About our window mastic in Mossend
Around Mossend we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have whistling draughts around closed windows and gaps between the frame and the inside reveal, we can put it right.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Whatever the size of the job, it’s backed by our 12-month guarantee in Mossend and across West Lothian.

Why deal with it now?
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. Around Mossend, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.

Signs you need window mastic in Mossend
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
If you can see any of these, it’s time to have the joints looked at:
- Hard, cracked sealant around windows
- Cold air getting in at the frame edge
- A bead that doesn’t match the frame
- Draughty joints inside around the window
Rented homes near West Calder station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before you book
- Whether the sealant suits the joint
- Is VAT in the price?
- The length of the guarantee
- When the joint can take water or movement

FAQs for Mossend
Is Mossend within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you cover Mossend for window mastic?
Yes. We work across all of Scotland, and Mossend is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Can you do upstairs windows?
Generally, yes. Access is planned before we start.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Where are you based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Do you have sealant for grey or black windows?
Generally, yes. Mention the frame colour when you ask for a quote and we’ll match it as closely as we can.

Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What happens on the day
On the day, we look over the joints with you first. We protect the surfaces around the joints before work begins. The work normally takes a morning for a couple of windows and a door. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

What window mastic looks like in Mossend

Historic houses like Howden House (about 3.3 miles north-east) are a reminder that the area around Mossend has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
