Mastic sealing near New Monkland

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

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Glazing that needs replacing
  • Frames that are rotten, warped or broken
  • Water coming in from the roof or rainwater goods

If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.

Where we work in New Monkland

  • Window and door perimeters on blocks
  • Balcony and threshold joints
  • External wall and movement joints
  • Communal kitchens and washrooms
  • Shopfronts below residential blocks
  • Communal entrances and stairwells

Mastic sealing in New Monkland

Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow along with complaints. We work on external wall and movement joints, communal kitchens and washrooms and communal entrances and stairwells, and the usual reasons a site gets in touch are failed external movement joints and draught complaints from residents or tenants. One point of contact handles commercial sealant work in New Monkland from the first photos to the final walk-round, for single jobs and planned programmes alike.

Travel to smaller places like New Monkland is planned so several buildings can be done on one trip. Send addresses and photos for a quote covering the batch.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to call us in New Monkland

The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. We’ll tell you if the joint edges need repairing before resealing.

If one of these sounds familiar, it’s time for a closer look:

  • Patchy repairs in mismatched sealant
  • Brittle perimeter mastic across a building
  • No planned programme for sealant
  • Occupiers reporting cold air round windows

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

Before you book anyone

  • Their plan for phasing and protecting the area
  • The terms of the workmanship guarantee
  • How joint depth will be controlled
  • Will RAMS and insurance details be available?

How to choose a sealant contractor

Doing it in-house

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Keep a record of when each building was resealed
  • Share your contractor requirements early
  • Check the asbestos register before any old mastic is disturbed
  • Look at the sunniest and most exposed elevations first

Where a paintable product was specified, it can be painted after curing. Silicone normally can’t be painted, so keep decorators off it.

Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.

Your questions answered

Is New Monkland too far out for you?

No. Places such as New Monkland are covered as much as the big towns. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you cover business parks and estates near New Monkland, such as Upper Mill Street Industrial Estate?

Yes, sites like Upper Mill Street Industrial Estate are within our area, along with the rest of New Monkland. Send details of the unit and the work through our quote form for a quick quote.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

Can you quote from photos?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

Can you reseal a whole block or estate?

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

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

The east of Scotland, where New Monkland is, gets less rain than the west. External mastic still needs a dry joint and the right temperature, and winter mornings can be frosty. Block programmes are built with that in mind

Property owners at sites such as Upper Mill Street Industrial Estate (to the south of New Monkland) can have mastic renewed between lettings. Trustees of buildings like Parish Church can bring frame and external mastic into a planned maintenance list.

On site: what to expect

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. For work around New Monkland, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Confirm the product named in the specification
  • Tell us which areas need to stay in use
