Window mastic in Halfway Street: local notes
With historic houses such as Goodnestone Park (about 4.3 miles north) nearby, there’s older building stock in the area around Halfway Street as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Shepherds Well station, renewing tired window mastic between tenants heads off draught and damp complaints.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What we can’t put right
To be straight with you, there are a few things sealant will not fix:
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Don’t use solvent cleaners on the joint
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
- Keep timber frames painted
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
What we do, step by step
All our tools and materials come with us in the van. 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. In a small place like Halfway Street, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

Common problems we fix in Halfway Street
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
People usually contact us when they notice one of these:
- Draughty joints inside around the window
- Gaps left after new windows were fitted
- Leaking joints at the ends of sills
- White mastic on grey or black frames
For an older house near a landmark such as Church of St Andrew, the joint between an old wall and a newer frame is usually the first place rain gets in.
What to look for in a quote
- When the joint can take water or movement
- Whether they’re fully insured
- Is VAT in the price?
- The length of the guarantee
How the job changes by surface
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
