Doing it in-house
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
How we handle commercial sealant contractors in Sighthill
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors with sites in Sighthill. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. We work on kitchen worktops and splashbacks, external facade joints and window and door perimeters, and the failures we’re asked to look at most are greasy, split joints in a kitchen or tea point and smeared sealant across finishes from a rushed job. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Sighthill, that means joint design, primers and backing rod as standard.
On a typical commercial building in Sighthill, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
Sighthill is part of one of Scotland’s big cities, where offices, shops, hotels and restaurants sit close together. Shop units under tenements can bring the property factor into the picture when the work touches shared parts.
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.

Sealant on show in Sighthill’s commercial buildings
The west of Scotland, where Sighthill is, gets more rain than the east. We plan external joints for dry spells and keep internal work in reserve. The 3 miles around Sighthill take in at least three named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies.
For a retailer at a site such as St Rollox Business and Retail Park, less than half a mile to the north-east of Sighthill, the joints customers see are as much part of the fit-out as the shelving. Occupiers with premises at both St Rollox Business and Retail Park and Inner City Trading Estate could have the sealant at each handled under one quote.
Sighthill is about 1 mile east of Woodside, in Glasgow. Across the G21 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 171 places across Glasgow fall within our area, Sighthill among them.

What we are called out for in Sighthill
If only one face has lost its grip, that’s an adhesion failure. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.
These are often picked up first by site or facilities staff:
- Sanitary sealant that has gone black and patchy
- Messy, uneven beads from earlier work that let the building down
- Frame mastic that has hardened and come away from the wall
- Shrunken sealant along kitchen worktops and splashbacks
In hotels such as Cathedral House Hotel (0.7 miles south of Sighthill), refurbishments normally mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Surface by surface
Movement joints in walls and floors
Movement joints in walls and floors let the structure expand and contract. Failed seals let grit and water in, and the edges start to suffer. The joints are resealed using a sealant matched to the movement and any traffic.
Window and door perimeters
The perimeter joint between a frame and the structure keeps rain out of the reveal. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.
Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on 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. Work on a big city site in Scotland typically involves inductions and permits. Pass on the site’s contractor rules when you get in touch.
- You send photographs, drawings or a list of the joints and areas involved.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Site hours, access windows and the order of areas are agreed before we start.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
Before we start on site
- Share your working hours and any access restrictions
- Warn occupants and staff about the work
- Flag any permit to work we will need

Common questions from Sighthill clients
Can the sealant on our Sighthill premises match the finishes?
Yes, we can typically get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.
Will our hotel in Sighthill need to close for the work?
Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.
Which site documents can you send us?
We confirm documents at quote stage: RAMS, an insurance certificate and CSCS details are the usual requests. Every applicator holds a CSCS card.
What about asbestos in old mastic?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.
Is the old sealant taken out first?
Removal of the failed sealant is always part of the job. Laying new silicone on old gives it nothing to grip; the faces are then cleaned and prepared.
Do you work for facilities managers and managing agents?
Yes. A large share of our work comes through facilities managers, managing agents and landlords. We can work to your instruction process and site rules.
Do you cover Sighthill?
Yes. We take on work across Sighthill.

What else we do in Sighthill
Why deal with it now?
Leaving a failed joint rarely saves money. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below, and the bill then involves other trades. Resealing while only the sealant has failed keeps the job small. In a Scottish city, access often needs scaffold, permits or factor approval, so deal with all failing joints while access is up.
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.
