About our window mastic in West Thurrock
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on timber windows & doors, patio & French doors and aluminium frames, and the jobs we see most are mastic that has split away from the wall and gaps where the sill meets the wall.
Many houses in smaller places like West Thurrock have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

Why act early in West Thurrock
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Around West Thurrock, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before work begins.

Signs you need window mastic in West Thurrock
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
Signs it’s time to call us include:
- Rushed sealant from a window installation
- Draughts coming in around windows and doors
- Cracked or shrunken mastic around the frame
- Old mastic that has gone black or come away

Window mastic in West Thurrock: local notes
With historic houses such as Rainham Hall (about 4.7 miles north-west) nearby, there’s older building stock in the area around West Thurrock 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Clement's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as West Thurrock Academy, larger buildings have plenty of frames, and the mastic around each one ages.

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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How the job changes by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that is a job for a joiner.
