How we handle window mastic in Skinner's Hill
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on aluminium frames, timber windows & doors and window sills, and people most often call us about mastic that’s falling out in pieces and cold air getting in at the frame edge.
Outdoor sealant needs dry, clean surfaces, so work on frames around Skinner's Hill is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Do you need window mastic in Skinner's Hill?
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
Most people get in touch when they notice something like this:
- Old mastic that has gone black or come away
- Gaps left after new windows were fitted
- Water coming in at the bottom corners of a door
- Hard, cracked sealant around windows
If you live in an older home near All Saints' Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Skinner's Hill: your questions answered
Does living near the coast affect window mastic in Skinner's Hill?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
I let a flat near Sandown station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Do you cover Skinner's Hill?
We do. Skinner's Hill is part of the area we cover, and the service is the same as everywhere else.
Do you work on first-floor windows?
Normally, yes. Access is planned before work begins.
Where are you based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

Frames and glazing around Skinner's Hill
Skinner's Hill is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. 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.
Rented homes near Sandown station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Newchurch Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Why act early in Skinner's Hill
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Around Skinner's Hill, 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 guesswork. That is why we ask about the job first and agree the price before starting.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Look round the frames every year or so
- Clear any debris from frame drain holes
- Wipe condensation off the frames
- Use gentle cleaners on frames and sealant
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Worn gaskets, brush seals or a door that has dropped
- Rotten timber, which needs a joiner first
- A failed sealed unit that has misted up
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.

The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Skinner's Hill needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
