About our window mastic in West Green
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you have gaps where the sill meets the wall and hard, cracked sealant around windows, we can help, whatever the surface.
In a smaller place like West Green, some walls face open ground and catch the full force of the weather. That’s hard on the mastic around frames and sills.
Whatever the size of the job, you get the same 12-month guarantee in West Green and across West Sussex.

Do you need window mastic in West Green?
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
The problems people generally mention when they call are:
- Gaps left after new windows were fitted
- Gaps where the sill meets the wall
- Black, perished sealant on frames
- Draughts coming in around windows and doors
Rented homes near Crawley station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before booking
- Who turns up on the day
- What product goes in the joint
- How long the guarantee is
- What preparation is included
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Damp coming through the wall itself rather than the frame joint
- Condensation trapped between the panes
- Draughts through the window seals rather than the frame
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
If you are set on DIY, put the effort into 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.
Window mastic in West Green: local notes
West Green is part of Crawley, one of the post-war new towns. Many homes date from the post-war decades, and many will have had their original windows replaced. That mastic ages as well, and sills and frame heads are where leaks start. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as West Green Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Voice of Deliverance Full Gospel Church of God, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
West Green is about 1 mile north of Crawley, in West Sussex. We carry out window mastic for homes and businesses in West Green, as part of our work across West Sussex. West Green is one of 371 places in West Sussex where we work for window mastic.

Aftercare tips
Looking after new joints is easy:
- Keep solvents and bleach off the sealant
- Keep jet washers away from the mastic
- Clear any debris from frame drain holes
- Use gentle cleaners on frames and sealant
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
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. If you notice one, it’s time to get the joint looked at.

What else we do in West Green
How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours for a handful of frames, longer for a whole house. In a smaller place like West Green, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Why it’s worth doing now in West Green
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In an older home around West Green, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Doing several joints on one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.
