Why act early in Ardingly
The work is quick compared with the damage it prevents: the visit takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Around Ardingly, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.
Why us?
- Neat joints and a tidy finish
- An ARBOMaster approved applicator
- One-year guarantee on every job
- White, clear, grey or coloured to suit, where the product allows

Do you need window mastic in Ardingly?
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
It’s worth asking for a quote if you see:
- Cracked sealant at the sill ends
- Rushed sealant from a window installation
- A bead that doesn’t match the frame
- Draughty joints inside around the window
If you live in an older home near St Peter's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.
What your quote should include
- Who does the work, and how experienced they are
- Whether the sealant suits the joint
- What the cure time is
- Whether they’re fully insured

What the job involves on each surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall.
Frames and glazing around Ardingly
With historic houses such as Priest House (about 2.2 miles north-east) nearby, there’s older building stock in the area around Ardingly as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like St Peter's CofE Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Balcombe station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Do not aim a pressure washer at the joints
- Wipe condensation off the frames
- Keep timber frames painted
- Don’t paint over the silicone
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
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.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
