Window mastic for homes and businesses in Sandford
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. If you’re dealing with a bead that doesn’t match the frame and hard, cracked sealant around windows, we can help.
In a village or hamlet like Sandford, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

What affects the cost of window mastic
Call for a quick quote. What matters most is:
- When we can work, for business premises
- How easy the joints are to reach
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
To help us quote quickly, please include:
- The address or postcode of the job
- Roughly how big the job is
- Any access issues, like height or stairs
- Any previous sealing or DIY work
We quote each job on its own. Just ring 0345 464 0079 or send us an email with the details and send photos if you have them.
Should I try it myself 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.
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.
Sandford homes and the weather
Sandford 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. 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.
For landlords with property near Shanklin station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Godshill Primary School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around All Saints' Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Sandford is about 5 miles south-east of Newport, in the Isle of Wight. Sandford gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. We cover 125 towns and villages across the Isle of Wight, from the larger towns to small villages. We also work in Portsmouth, about 14 miles from Sandford.
All of PO38 is covered for window mastic, from the main roads to the quietest streets. If you need window mastic at a property on Shanklin Road and Redhill Lane or a nearby road, our applicators can take on the job. Close by, we work in Whiteley Bank (1 mile east), Godshill (1 mile west), Princelett (1 mile north-east), Wroxall (1 mile south-east) and Hale Common (1 mile north). Further out, we also cover Newport (5 miles north-west), Ryde (7 miles north-east), Cowes (9 miles north), Sandown (4 miles north-east), Shanklin (3 miles east) and Ventnor (3 miles south-east). Remote and island addresses need a little more planning, so please mention your location when you call 0345 464 0079 or email us.
Around Sandford
In Sandford, that means homes and buildings near The Griffin Public House. For rail, the closest station is Shanklin station, roughly 2.5 miles east of the centre. A little further out are Sandown Castle (4.3 miles east) and Museum of Country And Agriculture (2.4 miles north). Green spaces nearby include Stenbury Down and Alverstone Mead.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep solvents and bleach off the sealant
- Keep timber frames painted
- Air rooms to keep condensation down around windows
- Look round the frames every year or so
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
What happens on the day
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. Most jobs then take a few hours for a few frames, or a day or more for a whole house. Somewhere as small as Sandford, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property

Advice
Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Older cottages and farmhouses around Sandford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and send you a clear quote before we start.

Sandford: your questions answered
Is Sandford within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Shanklin station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Can you reach windows above the ground floor?
Yes, if safe access is possible. For high or awkward windows, we’ll tell you what access is needed.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
