Fire rated sealant in Reading: how it works

We do not assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on linear gaps, service penetrations and pipe & cable gaps, and the jobs we see most are standard silicone or caulk in a fire-stopping gap and open joints along the top of partitions.

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

How we quote

Commercial buildings across Reading

From Caversham, Norcot and West Reading to its smaller places, Reading has workplaces, hotels and schools with joints to look after.

London and the South East are among the drier parts of the UK, though outside sealant still needs a dry, clean joint, so work across Reading is planned around the weather.

Caversham: If you look after a church, hall or community building such as Grace Church, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like The Hill Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Keeping the joints in good condition

Good habits help new joints last longer. Our tips:

  • Ask which product was used before you paint
  • Ask every contractor to reseal any fire stopping they disturb
  • File the fire-stopping record where your assessor can find it
  • Photograph sealed gaps before they’re covered up

Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. Ask us if you’re not sure which product was used.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the list grows.

What affects the quote in Reading

Every job gets its own quote. This is what makes a difference:

  • The type of sealant required
  • How easy the joints are to reach
  • Whether old sealant or filler has to be cut out
  • Working hours on commercial sites

Combining jobs into one visit is generally more efficient than separate visits. We’ll send you a clear quote for the lot.

What we need to know

Photos help, but a description is a good start. Please mention:

  • Photos by email, if that’s easy
  • Where the job is, and your postcode
  • What the problem is, such as mould, gaps, leaks or cracking
  • Whether it has been sealed before

Every job is quoted individually, so start by telling us what you need. Just ring 0345 464 0079 or email us with the details.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Honest limits

Sealant is not the answer to every problem, and we will tell you before we start. Sealant will not put right:

  • Doors that aren’t fire doors in the first place
  • A wall that is not a fire-resisting element to begin with
  • Issuing a fire rating or certificate for a building

Why it fails

Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole they leave doesn’t always get resealed.

Any of these means the joints need attention:

  • Fire stopping disturbed by later work
  • Old fire sealant that has split or come away
  • Open gaps behind door architraves
  • Unsealed gaps where pipes and cables go through a wall

Common questions in Reading

Can you fill the gap behind a fire door frame?

Yes. The joint between frame and wall is sealed with a fire-rated sealant following the tested details. The door leaf and its hardware need a door specialist.

Is it OK to seal over old sealant?

No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.

Can you match the sealant colour?

In most cases you can choose. We will explain which colours are available and agree one before we start.

Do the sealants smell?

Sometimes, a little. Any smell clears as the sealant cures.

Is standard sealant good enough for a fire gap?

No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.

What fire rating will the seal have?

We do not issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.
