Why act early in Mid Holmwood
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Mid Holmwood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

How we handle window mastic in Mid Holmwood
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on uPVC windows, patio & French doors and composite doors, and common reasons people get in touch are sealant in the wrong colour for the frame and cracked sealant at the sill ends.
Around Mid Holmwood, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, it’s backed by our one-year guarantee in Mid Holmwood and across Surrey.

Signs you need window mastic in Mid Holmwood
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
The most common problems we see are:
- Cracked or shrunken mastic around the frame
- Cracked internal joints between frame and plaster
- Untidy mastic left by window fitters
- Mastic that is falling out in pieces

Different surfaces, different methods
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

What else we do in Mid Holmwood
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep timber frames painted
- Do not use solvent cleaners on the joint
- Make sure the drainage slots are not blocked
- Keep jet washers away from the mastic
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
Windows and doors in Mid Holmwood
Historic houses like Polesden Lacey (about 4.2 miles north-west) are a reminder that the area around Mid Holmwood has older buildings as well as new. Where a home is older, 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.
Homes close to Church of St John the Evangelist include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as St John's Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
