Sand mastic in Turnpike Lane
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. Common call-outs are for old cement repairs round a window that have failed and draughty sash windows at the surround, across tenement windows, timber door frames and sash and case windows.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease normally says who is responsible for the windows, so it’s worth checking before booking, and access in Turnpike Lane is something to talk through when you book.
You get a 12-month guarantee, the same in Turnpike Lane as everywhere else we work.

Surface by surface
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. It’s renewed by hand.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we tell you how long to leave it before we go. 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.
- We look at the surrounds with you and agree the joints to renew.
- 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.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- On commercial sites, let us know about site rules

Turnpike Lane homes and the weather
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Historic houses like Bruce Castle (about 1.5 miles north-east) are a reminder that the area around Turnpike Lane has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Hornsey station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. As a London address, Turnpike Lane can be tricky for parking: let us know about parking bays, permits or a driveway. In the older streets around Church of St John The Baptist (greek Orthodox), replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What affects the cost of sand mastic
Jobs vary more than people expect. What affects the quote:
- The amount of work
- How easy the joints are to reach
- The old material and how stubborn it is
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the property is
- A few pictures by email, if you can
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking

Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
How long will you be here?
That depends on how much there is to do, but most jobs take a few hours for a single window, longer for several. We’ll give you a better idea when we quote.
What do you need from me for a quote?

Can I choose the sealant colour?
In most cases you can choose. We’ll explain which colours are available.
DIY versus a professional finish
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.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Get any rot dealt with first
- Go gently near the mastic when preparing windows
- Check with your local planning authority if your home is listed
- Ask us before painting near the mastic
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
