About our fire rated sealant in Newbury

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. We’re often asked to deal with ordinary sealant used where a fire-rated product was needed and unsealed gaps where pipes and cables go through a wall, across plasterboard & masonry, linear gaps and service penetrations.

If you look after a school, care home, pub or office in Newbury, washroom sealant, kitchen joints and fire-rated sealant around service openings all need upkeep. Work can be planned around opening hours where needed.

Your job is guaranteed for a year, as with all our work.

When to call us in Newbury

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

People normally contact us after spotting something like this:

  • Holes left by a change of layout
  • Gaps around pipes and cables through fire-resisting walls
  • Open gaps behind door architraves
  • Open joints along the top of partitions

Letting a property close to Newbury station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Choosing a sealant specialist

Workplaces and buildings in Newbury

There are hotels and other places to stay in and around Newbury. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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 work to the specification you’re given, installing the product to its tested details.

Community buildings like St Nicolas Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as St Nicolas C.E. Junior School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

FAQs for Newbury

Is Newbury in your area for fire rated sealant?

Yes, Newbury is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.

Do you work for hotels and guest houses in Newbury?

Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.

Can I use normal mastic around a pipe through a fire wall?

No. It looks sealed but will not perform as fire stopping. Use a product tested for that gap and service, or ask us to do it.

Is intumescent sealant the same as fire-rated sealant?

Intumescent means it swells when heated, helping close the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.

Is there a guarantee?

Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.

Where are you based?

We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before resealing.

Is it worth trying it myself?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

Aftercare tips

So the new joints stay in good condition:

  • Keep the record of products and locations with your fire safety documents
  • Ask which product was used before you paint
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Flag any open gap you spot round a pipe or cable

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot, so ask us which we used.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded so you can show it was dealt with.

What affects the cost of fire rated sealant

We quote each job individually. This is what makes a difference:

  • The product the joint needs
  • How many areas need sealing
  • Whether the work is at height
  • Any mould that needs treating

The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

What to tell us for a quote

To help us quote quickly, please include:

  • Pictures of the joints, sent by email
  • Any previous sealing or DIY work
  • Roughly how big the job is
  • What the problem is, such as mould, gaps, leaks or cracking

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.

What the job involves on each surface

Door frames

We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist.

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.

What we do, step by step

A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes anything from a few hours to several days, depending on how many gaps there are. A visit in Newbury needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  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. We hand over a list of locations and products.

How to prepare

  • Mention if the joints have been sealed before
  • Let us know about stairs, lifts or work at height
  • For business premises, tell us about site rules or sign-in

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

Honest limits

To be straight with you, some problems need a different trade:

  • Sign-off of the building, which sits with building control or your assessor
  • Fire doors that need new seals, closers or hardware
  • Fire risk assessments, which need a qualified assessor

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.

Joints and surfaces we work on

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