About our sand mastic in Great Holland
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We work on stone surrounds, sash and case windows and tenement windows, and the jobs we see most are patchy fillers round a sash window and mastic dropping out of the joint.
Around Great Holland, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Avoid heavy scraping on the mastic joint
- Do not paint over the new mastic
- Check with your local planning authority if your home is listed
- Look over the window mastic once a year
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
Great Holland homes and the weather
Great Holland is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. With historic houses such as Thorpe Hall (about 2.2 miles north-west) nearby, there’s older building stock in the area around Great Holland as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as Kirby Primary Academy, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of All Saints include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Advice
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
FAQs for Great Holland
Does the coastal weather in Great Holland affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Great Holland?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you have insurance?
Yes, we’re fully insured for domestic and commercial work.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Is there any odour?
Some sealants have a smell while they cure. Opening a window helps.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What guarantee comes with the work?
All our work has a 12-month guarantee.
Can I choose the sealant colour?
Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
What the job involves on each surface
Tenement and terrace windows
Upper-floor windows need access planning. Let us know the floor and we will confirm access.
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Do you need sand mastic in Great Holland?
Shallow joints are a common cause. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
If you can see any of these, it’s time to have the joints looked at:
- Weathered mastic on the most exposed windows
- Window mastic to renew ahead of painting
- Draughts and rain around sash boxes
- Mastic round period door frames that has failed
Letting a property close to Kirby Cross station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
