Fire rated sealant in Wildmoor

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. If you are dealing with open holes round services passing through fire walls and gaps left after a refit or conversion, we can help, on linear gaps, plasterboard & masonry and flats & HMOs alike.

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

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.

What the job involves on each surface

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall.

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We seal them along their full length so there are no open sections left.

Landlords, agents and businesses in Wildmoor

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

How it works

When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. In a small place like Wildmoor, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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 faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used.

How to prepare

  • Clear the area around the work
  • On commercial sites, let us know about site rules
  • Mention any leaks or damp you’ve noticed

Advice

When to call us in Wildmoor

Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service isn’t always sealed again.

The problems people usually mention when they call include:

  • Cracked or shrunken fire-rated sealant
  • New service routes left unsealed after building work
  • Gaps filled with a product that is not fire-rated
  • Gaps where walls meet ceilings or slabs

If you look after a building such as The Loddon School, gaps opened by contractors for new cabling are a common finding in schools and offices.

What to look for in a quote

  • What insurance they hold
  • How the surfaces are prepared before sealing
  • What happens if the job turns out different
  • When the joint can take water or movement

Fire rated sealant around Wildmoor

If you look after a church, hall or community building such as Church of St. Leonard, service openings in its walls need the right fire-rated sealant, as in any building.

What’s the difference between intumescent and fire-rated sealant?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.

Is standard sealant good enough for a fire gap?

No. Where a fire-rated seal is needed, it has to be a product tested for that use, installed to its details.

Can I choose the sealant colour?

We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.

Do you provide details of the products used?

Yes. Every gap we seal is listed with the product used, so you have it on file.

DIY versus a professional finish

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.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

How to look after the new joints

Looking after new joints is easy:

  • Allow for resealing whenever new services are run
  • Photograph sealed gaps before they’re covered up
  • File the fire-stopping record where your assessor can find it
  • Check risers, ceiling voids and cupboards during building checks

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
