About our sand mastic in Little Heath
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. If you’re dealing with draughty sash windows at the surround and old cement repairs round a window that have failed, we can help, on stone surrounds, period & listed homes and sash and case windows alike.
Houses in smaller places like Little Heath can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Big or small, you get the same one-year guarantee.

Different surfaces, different methods
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Period and listed homes
Period homes look their best with traditional materials.
Little Heath homes and the weather
With historic houses such as Valentines Mansion (about 2.6 miles west) nearby, there’s older building stock in the area around Little Heath 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Chadwell Heath station change hands often, and any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Grove Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Mark's, the joint between an old wall and a newer frame is generally the first place rain gets in.

DIY sealant or a professional job?
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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

The process
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a single window, longer for several. Parking around Little Heath is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Let us know about parking restrictions
- Mention if the joints have been sealed before
- Mention any tricky access

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Sort the mastic before the decorators arrive
- Make sure water runs off the sill
- Have rotten timber repaired before new mastic goes in
- Find out about consent before window work on a listed home
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.

Why it’s worth doing now in Little Heath
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. Homes in smaller places like Little Heath can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
