What affects the cost of fire rated sealant

We quote each job individually. These are the things that affect it:

  • How much there is to do
  • Whether the work is at height
  • Whether there’s mould to deal with
  • Whether old sealant or filler has to be cut out

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

What we need to know

There’s no need for technical detail. It helps if you can tell us:

  • Photos by email, if that is easy
  • Any previous sealing or DIY work
  • Access, such as stairs, a lift or height
  • The problem you’ve noticed

For fire rated sealant in Oakwood, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you will get a clear quote before work begins.

Fire rated sealant for homes and businesses in Oakwood

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 is the part we focus on, gap by gap. If you are dealing with standard silicone or caulk in a fire-stopping gap and gaps where walls meet ceilings or slabs, we can put it right, on door frames, plasterboard & masonry and flats & HMOs alike.

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

A 12-month guarantee comes as standard.

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Fire rated sealant in Oakwood: local notes

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. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.

As a London address, Oakwood can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you look after a church, hall or community building such as St Thomas's Church, service openings in its walls need the right fire-rated sealant, as in any building. Schools such as Wolfson Hillel Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

FAQs for Oakwood

Is Oakwood in your area for fire rated sealant?

Yes. Our work covers London and the South East, and Oakwood is part of that. Just call 0345 464 0079 or email us with a few details of the job.

I let a flat near Winchmore Hill station. Can you help?

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

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.

Is there any odour?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.

What does fire rated sealant cost?

We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Can you give us a record of the work?

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

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.

How the job changes by surface

Plasterboard walls

We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing so the sealant bonds.

When it isn’t the sealant

Sealant isn’t the answer to every problem, and we’ll tell you before we start. Sealant won’t put right:

  • Large holes that need a different fire-stopping system
  • Deciding what fire stopping a building needs
  • Walls or floors that weren’t built to resist fire

Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

Where we work in Oakwood

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

What we do, step by step

The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job generally takes from a few hours to a few days, depending on the number of gaps and the access, and we tell you how long to leave it before we go. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products.

Preparing for the visit

  • Keep children and pets away from the work area
  • Let us know about earlier repairs to the joints
  • Let us know about parking restrictions

Advice

Why deal with it now?

A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
