What the job involves on each surface

Linear gaps

A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both, following the tested detail.

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.

What we do, step by step

All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a handful of gaps, and longer for a whole building. A visit to Sawbridgeworth is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • Mention any parking rules near the property
  • Mention any sign-in or site rules at work premises
  • Tell us about any water getting in

What sealant work can’t fix

Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:

  • A wall that isn’t a fire-resisting element to begin with
  • Fire doors that need new seals, closers or hardware
  • Certifying a building or signing off its fire safety

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Joints and surfaces we work on

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

When to call us in Sawbridgeworth

Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.

Look out for any of the following:

  • Unsealed gaps around fire door frames
  • Gaps left after a refit or conversion
  • Unsealed gaps where pipes and cables go through a wall
  • Gaps filled with a product that is not fire-rated

Managing a site like Fawbert and Barnard Infants' School? Then service openings in fire-resisting walls need checking after any refurbishment.

  • Is VAT in the price?

Choosing a sealant specialist

DIY sealant or a professional job?

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

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Sawbridgeworth: your questions answered

Is Sawbridgeworth in your area for fire rated sealant?

Yes. We work across London and the South East, and Sawbridgeworth is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.

Can you help a landlord with a rental near Sawbridgeworth station?

Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.

What do you need from me for a quote?

The location, the problem and the rough size of the job. Photos by email help too.

Can you match the sealant colour?

In most cases you can choose. We will explain which colours are available and agree one before any work starts.

Is intumescent sealant the same as fire-rated sealant?

An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.

Can you do several jobs on one visit?

Yes, we can. More than one area can be quoted together.

What fire rating will the seal have?

We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.

Are you an approved applicator?

Yes. We hold ARBOMaster approved applicator status, and we are fully insured.

Keeping the joints in good condition

How long the joints last depends on use and care. Here’s what we suggest:

  • Store the list of sealed gaps with your building paperwork
  • Look in service cupboards and ceiling voids from time to time
  • Keep photos of seals that will be hidden
  • Include fire stopping when you schedule refits

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.
