Window mastic in Minnow End
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 is why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on window sills, patio & French doors and aluminium frames, and people most often call us about black, perished sealant on frames and leaking joints at the ends of sills.
Homes in small places like Minnow End often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Window mastic in Minnow End: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Beaulieu Park station, renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near Church of SS Mary and Laurence, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
What sealant work cannot fix
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first
- Damp problems in the wall away from the window
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.
What we seal
- Aluminium frames
- Window sills
- Patio & French doors
- uPVC windows
- Composite doors
- Timber windows & doors
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep paint off silicone joints
- Look round the frames every year or so
- Keep paint and stain on wooden frames in good order
- Don’t use solvent cleaners on the joint
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

Advice
Questions from Minnow End
I let a flat near Beaulieu Park station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Is Minnow End within the area you cover?
Yes. Minnow End is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Where do you work from?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you do upstairs windows?
Normally, yes. Access is planned before any work starts.
Can new window sealant be painted?
That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Tell us if you are decorating and we’ll choose accordingly.
Signs you need window mastic in Minnow End
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
The most common problems we see are:
- Damp patches on the reveal after heavy rain
- Cracked sealant at the sill ends
- Cold air getting in at the frame edge
- Black, perished sealant on frames
If you look after a building such as Chelmer Valley High School, its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- How the surfaces are prepared before sealing
- How much experience the applicator has
- Whether VAT is included
- Whether they seal over old material or remove it
