Why it’s worth doing now in Four Oaks
New sash windows are a major, costly change, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. In a small place like Four Oaks, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

How we handle sand mastic in Four Oaks
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on timber door frames, sash and case windows and tenement windows, and people most often call us about weathered mastic on the most exposed windows and mastic dropping out of the joint.
Mastic can only go onto a dry, clean joint, so window work in Four Oaks is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All of our work is guaranteed for twelve months.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to a full day, depending on how many windows from start to finish. In a small place like Four Oaks, access is usually the main thing to plan. 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.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Inspect the joints round the windows every year or so
- Keep modern sealant off the mastic
- Leave the new mastic unpainted
- Find out about consent before window work on a listed home
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
What sand mastic looks like in Four Oaks
Four Oaks is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St Mary's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Faversham station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Four Oaks: your questions answered
Do you cover smaller places like Four Oaks?
Yes, Four Oaks is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect sand mastic in Four Oaks?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
How long does sand mastic take to go off?
The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can I choose the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed for work to your windows.
When to call us in Four Oaks
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Signs it’s time to call us include:
- Gaps round a timber door in stone or brick
- Modern sealant on a period surround
- Wind and rain getting in round a sash window
- Old sand mastic that has cracked, crumbled or fallen out
Managing a site like Luddenham School? Then its window and door frames need their mastic kept sound, just like a home’s.

Different surfaces, different methods
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
