Fire rated sealant for homes and businesses in Chartway Street

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We are often asked to deal with seals cut through by electricians, plumbers or data installers and ordinary sealant used where a fire-rated product was needed, across door frames, service penetrations and plasterboard & masonry.

Work in a small place like Chartway Street is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

How to look after the new joints

Looking after new joints is easy:

  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Take pictures of fire stopping before ceilings or boxing go back
  • Flag any open gap you spot round a pipe or cable
  • Plan fire stopping into any work that goes through walls or floors

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint, so ask us which we used.

Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Landlord and commercial work in Chartway Street

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

We regularly work with letting and managing agents. Tell us the address, the job and how access works.

What the job involves on each surface

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.

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 sealant bonds.

When something else is needed

In fairness, there are a few things sealant will not fix:

  • Large holes that need a different fire-stopping system
  • Issuing a fire rating or certificate for a building
  • Problems with the door itself rather than the gap around the frame

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

Surfaces we seal

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

Fire rated sealant in Chartway Street: 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 work to the specification you’re given, installing the product to its tested details.

For site and facilities teams at buildings such as Kingswood Primary School, fire-stopping around service openings should be restored whenever new services go in. Community buildings like St Peter's and St Paul's Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Common problems we fix in Chartway Street

Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service isn’t always sealed again.

Signs it’s time to call us include:

  • Holes left by a change of layout
  • Unsealed gaps where pipes and cables go through a wall
  • Door frames with gaps between frame and wall
  • Fire seals that have cracked with movement

For landlords with property near Harrietsham station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Our hiring checklist

The process

On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In a small place like Chartway Street, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. Any non-fire-rated filler is removed and the gap cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your records.

Getting ready for the visit

  • Let us know about earlier repairs to the joints
  • Mention any sign-in or site rules at work premises
  • Plan for the work area to be out of bounds to pets and children
