How we handle fire rated sealant in Roxbourne

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. We work on flats & HMOs, door frames and service penetrations, and the jobs we see most are open joints along the top of partitions and standard silicone or caulk in a fire-stopping gap.

London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Roxbourne, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.

All our work comes with a 12-month guarantee.

Keeping the joints in good condition

So the new joints stay in good condition:

  • Do not paint over fire sealant until it has cured
  • Never patch a fire seal with standard sealant
  • Make resealing part of every contractor’s brief
  • Allow for resealing whenever new services are run

Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.

Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

Roxbourne: your questions answered

Can you do fire rated sealant in Roxbourne?

Yes, Roxbourne is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.

Can you help a landlord with a rental near South Ruislip station?

Can I add another job to the visit?

Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.

Can you tell me how many minutes the seal will last?

We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.

How much does fire rated sealant cost in Roxbourne?

There’s no set price, as it 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.

Do you do fire sealant around door frames?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door, its seals and closer are for a door specialist.

Are you ARBOMaster approved?

Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.

Where is Mr Mastic based?

We work from Crawley. Our applicators cover Roxbourne.

Fire rated sealant in Roxbourne: local notes

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

As a London address, Roxbourne can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Managing a site like The Moriah Jewish Day School? Then fire-stopping around service openings should be restored whenever new services go in.

Can I do it myself?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

How we quote for fire rated sealant

The quote reflects the job in front of us. We take into account:

  • How easy the joints are to reach
  • Whether old sealant or filler has to be cut out
  • The number of rooms or windows
  • When we can work, for business premises

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Asking for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Any previous sealing or DIY work
  • Any access issues, like height or stairs
  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking

Need a quote? Please ring 0345 464 0079 or drop us an email with a few details. We’ll explain what we’d do and give you a clear quote before work begins.

What we are called out for in Roxbourne

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

The problems people usually mention when they call include:

  • Damaged fire sealant left by other trades
  • Unsealed gaps around fire door frames
  • Gaps filled with a product that isn’t fire-rated
  • Gaps where walls meet ceilings or slabs

If you let a flat or house near South Ruislip station, any gap left by new services in shared walls should be closed with a fire-rated product.

Before booking anyone

  • Who turns up on the day
  • How the surfaces are prepared before sealing
  • Are they insured?
  • What product goes in the joint

What sealant work can’t fix

We won’t take on work that will not last, so here’s what sealant can’t put right:

  • Fire risk assessments, which need a qualified assessor
  • Openings too large for sealant, which need batts, boards or another system
  • Doors that are not fire doors in the first place

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

What we seal

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

What we do, step by step

When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In Roxbourne, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Clear the area around the work
  • Keep pets and children clear of the area while we work
