How we handle window mastic in Greenfield
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. We’re often asked to deal with white mastic on grey or black frames and old mastic that has gone black or come away, across uPVC windows, aluminium frames and composite doors.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. Access is the first thing to plan for a job in Greenfield, and in a tenement the outside of the building may be a shared repair.
Our work is backed for twelve months, in Greenfield and everywhere else we cover.

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.
A careful DIYer can reseal a simple joint, 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.
Why deal with it now?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In a tenement flat in Greenfield, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes most of a day for a typical house, less for a few frames and we leave things clean and tidy. In a city area like Greenfield, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before

Do you work for landlords with property near Shettleston station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Who arranges sealant work on the shared parts of a tenement in Greenfield?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not, and we can quote for the factor or the owners directly.

Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.

Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.
How do I get a quote for window mastic in Greenfield?
Size, access and the old material all affect the cost. Ask us for a quote.
Are you fully insured?
Yes. Full insurance covers our work.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

Keeping the joints in good condition
Aftercare is simple:
- Keep paint off silicone joints
- Keep paint and stain on wooden frames in good order
- Wash the frames with mild soapy water
- Walk round the house once a year and look at the joints
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Quotes for window mastic in Greenfield
We quote each job individually. These are the things that affect it:
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
Asking for a quote
When you contact us, these details help:
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- Any access issues, like height or stairs

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
When to call us in Greenfield
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.
The most common problems we see are:
- Hard, cracked sealant around windows
- Rushed sealant from a window installation
- Black, perished sealant on frames
- Gaps between the frame and the inside reveal
For site and facilities teams at buildings such as Eastbank Academy, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book

Windows and doors in Greenfield
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, often through a property factor. Windows generally belong to the flat, but the title deeds have the final say.
