Window mastic in Micklefield Green
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Common call-outs are for old mastic that has gone black or come away and draughts coming in around windows and doors, on patio & French doors, uPVC windows and composite doors.
Mastic can only go onto a dry, clean joint, so window work in Micklefield Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Big or small, it’s backed by our one-year guarantee.

Leave it or put it right?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. In a small place like Micklefield Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Why book with us
- Domestic, commercial and hotel work
- A sealant colour to suit the surroundings
- White, clear, grey or another colour, product permitting
- Tidy, careful work

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Do you need window mastic in Micklefield 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.
People normally contact us when they notice something like this:
- Cold air getting in at the frame edge
- Water coming in at the bottom corners of a door
- Sealant in the wrong colour for the frame
- Cracked sealant at the sill ends
For an older house near a landmark such as Church of the Holy Cross, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- How hidden problems are handled
- When the joint can take water or movement
- Whether VAT is included
- Whether you can choose the colour
Surface by surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.

Micklefield Green homes and the weather
With historic houses such as Chenies Manor House (about 2 miles west) nearby, there’s older building stock in the area around Micklefield Green as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Chorleywood station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
