About our window mastic in Turnford
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. Typical jobs include white mastic on grey or black frames and leaking joints at the ends of sills, across aluminium frames, patio & French doors and window sills.
Homes around Turnford range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
Whatever the size of the job, it’s backed by our 12-month guarantee in Turnford and across Hertfordshire.

Why act early in Turnford
Resealing frames is a short job: the visit takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. In a smaller place like Turnford, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Turnford questions
Can you do window mastic in Turnford?
Yes, Turnford is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.
Will you come out to Turnford?
Yes. Turnford is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Can you get sealant to suit coloured frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
Aftercare tips
So the new joints stay in good condition:
- Keep solvents and bleach off the sealant
- Keep jet washers away from the mastic
- Keep drainage slots and sill grooves clear
- Use gentle cleaners on frames and sealant
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Window mastic in Turnford: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Forty Hall (about 4 miles south-west) nearby, there’s older building stock in the area around Turnford 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.
Rented homes near Cheshunt station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near St Clement, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Turnford is about 1 mile north-east of Cheshunt, in Hertfordshire. Every kind of property in Turnford can book us for window mastic. The work is guaranteed for a year. Our area takes in 381 places across Hertfordshire, large and small. We also work in London, around 16 miles away.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes most of a day for a typical house, less for a few frames from start to finish. A visit to Turnford is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

Surface by surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Common problems we fix in Turnford
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
If you can see any of these, it’s time to have the joints looked at:
- Water coming in at the bottom corners of a door
- Cracked sealant at the sill ends
- Gaps between the frame and the inside reveal
- Draughts coming in around windows and doors
For site and facilities teams at buildings such as Longlands Primary School and Nursery, its window and door frames need their mastic kept sound, just like a home’s.
