Burham Window Mastic
Window mastic across Burham and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Cracked sealant at the sill ends

The process
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes most of a day for a typical house, less for a few frames. In a small place like Burham, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work

About our window mastic in Burham
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on aluminium frames, window sills and uPVC windows, and the jobs we see most are rain getting in at the frame or under the sill and gaps between the frame and the inside reveal.
Somewhere as small as Burham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Windows and doors in Burham
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Starkey Castle (about 2.4 miles north) nearby, there’s older building stock in the area around Burham as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near St Mary's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Snodland station, renewing tired window mastic between tenants heads off draught and damp complaints.

What happens if it’s left?
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. Around Burham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- A failed sealed unit that has misted up
- Broken hinges, locks or handles
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before booking.
Surfaces we seal
- Timber windows & doors
- Composite doors
- Window sills
- Patio & French doors
- uPVC windows
- Aluminium frames
Aftercare tips
After the cure time, these simple habits help:
- Keep paint and stain on wooden frames in good order
- Avoid harsh chemicals near the mastic
- Don’t paint over the silicone
- Air rooms to keep condensation down around windows
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

How the job changes by surface
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
What we are called out for in Burham
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
It’s worth asking for a quote if you see:
- Cracked internal joints between frame and plaster
- Gaps left after new windows were fitted
- Hard, cracked sealant around windows
- Black, perished sealant on frames
If you look after a building such as Burham Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
