Window mastic in Newmilns
Around Newmilns we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have whistling draughts around closed windows and old mastic that has gone black or come away, we can put it right, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Different surfaces, different methods
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.

What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take most of a day for a typical house, less for a few frames. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- 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.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

Advice
Newmilns homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Managing a site like Loudoun Academy? Then larger buildings have plenty of frames, and the mastic around each one ages.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Common problems we fix in Newmilns
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Common reasons people contact us are:
- Black, perished sealant on frames
- Gaps between the frame and the inside reveal
- Mastic that has split away from the wall
- Gaps where the sill meets the wall
Homes close to Loudoun Old Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before you book
- How long the guarantee is
- Whether the sealant suits the joint
- How long to leave it before use
- What happens if they find a problem under the old sealant
Keeping the joints in good condition
After the cure time, these simple habits help:
- Paint up to the joint, not over it
- Clean frames with a soft cloth and soapy water
- Keep solvents and bleach off the sealant
- Check the mastic once a year
Most silicone sealants won’t take paint, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.

Why it’s worth doing now in Newmilns
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Around Newmilns, water from a failed joint in an older stone home can soak into timber and plaster.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
