Construction mastic around Gogar: points for this area
Gogar lies within about 3 miles of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Gogar is in the east of Scotland, which is drier than the west. Cold, damp starts still stop external sealing on some days. External mastic is planned with the site manager for workable conditions.
Further education sites such as Edinburgh College - Sighthill Campus, 1.7 miles south-east of Gogar, are extended and refurbished from time to time, with mastic often programmed into the summer break. Extensions at sites like Spire Murrayfield Hospital, 2.6 miles to the east of Gogar, normally sit beside working departments, and the mastic follows strict access rules. Hotels like DoubleTree by Hilton Hotel Edinburgh Airport (1.2 miles north-west of Gogar) rarely close for long, so refurbishment mastic is phased floor by floor.
Gogar is about 5 miles west of Edinburgh, in Edinburgh. Anywhere in EH12, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 174 places in Edinburgh.

How we handle construction mastic in Gogar
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. New and existing joints then get the same preparation. If you are dealing with sanitary sealant damaged by following trades and early adhesion failures on new external joints, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Gogar it comes down to the same thing: the right product in a properly prepared joint.
For a site around Gogar, we plan the mastic in as few trips as the programme allows. Send drawings, photos and the programme so everything needed arrives on the first day.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself usually taking a day or two on a small fit-out and several weeks on a large multi-storey package. For a building near Gogar, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.
- We price from the drawings, specification and programme you send.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Getting the site ready
- Send any specification or drawings in advance
- Warn occupants and staff about the work
- Point out parking and an unloading spot

How the job changes by surface
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.
Snagging before handover
Snags usually come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit, depending on what suits the programme.
What we can’t put right
We check first that sealant really is the fix. It won’t put right:
- Joints damaged after sign-off by following trades
- Approving fire stopping as compliant
- Oversized gaps that need packing or adjustment by others
Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly.
Where we work in Gogar
- Brick and block movement joints
- Window and door perimeters
- Sanitary and kitchen joints
- Cladding and panel joints
- Floor and skirting junctions
- Internal decorators’ caulk
Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Flag uneven or tapered frame gaps early
- Bring the mastic contractor in after the last trades are through
- Keep scrapers and abrasive pads off new beads
- Don’t force external sealing on a damp or frosty day
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating and possibly a delayed handover. A check of every frame before decorators start is worth the time.
FAQs: Gogar
Does the sea air around Gogar change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Is West Craigs Industrial Estate, near Gogar, within your area?
Yes. Estates, retail parks and business parks around Gogar, West Craigs Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Is the mastic package guaranteed?
Each package is backed by a 12-month guarantee. We carry five million pounds of public liability insurance.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can you seal external joints in wet or cold weather?
External mastic depends on conditions: the joint needs to be dry and within the product’s temperature range. We plan external elevations with that in mind.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
When to bring in a 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.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
What happens if it’s left?
Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area usually clears more for less disruption. We can run snagging as its own phase before handover. Around smaller places like Gogar, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
