Do you need window mastic in Great Warley?
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Look out for these signs:
- Sealant in the wrong colour for the frame
- Rain getting in at the frame or under the sill
- Gaps between the frame and the inside reveal
- Mastic that’s falling out in pieces
For an older house near a landmark such as St. Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Window mastic for homes and businesses in Great Warley
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on patio & French doors, composite doors and window sills, and common reasons people get in touch are whistling draughts around closed windows and white mastic on grey or black frames.
Somewhere as small as Great Warley, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Big or small, you get the same one-year guarantee in Great Warley and across Essex.

Joints and surfaces we work on
- Composite doors
- Aluminium frames
- uPVC windows
- Window sills
- Timber windows & doors
- Patio & French doors
Different surfaces, different methods
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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, then guaranteed for a year.
Great Warley homes and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hare Hall (about 3.3 miles west) are a reminder that the area around Great Warley 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.
For landlords with property near Brentwood station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Schools such as Woodlands School Great Warley are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.

- We tool each bead neatly and check every joint is closed.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
