Window mastic in Steward's Green
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that cannot move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. We’re often asked to deal with mastic that has split away from the wall and whistling draughts around closed windows, across timber windows & doors, aluminium frames and composite doors.
In a village or hamlet like Steward's Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We stand behind the work with a one-year guarantee.

Why deal with it now?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. Older cottages and farmhouses around Steward's Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Frames and glazing around Steward's Green
With historic houses such as Hill Hall (about 1.6 miles south-east) nearby, there’s older building stock in the area around Steward's Green as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Ivy Chimneys Primary School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St John the Baptist include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

What the job involves on each surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.
How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Steward's Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we’re working on
- Keep children and pets away from the work area

When it is not the sealant
It helps to know what we can’t do too:
- A frame that has rotted at the joint
- Worn gaskets, brush seals or a door that has dropped
- A sash or casement that will not close properly
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

- Patio & French doors
- Window sills

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep jet washers away from the mastic
- Keep paint off silicone joints
- Look round the frames every year or so
- Clear any debris from frame drain holes
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just phone 0345 464 0079 or drop us an email.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
