Trusted fire rated sealant in Lunsford's Cross

How we handle fire rated sealant in Lunsford's Cross

A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over. If you have standard silicone or caulk in a fire-stopping gap and gaps around pipes and cables through fire-resisting walls, we can help, on plasterboard & masonry, flats & HMOs and linear gaps alike.

For holiday lets, converted business premises or a community building near Lunsford's Cross, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

A 12-month guarantee comes with the work, just as it does everywhere we cover.

Should I try it myself first?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

Surface by surface

Masonry and concrete

Holes through concrete and block are rarely neat. We check the gap size around the service to make sure it suits the product.

Flats and HMOs

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

Commercial buildings in Lunsford's Cross

For seaside hotels, guest houses and holiday lets around Lunsford's Cross, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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 are given, installing the product to its tested details.

For site and facilities teams at buildings such as Ninfield Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

When to call us in Lunsford's Cross

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

Look out for any of the following:

  • Fire stopping disturbed by later work
  • Open gaps behind door architraves
  • Holes left by a change of layout
  • Gaps filled with a product that is not fire-rated

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

Questions to ask before you book

  • What happens if they find a problem under the old sealant
  • Whether they’re fully insured
  • Which colour the sealant will be
  • Who does the work, and how experienced they are

Choosing a sealant specialist

What sealant work can’t fix

New sealant can’t fix everything, and we will tell you before work begins. Sealant will not put right:

  • Fire risk assessments, which need a qualified assessor
  • Sign-off of the building, which sits with building control or your assessor
  • Walls or floors that weren’t built to resist fire

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

Joints and surfaces we work on

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

What affects the cost of fire rated sealant

Every job gets its own quote. These are the things that affect it:

  • Access and height
  • How many areas need sealing
  • Working hours on commercial sites
  • How much old sealant there is and how hard it is to remove

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

What to tell us for a quote

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

  • How we’d reach the joints
  • How many joints, rooms or windows are involved
  • What’s wrong with the joints now
  • Where the job is, and your postcode

We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or send us an email and describe the job, and photos are welcome.

Why deal with it now?

If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up means you can show the action was taken. Where a wall is exposed, as many are in small places like Lunsford's Cross, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Why us?

  • We’re fully insured
  • Homes, businesses and hotels
  • Any old sealant cut out fully, not covered over
  • 180+ five-star Google reviews

Can I add another job to the visit?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

What happens on the day

There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes from a few hours to a few days, depending on the number of gaps and the access, including the tidy-up. In a small place like Lunsford's Cross, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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.

Getting ready for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about any previous sealing or DIY attempts
  • Let us know about stairs, lifts or work at height
