Fire rated sealant in Nash, done properly

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and the gap is resealed with a product tested for that use. We work on linear gaps, service penetrations and plasterboard & masonry, and the jobs we see most are linear gaps at the head of walls and joints picked up in a fire-stopping survey.

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

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

Common questions in Nash

Can you do fire rated sealant in Nash?

Yes. Our work covers London and the South East, and Nash is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.

Can you help a landlord with a rental near Milton Keynes Central station?

How much does fire rated sealant cost in Nash?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before we start.

Is it OK to seal over old sealant?

No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

Where are you based?

We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.

Is it messy?

Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

Will there be a smell?

Sometimes, a little. Any smell clears as the sealant cures.

What information do you need?

A short description and the location. We’ll ask anything else we need to know.

Common problems we fix in Nash

Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

Most people get in touch when they notice one of these:

  • New service routes left unsealed after building work
  • Standard silicone or caulk in a fire-stopping gap
  • Open holes round services passing through fire walls
  • Open gaps behind door architraves

Letting a property close to Milton Keynes Central station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Choosing a sealant specialist

What affects the quote in Nash

We quote each job individually. This is what makes a difference:

  • Which sealant suits the joint
  • The number and length of the joints
  • How much old sealant there is and how hard it is to remove
  • Whether there’s mould to deal with

Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

What we need to know

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • Any previous sealing or DIY work
  • Pictures of the joints, sent by email
  • Roughly how big the job is
  • Whether it’s a home or a business

To get a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We’ll give you a clear quote before any work starts.

How the visit works

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Nash, access is normally 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. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed.
  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 files.

How to prepare

  • Mention any tricky access
  • Mention any sign-in or site rules at work premises
  • Tell us about any water getting in

How to get a quote

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Different surfaces, different methods

Flats and HMOs

Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and record where they are.

Linear gaps

Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement.

Fire rated sealant in Nash: local notes

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.

If you look after a church, hall or community building such as Church of All Saints, gaps around pipes and cables are worth checking after any building work there.

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Leave it or put it right?

Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing once someone inspects it. In a small place like Nash, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
