Mastic sealing in Altens
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. We work on shopfronts below residential blocks, window and door perimeters on blocks and communal kitchens and washrooms, and what we are called in for most is estate-wide sealant that is simply worn out and draughts at frames across a block. Whoever orders the work in Altens, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
In Scotland’s cities, housing associations look after blocks and estates of every age. Planned mastic programmes can renew frame and external joints block by block.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

When to call us in Altens
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Look out for the following:
- Failed external movement joints
- Patchy repairs in mismatched sealant
- Communal area joints that look neglected
- Damp patches beside frames
Blocks of flats and mixed-use buildings often cluster around stations such as Aberdeen station, 2.1 miles to the north of Altens, and their window and balcony mastic tends to age at the same rate across a building.
Questions to ask before you book
- What the guarantee covers, and for how long
- How the joint faces will be prepared and primed
- Their public liability cover
- How the existing material will be dealt with
When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Failed window or door frames, which need a window contractor
- Glazing that needs replacing
- Leaks from above rather than through a joint
If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think before you book.

Leave it or put it right?
Dealing with failed joints one report at a time is slow and scattered. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Scottish city buildings take plenty of rain, so a split or hardened joint lets water into the wall. Renewing them early protects the fabric.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Keep bins and bikes away from communal door frames
- Group repairs into a planned programme
- Keep a record of when each building was resealed
- Prioritise elevations facing the weather
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.
Altens: questions and answers
Who arranges mastic work on a tenement in Altens?
In most tenements, the owners agree shared repairs, and many use a property factor to arrange them. Send details and photographs, and we will quote to whoever is arranging it.
Do you cover business parks and estates near Altens, such as Altens Industrial Estate?
Yes. We cover Altens and the area around it, including industrial estates, business parks and retail parks such as Altens Industrial Estate. Photos and a short description are enough for a first look.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you work in Altens?
Yes. We take on work across Altens, and the same phone number covers every area.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
On site: what to expect
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. City jobs in Altens normally need parking and loading planned. Shared closes, stairs and the property factor may need to be part of the plan.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Have the specification and drawings to hand
- Share your working hours and any access restrictions

Advice
For owners and agents in Altens
The sea is no more than about 1 mile from Altens. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. The east of Scotland, where Altens is, gets less rain than the west. External mastic still needs a dry joint and the right temperature, and winter mornings can be frosty. Block programmes are built with that in mind
Churches, halls and community buildings such as Nigg Parish Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. If your remit includes a building such as Lochside Academy, frame and door mastic can be programmed for the holidays.
