Leave it or put it right?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs. We’ll say so if a frame itself is the problem. Around smaller places like Dirleton, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Construction mastic in Dirleton
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility and gives you a consistent finish across the job. We work on window and door perimeters, cladding and panel joints and internal decorators’ caulk, and what we are called in for most is different trades sealing to different standards and failed sealant in an existing building being refurbished. Searching for sealant specialists in Dirleton? We have been sealing commercial buildings since 2005.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Dirleton that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common problems we fix in Dirleton
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
It’s worth sending us details if you spot any of the following:
- Caulk cracking where joints are moving more than expected
- Different trades sealing to different standards
- Failed sealant in an existing building being refurbished
- Early adhesion failures on new external joints
When a school such as North Berwick High School is extended or refurbished, the mastic package is often squeezed into the holidays.

Questions about Dirleton
Is Dirleton too small for you to travel to?
No. Small places get the same service as large ones. Every Scottish council area is within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Would you work within a site like Edington Cottage Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
How do you work with the site programme?
We work to your programme. Tell us the sequence and we’ll plan applicators around it so sealing follows the trades.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
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. Indoors, the weather is rarely a problem.
Building owners, agents and FMs in Dirleton
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm 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.
Cost factors for mastic packages
What shapes the price:
- Site requirements such as inductions and permits
- Location, for remote and island sites
- Phasing around occupants
- Removal of failed or old sealant
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Facades, frames and programmes in Dirleton
With the shore within about 2 miles, Dirleton counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Being in the east of Scotland, Dirleton gets less rain than the west coast. Cold, damp starts still stop external sealing on some days. We agree external dates with the site team and keep internal work ready.
Hospital estates such as Edington Cottage Hospital (to the east of Dirleton) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Dirleton is about 6 miles north of Haddington, in East Lothian. Across the EH39 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across East Lothian, 48 places are covered, Dirleton among them. For work in that direction, see our Edinburgh page (18 miles or so).

Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Record the products used in the O&M file
- Release areas for mastic once other trades have finished in them
- Keep scrapers and abrasive pads off new beads
- Put any product change through the designer first
Expect some settlement in the first months. The right product in each joint copes with that while rigid fillers and caulk can crack where movement is larger. We can advise if a joint needs a different product.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Holding off until conditions suit avoids callbacks, so we plan external work with that in mind.
