Questions from Mossend
Will you come out to Mossend?
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.
Do you work for landlords with property near West Calder station?
Yes, we work for landlords and agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can I choose the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What guarantee comes with the work?
There’s a 12-month guarantee on every job, sand mastic included.
How long does the job take?
Most jobs take a few hours for a single window, longer for several. We will confirm how long when we quote.
About our sand mastic in Mossend
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. If you’re dealing with gaps round a timber door in stone or brick and mastic dropping out of the joint, we can help, on sash and case windows, tenement windows and brick reveals alike.
Mastic can only go onto a dry joint, so outside work in Mossend depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
You get a 12-month guarantee, the same in Mossend as everywhere else we work.

What happens if it’s left?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. In an older home around Mossend, damp from a failed joint can get into timber and plaster.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Why us?
- Anti-fungal sanitary silicone in wet areas
- 12-month guarantee on every job
- Domestic, commercial and hotel work
- We leave the area clean and tidy
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Make sure water runs off the sill
- Have rotten timber repaired before new mastic goes in
- Leave the new mastic unpainted
- Ask the planning authority about consent for listed or conservation-area homes
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Cracked or broken glass
- Decayed frames that need repair
- Sash cords, weights and draught-proofing of the sashes
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
Joints and surfaces we work on

Windows and doors in Mossend
With historic houses such as Howden House (about 3.3 miles north-east) nearby, there’s older building stock in the area around Mossend as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Historic houses such as Howden House, about 3.3 miles north-east, show how far back building around Mossend goes. Rented homes near West Calder station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Advice
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What affects the quote in Mossend
Jobs vary more than people expect. What affects the quote:
- Working hours on commercial sites
- Access and height
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
Some things make a job bigger or smaller: 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.
