Fire rated sealant near Durley

What the job involves on each surface

Linear gaps

A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.

Aftercare tips

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

  • Allow for resealing whenever new services are run
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Tell trades working in the building that fire seals must be put back
  • Keep pictures of seals that will be hidden

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.

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.

What we’re called out for in Durley

Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.

People usually contact us after spotting one of these:

  • Standard silicone or caulk in a fire-stopping gap
  • Door frames with gaps between frame and wall
  • New service routes left unsealed after building work
  • Linear gaps at the head of walls

Community buildings like Church of the Holy Cross are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Choosing a sealant specialist

Durley questions

Do you cover Durley for fire rated sealant?

Yes, Durley is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.

Will you come out to Durley?

Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you match the sealant colour?

We help you choose a colour that suits. The choice depends on the product the joint needs.

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

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.

What fire rating will the seal have?

Ratings and certificates aren’t something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.

Is it worth trying it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Can ordinary silicone be used in a fire-stopping gap?

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

Will there be a smell?

Possibly a little. It fades as the sealant cures.

How we quote for fire rated sealant

There’s no set price list. What we look at:

  • Working hours on commercial sites
  • The type of sealant required
  • Mould in or behind the old joints
  • The number of rooms or windows

The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

Helping us quote

Before you ask for a quote, have a think about:

  • Whether it’s a home or a business
  • What’s wrong with the joints now
  • Any access issues, like height or stairs
  • Pictures of the joints, sent by email

Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job.

Fire rated sealant around Durley

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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 Durley Church of England Controlled Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Letting a property close to Hedge End station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

What sealant work can’t fix

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Fire doors that need new seals, closers or hardware
  • Issuing a fire rating or certificate for a building
  • Fire risk assessments, which need a qualified assessor

If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before booking.

Surfaces we seal

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

Work for landlords, hotels and businesses

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.

The process

On the day, we look over the joints with you first. We protect the surfaces around the joints before any work starts. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Durley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. We put in whatever backing or fill the product detail specifies.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Before we arrive

  • Keep pets and children clear of the area while we work
  • Mention any sign-in or site rules at work premises
  • Move anything stored near the joints
