Sand mastic in Warblington, done properly
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. We work on tenement windows, stone surrounds and brick reveals, and common reasons people get in touch are old cement repairs round a window that have failed and mastic worn away on windows facing the weather.
Outdoor sealant needs dry, clean surfaces, so work on frames around Warblington is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Do you need sand mastic in Warblington?
Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.
People normally contact us when they notice something like this:
- Gaps where the frame meets the masonry
- Mastic worn away on windows facing the weather
- Patchy fillers round a sash window
- Draughts and rain around sash boxes
In the older streets around St Thomas à Becket Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Is sand mastic better than silicone for my windows?

Do I have to be there?

What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and finished to sit neatly against the masonry.

Advice
Also in Warblington
Why deal with it now?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Where a wall is exposed, as many are in small places like Warblington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

Windows and doors in Warblington
Warblington is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Warblington Castle (about 0.4 miles north-east) nearby, there’s older building stock in the area around Warblington 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.
For landlords with property near Warblington station, any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Bosmere Junior School, the mastic around its windows and doors needs looking after like any other building’s.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
