Fire rated sealant in Crays Hill

Bigger jobs can be worked through in stages, flat by flat or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. We work on linear gaps, door frames and pipe & cable gaps, and common reasons people get in touch are cracked or shrunken fire-rated sealant and new service routes left unsealed after building work.

For a small place like Crays Hill, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

All of our work is guaranteed for twelve months, in Crays Hill and everywhere else we cover.

How to look after the new joints

Simple care keeps the joints in good condition. We recommend:

  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Check risers, ceiling voids and cupboards during building checks
  • Photograph sealed gaps before they’re covered up
  • Do not paint over fire sealant until it has cured

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t and we’ll tell you which one you have.

Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Should I try it myself first?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What we do, step by step

At the end, we look at the finished work together. The visit itself generally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the amount of work. Somewhere like Crays Hill needs a little journey planning: let us know about lanes, gates and parking. 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. We hand over a list of locations and products for your records.

Before we arrive

  • Tell us about any previous sealing or DIY attempts
  • Keep pets and children clear of the area while we work
  • Try not to wet indoor joints just before the visit

Advice

Leave it or put it right?

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 once someone inspects it. Older cottages and farmhouses around Crays Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What you get with us

  • Anti-fungal sanitary silicone in wet areas
  • An ARBOMaster approved applicator
  • A 12-month guarantee on all work
  • 4.9 on Google from 180+ five-star reviews

How the job changes by surface

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 before the sealant goes in.

Plasterboard walls

Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach and we will flag it.

Fire rated sealant around Crays Hill

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.

Letting a property close to Wickford station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Managing a site like Crays Hill Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there.

Crays Hill: your questions answered

Will you come out to Crays Hill?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you cover Crays Hill for fire rated sealant?

Yes. Our work covers London and the South East, and Crays Hill is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.

Do you work in flats, HMOs and commercial buildings?

Yes. We regularly work in flats, HMOs, schools and offices while they’re in use and we plan access around the people using them. Early starts or out-of-hours work can be arranged.

Is it worth trying it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

What does intumescent mean?

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant.

What do you put in the joint?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Do you certify the fire stopping?

Ratings and certificates are not something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer.

Are you insured?

Yes. We’re fully insured.

What sealant work cannot fix

A few problems are outside what sealant work can do:

  • Big openings where sealant alone is not the tested solution
  • Certifying a building or signing off its fire safety
  • A wall that isn’t a fire-resisting element to begin with

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