Fire rated sealant in Addlestone

For landlords and businesses

In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

Landlords and agents in Addlestone can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

Fire rated sealant in Addlestone, done properly

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. Common call-outs are for door frames with gaps between frame and wall and gaps around pipes and cables through fire-resisting walls, across door frames, service penetrations and plasterboard & masonry.

Around a place like Addlestone, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.

Big or small, you get the same 12-month guarantee in Addlestone and across Surrey.

Addlestone: your questions answered

Will you come out to Addlestone?

Yes. Addlestone is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you work for landlords with property near Addlestone station?

Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.

Do you remove the old sealant?

Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

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

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.

Is standard sealant good enough for a fire gap?

No. It might close the gap, but it isn’t a fire-rated seal. A tested fire-rated product is needed, or ask us to do it.

Where are you based?

Our base is Crawley. Our area covers South East England, London and Scotland.

Do you carry out fire risk assessments?

No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.

Are you ARBOMaster approved?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

What happens if it’s left?

Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. In an older home around Addlestone, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Why book with us

  • We’re fully insured
  • Quality sealants from Arbo and Everbuild
  • Any old sealant cut out fully, not covered over
  • Anti-fungal silicone where joints get wet

Should I try it myself first?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

How to look after the new joints

Aftercare is simple, and it makes a real difference:

  • Make resealing part of every contractor’s brief
  • Don’t paint over fire sealant until it has cured
  • Include fire stopping when you schedule refits
  • Keep general-purpose foam and caulk away from fire-stopping gaps

Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.

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

Fire rated sealant around Addlestone

Addlestone has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

If you look after a building such as Darley Dene Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Rented homes near Addlestone station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Do you need fire rated sealant in Addlestone?

Much fire stopping is hidden: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

Common reasons people contact us are:

  • Gaps flagged on a fire risk assessment
  • Damaged fire sealant left by other trades
  • Fire seals that have cracked with movement
  • Open joints along the top of partitions

If you look after a church, hall or community building such as St Paul's, older buildings that have had new heating or wiring often have service gaps worth checking.

What we do, step by step

We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. The job usually takes from a few hours to a few days, depending on the number of gaps and the access, and we explain the cure time before we leave.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed and the gap cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products.

Getting ready for the visit

  • Let us know about stairs, lifts or work at height

What the job involves on each surface

Plasterboard walls

Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard for the gap we’re sealing.

Linear gaps

Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.
