Fire rated sealant for homes and businesses in Upper Basildon

Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. We are often asked to deal with open gaps behind door architraves and gaps filled with a product that isn’t fire-rated, across door frames, pipe & cable gaps and flats & HMOs.

If you have holiday lets, a converted barn used for business or a community building near Upper Basildon, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

There’s a 12-month guarantee on every job, whatever its size.

When it isn’t the sealant

In fairness, there are a few things sealant will not fix:

  • Walls or floors that weren’t built to resist fire
  • Assessing a building’s fire safety
  • Sign-off of the building, which sits with building control or your assessor

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

Surfaces we seal

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

What fire rated sealant looks like in Upper Basildon

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 work to the specification you are given, installing the product to its tested details.

Schools such as Basildon C.E. Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like St Stephen's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Why deal with it now?

A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Where a wall is exposed, as many are in small places like Upper Basildon, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

What you get with us

  • We leave the area clean and tidy
  • Full insurance on every job
  • Any old sealant cut out fully, not covered over
  • Sanitary silicone with an anti-fungal additive in wet areas

How the visit works

Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Upper Basildon, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

Getting ready for the visit

  • Keep pets and children clear of the area while we work
  • Let us know about earlier repairs to the joints
  • On commercial sites, let us know about site rules

When to call us in Upper Basildon

Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.

The most common problems we see are:

  • Sealant items on a fire risk assessment action list
  • Open holes round services passing through fire walls
  • Gaps where walls meet ceilings or slabs
  • Door frames with gaps between frame and wall

Letting a property close to Pangbourne station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
