How to look after the new joints
Good habits help new joints last longer. A few tips:
- Avoid blasting the frames with a pressure washer
- Wipe condensation off the frames
- Avoid harsh chemicals near the mastic
- Don’t paint over the silicone
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
Window mastic for homes and businesses in West Mains
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a 12-month guarantee on the work. We work on timber windows & doors, uPVC windows and composite doors, and the jobs we see most are gaps where the sill meets the wall and mastic that has split away from the wall.
Outdoor sealant needs a dry surface, so window work around West Mains is planned around the weather. Let us know about access to every frame, including any upstairs.

When to call us in West Mains
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.
Common reasons people contact us are:
- Cold air getting in at the frame edge
- Sealant in the wrong colour for the frame
- Black, perished sealant on frames
- Untidy mastic left by window fitters
If you let a flat or house near East Kilbride station, renewing tired window mastic between tenants heads off draught and damp complaints.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Different surfaces, different methods
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
Common questions in West Mains
Do you cover West Mains for window mastic?
Yes. We work across all of Scotland, and West Mains is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Can you help a landlord with a rental near East Kilbride station?
Yes, landlords and agents are among the people we work for. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we will choose accordingly.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you have insurance?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.

What else we do in West Mains
Windows and doors in West Mains
West Mains is in the west of Scotland, which is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Managing a site like St Andrew's and St Bride's High School? Then its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near West Kirk, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours for a handful of frames, longer for a whole house. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
