What we’re called out for in Bonkle

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

Look out for the following:

  • Window mastic that has split and shrunk
  • Complaints coming in block by block
  • A mix of products and colours from past repairs
  • Damp patches beside frames

If you are responsible for a building such as Bonkle Parish Church, frame and door mastic needs the same attention as any other property.

What to look for in a quote

  • Which product they’ll use, and why it suits the joint
  • Who will actually carry out the work
  • What site paperwork they can supply
  • Their pre-qualification and accreditations

How to choose a sealant contractor

Your questions answered

Do you take on block-wide or estate-wide mastic work in Bonkle?

Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.

Is Bonkle off your patch?

No. Small places get the same service as large ones. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.

When is resealing likely to be due?

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

Can you seal joints high up on a block?

Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we will tell you how we’d approach it.

Do you work with property factors and landlords?

We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.

How do you handle work on occupied blocks?

The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.

Is mastic sealing guaranteed?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

Cost factors for mastic joints

To price the job, we consider:

  • How accessible the joints are
  • The product specified
  • The site’s rules and procedures
  • Whether the work must be split into stages

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Before you send an enquiry

There’s no need for a formal survey. These details are enough to start:

  • How the joints are reached, and at what height
  • The asbestos register, for older buildings
  • Whether the building will be occupied during the work
  • Any dates the work must fit around

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or phone 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

When something else is needed

We check first that sealant really is the fix. It won’t put right:

  • Frames that are rotten, warped or broken
  • Materials that need asbestos testing before work
  • Misted or failed double-glazed units

If you’re not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer.

Surfaces we seal

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

Blocks and managed buildings in Bonkle

Bonkle is in the east of Scotland, which is drier than the west. External mastic still needs a dry joint and the right temperature, and winter mornings can be frosty.

Buildings close to stations like Hartwood station (to the north-east of Bonkle) are often flats over shops, with frame mastic to keep sound. If your remit includes a building such as Coltness High School, frame and door mastic can be programmed for the holidays.

Bonkle is about 3 miles east of Wishaw, in North Lanarkshire. If you’re looking for mastic sealing in Bonkle, we can help. Across North Lanarkshire, 100 places are covered, Bonkle among them. Sites around Glasgow have their own page, about 17 miles away.

Anyone looking for mastic sealing in ML2 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

If your building is just outside Bonkle, we cover Crindledyke (1 mile south-west), Allanton (1 mile north-east), Newmains (1 mile west), Morningside (1 mile south) and Chapel (1 mile south). Bigger towns within reach include Motherwell (5 miles west), Cumbernauld (12 miles north-west), Coatbridge (8 miles north-west), Airdrie (7 miles north-west), Wishaw (3 miles west) and Bellshill (7 miles west).

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Check sealant joints during planned building inspections
  • Share your contractor requirements early
  • Plan resealing building by building rather than complaint by complaint
  • Keep a record of when each building was resealed

Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.

Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For work around Bonkle, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Preparing the site

  • Make sure the joints can be reached
  • Agree which areas must stay open
  • Confirm the product named in the specification
