How we handle construction mastic in Midlem
Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on sanitary and kitchen joints, internal decorators’ caulk and window and door perimeters, and what we’re called in for most is frame perimeters left unsealed or poorly sealed and caulk cracking where joints are moving more than expected. A single leaking joint is often how a building in Midlem first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Sites near smaller places like Midlem can mean longer travel, so the mastic is planned with as few trips as the job allows. Clear drawings, a programme and photos let us bring the right sealants, primers and backing rod first time.
Work we carry out in the Scottish Borders comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or use the quote form and we will arrange a return visit.

Advice
How the job changes by surface
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team.
External facade and movement joints
External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it, and seal only with a dry joint inside the product’s temperature range.
Quoting for work in Midlem
Your fixed quote is built from the real scope. It takes account of:
- Location, for remote and island sites
- Any access equipment needed
- Backing rod, priming and other preparation
- The product specified
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.
Details that help us quote
For an accurate fixed quote, we need a clear picture of the site. Send us:
- What the building is and how it’s used
- The asbestos register, for older buildings
- Your programme or deadline
- Any specification or named product
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or use the quote form if you’d rather talk the job through.
Common problems we fix in Midlem
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated.
Look out for the following:
- Different trades sealing to different standards
- Frame perimeters left unsealed or poorly sealed
- New external sealant already peeling away
- Cracks opening in caulked internal joints
For contractors building in or near Midlem, we seal to the drawings, the specification and the programme.
Questions to ask before you book
- Will failed sealant be removed rather than covered?
- Are they CHAS accredited or on Constructionline?
- How they handle RAMS and site documents
- How the joint faces will be prepared and primed
Site staff or a sealant specialist?
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.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Specifying the product where the designer hasn’t
- Damage to finishes by other trades after we have sealed
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
What we seal
- Cladding and panel joints

Building and refurbishing in Midlem
Scotland has its own building regulations, and in Midlem warrants come from the local authority verifier. Our job is to seal to that specification. The east of Scotland, where Midlem is, gets less rain than the west. Winter mornings can still bring frost and condensation on steel and glass. External mastic is planned with the site manager for workable conditions.
Extensions at sites like Dingleton Hospital (3.7 miles north of Midlem) normally sit beside working departments, and the mastic follows strict access rules.

Midlem: questions and answers
Is Midlem too small for you to travel to?
No. Places such as Midlem are covered as much as the big towns. We cover the whole of Scotland. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you keep pace with our programme in Midlem?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
What joints do you seal on a new build?
Window and door perimeters, internal decorators’ caulk where specified, sanitary joints, kitchens, movement joints and snagging. We price to the specification and drawings.
Does weather affect external mastic work?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Sealing in poor conditions risks adhesion failure, so we wait rather than redo work.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
