Lochgilphead Sand Mastic
Sand mastic for Lochgilphead, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Failed mastic on an exposed elevation

- A silicone bead on a sash window that spoils the look
Why deal with it now?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What you get with us
- Neat joints and a tidy finish
- Anti-fungal silicone where joints get wet
- We never seal over old sealant
- 20+ years of sealant experience

Sand mastic for homes and businesses in Lochgilphead
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. Common call-outs are for mastic dropping out of the joint and mastic round period door frames that has failed, across timber door frames, brick reveals and stone surrounds.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Common problems we fix in Lochgilphead
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Most people get in touch after spotting something like this:
- Draughty sash windows at the surround
- Modern sealant on a period surround
- Mastic round period door frames that has failed
- Gaps between timber frames and stone or brick
For an older house near a landmark such as Christ Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What else we do in Lochgilphead
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Have rotten timber repaired before new mastic goes in
- Don’t run silicone over sand mastic
- Do not paint over the new mastic
- Check with your local planning authority if your home is listed
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. Outdoor work around Lochgilphead depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Tell us if parking is tricky
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules

Lochgilphead homes and the weather
Lochgilphead is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you look after a building such as Lochgilphead High School, its window and door frames need their mastic kept sound, just like a home’s.
