Sand mastic in Aberlemno

Sand mastic in Aberlemno

Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead and we will explain which is best for yours. If you have cement or filler used on old window joints that has cracked and mastic that needs renewing before redecorating, we can put it right, whatever the surface.

Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.

Our work is backed for twelve months.

When it isn’t the sealant

We will not take on work that will not last, so here’s what sealant cannot put right:

  • Sash cords, weights and draught-proofing of the sashes
  • Putty and glazing repairs
  • Planning or listed building consent (your local planning authority decides)

Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

Quotes for sand mastic in Aberlemno

For a quick quote, just ask. The main things that affect it are:

  • Any mould that needs treating
  • How easy the joints are to reach
  • When we can work, for business premises
  • The type of sealant required

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Asking for a quote

To help us quote quickly, let us know:

  • What’s wrong with the joints now
  • Photos by email, if that’s easy
  • Where the property is
  • If it’s domestic, commercial or a hotel

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, email us at info@mrmastic.co.uk.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

How it works

We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a single window, longer for several. Outside jobs in Aberlemno need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.

  1. Each surround is checked first.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic is not too thick.
  4. New sand mastic is applied and shaped by hand.
  5. We finish the mastic to a tidy line.

How to prepare

  • Keep children and pets away from the work area
  • For business premises, tell us about site rules or sign-in
  • Tell us about access, such as stairs, a lift or high-level joints

What the job involves on each surface

Timber door frames

Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.

Sash and case windows

A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.

Aberlemno homes and 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. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.

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

Aberlemno questions

Is Aberlemno within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.

What guarantee comes with sand mastic in Aberlemno?

Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

How long does sand mastic take to go off?

It forms a skin fairly soon and it hardens fully over a longer time. The weather and joint depth both affect it.

Is sand mastic better than silicone for my windows?

We will help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.

How long does the job take?

Most jobs take a few hours for a single window, longer for several, including preparation and clearing up. Your quote will say how long we expect yours to take.

Is there any odour?

That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Can you seal over the old sealant?

No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Are you insured?

Yes. Full insurance covers our work.

When to call us in Aberlemno

Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.

These are the problems we are asked about most:

  • Mastic dropping out of the joint
  • Wind and rain getting in round a sash window
  • Open joints round the window box
  • Mastic round period door frames that has failed

For an older house near a landmark such as Aberlemno Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Our hiring checklist

How to look after the new joints

After the cure time, these simple habits help:

  • Ask a joiner to look at soft timber first
  • Leave the new mastic unpainted
  • Keep sills and gutters clear so water drains away
  • Check the mastic when you check the paintwork

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

Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
