About our sand mastic in Frimley
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on tenement windows, timber door frames and period & listed homes, and people most often call us about mastic dropping out of the joint and mastic round period door frames that has failed.
In a town like Frimley, the windows on the most exposed side of a house take the brunt of the rain, and that is usually where the sealant gives up first. It’s worth looking at every frame, not just the one that leaks.
Our work is backed for twelve months.

What sand mastic looks like in Frimley
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around St. Peter's Church, the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as Lakeside Primary School, its window and door frames need their mastic kept sound, just like a home’s.

The process
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a single window, longer for several. For a job in Frimley, we need access to where the work is and somewhere nearby to park. 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.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky

Leave it or put it right?
If you are redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. Black mould and gaps in sealant don’t fix themselves, and in a busy home in Frimley they get worse with every use. Replacing the sealant now is the simplest fix.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

What the job involves on each surface
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
When to call us in Frimley
Timber frames move with the seasons. The movement cracks the mastic little by little.
Most people get in touch after spotting one of these:

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
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 does not work out, we can still put it right.

Can sand mastic be painted?

Do you guarantee sand mastic work?

Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
How do I get a quote for sand mastic in Frimley?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Ask a joiner to look at soft timber first
- Avoid heavy scraping on the mastic joint
- Inspect the joints round the windows every year or so
- Ask us before painting near the mastic
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
