Sand mastic for homes and businesses in Chase Cross
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 replace one with the other. Typical jobs include old cement repairs round a window that have failed and cracked mastic round a front door frame, on sash and case windows, timber door frames and tenement windows.
In a smaller place like Chase Cross, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

When to call us in Chase Cross
Rain on the window surround works into any crack and pushes it out. Exposed elevations normally fail first.
Look out for these signs:
- A silicone bead on a sash window that spoils the look
- Mastic that needs renewing before redecorating
- Patchy fillers round a sash window
- Mastic dropping out of the joint
If you look after a building such as Bower Park Academy, the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- How hidden problems are handled
- Which colour the sealant will be
- What insurance they hold
- Whether all the old sealant comes out first
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Make sure water runs off the sill
- Have rotten timber repaired before new mastic goes in
- Go gently near the mastic when preparing windows
- Inspect the joints round the windows every year or so
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
Surface by surface
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
Leave it or put it right?
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. Homes in smaller places like Chase Cross can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.

Sand mastic in Chase Cross: local notes
With historic houses such as Hare Hall (about 2 miles south-east) nearby, there’s older building stock in the area around Chase Cross 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 James include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. Rented homes near Gidea Park station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
