Sand mastic in East Peckham, done properly
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. If you have mastic worn away on windows facing the weather and gaps between timber frames and stone or brick, we can put it right.
Homes in small places like East Peckham often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Leave it or put it right?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. Around East Peckham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Your questions about sand mastic in East Peckham
Do you cover smaller places like East Peckham?
Yes, East Peckham is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Beltring station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
How long does sand mastic take to harden?
Not right away. It skins first and hardens fully later, and we will tell you what to expect.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we will talk you through it.
Signs you need sand mastic in East Peckham
Sand mastic slowly weathers. It dries out, cracks and loses its grip on the stone or timber.
Any of these means the joints need attention:
- Mastic dropping out of the joint
- Mastic round period door frames that has failed
- Wind and rain getting in round a sash window
- Mastic worn away on windows facing the weather
Schools such as East Peckham Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Sand mastic in East Peckham: local notes
With historic houses such as Old Soar Manor (about 4.5 miles north-west) nearby, there’s older building stock in the area around East Peckham as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
If you let a flat or house near Beltring station, cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Church of the Holy Trinity, the joint between an old wall and a newer frame is usually the first place rain gets in.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Don’t paint over the new mastic
- Keep sills and gutters clear so water drains away
- Avoid patching sand mastic with silicone
- Check the mastic when you check the paintwork
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.

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 are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Different surfaces, different methods
Period and listed homes

Timber door frames
Round a period front door, sand mastic gives the right look.
How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. In a small place like East Peckham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
