How we quote for sand mastic

We do not publish a price list, because no two jobs are the same. The quote depends on:

  • Whether old sealant or filler has to be cut out
  • Whether there’s mould to deal with
  • Working hours on commercial sites
  • The type of sealant required

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 will know the price before we begin.

What to tell us for a quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • The type of property
  • How we’d reach the joints
  • The rough size of the job
  • A few photos by email, if you can

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.

Sand mastic in Guildtown

If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on brick reveals, stone surrounds and period & listed homes, and people most often call us about a silicone bead on a sash window that spoils the look and weathered mastic on the most exposed windows.

In and around a place like Guildtown, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

I rent my home. Can I book you?

Can I do it myself?

Can sand mastic be painted?

Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.

Why it’s worth doing now in Guildtown

Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in and new mastic seals them. In a place like Guildtown, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

Doing several joints on one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.

What sand mastic looks like in Guildtown

Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.

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

How it works

We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job normally takes anything from a few hours to a full day, depending on how many windows. Outside jobs in Guildtown need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.

  1. We start by checking each surround and agreeing the joints to renew.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. We pack any deep gaps so the mastic sits at the right depth.
  4. The mastic is mixed, pressed into the joint by hand and shaped.
  5. We dress the surface so it sits neatly against the masonry.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • Keep children and pets away from the work area
  • Let us know about earlier repairs to the joints

What we can’t put right

In fairness, there are a few things sealant will not fix:

  • Decayed frames that need repair
  • Damaged stone surrounds
  • Planning or listed building consent (your local planning authority decides)

If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.

Surfaces we seal

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

What the job involves on each surface

Timber door frames

Sand mastic is used round timber door frames too. We renew it the same way as on windows.

Stone surrounds

The stone is treated with care while raking out the old mastic.

What we’re called out for in Guildtown

Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.

Common reasons people contact us include:

  • Wind and rain getting in round a sash window
  • Window mastic to renew ahead of painting
  • Mastic dropping out of the joint
  • Open joints round the window box

In the older streets around Cambusmichael Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Aftercare tips

After the cure time, these simple habits help:

  • Keep sills and gutters clear so water drains away
  • Get any rot dealt with first
  • Leave the new mastic unpainted
  • 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.

Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
