About our facade sealing in Lochwinnoch
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. If you’re dealing with discoloured or dirty facade joints and patch repairs that keep failing, we can put it right. Facilities teams, main contractors and managing agents in Lochwinnoch tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Lochwinnoch that means watching the forecast. We build some give into the plan and agree it with the site manager.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

- Access details, including height

Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For work around Lochwinnoch, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.
Before we start on site
- Let us know about inductions and permits
- Clear stock, furniture or equipment away from the joints
- Let building users know which areas are affected

Advice
Why deal with it now?
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. For buildings near Lochwinnoch, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
Why clients in Lochwinnoch choose us
- Products installed to the manufacturer’s instructions
- Matching to RAL references, product permitting
- A fixed quote before work starts
- Old sealant cut out, never sealed over

Mastic packages on Lochwinnoch sites
Scotland has its own building regulations, and in Lochwinnoch warrants come from the local authority verifier. The mastic package follows the approved specification. The west of Scotland, where Lochwinnoch is, gets more rain than the east. External mastic dates are agreed with the site manager, with internal sealant kept ready for wet days.
Sites around Lochwinnoch get mastic sealed to the drawings and the programme, nothing improvised. New wings at hospitals like Merchiston Hospital (to the north-east of Lochwinnoch) bring long runs of window and panel joints to seal.

Aftercare for building managers
After handover, these steps help:
- Avoid patch repairs on failed facade joints
- Clear debris that holds water against joints
- Note when each elevation was last resealed
- Add perimeter sealant to planned maintenance checks
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and work stops until it’s tested if it’s suspected.
Your questions answered
Would you work within a site like Merchiston Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Lochwinnoch too far out for you?
Not at all: smaller places are covered as well as towns. Every Scottish council area is within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you replace windows or glass?
No. A glazing contractor handles that. What we seal are the joints around frames and panels on commercial buildings.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Can you find out why a window is leaking?
Yes. Photos help, and you can give us a call on 01277 525 020 or send photos by email to arrange a visit. Many frame leaks are sealant failures, though not all, and we will be honest about which it is.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
