Need fire rated sealant in Long Sutton?

Can I do it myself?

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.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Fire rated sealant for homes and businesses in Long Sutton

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. If you are dealing with gaps flagged on a fire risk assessment and unsealed gaps where pipes and cables go through a wall, we can help, whatever the surface.

For a small place like Long Sutton, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.

The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

Fire rated sealant in Long Sutton: 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, 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.

Rented homes near Bentley (Hampshire) station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a building such as Long Sutton Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

The process

On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Long Sutton, the journey is planned in advance: 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. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. We remove any old or unsuitable filler and clean the gap.
  3. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about access, such as stairs, a lift or high-level joints
  • For indoor joints, keep the area dry beforehand if you can

Questions from Long Sutton

Is Long Sutton in your area for fire rated sealant?

Yes. We work across London and the South East, and Long Sutton is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.

Do you cover smaller places like Long Sutton?

Yes. Long Sutton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you do several jobs on one visit?

Yes. More than one area can be quoted together.

How much does fire rated sealant cost in Long Sutton?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.

Where do you work from?

We work from Crawley. Our applicators cover Long Sutton, along with the rest of our area.

What sealant do you use?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.

Do the sealants smell?

There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

Do you work in flats, HMOs and commercial buildings?

Yes. Occupied flats, HMOs, offices and schools are all fine and we plan access around the people using them. Early starts or out-of-hours work can be arranged where it’s needed.

How to look after the new joints

After the cure time, these simple habits help:

  • File the fire-stopping record where your assessor can find it
  • Never patch a fire seal with standard sealant
  • Tell trades working in the building that fire seals must be put back
  • Include hidden areas like risers in routine checks

Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded.

Surface by surface

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for the gap we are sealing.

Leave it or put it right?

Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Around Long Sutton, older homes often have timber in their 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 the work is at height. We take all of that into account in your quote.

  • Any old sealant cut out fully, not covered over
  • 180+ five-star Google reviews

Read our cost guide or our reviews.

When something else is needed

A few problems are outside what sealant work can do:

  • Certifying a building or signing off its fire safety
  • Doors that are not fire doors in the first place
  • Walls or floors that weren’t built to resist fire

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

What we seal

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

When to call us in Long Sutton

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common particularly when it was the last job before handover.

These are the problems we’re asked about most:

  • Open gaps behind door architraves
  • Seals cut through by electricians, plumbers or data installers
  • Gaps around pipes and cables through fire-resisting walls
  • Open joints along the top of partitions

For buildings such as Church of All Saints, older buildings that have had new heating or wiring often have service gaps worth checking.
