Fire rated sealant in Nursted

Fire rated sealant in Nursted

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on flats & HMOs, pipe & cable gaps and door frames, and people most often call us about sealant items on a fire risk assessment action list and unsealed gaps around fire door frames.

Work in a small place like Nursted is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

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

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What we cannot put right

New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:

  • Big openings where sealant alone is not the tested solution
  • Issuing a fire rating or certificate for a building
  • Assessing a building’s fire safety

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

Surfaces we seal

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

Nursted questions

Do you work for landlords with property near Petersfield station?

Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Will you come out to Nursted?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you take out the old sealant first?

Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.

What do you need from me for a quote?

The location, the problem and the rough size of the job. If you can, email a few pictures.

How much does fire rated sealant cost in Nursted?

Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or send us an email with a short description of the job.

Will you leave a mess?

No. The area is protected while we work and cleaned up afterwards.

Do you carry out fire risk assessments?

No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.

What sealant do you use?

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

When to call us in Nursted

Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service isn’t always sealed again.

Signs it’s time to call us include:

  • Old fire sealant that has split or come away
  • Linear gaps at the head of walls
  • New service routes left unsealed after building work
  • Door frames with gaps between frame and wall

If you let a flat or house near Petersfield station, any gap left by new services in shared walls should be closed with a fire-rated product.

10 questions to ask before you book

What affects the quote in Nursted

Your quote is based on your job. We take into account:

  • Any working-time requirements on site
  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out
  • Access and height

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What to tell us for a quote

When you call or email, these details help:

  • If it’s domestic, commercial or a hotel
  • What’s wrong with the joints now
  • If someone has resealed it before
  • Access, such as stairs, a lift or height

If you are in Nursted and need fire rated sealant, call 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.

What the job involves on each surface

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone is not the right fix.

Plasterboard walls

Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard.

Commercial buildings in Nursted

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

Managing a site like The Petersfield School? Then service openings in fire-resisting walls need checking after any refurbishment.

What we do, step by step

Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually 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 Nursted needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  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.

Preparing for the visit

  • Clear items away from the joints we’re working on
  • Mention any tricky access
  • Keep children and pets away from the work area
