How we handle window mastic in Wateringbury
Around Wateringbury we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have cracked sealant at the sill ends and draughts coming in around windows and doors, we can put it right, on patio & French doors, window sills and composite doors alike.
In a village or hamlet like Wateringbury, older cottages and farmhouses often have timber windows set in stone or brick. 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 12-month guarantee.

How it works
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work starts. The work usually takes a morning for a couple of windows and a door. In a small place like Wateringbury, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Before we arrive
- Keep children and pets away from the work area
- Let us know about parking restrictions
- Tell us about any water getting in

For landlords and businesses
We also work for property managers and facilities teams in Wateringbury and across Kent. Several sites can be quoted together, and we’re fully insured.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Should I try it myself first?
If you are 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.
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.
Aftercare tips
To keep the joints looking good and working properly:
- Paint up to the joint, not over it
- Clear any debris from frame drain holes
- Avoid harsh chemicals near the mastic
- Avoid blasting the frames with a pressure washer
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Common problems we fix in Wateringbury
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
It’s worth asking for a quote if you see:
- Hard, cracked sealant around windows
- Mastic that’s falling out in pieces
- Leaking joints at the ends of sills
- Untidy mastic left by window fitters
For landlords with property near Wateringbury station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How the job changes by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
What window mastic looks like in Wateringbury
Historic houses like Old Soar Manor (about 4.4 miles west) are a reminder that the area around Wateringbury 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St John the Baptist include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Wateringbury Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
