How we handle window mastic in Droxford
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We work on aluminium frames, composite doors and uPVC windows, and people most often call us about old mastic that has gone black or come away and cold air getting in at the frame edge.
Outdoor sealant needs dry, clean surfaces, so work on frames around Droxford is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How it works
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours for a few frames, or a day or more for a whole house in most cases. Somewhere as small as Droxford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in

Advice
What sealant work can’t fix
We will always be straight with you, so here’s what new sealant will not do:
- Worn gaskets, brush seals or a door that has dropped
- Broken hinges, locks or handles
- Condensation trapped between the panes
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Surfaces we seal
- Aluminium frames
- Composite doors
- Timber windows & doors
- Window sills
- Patio & French doors
- uPVC windows
What the job involves on each surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
Composite doors
A composite door generally sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.
Questions from Droxford
Is Droxford in your area for window mastic?
Yes. We work across London and the South East, and Droxford is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Is there a guarantee on window mastic in Droxford?
All our work, in Droxford and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Is the new sealant paintable?
Silicone generally won’t take paint. Let us know beforehand, and we will use a paintable product where it suits.
Do you work on first-floor windows?
Yes, where they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How long before the joint can be used?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
Signs you need window mastic in Droxford
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, so it comes away long before its time.
People normally contact us when they notice one of these:
- Water coming in at the bottom corners of a door
- Draughts coming in around windows and doors
- Cracked sealant at the sill ends
- Rushed sealant from a window installation
Schools such as Droxford Junior School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- Is the old sealant removed completely?
- Is VAT in the price?
- Who turns up on the day
- Whether you can choose the colour
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep timber frames painted
- Do not aim a pressure washer at the joints
- Clear any debris from frame drain holes
- Wash the frames with mild soapy water
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.

Window mastic in Droxford: local notes
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.
For an older house near a landmark such as Church of St Mary and All Saints, the joint between an old wall and a newer frame is usually the first place rain gets in.
