Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Facade sealing in Old Pentland: the local picture

Being in the east of Scotland, Old Pentland gets less rain than the west coast. Frosty spells still affect external mastic dates. We programme around it with the site team. Scotland has its own building regulations, and in Old Pentland warrants come from the local authority verifier. We seal to the specification that sits behind the warrant.

New wings at hospitals like Ellen's Glen Community Hospital (2.2 miles north-east of Old Pentland) bring long runs of window and panel joints to seal. Projects at schools like Gracemount High School work to term dates, so mastic is programmed tightly. For contractors refurbishing units at places like Straiton Retail Park, 0.6 miles to the south-east of Old Pentland, the mastic covers cladding panels, roller-door and window perimeters.

Old Pentland is about 3 miles west of Bonnyrigg, in Midlothian. Across the EH20 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Midlothian coverage takes in 34 places, from busy centres to rural villages.

Facade sealing for commercial buildings in Old Pentland

A good facade joint depends on design as much as product. 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, often at around 2:1 width to depth, as the manufacturer advises. Site teams most often ask us about weathered joints at frame-to-structure perimeters and perimeter sealant that has split or peeled away, across coping and flashing joints, window and door perimeters and cladding panel joints. Whoever orders the work in Old Pentland, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Construction around smaller Scottish places like Old Pentland is often one-off schemes: a school, a health centre, a hotel extension or a few houses. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Commercial clients in Old Pentland

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Old Pentland. Several sites can go on one quote, which keeps the paperwork simple.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For a building near Old Pentland, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  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.

Getting the site ready

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

Ask for a quote

Related advice

Different surfaces, different methods

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them to the correct depth.

Coping and flashing joints

Sometimes the coping or flashing itself has failed. We tell you if the fix is a roofing or metalwork job rather than a reseal.

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Your questions answered

Do you take on work at healthcare sites like Ellen's Glen Community Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you plan work around the academic year at somewhere like University of Edinburgh - Easter Bush Campus?

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

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How do we ask for a quote?

The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

What type of sealant goes on window perimeters?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.

Should we check old sealant for asbestos?

In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first. Removal of asbestos isn’t something we do.

Leave it or put it right?

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Old Pentland, a repair visit takes planning, so it’s better to act early.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
