Fire rated sealant in South Leigh, done properly

Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. We work on door frames, plasterboard & masonry and flats & HMOs, and the jobs we see most are joints picked up in a fire-stopping survey and unsealed gaps where pipes and cables go through a wall.

If you have holiday lets, a converted barn used for business or a community building near South Leigh, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

A one-year guarantee comes as standard.

Fire rated sealant around South Leigh

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 work to the specification you’re given, installing the product to its tested details.

If you look after a church, hall or community building such as Church of St James, older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Hanborough station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

DIY versus a professional finish

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

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 does not work out, we can still put it right.

FAQs for South Leigh

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

Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.

Do you cover South Leigh for fire rated sealant?

Yes, South Leigh is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.

What information do you need?

Let us know what needs doing and where. We will ask anything else we need to know.

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

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.

Do you do fire sealant around door frames?

Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.

How long will you be here?

As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Larger jobs naturally take longer, and we’ll tell you how long to expect.

Can I use normal mastic around a pipe through a fire wall?

No. Standard sealants are not made or tested to stop fire. If it’s been used, we remove it and use the right product.

Leave it or put it right?

Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Around South Leigh, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

What you get with us

  • We are fully insured
  • We leave the area clean and tidy
  • Approved under the ARBOMaster scheme
  • Any old sealant cut out fully, not covered over

How it works

The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours for a handful of gaps, and longer for a whole building, and we tell you how long to leave it before we go. Somewhere as small as South Leigh, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about earlier repairs to the joints

Advice

What we’re called out for in South Leigh

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.

People generally contact us after spotting something like this:

  • Door frames with gaps between frame and wall
  • Gaps left after a refit or conversion
  • Gaps flagged on a fire risk assessment
  • Unsealed gaps where pipes and cables go through a wall

For site and facilities teams at buildings such as Wood Green School, service openings in fire-resisting walls need checking after any refurbishment.

What to look for in a quote

  • What insurance they hold
  • What the cure time is

Choosing a sealant specialist

What affects the cost of fire rated sealant

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

  • Working hours on commercial sites
  • Whether old sealant or filler has to be cut out
  • Mould in or behind the old joints
  • How many areas need sealing

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

What to tell us for a quote

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

  • The type of property
  • What’s wrong with the joints now
  • Access, such as stairs, a lift or height
  • Roughly how big the job is

For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we will explain what’s involved.

What we can’t put right

It helps to know what we cannot do too:

  • Sign-off of the building, which sits with building control or your assessor
  • Fire risk assessments, which need a qualified assessor
  • Doors that aren’t fire doors in the first place

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

Surfaces we seal

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

Work for landlords, hotels and businesses

We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

For anyone letting property in or around South Leigh, several properties can go on one quote. Just tell us the addresses and what each one needs.
