About our mastic sealing in Dolphinton
We diagnose before we prescribe: 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. Site teams most often ask us about water getting in round frames after rain and brittle perimeter mastic across a building, across window and door perimeters on blocks, external wall and movement joints and shopfronts below residential blocks. Most enquiries from Dolphinton start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Around Dolphinton, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
Every job we finish is backed by a 12-month workmanship guarantee, in Dolphinton as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What we’re called out for in Dolphinton
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Things that typically lead to an enquiry:
- Draught complaints from residents or tenants
- Patchy repairs in mismatched sealant
- Estate-wide sealant that is simply worn out
- Window mastic that has split and shrunk
For owners and agents with buildings in or around Dolphinton, block-wide mastic programmes deal with frames and external joints of the same age together.
What your quote should include
- Whether their applicators hold CSCS cards
- The terms of the workmanship guarantee
- Is the sealant right for the movement and the substrate?
- Their public liability cover

Advice
When to bring in a specialist
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

What the job involves on each surface
Communal areas
Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Fresh joints make shared areas look looked after.
External movement joints
The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.
Dolphinton: questions and answers
Can you quote for mastic across several buildings in and around Dolphinton?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
Is Dolphinton too far out for you?
Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Good photographs up front let us bring everything on the first visit.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
Can weather delay the job?
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. Indoors, the weather is rarely a problem.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
How long does a typical visit take?
It depends on the scope, but the work normally takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Check the asbestos register before any old mastic is disturbed
- Make mastic part of routine maintenance checks
- Track which buildings were done and when
- Group repairs into a planned programme
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
Honest limits
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Glazing that needs replacing
- Frames that are rotten, warped or broken
- Water coming in from the roof or rainwater goods
Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
Joints and surfaces we work on

Frames, entrances and external joints in Dolphinton
Being in the east of Scotland, Dolphinton gets less rain than the west coast. Outside mastic still waits for dry, frost-clear conditions. Programmes allow for that
Trustees of buildings like Dolphinton Parish Church And Churchyard can bring frame and external mastic into a planned maintenance list.
