Fire rated sealant for Weston Underwood homes and businesses

Fire rated sealant in Weston Underwood, done properly

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate. Typical jobs include seals cut through by electricians, plumbers or data installers and open joints along the top of partitions, on plasterboard & masonry, linear gaps and door frames.

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

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Quotes for fire rated sealant in Weston Underwood

Your quote is based on your job. We look at:

  • The size of the job
  • How many areas need sealing
  • The old material and how stubborn it is
  • Access and height

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email.

Helping us quote

Photos by email are helpful but not essential. Try to tell us:

  • Pictures of the joints, sent by email
  • If someone has resealed it before
  • The problem you’ve noticed
  • The address or postcode of the job

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.

When it is not the sealant

To be straight with you, 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
  • Fire doors that need new seals, closers or hardware

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

Surfaces we seal

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

How it works

Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Weston Underwood, 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. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  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.

How to prepare

  • Clear the area around the work
  • Let us know about earlier repairs to the joints
  • For business premises, tell us about site rules or sign-in

Related advice

Leave it or put it right?

For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we will tell you. Where a wall is exposed, as many are in small places like Weston Underwood, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Why us?

  • Any old sealant cut out fully, not covered over
  • Tidy, careful work
  • Over 20 years’ experience
  • One-year guarantee on every job

Surface by surface

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length so there are no open sections left.

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.

Fire rated sealant in Weston Underwood: local notes

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.

Community buildings like Church of St Lawrence are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Aftercare tips

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

  • Keep photos of seals that will be hidden
  • Store the list of sealed gaps with your building paperwork
  • Get damaged fire seals looked at promptly
  • Ask which product was used before you paint

File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.

Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.

What we’re called out for in Weston Underwood

A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.

Keep an eye out for these signs:

  • Gaps left after a refit or conversion
  • Unsealed gaps around fire door frames
  • Open joints along the top of partitions
  • Damaged fire sealant left by other trades

Schools such as Olney Infant Academy are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.
