- Black, perished sealant on frames
Surface by surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Composite doors
A composite door generally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
How we handle window mastic in Ansteadbrook
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. Typical jobs include water coming in at the bottom corners of a door and gaps where the sill meets the wall, on window sills, timber windows & doors and patio & French doors.
In a village or hamlet like Ansteadbrook, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Repaint timber before it’s bare
- Check the mastic once a year
- Avoid blasting the frames with a pressure washer
- Paint up to the joint, not over it
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or email us.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
FAQs for Ansteadbrook
Do you cover Ansteadbrook for window mastic?
Yes, Ansteadbrook is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
I let a flat near Haslemere station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Can you work on commercial sites?

Why deal with it now?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. Older cottages and farmhouses around Ansteadbrook can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

Signs you need window mastic in Ansteadbrook
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Look out for these signs:
- Sealant in the wrong colour for the frame
- Cracked sealant at the sill ends
- Mastic that’s falling out in pieces
- Cold air getting in at the frame edge
If you let a flat or house near Haslemere station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
How the visit works
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for a few frames, or a day or more for a whole house, including the tidy-up. For a village or hamlet like Ansteadbrook, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
