Window & door mastic in Pathhead, Midlothian
Window and door frames in Pathhead need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Cracked sealant at the sill ends
- Black, perished sealant on frames
- A bead that does not match the frame
Window mastic in Pathhead
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Common call-outs are for cracked or shrunken mastic around the frame and black, perished sealant on frames, across aluminium frames, timber windows & doors and uPVC windows.
Mastic can only go onto a dry joint, so outside work in Pathhead depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What sealant work cannot fix
We will always be straight with you, so here’s what new sealant won’t do:
- Worn gaskets, brush seals or a door that has dropped
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Broken hinges, locks or handles
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.
Joints and surfaces we work on
- Composite doors
- Timber windows & doors
- Window sills
- Aluminium frames
- uPVC windows
- Patio & French doors
Surface by surface
Composite doors
An exposed front door gets wind-driven rain. We pay most attention there.
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.
Windows and doors in Pathhead
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.
In and around Pathhead, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

What else we do in Pathhead
Signs you need window mastic in Pathhead
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.
Keep an eye out for these signs:
- Gaps between the frame and the inside reveal
- White mastic on grey or black frames
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
Letting a property close to Gorebridge station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a morning for a couple of windows and a door. Outdoor work around Pathhead depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules

Advice
Why deal with it now?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Around Pathhead, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

Common questions in Pathhead
Do you work for landlords with property near Gorebridge station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Is Pathhead within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Can you do upstairs windows?
Yes, in most cases. Access is planned before we start.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Use gentle cleaners on frames and sealant
- Keep drainage slots and sill grooves clear
- Repaint timber before it’s bare
- Don’t aim a pressure washer at the joints
Most silicone sealants will not take paint, so mention any painting plans before we start. There are paintable sealants for joints that need it.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
