Fire rated sealant in Penn, done properly

We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on plasterboard & masonry, flats & HMOs and pipe & cable gaps, and common reasons people get in touch are gaps flagged on a fire risk assessment and open joints along the top of partitions.

For holiday lets, converted business premises or a community building near Penn, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

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

Why deal with it now?

Paying for fire stopping that has to be redone is a false economy. Work that does not follow the tested detail may have to come out again when the building is next checked. Where a wall is exposed, as many are in small places like Penn, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Do you need fire rated sealant in Penn?

Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.

Any of these means the joints need attention:

  • Gaps flagged on a fire risk assessment
  • Ordinary sealant used where a fire-rated product was needed
  • Open joints along the top of partitions
  • Unsealed gaps where pipes and cables go through a wall

Rented homes near High Wycombe station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

How to choose a mastic man

Surface by surface

Flats and HMOs

Conversions normally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product.

Masonry and concrete

Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point against the product’s tested range.

The process

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Penn, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  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. Every location is recorded with the product used for your records.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • On commercial sites, let us know about site rules
  • Tell us about any water getting in

When it isn’t the sealant

Some problems need a builder, plumber or other trade rather than us:

  • Construction that does not provide fire resistance on its own
  • Large holes that need a different fire-stopping system
  • Doors that aren’t fire doors in the first place

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

Fire rated sealant around Penn

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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Managing a site like Tylers Green First School? Then fire-stopping around service openings should be restored whenever new services go in. For buildings such as Church of St Margaret, gaps around pipes and cables are worth checking after any building work there.

Landlord and commercial work in Penn

Housing providers, facilities teams and property managers book us too in Penn and across Buckinghamshire. Several sites can be quoted together.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

Can I do it myself?

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 does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Yes. You get a list of where we worked and what we used for your files.

Do you certify the fire stopping?

Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.
