About our window mastic in Sprouston
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. To get one, drop us a line at info@mrmastic.co.uk with the number of frames and any access details. If you have cracked sealant at the sill ends and black, perished sealant on frames, we can help.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Why deal with it now?
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. 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.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.

What else we do in Sprouston
Landlords, agents and businesses in Sprouston
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What we do, step by step
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. It normally takes a few hours for a handful of frames, longer for a whole house. Around Sprouston, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Mention any tricky access
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children

Windows and doors in Sprouston
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Homes close to Sprouston Parish Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

When something else is needed
A few problems are outside what sealant work can do:
- Soft or decayed wood in the frame
- Worn gaskets, brush seals or a door that has dropped
- Damp coming through the wall itself rather than the frame joint

Signs you need window mastic in Sprouston
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Any of these means the joints need attention:
- Rushed sealant from a window installation
- Damp patches on the reveal after heavy rain
- Cracked sealant at the sill ends
- A bead that does not match the frame
For site and facilities teams at buildings such as Kelso High School, its window and door frames need their mastic kept sound, just like a home’s.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, 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.
FAQs for Sprouston
Is Sprouston within the area you cover?
Yes, Sprouston is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is there a guarantee on window mastic in Sprouston?
All our work, in Sprouston and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
Will new mastic stop draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Where do you work from?
We work from Crawley. We cover Sprouston and the rest of the Scottish Borders, along with the rest of our area.
How the job changes by surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
