How we handle mastic sealing in Acharn
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. We work on window and door perimeters on blocks, communal kitchens and washrooms and balcony and threshold joints, and the failures we are asked to look at most are damaged joints in communal entrances and corridors and draught complaints from residents or tenants. Searching for sealant specialists in Acharn? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Outside mastic in Scotland needs dry joints and the right temperature, so work around Acharn is planned with the forecast. We agree a window with some flexibility.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Your questions answered
Will you price a mastic programme across our Acharn portfolio?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
Which documents can you supply for work in Acharn?
RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Masonry that has broken away beside the joint
- Misted or failed double-glazed units
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
Surfaces we seal
- Balcony and threshold joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
- Shopfronts below residential blocks
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Look at the sunniest and most exposed elevations first
- Ask residents or tenants to report leaks and draughts early
- Group repairs into a planned programme
- Log resealing dates block by block
If paintable sealant was used, decoration can follow once it has cured. Silicone usually can’t be painted, so keep decorators off it unless told otherwise.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing.

What else we do in Acharn
For owners and agents in Acharn
Being in the west of Scotland, Acharn gets more rain than eastern areas. Exposed elevations on blocks take a soaking and their mastic shows it. Programmes allow for wet days.
Churches, halls and community buildings such as Kenmore 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. For owners and agents with buildings in or around Acharn, block-wide mastic programmes deal with frames and external joints of the same age together.
