Windows and doors in Enfield Island Village
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Forty Hall (about 2.3 miles west) are a reminder that the area around Enfield Island Village has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Enfield Lock station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near Ss Peter and Paul Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How we handle sand mastic in Enfield Island Village
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We are often asked to deal with cement or filler used on old window joints that has cracked and wind and rain getting in round a sash window, on stone surrounds, sash and case windows and brick reveals.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking, and access in Enfield Island Village is something to talk through when you book.
There’s a 12-month guarantee on every job.

How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours for a single window, longer for several, depending on the amount of work. In Enfield Island Village, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed

Advice
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
How we quote for sand mastic
You will get a clear quote before we start. It takes into account:
- The type of sealant required
- Working hours on commercial sites
- How much there is to do
- How many areas need sealing
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- Photos by email, if that is easy
- Any previous sealing or DIY work
Every job is quoted individually, so the first step is telling us about yours. Just phone 0345 464 0079 or send us an email with the details.

I let a flat near Enfield Lock station. Can you help?

Where are you based?

When will the new mastic be hard?

What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.
Can you match the sealant colour?
Most of the time, yes. We will explain which colours are available.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Honest limits
We will not take on work that will not last, so here’s what sealant cannot put right:
- Sashes that need overhauling
- Planning or listed building consent (your local planning authority decides)
- Decayed frames that need repair
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.
Where we work in Enfield Island Village
- Stone surrounds
- Brick reveals
- Period & listed homes
- Tenement windows
- Sash and case windows
- Timber door frames
Looking after it afterwards
To keep the joints looking good and working properly:
- Go gently near the mastic when preparing windows
- Find out about consent before window work on a listed home
- Do not paint over the new mastic
- Do not run silicone over sand mastic
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
What we are called out for in Enfield Island Village
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
Any of these means the joints need attention:
- Draughty sash windows at the surround
- Weathered mastic on the most exposed windows
- Mastic dropping out of the joint
- Patchy fillers round a sash window
If you look after a building such as Prince of Wales Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Whether the sealant suits the joint
- The length of the guarantee
- What happens if they find a problem under the old sealant
- What preparation is included
