Can I do it myself?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

What happens if it’s left?

A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. Around Middleton, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Honest limits

A few problems are outside what sealant work can do:

  • Sign-off of the building, which sits with building control or your assessor
  • Doors that are not fire doors in the first place
  • Deciding what fire stopping a building needs

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

Joints and surfaces we work on

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

Surface by 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.

Masonry and concrete

Holes through concrete and block are rarely neat. We check the gap size around the service against the product’s tested range.

Signs you need fire rated sealant in Middleton

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.

The most common problems we see are:

  • Gaps where walls meet ceilings or slabs
  • Seals cut through by electricians, plumbers or data installers
  • Joints picked up in a fire-stopping survey
  • Gaps around pipes and cables through fire-resisting walls

For landlords with property near Bow Brickhill station, any gap left by new services in shared walls should be closed with a fire-rated product.

Questions to ask before you book

  • Whether the sealant suits the joint
  • Whether you can choose the colour
  • What guarantee comes with the work
  • Who turns up on the day

Our hiring checklist

What happens on the day

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes anything from a few hours to several days, depending on how many gaps there are. For a job in Middleton, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  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. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Locations and products are noted so you have them on file.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • For indoor joints, keep the area dry beforehand if you can
  • Move anything stored near the joints

Advice

Fire rated sealant in Middleton: 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.

For site and facilities teams at buildings such as Middleton Primary School, service openings in fire-resisting walls need checking after any refurbishment. For buildings such as Church of All Saints, gaps around pipes and cables are worth checking after any building work there.

Middleton: your questions answered

Can you help a landlord with a rental near Bow Brickhill 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.

Will you come out to Middleton?

Yes, Middleton is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Will there be a smell?

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

Do you provide details of the products used?

Yes. We note each location and the product that went in.

Should I try DIY first?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Do you hold any approvals?

Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

Is intumescent sealant the same as fire-rated sealant?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. The specification and the tested detail decide which is used.

Will you assess my building’s fire safety?

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

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Keep the record of products and locations with your fire safety documents
  • Flag any open gap you spot round a pipe or cable
  • Tell trades working in the building that fire seals must be put back
  • Take photos of fire stopping before ceilings or boxing go back

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint and we’ll tell you which one you have.

Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
