Facade sealing in Hightae, done properly
Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. We work on shopfront frames, perimeter joints where frames meet the structure and cladding panel joints, and what we are called in for most is unsightly perimeter sealant on a visible elevation and patch repairs that keep failing. One point of contact handles commercial sealant work in Hightae from the first photographs to the final walk-round, for single jobs and planned programmes alike.
For a site around Hightae, we plan the mastic in as few trips as the programme allows. Clear drawings, a programme and photographs let us bring the right sealants, primers and backing rod first time.
A 12-month guarantee applies to all our work in Dumfries and Galloway. If an installation problem shows up, phone 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Facade sealing in Hightae: the local picture
Scotland has its own building regulations, and in Hightae warrants come from the local authority verifier. The mastic follows the specification that goes with the warrant. The east of Scotland, where Hightae is, gets less rain than the west. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. We programme around it with the site team.
For contractors building in or near Hightae, we seal to the drawings, the specification and the programme.

Common problems we fix in Hightae
When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.
It’s worth sending us details if you spot any of the following:
- Water coming in around window frames
- Previous reseals run over old sealant
- Discoloured or dirty facade joints
- Weathered joints at frame-to-structure perimeters
New wings at hospitals like Lochmaben Hospital (to the north-west of Hightae) bring long runs of window and panel joints to seal.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Do they follow the manufacturer’s priming guidance?
- Whether old or failed sealant will be cut out, not overlaid
Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Should maintenance staff do it?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Keep sills, gutters and drainage paths clear
- Brief window cleaners about newly sealed joints
- Record the product and colour used on each elevation
- Investigate damp beside windows promptly
Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal without guesswork.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.
Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Where we can, we combine work around Hightae with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.
- Access, site rules and timing are settled with the client up front.
- We only seal when joints are dry and within the product’s temperature range.
- We remove the old bead and check the edges are sound.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.

FAQs: Hightae
Is hospital work, at somewhere like Lochmaben Hospital, something you do?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you fit the mastic around our build programme in Hightae?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is it okay to overlay old mastic?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the faces are cleaned before resealing. That is what makes the new joint last.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How is access to upper-level joints handled?
That comes down to the access arranged for the job. Share what access exists or is planned when you send details.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Why deal with it now?
Topping up a failed joint typically buys very little time. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Hightae before they leak.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
