About our sand mastic in Canewdon
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead, and we will talk through which suits your home. If you’re dealing with draughts and rain around sash boxes and a silicone bead on a sash window that spoils the look, we can help, whatever the surface.
In a village or hamlet like Canewdon, 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 are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

Why deal with it now?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In a small place like Canewdon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Do you need sand mastic in Canewdon?
Sand mastic slowly weathers. It hardens, cracks and starts to come away on the stone or timber.
Any of these means the joints need attention:
- Wind and rain getting in round a sash window
- Tired mastic found when preparing windows for paint
- Silicone on a period window that looks wrong
- Mastic dropping out of the joint
For site and facilities teams at buildings such as King Edmund School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- Are they insured?
- Whether the sealant suits the joint
- Who does the work, and how experienced they are
- Is VAT in the price?
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Windows and doors in Canewdon
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Althorne station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Common questions in Canewdon
Is Canewdon in your area for sand mastic?
Yes. Our work covers London and the South East, and Canewdon is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Is Canewdon within the area you cover?
Yes. Canewdon is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we’ll advise.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do you work for letting agents?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels in Canewdon.
What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How do I get a quote for sand mastic in Canewdon?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
How the visit works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours for a single window, longer for several in most cases. Somewhere as small as Canewdon, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Plan mastic work ahead of painting
- Have rotten timber repaired before new mastic goes in
- Make sure water runs off the sill
- Inspect the joints round the windows every year or so
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
