Sand mastic for homes and businesses in Parker's Green
Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We work on brick reveals, sash and case windows and stone surrounds, and people most often call us about patchy fillers round a sash window and window mastic to renew ahead of painting.
Outdoor sealant needs dry, clean surfaces, so work on frames around Parker's Green is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Every job comes with our 12-month guarantee.

Questions from Parker's Green
Will you come out to Parker's Green?
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.
Can you do sand mastic in Parker's Green?
Yes, Parker's Green is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and shaped to suit the surround.
What do you need from me for a quote?
Tell us what needs doing and where, with pictures by email if possible. We will ask anything else we need to know.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
What guarantee comes with the work?
Our one-year guarantee covers every job.
Is it possible to take out silicone and use sand mastic instead?
Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Do not paint over the new mastic
- Sort the mastic before the decorators arrive
- Check the mastic when you check the paintwork
- Clear gutters so water doesn’t pour onto the windows
Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
What we are called out for in Parker's Green
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber and we normally remove them.
People usually contact us after spotting one of these:
- Wind and rain getting in round a sash window
- Mastic round period door frames that has failed
- Cement or filler used on old window joints that has cracked
- Crumbling sand mastic round a window
Rented homes near Tonbridge station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
Before booking anyone
- When the joint can take water or movement
- How the surfaces are prepared before sealing
- What product goes in the joint
- Whether you can choose the colour
Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. In a small place like Parker's Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

Different surfaces, different methods
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
When something else is needed
To be straight with you, some problems need a different trade:
- Sashes that need overhauling
- Damaged stone surrounds
- Broken panes
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.

Sand mastic in Parker's Green: local notes
With historic houses such as Old Soar Manor (about 3.4 miles north) nearby, there’s older building stock in the area around Parker's Green as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St Andrew include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Woodlands Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What we do, step by step
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours per window, depending on the condition of the joints for a typical job. Somewhere as small as Parker's Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Let us know about parking restrictions
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work
