Construction mastic in Old Pentland, done properly

External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal sealing often fills those days. We work on internal decorators’ caulk, cladding and panel joints and brick and block movement joints, and the failures we are asked to look at most are external joints sealed in damp or cold conditions that are now failing and caulk cracking where joints are moving more than expected. Looking for mastic applicators who cover Old Pentland? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Old Pentland that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Leave it or put it right?

Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple. Renewing every failing joint on one visit is the sensible approach for a place like Old Pentland. Photos of each area help us quote the whole job.

A quote for mastic packages depends on how many there are, their condition and the access. Ask us for a fixed quote.

Building and refurbishing in Old Pentland

Building work in Old Pentland comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. The mastic package follows the approved specification. Old Pentland is on Scotland’s drier eastern side. Frosty spells still affect external mastic dates. External mastic is planned with the site manager for workable conditions.

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. Older buildings in the area around Old Pentland, such as Melville Castle, 3.1 miles to the east of Old Pentland, need care when sealed: the product has to suit soft or historic materials. Recladding or extending a unit at a site like Straiton Retail Park, 0.6 miles to the south-east of Old Pentland, brings panel joints and frame perimeters into the programme.

Surface by surface

Window and door perimeters

A frame gap that’s too wide can’t just be filled with sealant. We check them during the first walk-round and flag any that need packing or adjusting before sealing starts.

Fire-rated sealant where specified

Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer; we work to the specification and the manufacturer’s installation guidance.

Building owners, agents and FMs in Old Pentland

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Advice

What sets the cost

Each job is priced on its own details. The main factors are:

  • Distance, for remote addresses
  • Access and working height
  • The product specified
  • Whether the work must be split into stages

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • The site address and postcode
  • Whether an asbestos survey exists
  • A wide shot and a close-up of the area
  • How the joints are reached, and at what height

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email the details over with what you know.

Looking after the joints

For the best life from the joints:

  • Note which sealant went where at handover
  • Protect sealed areas from following trades
  • Check frame gaps are within the sealant’s range before sealing
  • Allow flexibility for external sealing in damp or cold weather

If a joint is damaged after sealing, flag it early. We can return to clear snags before handover as agreed in the quote.

One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.

FAQs: Old Pentland

Can you work around term dates at a campus such as University of Edinburgh - Easter Bush Campus?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is Old Pentland off your patch?

No. Small places get the same service as large ones. Our area covers all of Scotland, cities, towns and islands alike. Where we can, we group nearby jobs to make the most of each trip.

How much does the work cost?

There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

How long does a typical visit take?

It depends on the scope, though a typical visit typically takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. Larger or phased jobs take longer, and we will give you a timescale with the quote.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Will you stick to the specified products?

The specification decides the product. Product standards such as BS EN 15651 are often named in specifications.
