About our window mastic in Snowdown
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have water coming in at the bottom corners of a door and rushed sealant from a window installation, we can put it right.
Somewhere as small as Snowdown, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
You get a 12-month guarantee, the same in Snowdown as everywhere else we work.

What happens on the day
We keep the work tidy and contained to the joints we’re treating. The job normally takes a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. In a small place like Snowdown, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.

Advice
What happens if it’s left?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Older cottages and farmhouses around Snowdown can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What we are called out for in Snowdown
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
If you can see any of these, it’s time to have the joints looked at:
- Water coming in at the bottom corners of a door
- Leaking joints at the ends of sills
- Gaps between the frame and the inside reveal
- Mastic that is falling out in pieces
If you let a flat or house near Snowdown station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Window mastic in Snowdown: local notes
With historic houses such as Goodnestone Park (about 2 miles north) nearby, there’s older building stock in the area around Snowdown as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as St Joseph's Catholic Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near St Peter, the joint between an old wall and a newer frame is usually the first place rain gets in.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Soft or decayed wood in the frame
- A door that needs adjusting, rehanging or new seals
- Penetrating damp from a failed cavity tray or render
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.
Surfaces we seal
