Fire rated sealant for Liss Forest homes and businesses

Fire rated sealant for homes and businesses in Liss Forest

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. If you have door frames with gaps between frame and wall and gaps filled with a product that isn’t fire-rated, we can put it right.

In a village or hamlet like Liss Forest, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

You get a one-year guarantee, the same in Liss Forest as everywhere else we work.

FAQs for Liss Forest

Do you cover Liss Forest for fire rated sealant?

Yes, Liss Forest 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 tell us what needs doing, and we will send you a clear quote.

I’m a tenant. Can you help?

Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.

Is it messy?

Tidy work is part of the job. We protect what’s around the joints.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

What sealant do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.

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

No. It might close the gap, but it is not a fire-rated seal. Use a product tested for that gap and service, or ask us to do it.

Can you fill the gap behind a fire door frame?

Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.

When to call us in Liss Forest

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It looks sealed, but it isn’t fire-rated.

The most common problems we see are:

  • Fire stopping disturbed by later work
  • Unsealed gaps around fire door frames
  • Gaps flagged on a fire risk assessment
  • Holes left by a change of layout

Managing a site like Liss Infant School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

10 questions to ask before you book

Landlord and commercial work in Liss Forest

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

What we do, step by step

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on how many gaps there are and we leave things clean and tidy. In a small place like Liss Forest, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your records.

Preparing for the visit

  • Mention any parking rules near the property
  • Clear the area around the work
  • For indoor joints, keep the area dry beforehand if you can

Honest limits

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • Big openings where sealant alone isn’t the tested solution
  • Fire risk assessments, which need a qualified assessor
  • Construction that does not provide fire resistance on its own

If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Where we work in Liss Forest

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

Why deal with it now?

Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Older cottages and farmhouses around Liss Forest can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

Keeping the joints in good condition

Aftercare is simple:

  • Tell trades working in the building that fire seals must be put back
  • File the fire-stopping record where your assessor can find it
  • Check whether a sealant can be painted before decorating over it
  • Look in service cupboards and ceiling voids from time to time

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

Commercial buildings in Liss Forest

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, 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.

For buildings such as St Saviour's, gaps around pipes and cables are worth checking after any building work there. For landlords with property near Liss station, any gap left by new services in shared walls should be closed with a fire-rated product.

How the job changes by surface

Door frames

Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details before the trim goes back.

Linear gaps

A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both.
