords, hotels and businesses

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
