About our facade sealing in Comiston
Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces. If you are dealing with water coming in around window frames and new sealant peeling off old mastic, we can help, on stone and brick facade joints, coping and flashing joints and cladding panel joints alike. One point of contact handles commercial sealant work in Comiston from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Around Comiston, city construction ranges from new offices, student housing and flats to the refurbishment of traditional stone buildings. Work comes under Scotland’s own building standards, and our job is to seal to the specification.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Surface by surface
Precast concrete panels
Joints between precast panels carry real movement. We use a sealant with the right movement capability, set over backing rod with primer where the product requires it.
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone.
Quoting for work in Comiston
These are the things that shape the price:
- Distance, for remote addresses
- Induction, permit and paperwork requirements
- Access and working height
- The size and state of each joint
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- The asbestos register, for older buildings
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
- Where the site is, with the postcode
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to ring 01277 525 020 or email the details over.
Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Give us the access times and building rules for your premises in Comiston, and we will plan the work to suit, phased where areas need to stay in use.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and both faces cleaned back.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Before we start on site
- Have the specification and drawings to hand
- Tell us which areas need to stay in use
- Tell staff and tenants when we will be in

Common questions from Comiston clients
Do you cover business parks and estates near Comiston, such as Blackford Business Park?
Yes. Estates, retail parks and business parks around Comiston, Blackford Business Park among them, are all within reach. A few photos and the unit address let us price the work.
Is hospital work, at somewhere like Royal Edinburgh Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you guarantee your work?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. That is what makes the new joint last.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
What happens if it’s left?
Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. In Comiston, as across Scotland, rain finds any gap, so a split or hardened joint lets water into the wall. Renewing them early protects the fabric.
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Building and refurbishing in Comiston
Being in the east of Scotland, Comiston gets less rain than the west coast. Winter mornings can still bring frost and condensation on steel and glass. We programme around it with the site team. There are a good number of hotels within about 2 miles of Comiston. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
For a contractor at a hotel such as Braid Hills Hotel, 0.5 miles north of Comiston, the mastic often has to be finished before a reopening date. For contractors at a school such as Firrhill High School, sealing has to be finished before term starts. University estates such as Edinburgh Napier University - Merchiston Campus (to the north of Comiston) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Plan facade sealing alongside redecoration
- Confirm the survey covers external sealants in older buildings
- Record the product and colour used on each elevation
- Check that rainwater leaves the facade the way it was designed to
Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
