Landlord and commercial work in Auldhouse
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
For anyone letting property in or around Auldhouse, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
How it works
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work starts. Most jobs take a morning for a couple of windows and a door. Outside jobs in Auldhouse need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- On commercial sites, let us know about site rules
- Tell us about any water getting in
- Clear the area around the work

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
- Do not paint over the silicone
- Avoid blasting the frames with a pressure washer
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
Surface by surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
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.
Window mastic in Auldhouse: local notes
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
If you look after a building such as Duncanrig Secondary School, the mastic around its windows and doors needs looking after like any other building’s.

Why it’s worth doing now in Auldhouse
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Around Auldhouse, 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.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

When to call us in Auldhouse
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Signs it’s time to call us include:
- Damp patches on the reveal after heavy rain
- Old mastic that has gone black or come away
- A bead that does not match the frame
- Rushed sealant from a window installation
If you let a flat or house near East Kilbride station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

FAQs for Auldhouse
I let a flat near East Kilbride station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Do you cover Auldhouse for window mastic?
Yes, Auldhouse is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we’ll send you a clear quote.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you match the sealant to my frames?
Yes, in most cases. Tell us the frame colour when you get in touch and we will use the nearest match.
What does window mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you guarantee window mastic?
Yes, with our 12-month guarantee. Keeping drainage clear and checking the joints yearly helps them last.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
