Why it’s worth doing now in Thorntonhall
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish. For buildings near Thorntonhall, dealing with all the failing joints at once saves return trips. Send photographs and we will quote for everything together.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What you get with us
- Commercial sealant work since 2005
- CHAS accredited
- Coloured sealants to suit the setting, where available
- Joints cleaned back to sound surfaces

From enquiry to sign-off
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. For work around Thorntonhall, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm 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
- Flag any permit to work we’ll need
- Tell us which areas need to stay in use

Advice
Your questions answered
Do you cover business parks and estates near Thorntonhall, such as GSO Business Park?
Yes, sites like GSO Business Park are within our area, along with the rest of Thorntonhall. Send details of the unit and the work through our quote form for a quick quote.
Will you take on a block within reach of Thorntonhall station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
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’ll confirm with the quote.
Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Different surfaces, different methods
Window and door perimeters on blocks
We normally work through a block’s windows in a planned order. How each joint is reached is agreed at quote stage.
Commercial and mixed-use buildings
Commercial occupiers typically stay open during the work, so we plan around them.
Frames, entrances and external joints in Thorntonhall
Being in the west of Scotland, Thorntonhall gets more rain than eastern areas. Frame mastic on weather-facing sides tends to fail first. Programmes allow for wet days.
For agents with blocks near Thorntonhall station (under half a mile south-west of Thorntonhall), a block-wide mastic programme deals with frames, balconies and entrances in one go. If your remit includes a building such as Duncanrig Secondary School, frame and door mastic can be programmed for the holidays. Historic properties like Pollok House (to the north-west of Thorntonhall) show the age of some local stock, where frame mastic must suit soft brick or stone.
