DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the 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.
Fire rated sealant in Dolphinton
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, gap by gap. If you are dealing with open gaps behind door architraves and damaged fire sealant left by other trades, we can put it right.
For a place like Dolphinton, the journey and timings are planned in advance, so it can be fitted around bookings or opening times where possible.
Whatever the size of the job, you get the same one-year guarantee in Dolphinton and across the Scottish Borders.

What else we do in Dolphinton
Fire rated sealant around Dolphinton
Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details; we don’t certify buildings or carry out fire risk assessments.
In and around Dolphinton, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint. Community buildings like Dolphinton Parish Church And Churchyard are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Why deal with it now?
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Around Dolphinton, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Check risers, ceiling voids and cupboards during building checks
- Never patch a fire seal with standard sealant
- Flag any open gap you spot round a pipe or cable
- Photograph sealed gaps before they’re covered up
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the job gets bigger.
Landlords, agents and businesses in Dolphinton
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
How the job changes by surface
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details so the architrave can be refitted.
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Dolphinton may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
