Window mastic in Moorstock
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on composite doors, aluminium frames and timber windows & doors, and people most often call us about damp patches on the reveal after heavy rain and white mastic on grey or black frames.
Homes in small places like Moorstock often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes as standard.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we’re called out for in Moorstock
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Common reasons people contact us include:
- Cracked internal joints between frame and plaster
- Cold air getting in at the frame edge
- Black, perished sealant on frames
- Gaps where the sill meets the wall
If you let a flat or house near Westenhanger station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It generally takes a morning for a couple of windows and a door. For a village or hamlet like Moorstock, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises

Surface by surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Repaint timber before it’s bare
- Keep paint off silicone joints
- Keep jet washers away from the mastic
- Walk round the house once a year and look at the joints
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or email us.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- A failed sealed unit that has misted up
- A frame that has rotted at the joint
- Damp problems in the wall away from the window
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

What else we do in Moorstock
Windows and doors in Moorstock
Historic houses like Westenhanger Castle (about 1.6 miles south-east) are a reminder that the area around Moorstock has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as Sellindge Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
