What we do, step by step
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. The job usually takes most of a day for a typical house, less for a few frames. In a small place like Hattingley, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

Advice
How we handle window mastic in Hattingley
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. Typical jobs include hard, cracked sealant around windows and cracked internal joints between frame and plaster, on timber windows & doors, window sills and uPVC windows.
In a village or hamlet like Hattingley, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

Window mastic in Hattingley: local notes
Historic houses like Bentworth Hall (about 1.9 miles north-east) are a reminder that the area around Hattingley has older buildings as well as new. 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. Compared with the north and west, the South East gets less rain, 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 Church of St Andrew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Signs you need window mastic in Hattingley
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
The most common problems we see are:
- Water coming in at the bottom corners of a door
- Draughty joints inside around the window
- Mastic that has split away from the wall
- Old mastic that has gone black or come away
If you look after a building such as Medstead Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- Whether the sealant suits the joint
- What happens if the job turns out different
- Whether all the old sealant comes out first
- How the surfaces are prepared before sealing
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Clean frames with a soft cloth and soapy water
- Air rooms to keep condensation down around windows
- Keep paint and stain on wooden frames in good order
- Keep jet washers away from the mastic
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Why it’s worth doing now in Hattingley
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Where a wall is exposed, as many are in small places like Hattingley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
