Common questions from Kirkton clients

Is Kirkton off your patch?

Not at all: smaller places are covered as well as towns. Our area covers all of Scotland, cities, towns and islands alike. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

We manage a building near Dumfries station. Can you help?

Yes. Blocks of any size are within what we do. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Can you plan resealing across several buildings?

We can. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

Is it fine to apply new sealant on top of old?

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

How long does a job like this take?

The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.

Mastic sealing in Kirkton

Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. We work on communal entrances and stairwells, external wall and movement joints and balcony and threshold joints, and the failures we are asked to look at most are no planned programme for sealant and open joints in brickwork or panels. Looking for mastic applicators who cover Kirkton? We have been sealing commercial buildings since 2005.

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

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

When to call us in Kirkton

The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

Things that usually lead to an enquiry:

  • Water getting in round frames after rain
  • Communal area joints that look neglected
  • Patchy repairs in mismatched sealant
  • Failed external movement joints

Buildings close to stations like Dumfries station (to the south of Kirkton) are often flats over shops, with frame mastic to keep sound.

Comparing quotes

  • How long is the guarantee, and what does it include?
  • Can the work be phased to keep areas open?
  • Do they follow the manufacturer’s priming guidance?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Frames, entrances and external joints in Kirkton

Kirkton is on Scotland’s drier eastern side. Cold mornings still limit when outside mastic can go on. We plan block programmes with some give for it

Student accommodation around universities such as Crichton University Campus, 4.6 miles to the south of Kirkton, is usually managed block by block, which suits a planned mastic programme. Landlords with units on estates such as Irongray Business Park (to the south-west of Kirkton) can bring frame, door and external mastic across several units into one programme.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Where we can, we combine work around Kirkton with other jobs nearby. Let us know if your dates have any give.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. A fixed quote follows, split by block or building if that suits you.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

Why it’s worth doing now in Kirkton

Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work and less choice about when. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Kirkton, a repair visit takes planning, so it’s better to act early.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What we can’t put right

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

  • Frames that are rotten, warped or broken
  • Masonry that has broken away beside the joint
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

If in doubt, phone 01277 525 020 or use the quote form and we will say what we think.

Surfaces we seal

  • Balcony and threshold joints
