Window mastic for homes and businesses in Whitelees
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. Typical jobs include mastic that’s falling out in pieces and gaps between the frame and the inside reveal, across uPVC windows, composite doors and timber windows & doors.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
Your job is guaranteed for a year, as with all our work.

What we are called out for in Whitelees
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. If the sealant cannot stretch, it splits.
Any of these means the joints need attention:
- Cracked sealant at the sill ends
- A bead that doesn’t match the frame
- Gaps between the frame and the inside reveal
- Rushed sealant from a window installation
Schools such as Abronhill High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- Which colour the sealant will be
- What guarantee comes with the work
- What happens if the job turns out different
- Whether VAT is included
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What affects the quote in Whitelees
The quote reflects the job in front of us. We take into account:
- Any working-time requirements on site
- How much there is to do
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- The address or postcode of the job
- Access, such as stairs, a lift or height
- Roughly how big the job is
- Whether it’s a home or a business
Every job is quoted individually, so start by telling us what you need. Just email us at info@mrmastic.co.uk with the details.
How the visit works
Before we leave, we go over the finished joints with you. The work normally takes a morning for a couple of windows and a door, depending on the size of the job. For a place like Whitelees, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints

How do I get a quote for window mastic in Whitelees?
Every job is different, so each one gets its own quote. To get one, email us at info@mrmastic.co.uk and tell us what needs doing and where.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
When it is not the sealant
In fairness, some problems need a different trade:
- Rotten timber, which needs a joiner first
- A door that needs adjusting, rehanging or new seals
- Damp problems in the wall away from the window
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.

Whitelees homes and the weather
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you let a flat or house near Cumbernauld station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What happens if it’s left?
The work is quick compared with the damage it prevents: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. In a place like Whitelees, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Surface by surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
