Fire rated sealant in Wormley

We often work from an action list drawn up by a fire risk assessor on buildings across Wormley. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. We work on flats & HMOs, pipe & cable gaps and door frames, and people most often call us about gaps left after a refit or conversion and sealant items on a fire risk assessment action list.

Around a place like Wormley, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.

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

When to call us in Wormley

Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service isn’t always sealed again.

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

  • Gaps filled with a product that is not fire-rated
  • Gaps flagged on a fire risk assessment
  • Holes left by a change of layout
  • Gaps around pipes and cables through fire-resisting walls

For buildings such as Parish Church of St Lawrence, service openings in its walls need the right fire-rated sealant, as in any building.

What affects the cost of fire rated sealant

Some jobs are bigger than they look, and some smaller. The main factors:

  • Whether old sealant or filler has to be cut out
  • The number of rooms or windows
  • Working hours on commercial sites
  • Whether the work is at height

Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Helping us quote

Photos help, but a description is a good start. Try to tell us:

  • The problem you’ve noticed
  • Access, such as stairs, a lift or height
  • Roughly how big the job is
  • Whether it has been sealed before

To get a quote, phone 0345 464 0079 or email us and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.

Can I do it myself?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

What we do, step by step

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It usually takes anything from a few hours to several days, depending on how many gaps there are. A visit to Wormley is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  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. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. We record the locations and products used for your records.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Clear items away from the joints we’re working on
  • Mention any sign-in or site rules at work premises

How to get a quote

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

Related advice

Different surfaces, different methods

Door frames

Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details before the trim goes back.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment.

When it isn’t the sealant

We’ll always be straight with you, so here’s what new sealant will not do:

  • Problems with the door itself rather than the gap around the frame
  • Large holes that need a different fire-stopping system
  • Construction that doesn’t provide fire resistance on its own

If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

Surfaces we seal

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

Yes. Wormley is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is intumescent sealant the same as fire-rated sealant?

An intumescent sealant expands when it gets hot. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.

Do you seal gaps around fire door frames?

Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.

How long will you be here?

As a guide, most jobs take from a few hours to a few days, depending on the number of gaps and the access. Larger jobs naturally take longer.
