Fire rated sealant near Cackle Street

Fire rated sealant for homes and businesses in Cackle Street

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. If you are dealing with linear gaps at the head of walls and old fire sealant that has split or come away, we can help.

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

We stand behind the work with a 12-month guarantee.

What we do, step by step

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In a small place like Cackle Street, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your records.

How to prepare

  • Clear items away from the joints we’re working on
  • Let us know about earlier repairs to the joints
  • Mention any sign-in or site rules at work premises

Surface by surface

Flats and HMOs

Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and record where they are.

Door frames

Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size.

Fire rated sealant in Cackle Street: local notes

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, and gaps around services are often picked up there. 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 Brede Primary School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like The Parish Church of St George are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Aftercare tips

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Check whether a sealant can be painted before decorating over it
  • Check risers, ceiling voids and cupboards during building checks
  • Flag any open gap you spot round a pipe or cable
  • Ask every contractor to reseal any fire stopping they disturb

Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

Common problems we fix in Cackle Street

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

If you can see any of these, it’s time to have the joints looked at:

  • Open holes round services passing through fire walls
  • Ordinary sealant used where a fire-rated product was needed
  • New service routes left unsealed after building work
  • Gaps flagged on a fire risk assessment

Rented homes near Doleham station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

Before you book anyone

  • Whether you can choose the colour
  • When the joint can take water or movement
  • Whether all the old sealant comes out first
  • How much experience the applicator has

How we quote for fire rated sealant

Your quote is based on your job. We take into account:

  • Access and height
  • How many areas need sealing
  • Whether there’s mould to deal with
  • How much there is to do

The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.

Helping us quote

When you call or email, these details help:

  • The address or postcode of the job
  • A few pictures by email, if you can
  • Roughly how big the job is
  • The type of property

Call for a quick quote, or email us if that is easier. Describe what needs sealing and we will explain what’s involved before giving you a price.

Should I try it myself first?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
