We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap. If you have fire seals that have cracked with movement and open gaps behind door architraves, we can put it right, whatever the surface.

Fire rated sealant around Cullivoe
For seaside hotels, guest houses and holiday lets around Cullivoe, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details; we do not certify buildings or carry out fire risk assessments.
Community buildings like St Olaf's Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
Cullivoe is in the Shetland Islands. Every kind of property in Cullivoe is covered for fire rated sealant, old or new, large or small. Every job comes with our one-year guarantee. Cullivoe is one of 63 towns and villages in the Shetland Islands we cover.

Leave it or put it right?
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. In an older home around Cullivoe, damp from a failed joint can get into timber and plaster.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Questions from Cullivoe
Is Cullivoe in your area for fire rated sealant?
Yes, Cullivoe is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
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. Fire-rated sealant has to go in to the product’s tested details, and we follow them. We don’t certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated to help seal the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
What fire rating will the seal have?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and list the locations and products for you.
Can ordinary silicone be used in a fire-stopping gap?
No. A gap that needs fire stopping needs a tested fire-rated product.
Can I choose the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.
Can you give us a record of the work?
Yes. We record the locations we’ve sealed and the products used.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months, large or small.
Do you need fire rated sealant in Cullivoe?
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. Rushed fire stopping is common.
The most common problems we see are:
- Open gaps behind door architraves
- Ordinary sealant used where a fire-rated product was needed
- Linear gaps at the head of walls
- Joints picked up in a fire-stopping survey
Around Cullivoe, as everywhere, fire rated sealant is only as good as the preparation behind it.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How it works
Before we leave, we go over the finished joints with you. The work normally takes anything from a few hours to several days, depending on how many gaps there are, depending on the size of the job. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules

Advice
What affects the cost of fire rated sealant
Call for a quick quote. The main things that affect it are:
- The number and length of the joints
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
