About our window mastic in Horam
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We work on patio & French doors, window sills and aluminium frames, and the jobs we see most are damp patches on the reveal after heavy rain and whistling draughts around closed windows.
In a village or hamlet like Horam, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All our work is covered by a one-year guarantee.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Paint up to the joint, not over it
- Keep solvents and bleach off the sealant
- Ventilate rooms so frames don’t stay wet inside
- Check the mastic once a year
Silicone cannot usually be painted, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Soft or decayed wood in the frame
- Faulty window hardware
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

Window mastic in Horam: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Horselunges Manor (about 3.2 miles south) nearby, there’s older building stock in the area around Horam 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.
For an older house near a landmark such as Christ Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What else we do in Horam
Common problems we fix in Horam
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
It’s worth asking for a quote if you see:
- Gaps where the sill meets the wall
- Cold air getting in at the frame edge
- Mastic that has split away from the wall
- A bead that does not match the frame
For site and facilities teams at buildings such as Maynards Green Community Primary School, the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- Who turns up on the day
- The length of the guarantee
- How the surfaces are prepared before sealing
- What insurance they hold
What happens on the day
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take a morning for a couple of windows and a door. Somewhere like Horam needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children

FAQs for Horam
What guarantee comes with window mastic in Horam?
All our work, in Horam and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Horam?
Yes. Horam 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 the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
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 will tell you how long your job needs when we quote.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is the new sealant paintable?
Silicone generally will not take paint. Let us know beforehand, and we’ll use a paintable product where it suits.
Are you fully insured?
Yes. We’re fully insured.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
Landlord and commercial work in Horam
We also work for property managers and facilities teams in Horam and across East Sussex. We can quote a run of properties together, and we’re fully insured.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
Leave it or put it right?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Horam can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.
