When to call us in Lochdon
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Things that usually lead to an enquiry:
- Estate-wide sealant that is simply worn out
- Worn sealant at communal door frames
- Cracked, hardened mastic round windows on a block
- Open joints in brickwork or panels
For owners and agents with buildings in or around Lochdon, block-wide mastic programmes deal with frames and external joints of the same age together.
What your quote should include
- Will failed sealant be removed rather than covered?
- Who will actually carry out the work
- Which product they’ll use, and why it suits the joint
- Their plan for phasing and protecting the area
Mastic sealing for commercial buildings in Lochdon
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. If you have patchy repairs in mismatched sealant and cracked, hardened mastic round windows on a block, we can help. Facilities teams, main contractors and managing agents in Lochdon 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 Lochdon is planned with the forecast. We agree a window with some flexibility.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Common questions from Lochdon clients
Is Lochdon too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Good photos up front let us bring everything on the first visit.
Can you quote for mastic across several buildings in and around Lochdon?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. If any flats or units need access, we will tell you in advance so it can be arranged.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Make mastic part of routine maintenance checks
- List the paperwork your organisation requires when you send details
- Check the asbestos register before any old mastic is disturbed
- Track which buildings were done and when
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
On site: what to expect
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. For work around Lochdon, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
What we need from you
- Tell us which areas need to stay in use
- Flag any permit to work we’ll need
- Move anything stored against the joints
Ask for a quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email the details over with what you know.
Advice
Should maintenance staff do it?
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, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Leave it or put it right?
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Lochdon, a repair visit takes planning, so it’s better to act early.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

How the job changes by surface
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading, so we plan around them.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Planned mastic for Lochdon portfolios
Lochdon sits close to the coast, within about 1 mile. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. The west of Scotland, where Lochdon is, gets more rain than the east. Exposed elevations on blocks take a soaking and their mastic shows it. External work is booked for dry spells, with a little give in the dates.
For a building around Lochdon, a look at every elevation first shows which joints need renewing now and which can wait.
