Trusted fire rated sealant in Langbank

Fire rated sealant for homes and businesses in Langbank

Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through. We work on linear gaps, door frames and pipe & cable gaps, and people most often call us about joints picked up in a fire-stopping survey and fire seals that have cracked with movement.

Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. Each needs sound sealant in its washrooms and kitchens, and fire-rated joints kept in good order.

We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

How the job changes by surface

Service penetrations

Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in.

Door frames

The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.

What we do, step by step

A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes a few hours for a handful of gaps, and longer for a whole building. Outside jobs in Langbank need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

Getting ready for the visit

  • Let us know about parking restrictions
  • Mention if the joints have been sealed before
  • Where the joints are inside, avoid wetting them before we arrive

Advice

Quotes for fire rated sealant in Langbank

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

  • The number and length of the joints
  • Which sealant suits the joint
  • Mould in or behind the old joints
  • How easy the joints are to reach

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. You will know the price before we begin.

What to tell us for a quote

What to tell us when you ask for a quote:

  • Whether it has been sealed before
  • The type of property
  • Any access issues, like height or stairs
  • What’s wrong with the joints now

For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved before giving you a price.

Looking after it afterwards

After the cure time, these simple habits help:

  • Don’t paint over fire sealant until it has cured
  • Plan fire stopping into any work that goes through walls or floors
  • Never patch a fire seal with standard sealant
  • File the fire-stopping record where your assessor can find it

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint and we’ll tell you which one you have.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Leave it or put it right?

Squirting in whichever sealant is nearest doesn’t make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Around Langbank, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Yes, we can. Several rooms, windows or areas can go on one quote.
