About our fire rated sealant in Knightswood
We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. If you’re dealing with damaged fire sealant left by other trades and door frames with gaps between frame and wall, we can help, on linear gaps, door frames and plasterboard & masonry alike.
In Scotland’s cities, hotels and student accommodation need sealant work done without emptying the building, so work in Knightswood can be planned room by room, and out of hours where needed.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

How it works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building for a typical job. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Knightswood, tell us the floor, how the door entry system works and where we can park nearby.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Let us know about parking restrictions

Advice
Why act early in Knightswood
Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own that doesn’t depend on other work. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Knightswood, damp can travel a long way before it shows.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Workplaces and buildings in Knightswood
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; we don’t certify buildings or carry out fire risk assessments.
Schools such as Knightswood Secondary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Knightswood St Margaret's Parish Church, service openings in its walls need the right fire-rated sealant, as in any building.

Surface by surface
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run leaving no stretch unsealed.
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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Quotes for fire rated sealant in Knightswood
For a quick quote, just ask. The main things that affect it are:
- Mould in or behind the old joints
- The size of the job
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- What’s wrong with the joints now
- Any previous sealing or DIY work
- A few photos by email, if you can
- If it’s domestic, commercial or a hotel

Knightswood questions
Can you help a landlord with a rental near Westerton station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.
How do Scotland’s building regulations apply to fire-rated sealant in Knightswood?
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 carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then email us at info@mrmastic.co.uk.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
How much does fire rated sealant cost in Knightswood?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Can you work in occupied buildings?
Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we’ll plan around it.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
When it isn’t the sealant
We will not take on work that will not last, so here’s what sealant cannot put right:
- Walls or floors that weren’t built to resist fire
- Sign-off of the building, which sits with building control or your assessor
- Fire doors that need new seals, closers or hardware
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Flats & HMOs
- Service penetrations

When to call us in Knightswood
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
Keep an eye out for these signs:
- Sealant items on a fire risk assessment action list
- Gaps filled with a product that isn’t fire-rated
- Unsealed gaps where pipes and cables go through a wall
- Linear gaps at the head of walls
Letting a property close to Westerton station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
