Mastic sealing near Killochyett

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Maintenance after handover

To get the most from the new sealant:

  • Make it easy for occupiers to report draughts
  • Group repairs into a planned programme
  • Check sealant joints during planned building inspections
  • Track which buildings were done and when

Keep records of when each building was resealed. It helps plan the next round and gives you a history.

Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.

About our mastic sealing in Killochyett

Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. If you have failed external movement joints and draught complaints from residents or tenants, we can put it right, whatever the surface. For commercial sealant work in Killochyett, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

For buildings around Killochyett, we group the work to keep travel and visits down. A list of addresses and photographs lets us quote for them together.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Building owners, agents and FMs in Killochyett

CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Failed window or door frames, which need a window contractor
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Broken glass or failed sealed units

Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Joints and surfaces we work on

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

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building near Killochyett, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  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. Buildings are completed in turn.

Getting the site ready

  • Warn occupants and staff about the work
  • Have the specification and drawings to hand
  • Point out parking and an unloading spot

Questions about Killochyett

Do you work for managing agents with blocks near Stow station?

Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.

Is Killochyett too far out for you?

No. Small places get the same service as large ones. We work across every Scottish council area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How long does a typical visit take?

That varies with the scale of the job, but the work normally takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Do you need mastic sealing in Killochyett?

Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.

Clients typically get in touch after noticing one or more of the following:

  • Estate-wide sealant that is simply worn out

For agents with blocks near Stow station, under half a mile to the south of Killochyett, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Questions to ask before you book

  • How the joint faces will be prepared and primed
  • What site paperwork they can supply
  • How the existing material will be dealt with
  • How long is the guarantee, and what does it include?
