Common problems we fix in Ecchinswell
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Look out for any of the following:
- Gaps where the sill meets the wall
- Gaps left after new windows were fitted
- Black, perished sealant on frames
- Draughty joints inside around the window
If you let a flat or house near Thatcham station, renewing tired window mastic between tenants heads off draught and damp complaints.

How we handle window mastic in Ecchinswell
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you have rain getting in at the frame or under the sill and sealant in the wrong colour for the frame, we can put it right, whatever the surface.
In a village or hamlet like Ecchinswell, 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.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a morning for a couple of windows and a door. For a village or hamlet like Ecchinswell, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.

Why act early in Ecchinswell
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. Resealing now is a small job by comparison. Older cottages and farmhouses around Ecchinswell can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Take a look at what affects the cost or our reviews.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Your questions about window mastic in Ecchinswell
I let a flat near Thatcham station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Can you do window mastic in Ecchinswell?
Yes, Ecchinswell is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Mention any painting plans before we start.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Will new mastic stop draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Are you fully insured?
Yes. We are fully insured for every job we do.
Window mastic in Ecchinswell: local notes
Historic houses like Highclere Castle (about 3.4 miles west) are a reminder that the area around Ecchinswell has older buildings as well as new. In older buildings, 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 Lawrence, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Ecchinswell and Sydmonton Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How the job changes by surface
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall and tooled smooth.
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep drainage slots and sill grooves clear
- Don’t aim a pressure washer at the joints
- Check the mastic once a year
- Ventilate rooms so frames do not stay wet inside
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
