Mastic sealing in Hareshaw

Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. We work on external wall and movement joints, window and door perimeters on blocks and balcony and threshold joints, and the failures we’re asked to look at most are no planned programme for sealant and draught complaints from residents or tenants. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Hareshaw is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around Hareshaw, outside mastic waits for dry weather and the right temperature. Programmes allow for the weather.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Keeping the joints sound

After handover, a little attention goes a long way:

  • Reduce knocks to communal area joints
  • Share your contractor requirements early
  • Avoid piecemeal callouts where you can
  • Check the asbestos register before any old mastic is disturbed

If paintable sealant was used, decoration can follow once it has cured. Silicone normally can’t be painted, so keep decorators off it.

Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.

For owners and agents in Hareshaw

Hareshaw is in the east of Scotland, which is drier than the west. Outside mastic still waits for dry, frost-clear conditions. Programmes allow for that

Property owners at sites such as Newhouse Industrial Estate (to the west of Hareshaw) can have mastic renewed between lettings. Site managers at schools like Brannock High School can fit frame mastic into the summer works.

FAQs: Hareshaw

Is Hareshaw too far out for you?

Not at all. Hareshaw is within our area. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.

Can you quote for a block close to Cleland station?

Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.

Can weather delay the job?

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 does a job like this take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Is asbestos a concern with old mastic?

In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.

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.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Hareshaw can form part of a wider programme.

General trades versus a specialist

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Where we can, we combine work around Hareshaw with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Preparing the site

  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints

Common problems we fix in Hareshaw

UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.

Most enquiries start with one or more of the following:

  • Mastic failing across several blocks on an estate
  • Draught complaints from residents or tenants
  • Movement joints with sealant missing
  • A mix of products and colours from past repairs

If you look after a block within reach of Cleland station, 1.6 miles south of Hareshaw, frame and balcony mastic can be renewed on one programme.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • Their public liability cover
  • Their approach to joint depth and backing
  • What site paperwork they can supply

Questions to ask before you appoint anyone

Why deal with it now?

Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Hareshaw, a repair visit takes planning, so it’s better to act early.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

  • 12-month guarantee on workmanship
