Surface by surface
Linear gaps

Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in.
About our fire rated sealant in Downfield
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. We work on linear gaps, pipe & cable gaps and door frames, and people most often call us about cracked or shrunken fire-rated sealant and new service routes left unsealed after building work.
Scotland’s cities have offices, hotels, student flats, care homes and tenement blocks looked after by factors. In Downfield, that can mean resealing washrooms room by room or fire-rated sealant around pipes and cables in common areas.
Every job comes with our 12-month guarantee, wherever you are in Dundee.

When something else is needed
A few problems are outside what sealant work can do:
- Big openings where sealant alone is not the tested solution
- Doors that aren’t fire doors in the first place
- Construction that does not provide fire resistance on its own

How we quote for fire rated sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether the work is at height
- When we can work, for business premises
- Whether there’s mould to deal with
- The number and length of the joints
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
What we need to know
Photos help, but a description is a good start. Please mention:
- How many joints, rooms or windows are involved
- The address or postcode of the job
- The type of property
- Access, such as stairs, a lift or height

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Why act early in Downfield
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Private landlords in Downfield must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
Why us?
- 12-month guarantee on every job
- Trusted Arbo and Everbuild sealants
- 20+ years of sealant experience
- Tidy, careful work
Common problems we fix in Downfield
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
Most people get in touch after spotting one of these:
- Standard silicone or caulk in a fire-stopping gap
- Sealant items on a fire risk assessment action list
- Old fire sealant that has split or come away
- Open holes round services passing through fire walls
Rented homes near Dundee station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

How it works
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start.

- 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.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.

Your questions about fire rated sealant in Downfield
Are the rules for fire-rated sealant different in Scotland?
Building work in Scotland comes under the Building (Scotland) Regulations and their technical handbooks. Whatever the rules, fire-rated sealant has to be installed to the manufacturer’s tested details, and that’s how we fit it. 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 Dundee station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Can you work in occupied buildings?
Yes. Occupied flats, HMOs, offices and schools are all fine, with access planned around residents or staff. Early starts or out-of-hours work can be arranged if that suits the building.
Do you have insurance?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Do you offer different sealant colours?
Generally, yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
What’s the difference between intumescent and fire-rated sealant?
An intumescent sealant expands when it gets hot 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.
Can you fill the gap behind a fire door frame?
Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself.
