Mastic sealing in Dunragit
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on window and door perimeters on blocks, balcony and threshold joints and communal kitchens and washrooms, and the usual reasons a site gets in touch are repeated reactive repairs to the same buildings and water getting in round frames after rain. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Dunragit is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places such as Dunragit, buildings managed by landlords and associations are often small groups of flats, sheltered housing and halls. Exposed walls take Scottish weather hard, and frame mastic shows it first.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next.

- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Preparing the site
- Share your working hours and any access restrictions
- Point out any areas we must not close
- Let us know about inductions and permits
Request a quote
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
Advice
After the work
A few simple habits keep the new joints working:
- Avoid piecemeal callouts where you can
- Ask residents or tenants to report leaks and draughts early
- Track which buildings were done and when
- Reduce knocks to communal area joints
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.
Leave it or put it right?
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish and one 12-month guarantee. Around smaller places like Dunragit, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

FAQs: Dunragit
Can you quote for mastic across several buildings in and around Dunragit?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
Does a coastal location like Dunragit affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Can people stay in the building while you reseal?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
How long does a typical visit take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Do you cover Dunragit?
Yes. Sites across Dunragit are covered, with one number for every area we cover.
Can you send RAMS and CSCS details before starting?
We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
What we are called out for in Dunragit
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Site and facilities staff are often the first to spot these:
- Patchy repairs in mismatched sealant
- Movement joints with sealant missing
- Cracked, hardened mastic round windows on a block
- Communal area joints that look neglected
Owners near Dunragit can renew frame and external mastic block by block on one programme.

For owners and agents in Dunragit
With the shore within about 2 miles, Dunragit counts as a coastal location. On buildings near the shore, the side facing the weather normally needs its mastic renewed first; plan inspections around that. Dunragit is on Scotland’s wetter western side. The weather side of a block typically needs attention first. External work is booked for dry spells, with a little give in the dates.

What else we do in Dunragit
Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
