What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access and height
- The number and length of the joints
- Whether there’s mould to deal with
- The product the joint needs
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Photos by email are helpful but not essential. Try to tell us:

Fire rated sealant in Dounby
We can work through a building room by room or floor by floor. That record is useful for your files and for whoever looks at the building next. We work on pipe & cable gaps, linear gaps and service penetrations, and the jobs we see most are open holes round services passing through fire walls and fire stopping disturbed by later work.
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 is not right with it in that time, tell us and we’ll put it right.

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 matched to the joint and its conditions.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Common problems we fix in Dounby
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
The most common problems we see are:
- Old fire sealant that has split or come away
- Gaps around pipes and cables through fire-resisting walls
- Gaps where walls meet ceilings or slabs
- Holes left by a change of layout
For jobs in and around Dounby, choosing the right material for each joint is as important as a tidy finish.

What we cannot put right
To be straight with you, there are a few things sealant won’t fix:
- Deciding what fire stopping a building needs
- Issuing a fire rating or certificate for a building
- Openings too large for sealant, which need batts, boards or another system
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.

Commercial buildings in Dounby

For landlords and businesses
Letting agents and landlords in Dounby can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Check whether a sealant can be painted before decorating over it
- Photograph sealed gaps before they’re covered up
- Allow for resealing whenever new services are run
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.

Questions from Dounby
Can you do fire rated sealant in Dounby?
Yes. We work across all of Scotland, and Dounby is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
How do Scotland’s building regulations apply to fire-rated sealant in Dounby?
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 do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
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. We agree the price before any work begins.
What’s the difference between intumescent and fire-rated sealant?
Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Do you have insurance?
Yes. Full insurance covers our work.
The process
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes from a few hours to a few days, depending on the number of gaps and the access. Outdoor work around Dounby 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 plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- 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.
How to prepare
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
