Window mastic in East Horndon
Around East Horndon we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Typical jobs include mastic that has split away from the wall and rain getting in at the frame or under the sill, across composite doors, window sills and timber windows & doors.
In a village or hamlet like East Horndon, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Questions from East Horndon
Do you work for landlords with property near West Horndon station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Will you come out to East Horndon?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Will resealing my frames help with draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
How many windows can you do in a day?
Allow a morning for a couple of windows and a door. Access and how stubborn the old mastic is affect the time most.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Do you have insurance?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Why deal with it now?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around East Horndon can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Advice
What the job involves on each surface
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Clear any debris from frame drain holes
- Clean frames with a soft cloth and soapy water
- Do not aim a pressure washer at the joints
- Ventilate rooms so frames do not stay wet inside
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Quotes for window mastic in East Horndon
Jobs vary more than people expect. The main factors:
- How easy the joints are to reach
- The number of rooms or windows
- When we can work, for business premises
- Which sealant suits the joint
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
Helping us quote

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work and give you a clear price.
Signs you need window mastic in East Horndon
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
The problems people normally mention when they call are:
- Leaking joints at the ends of sills
- Rushed sealant from a window installation
- Sealant in the wrong colour for the frame
- Black, perished sealant on frames
For site and facilities teams at buildings such as West Horndon Primary School, its window and door frames need their mastic kept sound, just like a home’s.
