How we handle sand mastic in Edenbridge
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you have cracked mastic round a front door frame and window mastic to renew ahead of painting, we can help, whatever the surface.
Homes around Edenbridge range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What else we do in Edenbridge
What sand mastic looks like in Edenbridge
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hever Castle (about 2.4 miles south-east) are a reminder that the area around Edenbridge has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Edenbridge Town station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near Church of St Peter and St Paul, the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as Edenbridge Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Leave it or put it right?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a smaller place like Edenbridge, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The process
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to a full day, depending on how many windows. A visit to Edenbridge 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 look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed

Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Is Edenbridge in your area for sand mastic?
Yes. Our work covers London and the South East, and Edenbridge is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Should I use sand mastic or silicone?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
What is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
How long does sand mastic take to go off?
It takes a while. The skin forms first, and the full set comes later, and we will tell you what to expect.
How to look after the new joints
So the new joints stay in good condition:
- Take care around the mastic when scraping paint
- Look over the window mastic once a year
- Find out about consent before window work on a listed home
- Get any rot dealt with first
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
