About our sand mastic in Kings Hill
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. We work on timber door frames, brick reveals and period & listed homes, and the jobs we see most are mastic dropping out of the joint and weathered mastic on the most exposed windows.
In smaller places like Kings Hill, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

What sand mastic looks like in Kings Hill
With historic houses such as Old Soar Manor (about 3.7 miles west) nearby, there’s older building stock in the area around Kings Hill 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. 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.
Schools such as Kings Hill School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near West Malling station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Church of St John the Baptist, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Kings Hill questions
Do you cover Kings Hill for sand mastic?
Yes, Kings Hill is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Is Kings Hill within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in.
Should I use sand mastic or silicone?
That depends on your windows. On many period windows, sand mastic looks right and suits the building and newer frames generally get a flexible sealant.
What does sand mastic cost?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or email us with a short description of the job.
Can you seal over the old sealant?
No. The old sealant always comes out first.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
Letting agents and landlords in Kings Hill can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for.
What happens if it’s left?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. In a smaller place like Kings Hill, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating. The job usually takes anything from a few hours to a full day, depending on how many windows, and we tell you how long to leave it before we go. A visit to Kings Hill is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Before we arrive
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints
- Mention if the joints have been sealed before

How the job changes by surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Inspect the joints round the windows every year or so
- Have rotten timber repaired before new mastic goes in
- Clear gutters so water does not pour onto the windows
- Don’t run silicone over sand mastic
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
What we can’t put right
It helps to know what we can’t do too:
- Sash cords, weights and draught-proofing of the sashes
- Damaged stone surrounds
- Broken panes
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.
