Keeping the joints sound
For the best life from the joints:
- Encourage occupiers to report problems at frames
- Check sealant joints during planned building inspections
- Track which buildings were done and when
- Start inspections with the most exposed faces
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
Mastic sealing for commercial buildings in Mochrum
Owners and agents usually inherit a building’s mastic rather than choose it, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow along with complaints. We work on shopfronts below residential blocks, communal kitchens and washrooms and balcony and threshold joints, and the failures we’re asked to look at most are window mastic that has split and shrunk and complaints coming in block by block. Facilities teams, main contractors and managing agents in Mochrum tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Outside mastic in Scotland needs dry joints and the right temperature, so work around Mochrum is planned with the forecast. Programmes allow for the weather.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

FAQs: Mochrum
Will you price a mastic programme across our Mochrum portfolio?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
Is Mochrum off your patch?
No. Places such as Mochrum are covered as much as the big towns. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.
How do you handle work on occupied blocks?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you need mastic sealing in Mochrum?
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
Site and facilities staff are often the first to spot these:
- Worn sealant at communal door frames
- The same joint failures repeated across a portfolio
- Water getting in round frames after rain
- Patchy repairs in mismatched sealant
Owners near Mochrum can renew frame and external mastic block by block on one programme.
Before you book anyone
- What level of public liability insurance do they hold?
- How they handle RAMS and site documents
- Whether their applicators hold CSCS cards
- Is depth set with backing rod, or bond-breaker tape in shallow joints?

Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Looking after buildings in and around Mochrum
Mochrum sits close to the coast, within about 2 miles. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, so it’s worth inspecting those sides more often. Being in the west of Scotland, Mochrum gets more rain than eastern areas. The most exposed elevations need checking most often. Outside mastic goes on in dry spells, with some flexibility in the programme.
If you’re responsible for a building such as Kirk of Mochrum, frame and door mastic needs the same attention as any other property.
