Mastic sealing for commercial buildings in Colston
Managing agents and housing associations usually need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. We work on window and door perimeters on blocks, shopfronts below residential blocks and external wall and movement joints, and what we are called in for most is mastic failing across several blocks on an estate and cracked, hardened mastic round windows on a block. A single leaking joint is often how a building in Colston first comes to us: we look at the rest while we’re there and tell you what we find.

Why deal with it now?
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Colston, a repair visit takes planning, so it’s better to act early.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
Why us?
- CSCS-carded applicators
- Failed material removed, not covered up
- Fixed quotes based on photographs, drawings or a visit
- RAL and finish matching where the product range allows

FAQs: Colston
Is a smaller place like Colston outside your area?
No. Small places get the same service as large ones. Every Scottish council area is within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work at a site such as Balmore Industrial Estate, by Colston?
Yes. Our area takes in Colston and its surroundings, with estates and business parks such as Balmore Industrial Estate included. A few photos and the unit address let us price the work.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
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.
What do you charge?
There isn’t a price list, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Owners, agents and contractors
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Frames, entrances and external joints in Colston
Colston is in the west of Scotland, the wetter side of the country. Frame mastic on weather-facing sides tends to fail first. We plan block programmes with the forecast in mind.
Landlords with units on estates such as Balmore Industrial Estate (to the west of Colston) can bring frame, door and external mastic across several units into one programme. Older community buildings, Colston Wellpark Church among them, often have frames of mixed ages whose mastic varies.

How the job changes by surface
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos and the register is checked before anything is disturbed. Suspect material is tested before work continues.
Communal areas
Low-level communal joints get damaged more than most and tend to fail first.
How the quote is worked out
Each job is priced on its own details. The things that drive the figure:
- Whether old sealant has to be cut out first
- The product specified
- Working within restricted access windows
- Access and working height
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Whether an asbestos survey exists
- How the joints are reached, and at what height
- Drawings or a marked-up plan, if available
- The product your specification calls for
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
