Window Mastic in Maryton
We cover Maryton for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

Do you need window mastic in Maryton?
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. That is what backing rod is for.
The problems people normally mention when they call are:
- Leaking joints at the ends of sills
- White mastic on grey or black frames
- Old mastic that has gone black or come away
- Draughts coming in around windows and doors
In and around Maryton, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Window mastic for homes and businesses in Maryton
Around Maryton we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Common call-outs are for mastic that has split away from the wall and untidy mastic left by window fitters, across patio & French doors, window sills and uPVC windows.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All our work is covered by our 12-month guarantee.

For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.
What we can’t put right
To be straight with you, some problems need a different trade:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
- Faulty window hardware
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.

What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of frames, longer for a whole house. For a place like Maryton, 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.
- 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.

Window mastic in Maryton: local notes
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. 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.
Homes close to St Andrew's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Surface by surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Walk round the house once a year and look at the joints
- Keep solvents and bleach off the sealant
- Wipe condensation off the frames
- Make sure the drainage slots aren’t blocked
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.

Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames usually suit brown.
