Window & door mastic in Middleton, Perth and Kinross
Window and door frames in Middleton need attention? We cut out the old, prepare the joints and apply the right sealant.
- A bead that doesn’t match the frame
- Water coming in at the bottom corners of a door
- Cracked or shrunken mastic around the frame
About our window mastic in Middleton
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We are often asked to deal with leaking joints at the ends of sills and sealant in the wrong colour for the frame, on uPVC windows, window sills and aluminium frames.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep jet washers away from the mastic
- Repaint timber before it’s bare
- Paint up to the joint, not over it
- Clean frames with a soft cloth and soapy water
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
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.
How we quote for window mastic
Your quote is based on your job. We take into account:
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- The product the joint needs
- The old material and how stubborn it is
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before any work starts.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- A few photos by email, if you can
- If someone has resealed it before

Why act early in Middleton
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In a place like Middleton, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
What you get with us
- We leave the area clean and tidy
- Old sealant always removed completely
- We agree the colour with you first
- Sanitary silicone with an anti-fungal additive in wet areas

What we’re called out for in Middleton
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.
People usually contact us when they notice one of these:
- Cracked sealant at the sill ends
- Gaps between the frame and the inside reveal
- Sealant in the wrong colour for the frame
- Hard, cracked sealant around windows
For landlords with property near Dunkeld & Birnam station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Middleton questions
Is Middleton within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Dunkeld & Birnam station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Will resealing my frames help with draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Can new window sealant be painted?
It depends on the sealant. Silicone isn’t paintable, but some hybrid sealants are. Tell us if you’re decorating and we’ll choose accordingly.
How long before the joint can be used?
It depends on the product. We tell you how long to leave it before we go.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.

How the job changes by surface
Composite doors
Front doors take the weather head on. We pay most attention there.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.
The process
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes anything from an hour or two to a full day, depending on how many frames there are. Outdoor work around Middleton depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- 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.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property

Advice
Windows and doors in Middleton
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as Old Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
