Your questions about sand mastic in Loxwood
Is Loxwood within the area you cover?
Yes. Loxwood is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee on sand mastic in Loxwood?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Will there be a smell?
There can be a smell while the sealant cures. Opening a window helps.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.
Do you work for letting agents?
Yes, regularly. Several properties can be quoted together.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
How much does sand mastic cost in Loxwood?
Size, access and the old material all affect the cost. Call for a quick quote.
Sand mastic for homes and businesses in Loxwood
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. If you have weathered mastic on the most exposed windows and old cement repairs round a window that have failed, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Loxwood is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, you get the same 12-month guarantee in Loxwood and across West Sussex.

What affects the quote in Loxwood
The price is agreed before any work begins. It takes into account:
- The number and length of the joints
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- The type of sealant required
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Any previous sealing or DIY work
- Where the property is
- The rough size of the job
- Photos by email, if that’s easy
There’s no standard price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or email us.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
- Ask a joiner to look at soft timber first
- Plan mastic work ahead of painting
Do not touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Why act early in Loxwood
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In a small place like Loxwood, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Do you need sand mastic in Loxwood?
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber, and they normally need raking out.
Keep an eye out for these signs:
- Silicone on a period window that looks wrong
- Cracked mastic round a front door frame
- Wind and rain getting in round a sash window
- Weathered mastic on the most exposed windows
If you look after a building such as Loxwood Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Frames and glazing around Loxwood
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around St John the Baptist, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
