Window mastic in Loyter's Green, done properly
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. To get one, phone 0345 464 0079 or drop us an email with the number of frames and any access details. If you have water coming in at the bottom corners of a door and leaking joints at the ends of sills, we can help, on aluminium frames, window sills and timber windows & doors alike.
In a village or hamlet like Loyter's Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

What we are called out for in Loyter's Green
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
It’s worth asking for a quote if you see:
- Draughts coming in around windows and doors
- Old mastic that has gone black or come away
- Water coming in at the bottom corners of a door
- Hard, cracked sealant around windows
For an older house near a landmark such as Parish Church of St Mary Magdalen, the joint between an old wall and a newer frame is normally the first place rain gets in.
Before you book anyone

What the job involves on each surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Soft or decayed wood in the frame
- Condensation trapped between the panes
- Damp coming through the wall itself rather than the frame joint
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Joints and surfaces we work on

Loyter's Green homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Harlow Mill station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Wipe condensation off the frames
- Keep drainage slots and sill grooves clear
- Don’t use solvent cleaners on the joint
- Keep paint and stain on wooden frames in good order
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes most of a day for a typical house, less for a few frames and we leave things clean and tidy. Somewhere as small as Loyter's Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
