What happens if it’s left?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job and needn’t wait for anything else. For landlords in St Marys, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

How we handle fire rated sealant in St Marys
Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That is the part we focus on, one gap at a time. If you’re dealing with gaps where walls meet ceilings or slabs and old fire sealant that has split or come away, we can help, on pipe & cable gaps, plasterboard & masonry and flats & HMOs alike.
Scotland’s cities have offices, hotels, student flats, care homes and tenement blocks looked after by factors. For a building in St Marys, the job might be washroom resealing or fire-rated sealant around service openings.
The work is covered for a year after we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

Aftercare tips
A little care helps the new joints last. We recommend:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Include hidden areas like risers in routine checks
- Take pictures of fire stopping before ceilings or boxing go back
- Check whether a sealant can be painted before decorating over it
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. Inside a flat in St Marys, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.

What affects the cost of fire rated sealant
There’s no set price list, because jobs vary so much. What we look at:
- The number of rooms or windows
- Any working-time requirements on site
- Whether there’s mould to deal with
- The type of sealant required
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- The type of property
- Photos by email, if that is easy
- Access, such as stairs, a lift or height
- The rough size of the job
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What the job involves on each surface
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details.
Flats and HMOs
Conversions generally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and the locations noted.
Common problems we fix in St Marys
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.
If you can see any of these, it’s time to have the joints looked at:
- New service routes left unsealed after building work
- Old fire sealant that has split or come away
- Ordinary sealant used where a fire-rated product was needed
- Open joints along the top of partitions
If you let a flat or house near Invergowrie station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
