Frames and glazing around Childerditch
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hare Hall (about 4.8 miles west) are a reminder that the area around Childerditch has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you look after a building such as Woodlands School Great Warley, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as All Saints and St Faith, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Childerditch, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Tell us if parking is tricky
- Keep children and pets away from the work area
- Move anything stored near the joints

Surface by surface
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall.
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.
Childerditch: your questions answered
Can you help a landlord with a rental near West Horndon station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Will you come out to Childerditch?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Can you match the sealant to my frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
Aftercare tips
A little care helps the new joints last. Our advice:
- Walk round the house once a year and look at the joints
- Paint up to the joint, not over it
- Wash the frames with mild soapy water
- Keep drainage slots and sill grooves clear
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
When to call us in Childerditch
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
The problems people normally mention when they call include:
- A bead that does not match the frame
- Mastic that has split away from the wall
- Gaps where the sill meets the wall
- Whistling draughts around closed windows
Rented homes near West Horndon station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- When the joint can take water or movement
- What insurance they hold
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
When something else is needed
To be straight with you, there are a few things sealant will not fix:
- A door that needs adjusting, rehanging or new seals
- Damp problems in the wall away from the window
- Broken hinges, locks or handles
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

Why it’s worth doing now in Childerditch
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Older cottages and farmhouses around Childerditch can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
