Common questions from Mossblown clients

Is Mossblown too far out for you?

No. Places such as Mossblown are covered as much as the big 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.

Can you work around term dates at a campus such as University of the West of Scotland - Ayr Campus?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can you quote from photographs?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.

Do you offer coloured sealant?

It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Do you provide access for facade work?

That varies with the building and the access on offer. Share what access exists or is planned when you send details, and we will agree the approach together.

Do we need an asbestos check before resealing?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, and we’ll ask to see it. If asbestos is suspected, work stops until it is tested.

Facade sealing for commercial buildings in Mossblown

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure for clients around Mossblown. Where sealant is the specified fix, we also take on coping and flashing joints. If you are dealing with leaks at window and door perimeters and weathered facade joints that have lost their grip, we can put it right, whatever the surface. Looking for mastic applicators who cover Mossblown? We have been sealing commercial buildings since 2005.

In smaller places such as Mossblown, building work tends to be single schemes rather than big developments. The mastic still needs to suit exposed elevations and Scottish weather.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Surface by surface

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone, and primers go on where specified.

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. For a building near Mossblown, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Share the asbestos register for older buildings
  • Tell staff and tenants when we will be in
  • Move anything stored against the joints

What happens if it’s left?

Failed joints let in more than water: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Mossblown, a repair visit takes planning, so it’s better to act early.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Do you need facade sealing in Mossblown?

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and rips when the facade moves.

Clients normally get in touch after noticing one or more of the following:

  • Cladding panel joints that have opened up
  • Draughts around frames and panels
  • Patch repairs that keep failing
  • Old perimeter mastic that has dried out

On a healthcare site such as Biggart Hospital, 3 miles west of Mossblown, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

How to choose a sealant contractor

Looking after the joints

For the best life from the joints:

  • Combine resealing with other works that need access
  • Keep pressure washers away from fresh sealant
  • Insist on a full cut-out when joints are renewed
  • Walk the elevations once or twice a year

Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade instead of soaking the joints.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.
