About our mastic sealing in Thornhill
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. If you have mastic failing across several blocks on an estate and water getting in round frames after rain, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Thornhill is the same: the right product in a properly prepared joint.
Around smaller places such as Thornhill, buildings managed by landlords and associations are often small groups of flats, sheltered housing and halls. Frames on exposed elevations are where mastic normally fails first.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Advice
Questions we’re asked in Thornhill
Can one quote cover a number of our buildings near Thornhill?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
Is a smaller place like Thornhill outside your area?
Not at all: smaller places are covered as well as towns. Our area covers all of Scotland, cities, towns and islands alike. Good photos up front let us bring everything on the first visit.
Can people stay in the building while you reseal?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Which sealant will you use?
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.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
What about access for upper-floor joints?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
Owners, agents and contractors
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.
Quoting for work in Thornhill
What shapes the price:
- The size and state of each joint
- Access and working height
- Whether old sealant has to be cut out first
- Site requirements such as inductions and permits
Pricing mastic joints depends on quantities, condition and access, and any specification that applies. Call for a quote.
What we need to price the job
Diagnosis starts before we arrive. Let us know:
- Access details, including height
- Photos of the joints, close up and from further back
- Any dates the work must fit around
- The asbestos register, for older buildings
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
After the work
Once the work is signed off, these steps help:
- Protect low-level joints in entrances
- Encourage occupiers to report problems at frames
- Plan resealing building by building rather than complaint by complaint
- Prioritise elevations facing the weather
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.

Why it’s worth doing now in Thornhill
Sealing over failed mastic looks tidy for a while. It doesn’t bond and typically fails within a short time. Full removal and proper preparation is what lasts. For buildings near Thornhill, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

When something else is needed
Being straight saves everyone time. New sealant won’t cure:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Leaks through the frame itself rather than the perimeter
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
If you’re not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
