Advice
Mastic sealing in Dunbar, done properly
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. Most enquiries involve old repairs sealed over failed mastic and window mastic that has split and shrunk, across communal entrances and stairwells, shopfronts below residential blocks and external wall and movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Dunbar is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places such as Dunbar, buildings managed by landlords and associations are often small groups of flats, sheltered housing and halls. Frames on exposed elevations are where mastic usually fails first.
A 12-month guarantee applies to all our work in East Lothian. If an installation problem shows up, phone 01277 525 020 or send details through our quote form and we will arrange a return visit.

Maintenance after handover
Your facilities or cleaning team can help the joints last. Share these points with them:
- Start inspections with the most exposed faces
- Make mastic part of routine maintenance checks
- Plan resealing building by building rather than complaint by complaint
- Mention RAMS, insurance or CSCS requirements up front
Keep records of when each building was resealed. It helps plan the next round and gives you a history.
Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Quoting for work in Dunbar
Your fixed quote is built from the real scope. It takes account of:
- Any access equipment needed
- Site requirements such as inductions and permits
- Quantities, in metres or numbers
- Working within restricted access windows
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What to include in your enquiry
We can often quote from photos and a few details. It helps to include:
- The asbestos register, for older buildings
- Drawings or a marked-up plan, if available
- Anything awkward about access or site hours
- Specification clauses that apply
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or email drawings and photos to discuss it first.
When something else is needed
Some faults sit outside our scope, and we say so rather than covering them up:
- Materials that need asbestos testing before work
- Frames that are rotten, warped or broken
- Water coming in from the roof or rainwater goods
Not sure which it is? You can call 01277 525 020 or use the quote form and we will tell you honestly.
What we seal
- Communal entrances and stairwells
- Balcony and threshold joints
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- External wall and movement joints
- Communal kitchens and washrooms
Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Signs you need mastic sealing in Dunbar
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.
Most enquiries start with one or more of the following:
- Failed external movement joints
- Window mastic that has split and shrunk
- Damp patches beside frames
- Communal area joints that look neglected
Trustees of buildings like Abbey Church of Scotland can bring frame and external mastic into a planned maintenance list.

- Which product they’ll use, and why it suits the joint
- How the joint faces will be prepared and primed

Dunbar: questions and answers
We manage a building near Dunbar station. Can you help?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Can you work at a site such as Spott Road Industrial Estate, by Dunbar?
Yes. Estates, retail parks and business parks around Dunbar, Spott Road Industrial Estate among them, are all within reach. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you seal joints high up on a block?
It depends on the building. We agree access with you at quote stage so there are no surprises.
Can you plan resealing across several buildings?
We can. We survey and price each building, then work through them in order starting wherever is most urgent.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.
