Sand mastic in Chillenden
We work across Chillenden renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We’re often asked to deal with window mastic to renew ahead of painting and gaps between timber frames and stone or brick, on timber door frames, stone surrounds and period & listed homes.
Mastic can only go onto a dry, clean joint, so window work in Chillenden is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

Chillenden homes and the weather
With historic houses such as Goodnestone Park (about 1.2 miles north-west) nearby, there’s older building stock in the area around Chillenden as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Aylesham station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Near you in Chillenden
The nearest railway station is Aylesham station, roughly 1.9 miles west. Not far away are Monk's Wall nature reserve.
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
FAQs for Chillenden
Will you come out to Chillenden?
Yes, Chillenden is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Aylesham station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. Period windows in stone or brick generally suit sand mastic, while modern frames normally get a flexible sealant.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

How it works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours per window, depending on the condition of the joints for a typical job. Somewhere as small as Chillenden, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints
Ask for a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Advice
Why deal with it now?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Where a wall is exposed, as many are in small places like Chillenden, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.

Do you need sand mastic in Chillenden?
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
If you can see any of these, it’s time to have the joints looked at:
- Mastic dropping out of the joint
- Gaps round a timber door in stone or brick
- Tired mastic found when preparing windows for paint
- A silicone bead on a sash window that spoils the look
Schools such as Goodnestone Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- How the colour is chosen
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
- What the cure time is
How the job changes by surface
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
How we quote for sand mastic
For a quick quote, just ask. The main things that affect it are:
- The old material and how stubborn it is
- The number of rooms or windows
- The product the joint needs
- Any mould that needs treating
Doing several joints on one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
What we need to know
When you call or email, these details help:
- Whether it has been sealed before
