Window mastic in Tilmanstone
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. That way the new bead bonds to the frame and the wall only. We work on aluminium frames, window sills and timber windows & doors, and the jobs we see most are water coming in at the bottom corners of a door and draughty joints inside around the window.
Outdoor sealant needs dry, clean surfaces, so work on frames around Tilmanstone is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee, whatever its size.

What the job involves on each surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Don’t use solvent cleaners on the joint
- Check the mastic once a year
- Clear any debris from frame drain holes
- Wipe condensation off the frames
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
Look out for the warning signs: 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.
How it works
The work is kept neat and contained to the area we are working on. Expect the work to take a morning for a couple of windows and a door, and we explain the cure time before we leave. Somewhere as small as Tilmanstone, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Tell us if parking is tricky

Frames and glazing around Tilmanstone
With historic houses such as Goodnestone Park (about 3.5 miles north-west) nearby, there’s older building stock in the area around Tilmanstone as well as newer homes.

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 Andrew include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Signs you need window mastic in Tilmanstone
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. Backing rod sets the right depth.
Look out for any of the following:
- Cracked internal joints between frame and plaster
- Cracked or shrunken mastic around the frame
- Rain getting in at the frame or under the sill
- Untidy mastic left by window fitters
Rented homes near Shepherds Well station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the 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.
