Clarkston Sand Mastic
Problem with your window and door surrounds in Clarkston? We cut out the old, prepare the joints and apply the right sealant.
- Modern sealant on a period surround
- Mastic round period door frames that has failed
- Mastic dropping out of the joint
How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from a few hours to a full day, depending on how many windows. For a job in Clarkston, tell us where the work is, how to get in and where to park. Outdoor jobs need a dry day, so they can move if the weather turns.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Mention if the joints have been sealed before
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions

Advice
About our sand mastic in Clarkston
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. Common call-outs are for gaps where the frame meets the masonry and patchy fillers round a sash window, across sash and case windows, timber door frames and period & listed homes.
Wind and rain in a Scottish town like Clarkston find any gap around a frame. The windows facing the weather are normally the first to leak.
Whatever the size of the job, you get the same 12-month guarantee.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Crumbling stone or brickwork round the window
- Planning or listed building consent (your local planning authority decides)
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Keep sills and gutters clear so water drains away
- Take care around the mastic when scraping paint
- Ask us before painting near the mastic
- Look over the window mastic once a year
Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Sand mastic in Clarkston: local notes
The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out. Historic houses like Pollok House (about 3.5 miles north) are a reminder that the area around Clarkston has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Greenbank Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Clarkston station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Why deal with it now?
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Scottish weather finds any gap, and in a town like Clarkston, failed outside joints soon let damp into walls. Indoors, failed sealant lets water into floors and ceilings.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and give you a clear price before work begins.
