Fire rated sealant in Stony Green, done properly

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on linear gaps, plasterboard & masonry and flats & HMOs, and common reasons people get in touch are fire seals that have cracked with movement and damaged fire sealant left by other trades.

For a small place like Stony Green, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

Each job carries a 12-month guarantee, whatever its size.

What happens if it’s left?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Stony Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Fire rated sealant around Stony Green

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Rented homes near Great Missenden station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Prestwood Junior School, fire-stopping around service openings should be restored whenever new services go in.

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you’re 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.

Do you need fire rated sealant in Stony Green?

Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.

Keep an eye out for any of the following:

  • Fire seals that have cracked with movement
  • Unsealed gaps where pipes and cables go through a wall
  • Gaps where walls meet ceilings or slabs
  • New service routes left unsealed after building work

For buildings such as Holy Trinity Church, service openings in its walls need the right fire-rated sealant, as in any building.

10 questions to ask before booking

The process

There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Stony 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. Old, damaged or unsuitable sealant is removed.
  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. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • Clear items away from the joints we are working on
  • Tell us if parking is tricky

Is Stony Green within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Do you remove the old sealant?

Yes. We cut out all the old sealant and clean the joint.

How we quote for fire rated sealant

There’s no set price list, because jobs vary so much. What we look at:

  • Whether there’s mould to deal with
  • How easy the joints are to reach
  • The size of the job
  • How many rooms, windows or areas are involved

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

What we need to know

When you call or email, these details help:

  • What’s wrong with the joints now
  • Pictures of the joints, sent by email
  • The type of property
  • Access, such as stairs, a lift or height

If you’re in Stony Green and need fire rated sealant, phone 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and you will get a clear quote before work begins.

Aftercare tips

How long the joints last depends on use and care. Here’s what we suggest:

  • Report cracked or damaged seals as soon as you notice them
  • Check risers, ceiling voids and cupboards during building checks
  • Take pictures of fire stopping before ceilings or boxing go back
  • Include fire stopping when you schedule refits

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
