Palestine Window Mastic
Mastic around window and door frames, sills and patio doors for homes and businesses in Palestine and across Hampshire. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Water coming in at the bottom corners of a door
- Mastic that’s falling out in pieces
- Mastic that has split away from the wall
Keeping the joints in good condition
Aftercare is simple:
- Make sure the drainage slots are not blocked
- Do not use solvent cleaners on the joint
- Clean frames with a soft cloth and soapy water
- Avoid blasting the frames with a pressure washer
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Window mastic in Palestine, done properly
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Typical jobs include untidy mastic left by window fitters and hard, cracked sealant around windows, across aluminium frames, timber windows & doors and window sills.
In a village or hamlet like Palestine, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Frames and glazing around Palestine
Historic houses like Idmiston Manor (about 4.7 miles south-west) are a reminder that the area around Palestine 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Grateley Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Grateley station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Palestine is in Hampshire. Anywhere in SP11, our applicators can take on window mastic. Palestine is one of 683 places in Hampshire where we work. Our Southampton page covers work nearby, about 20 miles away.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We cut it out and start again.
What we can’t put right
We will not take on work that will not last, so these are the limits:
- A sash or casement that won’t close properly
- Draughts through the window seals rather than the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
Joints and surfaces we work on
- Window sills
- Patio & French doors

Why act early in Palestine
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. In a small place like Palestine, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

What we’re called out for in Palestine
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.
Signs it’s time to call us include:
- Draughty joints inside around the window
- Whistling draughts around closed windows
- Damp patches on the reveal after heavy rain
- Gaps left after new windows were fitted
For an older house near a landmark such as Church of St Leonard, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Palestine, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- 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.

- Tell us about any water getting in
- Let us know about parking restrictions
