Looking after it afterwards

So the new joints stay in good condition:

  • Photograph sealed gaps before they’re covered up
  • Make resealing part of every contractor’s brief
  • Get damaged fire seals looked at promptly
  • Keep the record of products and locations with your fire safety documents

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is generally a straightforward job.

About our fire rated sealant in Carisbrooke

Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment for buildings in Carisbrooke. If you share the list, we can quote for the gaps that need fire-rated sealant. If you are dealing with holes left by a change of layout and standard silicone or caulk in a fire-stopping gap, we can help, on pipe & cable gaps, service penetrations and door frames alike.

Around a place like Carisbrooke, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How we quote for fire rated sealant

Your quote is based on your job. We take into account:

  • The size of the job
  • Mould in or behind the old joints
  • Any working-time requirements on site
  • The old material and how stubborn it is

Combining jobs into one visit is usually more efficient than separate visits. You’ll get one clear quote for the whole job.

Asking for a quote

What to tell us when you ask for a quote:

  • Pictures of the joints, sent by email
  • How we’d reach the joints
  • What’s wrong with the joints now
  • Whether it’s a home or a business

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.

Work for landlords, hotels and businesses

If you manage several properties in or around Carisbrooke, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

How it works

When we arrive, we look over the joints with you first. Surfaces next to the work are protected before work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. A visit to Carisbrooke is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products.

Before we arrive

  • Try not to wet indoor joints just before the visit
  • Let us know about stairs, lifts or work at height
  • Clear the area around the work

Getting a quote

We quote each job on its own, so the first step is telling us about yours. Just call 0345 464 0079 or send us an email with the details and send photos if you have them.

Common problems we fix in Carisbrooke

Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.

People usually contact us when they notice something like this:

  • Fire seals that have cracked with movement
  • Holes left by a change of layout
  • Open joints along the top of partitions
  • Unsealed gaps where pipes and cables go through a wall

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

What your quote should include

  • What happens if the job turns out different
  • How the joint is cleaned and prepared
  • How the colour is chosen
  • What insurance they hold

What the job involves on each surface

Door frames

Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.

Masonry and concrete

Holes through concrete and block are rarely neat. We measure the gap at its widest point to make sure it suits the product.

What sealant work cannot fix

  • Fire risk assessments, which need a qualified assessor
  • Construction that doesn’t provide fire resistance on its own

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