Mastic sealing in Coalburn, done properly

In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on window and door perimeters on blocks, external wall and movement joints and shopfronts below residential blocks, and the usual reasons a site gets in touch are damp patches beside frames and movement joints with sealant missing. For commercial sealant work in Coalburn, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In smaller Scottish places like Coalburn, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Frames on exposed elevations are where mastic normally fails first.

A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or use the quote form and we’ll arrange a return visit.

Site staff or a sealant specialist?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

For owners and agents in Coalburn

The east of Scotland, where Coalburn is, gets less rain than the west. Cold mornings still limit when outside mastic can go on.

Landlords with units on estates such as Gateside Industrial Estate, 2.4 miles north of Coalburn, can bring frame, door and external mastic across several units into one programme.

On site: what to expect

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself normally taking anything from a day to a few weeks, depending on the number of buildings and joints. For a building near Coalburn, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Explain the parking and delivery arrangements
  • Confirm the product named in the specification

Advice

Questions we’re asked in Coalburn

Is Coalburn too far out for you?

No. Small places get the same service as large ones. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

Is Gateside Industrial Estate, near Coalburn, within your area?

Yes. Estates, retail parks and business parks around Coalburn, Gateside Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Do you guarantee the mastic work?

A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How much does the work cost?

Every job gets its own fixed quote. To get one, ring 01277 525 020 or email the details over with a description of the work.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
  • Leaks through the frame itself rather than the perimeter
  • Asbestos-containing sealant, which we don’t remove

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

Joints and surfaces we work on

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

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Keep bins and bikes away from communal door frames
  • Ask residents or tenants to report leaks and draughts early
  • Group repairs into a planned programme
  • Check the asbestos register before any old mastic is disturbed

Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.

Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.

Common problems we fix in Coalburn

Many failed joints were sealed without backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and it tears.

Site and facilities staff are often the first to spot these:

  • Complaints coming in block by block
  • Brittle perimeter mastic across a building
  • Communal area joints that look neglected
  • Movement joints with sealant missing

For owners and agents with buildings in or around Coalburn, block-wide mastic programmes deal with frames and external joints of the same age together.

Questions to ask before you book

  • Which product they’ll use, and why it suits the joint
  • Their approach to joint depth and backing
  • What level of public liability insurance do they hold?
  • Will RAMS and insurance details be available?
