What affects the quote in Letham
You will get a clear quote before any work starts. It’s based on:
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- The size of the job
- Any working-time requirements on site
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk and we’ll talk you through it.
What to tell us for a quote
To make quoting easier, let us know:
- Whether it’s a home or a business
- A few photos by email, if you can
- Whether it has been sealed before
- How many joints, rooms or windows are involved

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.
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the seal has something sound to bond to.

Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Assessing a building’s fire safety
- Openings too large for sealant, which need batts, boards or another system
- Doors that aren’t fire doors in the first place
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.

How it works
At the end, we look at the finished work together. The visit itself normally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. Outside jobs in Letham need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your records.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Fire rated sealant in Letham: local notes
In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. We install fire-rated sealant to the product’s tested details, though we do not certify buildings or do fire risk assessments.
For buildings such as Old Church, service openings in its walls need the right fire-rated sealant, as in any building.

What happens if it’s left?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. Around Letham, water from a failed joint in an older stone home can soak into timber and plaster.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Your questions about fire rated sealant in Letham
Do you cover smaller places like Letham?
Yes, Letham is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do Scottish building rules affect fire-rated sealant work in Letham?
Building work in Scotland comes under the Building (Scotland) Regulations and their 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 carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can you work in occupied buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.
What we are called out for in Letham
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.
Signs it’s time to call us include:
- Gaps where walls meet ceilings or slabs
- Old fire sealant that has split or come away
- Gaps around pipes and cables through fire-resisting walls
- Fire stopping disturbed by later work
Around Letham, as everywhere, fire rated sealant is only as good as the preparation behind it.
