Leave it or put it right?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In a flat in Enfield Highway, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
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.

What the job involves on each surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to a full day, depending on how many windows. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Clear items away from the joints we are working on
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Enfield Highway homes and the weather
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. With historic houses such as Forty Hall (about 1.3 miles north-west) nearby, there’s older building stock in the area around Enfield Highway as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around St James' Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. As a London address, Enfield Highway can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Brimsdown station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Is parking an issue for sand mastic in Enfield Highway?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
How much does sand mastic cost in Enfield Highway?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Are you insured?
Yes. Mr Mastic is fully insured.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They decide whether consent is needed.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We also work for property managers and facilities teams in Enfield Highway and across Greater London. Several sites can be quoted together, and we are fully insured.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Go gently near the mastic when preparing windows
- Plan mastic work ahead of painting
- Look over the window mastic once a year
- Ask us before painting near the mastic
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
What affects the quote in Enfield Highway
There’s no set price list. The quote depends on:
- How many areas need sealing

- When we can work, for business premises
- How much there is to do
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
