Window mastic in Hextable, done properly
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. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on aluminium frames, patio & French doors and composite doors, and people most often call us about water coming in at the bottom corners of a door and a bead that doesn’t match the frame.
Houses in smaller places like Hextable can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Different surfaces, different methods
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We’ll point out any rot we find, as a joiner will need to deal with it.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Broken hinges, locks or handles
- Rotten timber, which needs a joiner first
- A failed sealed unit that has misted up
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.

Aftercare tips
After the cure time, these simple habits help:
- Walk round the house once a year and look at the joints
- Avoid blasting the frames with a pressure washer
- Keep paint off silicone joints
- Wash the frames with mild soapy water
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.

Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

I rent my home. Can I book you?
Of course. Ask your landlord first, and we can send them the quote if that helps.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, 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.
Window mastic in Hextable: local notes
With historic houses such as Hall Place and Gardens (about 2.7 miles north) nearby, there’s older building stock in the area around Hextable as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St Peter include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Hextable Primary School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Swanley station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How it works
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. A visit to Hextable is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
