Window Mastic in Keith
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Keith. Fully insured, ARBOMaster approved and guaranteed for a year.
- Cracked or shrunken mastic around the frame
- Damp patches on the reveal after heavy rain
- Gaps left after new windows were fitted
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Window mastic for homes and businesses in Keith
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. Typical jobs include water coming in at the bottom corners of a door and gaps left after new windows were fitted, across aluminium frames, window sills and patio & French doors.
In and around a place like Keith, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
All our work comes with our one-year guarantee.

Keeping the joints in good condition
Looking after new joints is easy:
- Look round the frames every year or so
- Air rooms to keep condensation down around windows
- Keep timber frames painted
- Don’t paint over the silicone
Keep the new mastic undisturbed while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
The process
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. Outside jobs in Keith 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. Indoor work goes ahead whatever the weather.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Mention any tricky access

Advice
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Broken hinges, locks or handles
- A failed sealed unit that has misted up
- Draughts through the window seals rather than the frame

Do you work on first-floor windows?

Do you have sealant for grey or black windows?

What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply email us at info@mrmastic.co.uk.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we will tell you.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Different surfaces, different methods
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
Why deal with it now?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. In an older home around Keith, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Keith homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of 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.
Letting a property close to Keith station? Then renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as St Rufus Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Keith Grammar School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
