How we quote for fire rated sealant

You’ll get a clear quote before work begins. It takes into account:

  • The old material and how stubborn it is
  • Whether there’s mould to deal with
  • How many areas need sealing
  • The number and length of the joints

Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

What we need to know

You don’t need to know the technical terms. Just tell us:

  • How many joints, rooms or windows are involved
  • What the problem is, such as mould, gaps, leaks or cracking
  • Pictures of the joints, sent by email
  • Access, such as stairs, a lift or height

Every job is quoted individually, so the first step is telling us about yours. Just call 0345 464 0079 or send us an email with the details and send pictures if you have them.

Fire rated sealant in Hatch End, done properly

Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. If you are dealing with linear gaps at the head of walls and gaps flagged on a fire risk assessment, we can put it right, whatever the surface.

Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Hatch End can’t close.

Every job comes with a one-year guarantee, wherever you are in Greater London.

Why it’s worth doing now in Hatch End

Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Hatch End, the repair is bigger than a sealant job.

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email.

Should I try it myself first?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

How it works

We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on how many gaps there are. In Hatch End, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  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.

Before we arrive

  • Clear the area around the work
  • Tell us about any water getting in
  • Let us know about parking restrictions

Surface by surface

Plasterboard walls

Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard.

Door frames

The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.

What fire rated sealant looks like in Hatch End

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.

For buildings such as Pinner Baptist Church, service openings in its walls need the right fire-rated sealant, as in any building. Schools such as Pinner Park Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. As a London address, Hatch End can be tricky for parking: let us know about parking bays, permits or a driveway.
