Three Leg Cross Window Mastic
Our applicators work in Three Leg Cross on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly.
- Water coming in at the bottom corners of a door
- White mastic on grey or black frames
- Cracked or shrunken mastic around the frame
Window mastic for homes and businesses in Three Leg Cross
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we will tell you. If you have mastic that has split away from the wall and white mastic on grey or black frames, we can help.
Somewhere as small as Three Leg Cross, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Three Leg Cross, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right 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
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
- Keep children and pets away from the work area

Windows and doors in Three Leg Cross
With historic houses such as Scotney Castle (about 2.6 miles north) nearby, there’s older building stock in the area around Three Leg Cross as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Homes close to St Mary's Church 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 Ticehurst and Flimwell Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

When it isn’t the sealant

Common problems we fix in Three Leg Cross
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.
People generally contact us after spotting something like this:
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
- Sealant in the wrong colour for the frame
- Old mastic that has gone black or come away
Rented homes near Stonegate station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Why deal with it now?
Resealing frames is a short job: it takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. Where a wall is exposed, as many are in small places like Three Leg Cross, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
What you get with us
- Old sealant always removed completely
- Colour agreed with you before work begins
- 20+ years of sealant experience
- Quality sealants from Arbo and Everbuild

Landlord and commercial work in Three Leg Cross
If you manage several properties in or around Three Leg Cross, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Different surfaces, different methods
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we’ll tell you before going ahead, as a joiner will need to deal with it.
