DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How we handle fire rated sealant in D'Arcy
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. If you are dealing with joints picked up in a fire-stopping survey and seals cut through by electricians, plumbers or data installers, we can put it right.
Work in a place like D'Arcy is planned ahead, journey included, so the job can fit around guests, residents or opening hours where possible.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere like D'Arcy may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Before we arrive
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit

Common problems we fix in D'Arcy
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
It’s worth asking for a quote if you see:
- Gaps flagged on a fire risk assessment
- Open gaps behind door architraves
- Damaged fire sealant left by other trades
- Fire seals that have cracked with movement
For site and facilities teams at buildings such as Newbattle Community High School, service openings in fire-resisting walls need checking after any refurbishment.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- Which colour the sealant will be
- How long the guarantee is
- Which sealant they’ll use, and why
Surface by surface
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Flats and HMOs
In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before any work starts to keep disruption down.
Why act early in D'Arcy
Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

Common questions in D'Arcy
Do you cover smaller places like D'Arcy?
Yes, D'Arcy is covered. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Newtongrange station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on how many gaps there are. Your quote will say how long we expect yours to take.
Is standard sealant good enough for a fire gap?
No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.
Do you certify the fire stopping?
We do not give ratings or certificates for our work. The requirement comes from your assessor, designer or building control, and we apply a product tested for it with a record of each location.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you do fire sealant around door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door, its seals and closer are for a door specialist.
