Fire rated sealant in Lambourn

Bigger jobs can be worked through in stages, flat by flat or floor by floor, noting the locations and products as we go. It gives you a list to keep with the building’s fire safety documents. If you are dealing with linear gaps at the head of walls and cracked or shrunken fire-rated sealant, we can put it right, on door frames, linear gaps and service penetrations alike.

In a smaller place like Lambourn, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. The work is the same as in a big building, just on a smaller scale.

We stand behind the work with a one-year guarantee, so you are covered after we have gone.

What we do, step by step

The work is kept neat and contained to the area we’re working on. The job generally takes a few hours for a handful of gaps, and longer for a whole building, and we explain the cure time before we leave. Parking around Lambourn is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. Before starting, we go through the specification or action list with you.
  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. We hand over a list of locations and products for your records.

Preparing for the visit

  • Tell us about any water getting in
  • Mention if the joints have been sealed before
  • Try not to wet indoor joints just before the visit

Advice

When it isn’t the sealant

In fairness, some problems need a different trade:

  • Large holes that need a different fire-stopping system
  • A wall that isn’t a fire-resisting element to begin with
  • Doors that are not fire doors in the first place

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

Where we work in Lambourn

Quotes for fire rated sealant in Lambourn

Your quote is based on your job. We look at:

  • Mould in or behind the old joints
  • The number and length of the joints
  • Whether old sealant or filler has to be cut out
  • The type of sealant required

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Helping us quote

Before you ask for a quote, have a think about:

  • The rough size of the job
  • A few photos by email, if you can
  • The problem you’ve noticed
  • If someone has resealed it before

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, ring 0345 464 0079 or email us.

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

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.

Leave it or put it right?

An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Homes in smaller places like Lambourn can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Fire rated sealant around Lambourn

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

If you look after a church, hall or community building such as Church of St Michael and All Angels, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like Lambourn CofE Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

Different surfaces, different methods

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for the gap we’re sealing.

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
