Need fire rated sealant in Greengate?

When something else is needed

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Problems with the door itself rather than the gap around the frame
  • Sign-off of the building, which sits with building control or your assessor
  • Big openings where sealant alone is not the tested solution

If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

How we handle fire rated sealant in Greengate

Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That’s the part we focus on, gap by gap. Typical jobs include gaps left after a refit or conversion and standard silicone or caulk in a fire-stopping gap, across door frames, pipe & cable gaps and plasterboard & masonry.

In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Greengate, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

What affects the quote in Greengate

Some jobs are bigger than they look, and some smaller. The main factors:

  • How much there is to do
  • Whether there’s mould to deal with
  • The product the joint needs
  • How many rooms, windows or areas are involved

What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Helping us quote

To make quoting easier, please include:

  • The type of property
  • Roughly how big the job is
  • Access, such as stairs, a lift or height
  • A few pictures by email, if you can

How the job changes by surface

Door frames

Frame gaps are normally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.

Service penetrations

New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in.

The process

There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours for a handful of gaps, and longer for a whole building for a typical job. In Greengate, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit 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

  • Tell us about any previous sealing or DIY attempts
  • Try not to wet indoor joints just before the visit
  • Plan for the work area to be out of bounds to pets and children

When to call us in Greengate

A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.

If you can see any of these, it’s time to have the joints looked at:

  • Joints picked up in a fire-stopping survey
  • Seals cut through by electricians, plumbers or data installers
  • Unsealed gaps where pipes and cables go through a wall
  • Open gaps behind door architraves

If you look after a church, hall or community building such as St Andrew's Church, gaps around pipes and cables are worth checking after any building work there.

Our hiring checklist

DIY versus a professional finish

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

A careful DIYer can reseal a simple joint, 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.

Your questions about fire rated sealant in Greengate

Do you work for landlords with property near West Ham station?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.

Do you work for hotels and guest houses in Greengate?

Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Are you fully insured?

Yes, we’re fully insured for every job we do.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Can you give us a record of the work?

Yes. Locations and products are written up when we finish. If you need photos or a set layout, ask when you get a quote.

How long will you be here?

A typical job takes a few hours for a handful of gaps, and longer for a whole building, including the preparation. We’ll confirm how long when we quote.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.

Is standard sealant good enough for a fire gap?

No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.

Why act early in Greengate

Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Why us?

  • Anti-fungal silicone where joints get wet
  • Over 20 years’ experience
  • Approved under the ARBOMaster scheme
  • We never seal over old sealant
