What happens on the day

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. Somewhere like Kirkcolm may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.

  1. Each surround is checked first.
  2. The joint is raked out and cleaned.
  3. Large voids are packed out.
  4. We point the joint with sand mastic by hand.
  5. We finish the mastic to a tidy line.

Sand mastic in Kirkcolm, done properly

A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. Common call-outs are for mastic that needs renewing before redecorating and weathered mastic on the most exposed windows, on stone surrounds, brick reveals and timber door frames.

Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.

A 12-month guarantee comes as standard.

Should I try it myself first?

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

How we quote for sand mastic

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Access and height
  • The size of the job
  • Whether there’s mould to deal with
  • Whether old sealant or filler has to be cut out

Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.

What to tell us for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Any previous sealing or DIY work
  • The problem you’ve noticed
  • Pictures of the joints, sent by email
  • If it’s domestic, commercial or a hotel

We quote each job on its own, so start by telling us what you need. Just email us at info@mrmastic.co.uk with the details.

When something else is needed

We won’t take on work that won’t last, so these are the limits:

  • Cracked or broken glass
  • Whether work needs listed building consent
  • Timber that has rotted

If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.

Where we work in Kirkcolm

Why act early in Kirkcolm

Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In a place like Kirkcolm, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

Combining jobs into one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.

Do you need sand mastic in Kirkcolm?

Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.

Any of these means the joints need attention:

  • Silicone on a period window that looks wrong
  • Gaps between timber frames and stone or brick
  • Draughts and rain around sash boxes
  • Cement or filler used on old window joints that has cracked

In and around Kirkcolm, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Questions from Kirkcolm

Do you work for landlords with property near Stranraer station?

Yes, we work for landlords and letting agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.

Does living near the coast affect sand mastic in Kirkcolm?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Where do you work from?

We work from Crawley. Our applicators cover Kirkcolm.

How long does sand mastic take to go off?

It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

What information do you need?

The location, the problem and the rough size of the job. If you can, email a few photos.

Do I need to be at home?

Access is agreed with you when the job is booked. Indoors, that generally means someone at home.

Which products do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.

Kirkcolm homes and the weather

Kirkcolm is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.

If you let a flat or house near Stranraer station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Avoid heavy scraping on the mastic joint
  • Leave the new mastic unpainted
  • Make sure water runs off the sill
  • Ask the planning authority about consent for listed or conservation-area homes

Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.

Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
