Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.

Looking after it afterwards

So the new joints stay in good condition:

  • File the fire-stopping record where your assessor can find it
  • Check risers, ceiling voids and cupboards during building checks
  • Ask which product was used before you paint
  • Take photos of fire stopping before ceilings or boxing go back

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and get them seen to.

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

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

FAQs for Bàgh a'Chaisteil

Do you cover Bàgh a'Chaisteil for fire rated sealant?

Yes. We work across all of Scotland, and Bàgh a'Chaisteil is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing.

Are the rules for fire-rated sealant different in Scotland?

Scotland has its own building regulations, the Building (Scotland) Regulations, with their own technical handbooks. Whatever the rules, fire-rated sealant has to be installed to the manufacturer’s tested details, and that is how we fit it. We do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.

Can new sealant go over the old?

No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

Do you take out the old sealant first?

Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Is there a guarantee?

Yes, always. There’s a 12-month guarantee on every job, wherever you are.

Do you take on fire stopping in schools and offices?

Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.

What does fire rated sealant cost?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.

Is standard sealant good enough for a fire gap?

No. It might close the gap, but it is not a fire-rated seal. Use a product tested for that gap and service, or ask us to do it.

Signs you need fire rated sealant in Bàgh a'Chaisteil

Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.

Common reasons people contact us are:

  • Cracked or shrunken fire-rated sealant
  • Standard silicone or caulk in a fire-stopping gap
  • Damaged fire sealant left by other trades
  • Open gaps behind door architraves

If you look after a church, hall or community building such as Church of our Lady, older buildings that have had new heating or wiring often have service gaps worth checking.

What your quote should include

  • The length of the guarantee
  • What product goes in the joint
  • What the quote includes, VAT included or not
  • Are they insured?

Our hiring checklist

Why act early in Bàgh a'Chaisteil

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Why Bàgh a'Chaisteil customers choose us

  • We leave the area clean and tidy
  • Domestic, commercial and hotel work
  • Over 20 years’ experience
  • A 12-month guarantee on all work

DIY versus a professional finish

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Fire-rated sealant is installed to the manufacturer’s tested details, though we don’t certify buildings or do fire risk assessments.
