Window mastic in Eaglesfield, done properly
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you have white mastic on grey or black frames and rushed sealant from a window installation, we can help, whatever the surface.
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.
Every job comes with our one-year guarantee.

Windows and doors in Eaglesfield
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
In and around Eaglesfield, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
How it works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes most of a day for a typical house, less for a few frames for a typical job. Around Eaglesfield, distance and access matter more than parking. Let us know how to find you and how to reach the joints, 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.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
- Mention any tricky access

How we quote for window mastic
Your quote is based on your job. We take into account:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- The amount of work
- How many areas need sealing
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
Photos by email are helpful but not essential. Please mention:
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, drop us a line at info@mrmastic.co.uk.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

What else we do in Eaglesfield
What we are called out for in Eaglesfield
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Keep an eye out for these signs:
- Mastic that’s falling out in pieces
- Cold air getting in at the frame edge
- Cracked or shrunken mastic around the frame
- Leaking joints at the ends of sills
Whether the job is in Eaglesfield itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before booking
- How the joint is cleaned and prepared
- What guarantee comes with the work
- Whether you can choose the colour
- Is the old sealant removed completely?
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Wipe condensation off the frames
- Keep solvents and bleach off the sealant
- Look round the frames every year or so
- Keep timber frames painted
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Signs to watch for: 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.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Worn gaskets, brush seals or a door that has dropped
- Rotten timber, which needs a joiner first
- A sash or casement that will not close properly
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
