Window mastic for homes and businesses in Eastfield
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you are dealing with gaps left after new windows were fitted and whistling draughts around closed windows, we can put it right, whatever the surface.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

Common questions in Eastfield
I let a flat near Blackridge station. Can you help?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Is Eastfield within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will resealing my frames help with draughts?
In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Is it messy?
We keep the work tidy. We protect what’s around the joints.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
What sealant work cannot fix
To be straight with you, there are a few things sealant will not fix:
- Damp problems in the wall away from the window
- Soft or decayed wood in the frame
- Draughts through the window seals rather than the frame
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.
What we seal
- Timber windows & doors
- Patio & French doors
- Composite doors
- Window sills
- uPVC windows

What happens on the day
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Eastfield may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Preparing for the visit
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before

What window mastic looks like in Eastfield
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.

DIY versus a professional finish
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, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
When to call us in Eastfield
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
It’s worth asking for a quote if you see:
- Black, perished sealant on frames
- Rain getting in at the frame or under the sill
- Whistling draughts around closed windows
- Sealant in the wrong colour for the frame
Letting a property close to Blackridge station? Then 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
- How the colour is chosen
- What preparation is included

How we quote for window mastic

- When we can work, for business premises
- Mould in or behind the old joints
- Access and height
Instead of a standard rate, 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.
Helping us quote
You don’t need to know the technical terms. Just tell us:
- A few pictures by email, if you can
- The address or postcode of the job
- The type of property
- Access, such as stairs, a lift or height
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Avoid harsh chemicals near the mastic
- Look round the frames every year or so
- Make sure the drainage slots aren’t blocked
- Do not paint over the silicone
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
