What affects the cost of sand mastic

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

  • The number of rooms or windows
  • The size of the job
  • Which sealant suits the joint
  • Whether there’s mould to deal with

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Helping us quote

What to tell us when you ask for a quote:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Any previous sealing or DIY work
  • Photos by email, if that is easy
  • How many joints, rooms or windows are involved

For sand mastic in Eastfield, email us at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.

Sand mastic in Eastfield

Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. If you are dealing with a silicone bead on a sash window that spoils the look and crumbling sand mastic round a window, we can put it right.

Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.

Each job carries a 12-month guarantee, whatever its size.

The process

Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a single window, longer for several. Outdoor work around Eastfield depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.

  1. We check each window surround and the condition of the joint.
  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

  • Mention any leaks or damp you’ve noticed
  • On commercial sites, let us know about site rules
  • Keep children and pets away from the work area

How to get a quote

Asking for a quote is easy: let us know what needs doing and where. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

Sand mastic in Eastfield: local notes

Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.

Around Eastfield, as everywhere, sand mastic is only as good as the preparation behind it.

What sealant work can’t fix

We’ll always be straight with you, so here’s what sealant cannot fix:

  • Rotten sashes, sills or window boxes (a joiner’s job)
  • Masonry that needs repairing
  • Putty and glazing repairs

If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.

Joints and surfaces we work on

  • Tenement windows
  • Timber door frames
  • Period & listed homes
  • Brick reveals
  • Sash and case windows
  • Stone surrounds

When to call us in Eastfield

Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.

Any of these means the joints need attention:

  • Modern sealant on a period surround
  • Mastic dropping out of the joint
  • Wind and rain getting in round a sash window
  • Patchy fillers round a sash window

If you let a flat or house near Blackridge station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

10 questions to ask before you book

Your questions about sand mastic in Eastfield

Can you do sand mastic in Eastfield?

Yes, Eastfield is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.

Will you come out to Eastfield?

Yes, Eastfield is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can tenants book the work?

Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

Is it messy?

Very little: the area around the joints is protected first, and we tidy up before we go.

Do you remove the old sealant?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Is it worth trying it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Is it possible to take out silicone and use sand mastic instead?

In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.

How long will you be here?

As a guide, most jobs take a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer.

For landlords and businesses

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

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.

Keeping the joints in good condition

Good habits help new joints last longer. A few tips:

  • Go gently near the mastic when preparing windows
  • Avoid patching sand mastic with silicone
  • Inspect the joints round the windows every year or so
  • Plan mastic work ahead of painting

Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.

Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.

Different surfaces, different methods

Tenement and terrace windows

Where a building is shared, window work may involve neighbours, so check who is responsible first.

Sash and case windows

Sash windows are where we do most sand mastic work. We renew the mastic round each box.
