Fire rated sealant for homes and businesses in Greycrook
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, so we work to the manufacturer’s details. If you are dealing with gaps left after a refit or conversion and ordinary sealant used where a fire-rated product was needed, we can put it right, whatever the surface.
If you look after holiday lets, a guest house or a community building in or near Greycrook, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
There’s a 12-month guarantee on every job.

Surface by surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement.
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.
What fire rated sealant looks like in Greycrook
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 don’t certify buildings or do fire risk assessments.
Around Greycrook, as everywhere, fire rated sealant is only as good as the preparation behind it. For buildings such as St Boswells Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Why act early in Greycrook
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

The process
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. Outdoor work around Greycrook depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Before we arrive
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in

Greycrook: your questions answered
Can you do fire rated sealant in Greycrook?
Yes, Greycrook is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Will you come out to Greycrook?
Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
How much does fire rated sealant cost in Greycrook?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can ordinary silicone be used in a fire-stopping gap?
No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Is the work guaranteed?
Yes. All our work carries a 12-month guarantee.

How to look after the new joints
After the cure time, these simple habits help:
- Look in service cupboards and ceiling voids from time to time
- Include fire stopping when you schedule refits
- Take photos of fire stopping before ceilings or boxing go back
- Check whether a sealant can be painted before decorating over it
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
Landlord and commercial work in Greycrook
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
What affects the quote in Greycrook
We don’t publish a price list. The quote depends on:
- How easy the joints are to reach

- The size of the job
- Whether there’s mould to deal with
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
