Sand mastic near Ballantrae

Ballantrae: your questions answered

Can you do sand mastic in Ballantrae?

Yes. Our work covers the whole of Scotland, and Ballantrae is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.

Is Ballantrae within the area you cover?

Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you have insurance?

Yes. We are fully insured, and we have been doing sealant work for more than 20 years.

How long does the job take?

It depends on the size of the job, but as a guide it takes a few hours for a single window, longer for several. We will tell you when we quote.

What information do you need?

A short description and the location, with photos by email if possible. We’ll ask anything else we need to know.

Is consent needed for window work on a listed home?

It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.

Can new sealant go over the old?

No, because it fails. We remove every bit of old sealant first.

Will the old sealant be removed?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Sand mastic for homes and businesses in Ballantrae

Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. We are often asked to deal with open joints round the window box and window mastic to renew ahead of painting, on brick reveals, sash and case windows 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 one-year guarantee comes as standard, so you are covered after we’ve gone.

What happens if it’s left?

New sash windows are a major, costly change, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear quote for the lot.

Do you need sand mastic in Ballantrae?

Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.

Keep an eye out for these signs:

  • Old sand mastic that has cracked, crumbled or fallen out
  • Gaps where the frame meets the masonry
  • Mastic worn away on windows facing the weather
  • Cracked mastic round a front door frame

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

Questions to ask before booking

  • How the joint is cleaned and prepared
  • Are they insured?
  • What happens if they find a problem under the old sealant
  • Whether they seal over old material or remove it

How to choose a mastic man

Ballantrae homes and the weather

Ballantrae is close to 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 sound outside sealant is part of that.

Homes close to Ballantrae Parish Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Ballantrae is about 14 miles north of Stranraer, in South Ayrshire. Homes, rented property, offices and hotels in Ballantrae can book us for sand mastic, old or new, large or small.

Looking after it afterwards

Simple care keeps the joints in good condition. We recommend:

  • Find out about consent before window work on a listed home
  • Keep modern sealant off the mastic
  • Ask us before painting near the mastic
  • Clear gutters so water doesn’t pour onto the windows

When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.

An open joint round the box lets weather through. The longer it’s left, the more the joint opens.

Different surfaces, different methods

Tenement and terrace windows

Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.

Brick reveals

An open joint at a brick reveal lets weather in. Renewing the mastic closes it.

For landlords and businesses

We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.

In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.

What happens on the day

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours per window, depending on the condition of the joints. Around Ballantrae, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.

  1. We check the window surrounds and agree which joints need renewing.
  2. The loose and crumbling mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic isn’t too thick.
  4. Sand mastic is mixed and applied by hand, then shaped to the joint.
  5. We dress the surface so it sits neatly against the masonry.

Before we arrive

  • Let us know about earlier repairs to the joints
  • Tell us about any water getting in
  • On commercial sites, let us know about site rules
