FAQs: Lochmaben

Is Lochmaben too small for you to travel to?

No. Places such as Lochmaben are covered as much as the big towns. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.

Can you keep pace with our programme in Lochmaben?

Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Does the weather affect the work?

Outside, 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. Inside work is seldom held up.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

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.

Do you seal facades in winter?

Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

About our facade sealing in Lochmaben

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. The enquiries we see most involve failed seals around shopfront and entrance frames and patch repairs that keep failing, across coping and flashing joints, window and door perimeters and cladding panel joints. A single leaking joint is often how a building in Lochmaben 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.

Construction around smaller Scottish places like Lochmaben is often one-off schemes: a school, a health centre, a hotel extension or a few houses. The mastic still needs to suit exposed elevations and Scottish weather.

Every job we finish is backed by a 12-month workmanship guarantee, in Lochmaben as everywhere else we work. If our installation lets you down in that time, we return and fix it.

How a job runs

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. For work around Lochmaben, we aim for one trip, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Let building users know which areas are affected
  • Send your site hours and access windows

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Related advice

Why act early in Lochmaben

Topping up a failed joint typically buys very little time. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Lochmaben, 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, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Why appoint us

  • Work carried out by CSCS-carded applicators
  • Colours confirmed for the specified product
  • Standard and matched colours in many product ranges
  • Failed material removed, not covered up

See our cost guide or how we’re accredited.

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 any of the following:

  • Render or concrete edges that have broken away
  • Specialist high-level access methods
  • Joints whose design needs changing by the specifier

Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Where we work in Lochmaben

Different surfaces, different methods

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.

Window and door perimeters

Frame materials vary, and so does the preparation. We clean and prime to the sealant maker’s guidance for each surface.

General trades versus a specialist

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.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Facades, frames and programmes in Lochmaben

Projects in Lochmaben follow Scotland’s building regulations, with the local authority acting as verifier. The mastic package follows the approved specification. Being in the east of Scotland, Lochmaben gets less rain than the west coast. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. External mastic is planned with the site manager for workable conditions.
