Sand mastic for homes and businesses in Strood
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. We work on tenement windows, sash and case windows and stone surrounds, and common reasons people get in touch are failed mastic on an exposed elevation and crumbling sand mastic round a window.
Strood mixes older streets, where windows have often been replaced, with newer estates fitted with uPVC. All of them depend on a sound bead of mastic between frame and wall.
All of our work is guaranteed for twelve months, in Strood and everywhere else we cover.

What sand mastic looks like in Strood
With historic houses such as Temple Manor (about 0.5 miles south-east) nearby, there’s older building stock in the area around Strood as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as St Francis' Church, the joint between an old wall and a newer frame is generally the first place rain gets in. Schools such as Elaine Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What happens on the day
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to a full day, depending on how many windows in most cases. A visit in Strood needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.

Different surfaces, different methods
Period and listed homes
Materials matter on listed and conservation-area homes. Like-for-like sand mastic is generally favoured.
Brick reveals
Loose mastic comes out and deep gaps are packed before the new mastic goes in.
Why act early in Strood
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Black mould and gaps in sealant do not fix themselves, and in a busy home in Strood they get worse with every use. Now is the easy time to put it right.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why Strood customers choose us
- Anti-fungal sanitary silicone in wet areas

How to look after the new joints
A little care helps the new joints last. Our advice:
- Clear gutters so water doesn’t pour onto the windows
- Inspect the joints round the windows every year or so
- Keep modern sealant off the mastic
- Do not paint over the new mastic
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
