Mastic sealing for Portessie sites

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

Why act early in Portessie

Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows and occupiers notice. For buildings near Portessie, dealing with all the failing joints at once saves return trips. Send photos and we will quote for everything together.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Mastic sealing in Portessie

Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. The enquiries we see most involve mastic failing across several blocks on an estate and water getting in round frames after rain, across shopfronts below residential blocks, window and door perimeters on blocks and communal entrances and stairwells. A specialist sealant contractor works differently from a general builder: in Portessie, that means joint design, primers and backing rod as standard.

Travel to smaller places like Portessie is planned so several buildings can be done on one trip. A list of addresses and photographs lets us quote for them together.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Common questions from Portessie clients

Is a smaller place like Portessie outside your area?

Not at all. Portessie is within our area. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.

Does a coastal location like Portessie affect which sealant is used?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Can you plan resealing across several buildings?

We can. We survey and price each building, then work through them in order starting wherever is most urgent.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

What do you charge?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.

Will residents or tenants be disturbed?

We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.

Site staff or a sealant specialist?

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.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Planned mastic for Portessie portfolios

The sea is no more than about 1 mile from Portessie. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. The east of Scotland, where Portessie is, gets less rain than the west. Outside mastic still waits for dry, frost-clear conditions. We plan block programmes with some give for it

If you are responsible for a building such as St Peter's Church and Old Burial-Ground, frame and door mastic needs the same attention as any other property. Property owners at sites such as March Road Industrial Estate, 0.5 miles to the south of Portessie, can have mastic renewed between lettings.

Portessie is about 1 mile north-east of Buckie, in Moray. We cover commercial sites throughout Portessie, whether it’s a single job or part of a planned programme. We work across 59 places in Moray, large and small. For work in that direction, see our Aberdeen page, about 48 miles away.

Advice

Common problems we fix in Portessie

UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.

It’s worth sending us details if you spot any of the following:

  • Occupiers reporting cold air round windows
  • No planned programme for sealant
  • Patchy repairs in mismatched sealant
  • Window mastic that has split and shrunk

If your remit includes a building such as Buckie High School, frame and door mastic can be programmed for the holidays.

What your quote should include

  • Is the sealant right for the movement and the substrate?
  • Their public liability cover
  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

Building owners, agents and FMs in Portessie

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

When you manage a building on behalf of an owner, 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.

Surface by surface

External movement joints

Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.

Communal areas

We keep entrances and stairs open throughout. We work in sections so access is never blocked.
