About our fire rated sealant in Slinfold

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. We work on pipe & cable gaps, door frames and linear gaps, and the jobs we see most are damaged fire sealant left by other trades and open gaps behind door architraves.

For a small place like Slinfold, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.

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

What affects the cost of fire rated sealant

You’ll get a clear quote before any work starts. It takes into account:

  • Whether the work is at height
  • The number of rooms or windows
  • Working hours on commercial sites
  • The amount of work

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. Call for a quick quote and we will go through it with you.

What we need to know

Photos by email are helpful but not essential. Please mention:

  • What’s wrong with the joints now
  • Where the job is, and your postcode
  • Whether it’s a home or a business
  • If someone has resealed it before

We quote each job on its own. Just ring 0345 464 0079 or drop us an email with the details.

How the visit works

Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Slinfold, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • Mention any tricky access
  • Let us know about earlier repairs to the joints
  • For business premises, tell us about site rules or sign-in

Related advice

Should I try it myself first?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Common questions in Slinfold

Do you work for hotels and guest houses in Slinfold?

Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

I let a flat near Christs Hospital station. Can you help?

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

Is intumescent sealant the same as fire-rated sealant?

An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all and which one is used depends on the job.

Can I do it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

How do I get a quote for fire rated sealant in Slinfold?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done.

What should I tell you?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or send us an email.

Will you assess my building’s fire safety?

No. We follow the requirements from your assessor, designer or building control, and apply each product to its tested details.

How the job changes by surface

Door frames

A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it.

Landlord and commercial work in Slinfold

We also work for property managers and facilities teams in Slinfold and across West Sussex. Several sites can be quoted together, and we are fully insured.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Commercial buildings in Slinfold

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 work to the specification you’re given, installing the product to its tested details. There are hotels and other places to stay in and around Slinfold. Hotel work can be planned room by room, with out-of-hours working where needed.

Community buildings like The Parish Church of St Peter are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as Slinfold CofE Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

Signs you need fire rated sealant in Slinfold

Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.

Most people get in touch after spotting one of these:

  • Damaged fire sealant left by other trades
  • Fire seals that have cracked with movement
  • Door frames with gaps between frame and wall
  • New service routes left unsealed after building work

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

10 questions to ask before booking

How to look after the new joints

After the cure time, these simple habits help:

  • Keep the record of products and locations with your fire safety documents
  • Ask which product was used before you paint
  • Photograph sealed gaps before they’re covered up
  • Get damaged fire seals looked at promptly

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
