- Gaps left after new windows were fitted
How we handle window mastic in Stormontfield
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you have sealant in the wrong colour for the frame and black, perished sealant on frames, we can help.
Mastic can only go onto a dry joint, so outside work in Stormontfield depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Each job carries a 12-month guarantee.

Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
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.

What we do, step by step
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a few frames, or a day or more for a whole house. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Air rooms to keep condensation down around windows
- Avoid blasting the frames with a pressure washer
- Keep timber frames painted
- Avoid harsh chemicals near the mastic
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
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. If you notice one, it’s time to get the joint looked at.
Surface by surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Common problems we fix in Stormontfield
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
Common reasons people contact us are:
- Gaps between the frame and the inside reveal
- Black, perished sealant on frames
- Cracked sealant at the sill ends
- Cold air getting in at the frame edge
For site and facilities teams at buildings such as Bertha Park High School, larger buildings have plenty of frames, and the mastic around each one ages.

Your questions about window mastic in Stormontfield
Do you work for landlords with property near Perth station?

How much does window mastic cost in Stormontfield?
Every job is different, so each one gets its own quote. For a quick quote, send an email to info@mrmastic.co.uk with a short description of the job.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
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 place like Stormontfield, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why us?
- We are fully insured
- A sealant colour to suit the surroundings

Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
