How it works

Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. Somewhere as small as Priestwood Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  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.

Before we arrive

  • Tell us about access, such as stairs, a lift or high-level joints
  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about earlier repairs to the joints

How we handle fire rated sealant in Priestwood Green

We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you’re dealing with holes left by a change of layout and gaps around pipes and cables through fire-resisting walls, we can help.

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

There’s a 12-month guarantee on every job, whatever its size.

DIY sealant or a professional job?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

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.

Commercial buildings in Priestwood Green

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.

Community buildings like Church of Our Lady of the Meadow are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as Culverstone Green Primary School, service openings in fire-resisting walls need checking after any refurbishment.

For landlords and businesses

Landlords and agents in Priestwood Green can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Questions from Priestwood Green

Do you work for landlords with property near Sole Street station?

Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.

Will you come out to Priestwood Green?

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

Is intumescent sealant the same as fire-rated sealant?

An intumescent sealant expands when it gets hot to help seal the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

Does someone need to be in?

If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.

Is there a guarantee?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.

Is it messy?

Not at all. The area is protected while we work and cleaned up afterwards.

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.

Do you hold any approvals?

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

What sealant work cannot fix

We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

  • Deciding what fire stopping a building needs
  • Certifying a building or signing off its fire safety
  • Openings too large for sealant, which need batts, boards or another system

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

Joints and surfaces we work on

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

What the job involves on each surface

Flats and HMOs

In occupied buildings, we plan the order of work with you. Access to flats and common areas is agreed in advance.

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail, and we will tell you.

Looking after it afterwards

Simple care keeps the joints in good condition. We recommend:

  • Look in service cupboards and ceiling voids from time to time
  • Photograph sealed gaps before they’re covered up
  • Check whether a sealant can be painted before decorating over it
  • Keep the record of products and locations with your fire safety documents

Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the list grows.

What we are called out for in Priestwood Green

Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.

The problems people generally mention when they call include:

  • Open holes round services passing through fire walls
  • Holes left by a change of layout
  • Door frames with gaps between frame and wall
  • Joints picked up in a fire-stopping survey

For landlords with property near Sole Street station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
