Fire rated sealant in Northbridge Street

Fire rated sealant in Northbridge Street, done properly

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. We work on door frames, linear gaps and service penetrations, and common reasons people get in touch are fire seals that have cracked with movement and open joints along the top of partitions.

Somewhere as small as Northbridge Street, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

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

Workplaces and buildings in Northbridge Street

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. Northbridge Street has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.

If you let a flat or house near Robertsbridge station, any gap left by new services in shared walls should be closed with a fire-rated product. Schools such as Salehurst Church of England Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

What sealant work can’t fix

We will always be straight with you, so here’s what new sealant will not do:

  • Problems with the door itself rather than the gap around the frame
  • Issuing a fire rating or certificate for a building
  • Deciding what fire stopping a building needs

If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.

Where we work in Northbridge Street

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

Looking after it afterwards

Looking after new joints is easy:

  • Keep the record of products and locations with your fire safety documents
  • Do not paint over fire sealant until it has cured
  • Allow for resealing whenever new services are run
  • Keep pictures of seals that will be hidden

Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so you can show it was dealt with.

Work for landlords, hotels and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for.

How the visit works

There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes from a few hours to a few days, depending on the number of gaps and the access, including the tidy-up. Somewhere as small as Northbridge Street, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

Preparing for the visit

  • Clear the area around the work
  • Let us know if you’ve seen damp or leaks
  • Let us know about parking restrictions

Advice

Northbridge Street questions

Do you work in hotels near Northbridge Street?

Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.

Is Northbridge Street within the area you cover?

Yes. Northbridge Street is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you offer different sealant colours?

We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.

What’s the difference between intumescent and fire-rated sealant?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one option among several. The specification and the tested detail decide which is used.

Where are you based?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

Can you do several jobs on one visit?

Yes. Just list everything you need.

Do you do fire sealant around door frames?

Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself.

Are you an approved applicator?

Yes. We’re an ARBOMaster approved applicator.

Should I try it myself first?

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

When to call us in Northbridge Street

Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.

Keep an eye out for these signs:

  • Fire stopping disturbed by later work
  • Gaps around pipes and cables through fire-resisting walls
  • Sealant items on a fire risk assessment action list
  • Unsealed gaps around fire door frames

Community buildings like The Parish Church of St Mary are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Before booking anyone

  • How the colour is chosen
  • What product goes in the joint
  • Who does the work, and how experienced they are
  • What preparation is included

10 questions to ask before you book

Why it’s worth doing now in Northbridge Street

An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Older cottages and farmhouses around Northbridge Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
