DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Fire rated sealant in Cornhill
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. We work on plasterboard & masonry, flats & HMOs and door frames, and the jobs we see most are open gaps behind door architraves and gaps filled with a product that isn’t fire-rated.
In Scotland’s cities, hotels and student accommodation need sealant work done without emptying the building, so jobs in Cornhill can be programmed room by room, with out-of-hours working possible to arrange.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Workplaces and buildings in Cornhill
For seaside hotels, guest houses and holiday lets around Cornhill, 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. Cornhill has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
If you look after a building such as Northfield Academy, fire-stopping around service openings should be restored whenever new services go in. For buildings such as St Ninian's Church, gaps around pipes and cables are worth checking after any building work there. If you let a flat or house near Aberdeen station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Common questions in Cornhill
How do Scotland’s building regulations apply to fire-rated sealant in Cornhill?
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.
Can you help a landlord with a rental near Aberdeen station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can I use normal mastic around a pipe through a fire wall?
No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you tell me which gaps need fire stopping?
No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.
Can you tell me how many minutes the seal will last?
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.

Quotes for fire rated sealant in Cornhill
Your quote is based on your job. We take into account:
- The old material and how stubborn it is
- Whether the work is at height
- Any mould that needs treating
- Any working-time requirements on site
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

How it works
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes anything from a few hours to several days, depending on how many gaps there are, depending on how much there is to do. For a tenement in Cornhill, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- 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.
- Unsuitable material such as ordinary foam or silicone is cut out.
- The specified fire-rated sealant goes in over any backing its detail requires.

Related advice
Why act early in Cornhill
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Wind-driven rain gets into any failed joint on the outside of a city building, and in Cornhill, damp can spread through stone and plaster before anyone sees it.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and send you a clear quote before any work starts.

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Assessing a building’s fire safety
- Issuing a fire rating or certificate for a building
- Big openings where sealant alone isn’t the tested solution
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.
What we seal
- Service penetrations
- Linear gaps
- Flats & HMOs
- Pipe & cable gaps
- Plasterboard & masonry
- Door frames
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Store the list of sealed gaps with your building paperwork
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Include hidden areas like risers in routine checks
- Plan fire stopping into any work that goes through walls or floors
Do not drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
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.
