Fire rated sealant near Horsleys Green

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Keep the record of products and locations with your fire safety documents
  • Allow for resealing whenever new services are run
  • Include hidden areas like risers in routine checks
  • Tell trades working in the building that fire seals must be put back

Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.

An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

How we handle fire rated sealant in Horsleys Green

We often work from an action list drawn up by a fire risk assessor for buildings in Horsleys Green. If you share the list, we can quote for the gaps that need fire-rated sealant. If you have linear gaps at the head of walls and gaps flagged on a fire risk assessment, we can put it right.

Somewhere as small as Horsleys Green, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

Our work is backed for twelve months, in Horsleys Green and everywhere else we cover.

Fire rated sealant in Horsleys Green: 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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

How it works

Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours for a handful of gaps, and longer for a whole building, depending on how much there is to do. Somewhere as small as Horsleys Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about parking restrictions
  • Keep pets and children clear of the area while we work

Landlord and commercial work in Horsleys Green

We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Different surfaces, different methods

Door frames

A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

DIY sealant or a professional job?

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

What we are called out for in Horsleys Green

Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.

People normally contact us after spotting something like this:

  • Old fire sealant that has split or come away
  • Gaps filled with a product that isn’t fire-rated
  • Sealant items on a fire risk assessment action list
  • Open gaps behind door architraves

If you look after a building such as The Mary Towerton School At Studley Green, service openings in fire-resisting walls need checking after any refurbishment.

Before booking anyone

  • Whether you can choose the colour
  • Whether they’re fully insured
  • Which sealant they’ll use, and why
  • When the joint can take water or movement

FAQs for Horsleys Green

Can you help a landlord with a rental near Saunderton station?

Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.

Do you cover Horsleys Green for fire rated sealant?

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

What sealant do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Is there any odour?

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

Can you fill the gap behind a fire door frame?

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

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.

Does someone need to be in?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Do you carry out fire risk assessments?

No. That’s for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.

Honest limits

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • Large holes that need a different fire-stopping system
  • Assessing a building’s fire safety
  • Walls or floors that weren’t built to resist fire

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