How we handle fire rated sealant in Woodside Park

We can work through a building room by room or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. If you are dealing with seals cut through by electricians, plumbers or data installers and holes left by a change of layout, we can put it right, on pipe & cable gaps, plasterboard & masonry and linear gaps alike.

London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that is washroom resealing or fire-rated sealant around service openings. Where a building in Woodside Park needs to stay open, work can be planned outside normal hours.

We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

How we quote for fire rated sealant

Call for a quick quote. The main things that affect it are:

  • The old material and how stubborn it is
  • Whether the work is at height
  • The size of the job
  • Which sealant suits the joint

What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Helping us quote

To make quoting easier, please include:

  • Access, such as stairs, a lift or height
  • The type of property
  • Whether it has been sealed before
  • Pictures of the joints, sent by email

There’s no standard price list. Instead, we give you a clear price for your job. To arrange one, phone 0345 464 0079 or drop us an email.

Honest limits

It helps to know what we cannot do too:

  • Assessing a building’s fire safety
  • Large holes that need a different fire-stopping system
  • Walls or floors that weren’t built to resist fire

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

Where we work in Woodside Park

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

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.

Door frames

A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.

Landlords, agents and businesses in Woodside Park

We also work for property managers and facilities teams in Woodside Park and across Greater London. Several sites can be quoted together, and we are fully insured for the work.

Letting agents often deal with us directly. Tell us the address, the job and how access works.

How the visit works

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on how many gaps there are, and the area is left clean. In a London area like Woodside Park, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  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.

Before we arrive

  • Tell us if parking is tricky
  • Let us know if you’ve seen damp or leaks
  • For indoor joints, keep the area dry beforehand if you can

Aftercare tips

Aftercare is simple:

  • Check risers, ceiling voids and cupboards during building checks
  • Photograph sealed gaps before they’re covered up
  • Store the list of sealed gaps with your building paperwork
  • Flag any open gap you spot round a pipe or cable

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.

An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Fire rated sealant around Woodside Park

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 work to the specification you’re 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.

For site and facilities teams at buildings such as Northside Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Rented homes near Oakleigh Park station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as Saint Barnabas' Church, service openings in its walls need the right fire-rated sealant, as in any building.

Your questions about fire rated sealant in Woodside Park

I let a flat near Oakleigh Park station. Can you help?

Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.

Is parking a problem for a job in Woodside Park?

In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.

Do you work in flats, HMOs and commercial buildings?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we’ll plan the work to suit.

Do you take out the old sealant first?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Is intumescent sealant the same as fire-rated sealant?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one option among several. The specification and the tested detail decide which is used.

Do the sealants smell?

Some sealants have a smell while they cure. Ventilation helps.

Is there a guarantee?

Yes, always. Each job is guaranteed for twelve months.

Do you have insurance?

Yes. We’re fully insured for domestic and commercial work.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
