When to call us in Dreghorn
Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant and the repair soon fails.
Most enquiries start with something like this:
- Cracked, hardened mastic round windows on a block
- No planned programme for sealant
- Failed external movement joints
- Leaks at window and door perimeters
For a school such as Greenwood Academy, perimeter mastic on windows and doors is a holiday job.

Mastic sealing for commercial buildings in Dreghorn
In buildings from before 2000, some old mastics contain 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. Site teams most often ask us about water getting in round frames after rain and movement joints with sealant missing, across communal kitchens and washrooms, communal entrances and stairwells and external wall and movement joints.

FAQs: Dreghorn
Our building in Dreghorn is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Will you take on work at estates like Heatherhouse Industrial Estate, close to Dreghorn?
Yes. Estates, retail parks and business parks around Dreghorn, Heatherhouse Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building near Dreghorn, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
What we need from you
- Arrange parking or a loading space
- Send asbestos survey details if the building is pre-2000
- Let building users know which areas are affected
Get a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Advice
When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Materials that need asbestos testing before work
- Broken glass or failed sealed units
- Leaks from above rather than through a joint
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly.

Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading, so we plan around them.
Frames, entrances and external joints in Dreghorn
Dreghorn lies within about 3 miles of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, so it’s worth inspecting those sides more often. The west of Scotland, where Dreghorn is, gets more rain than the east. Exposed elevations on blocks take a soaking and their mastic shows it. External work is booked for dry spells, with a little give in the dates.
With historic buildings such as Girgenti House (to the north of Dreghorn) in the wider area, owners of older properties around Dreghorn should expect mastic to need a product that suits old masonry. If you own or manage units on a site such as Heatherhouse Industrial Estate, 2.1 miles west of Dreghorn, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Why act early in Dreghorn
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Renewing every failing joint on one visit is the sensible approach for a place like Dreghorn. Photos of each area help us quote the whole job.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
