Leave it or put it right?
A quick bead over a damaged joint can get an area past inspection. New sealant laid on old or dirty sealant has nothing to bond to and the defect reappears in the defects period. Damaged joints are removed and resealed from clean faces. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

How we handle construction mastic in Thorntonhall
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. We work on brick and block movement joints, floor and skirting junctions and window and door perimeters, and what we are called in for most is different trades sealing to different standards and old sealant on a refurbishment that needs stripping before new work. Facilities teams, main contractors and managing agents in Thorntonhall tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In smaller places such as Thorntonhall, building work tends to be single schemes rather than big developments. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Honest limits
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Glazing units that are cracked or misted
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Joint design decisions that belong to the architect or engineer
If you’re not sure, just speak to us on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
What we seal
- Floor and skirting junctions
- Window and door perimeters
- Brick and block movement joints
- Cladding and panel joints
- Sanitary and kitchen joints
- Internal decorators’ caulk
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Don’t force external sealing on a damp or frosty day
- Ask installers to correct oversized gaps first
- Put any product change through the designer first
- Note which sealant went where at handover
Expect some settlement in the first months. Flexible sealants in the right joints handle normal movement while rigid fillers and caulk can crack where movement is larger. If that happens, let us know.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating, and a delay to handover. A check of every frame before decorators start is worth the time.
Sites and facades in and around Thorntonhall
A 2-mile radius around Thorntonhall takes in several hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. Being in the west of Scotland, Thorntonhall gets more rain than eastern areas. Outside mastic is booked around the forecast, and internal sealing fills the gaps.
Hotels like Busby Hotel, 1 mile to the north-west of Thorntonhall, rarely close for long, so refurbishment mastic is phased floor by floor. Further education sites such as Riverside Music College, 0.9 miles to the north-west of Thorntonhall, are extended and refurbished from time to time, with mastic often programmed into the summer break.

Common questions from Thorntonhall clients
Is Thorntonhall too far out for you?
Not at all. Thorntonhall is within our area. We cover the whole of Scotland. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will you take on work at estates like GSO Business Park, close to Thorntonhall?
Yes. Our area takes in Thorntonhall and its surroundings, with estates and business parks such as GSO Business Park included. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Do you offer coloured sealant?
That depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Can you quote from photos?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

What else we do in Thorntonhall
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Our process
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a building near Thorntonhall, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- First we take quantities off the drawings and read through the specification.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Every joint is prepared, set to depth and sealed with the specified product.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Before we start on site
- Have the specification and drawings to hand
- Share the asbestos register for older buildings
- Share your working hours and any access restrictions
Getting a fixed quote
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
Advice
What we’re called out for in Thorntonhall
A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.
Common reasons buildings call us in:
- Inconsistent sealant finishes from plot to plot
- Sealant knocked or painted over by other trades
- Window and door perimeters that won’t pass inspection
- Mastic snags holding up handover
Units on estates such as GSO Business Park (to the east of Thorntonhall) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Before you book anyone

- How joint depth will be controlled
- Do they follow the manufacturer’s priming guidance?
- Will failed sealant be removed rather than covered?
