About our window mastic in Dillarburn
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you are dealing with mastic that has split away from the wall and rain getting in at the frame or under the sill, we can help, whatever the surface.
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.
Our work is backed for twelve months.

We will not take on work that won’t last, so here’s what sealant can’t put right:
- A door that needs adjusting, rehanging or new seals
- Penetrating damp from a failed cavity tray or render

Why deal with it now?
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Around Dillarburn, 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.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
The process
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a few hours for a handful of frames, longer for a whole house in most cases. Outdoor work around Dillarburn depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property

Dillarburn homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For landlords with property near Lanark station, renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Abbeygreen Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Lesmahagow High School, its window and door frames need their mastic kept sound, just like a home’s.

Around Dillarburn

Different surfaces, different methods
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
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.
Dillarburn questions
I let a flat near Lanark station. Can you help?
Yes, we work for letting agents and landlords. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Do you cover smaller places like Dillarburn?
Yes, we do. 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.
Does the work come with a guarantee?
Yes, with our 12-month guarantee. A yearly look at the joints helps them last.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
How do I get a quote for window mastic in Dillarburn?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What affects the quote in Dillarburn
Jobs vary more than people expect. The main factors:
- Access and height
- The type of sealant required
- Any mould that needs treating
- How many areas need sealing
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
Photos by email are helpful but not essential. Please mention:
- The rough size of the job
- Whether it has been sealed before
- What’s wrong with the joints now
