Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. We work on linear gaps, pipe & cable gaps and flats & HMOs, and common reasons people get in touch are open holes round services passing through fire walls and seals cut through by electricians, plumbers or data installers.

Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in Vale of Health.

Do you need fire rated sealant in Vale of Health?

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.

Most people get in touch when they notice something like this:

  • Old fire sealant that has split or come away
  • Linear gaps at the head of walls
  • Gaps flagged on a fire risk assessment
  • Gaps left after a refit or conversion

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

Questions to ask before you book

  • Which sealant they’ll use, and why
  • How the surfaces are prepared before sealing
  • What the cure time is
  • The length of the guarantee

Our hiring checklist

Fire rated sealant in Vale of Health: 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, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.

Vale of Health is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Managing a site like Christ Church Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

DIY sealant or a professional job?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

How we quote for fire rated sealant

There’s no set price list. The quote depends on:

  • How many areas need sealing
  • Access and height
  • Any mould that needs treating
  • The product the joint needs

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What to tell us for a quote

To make quoting easier, let us know:

  • The rough size of the job
  • Where the property is
  • What the problem is, such as mould, gaps, leaks or cracking
  • Any previous sealing or DIY work

Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you’re ready, call 0345 464 0079 or send us an email.

How the visit works

We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to several days, depending on how many gaps there are. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Vale of Health. It helps if you can point us to a visitor permit or a bay close to the door.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • Clear the area around the work
  • Mention if the joints have been sealed before
  • On commercial sites, let us know about site rules

Advice

What the job involves on each surface

Door frames

Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details so the architrave can be refitted.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.

Honest limits

We’ll always be straight with you, so here’s what new sealant will not do:

  • Construction that doesn’t provide fire resistance on its own
  • Doors that are not fire doors in the first place
  • Assessing a building’s fire safety

If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.

What we seal

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

For landlords and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Landlords and agents in Vale of Health can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
