Sand mastic in Hookwood, done properly
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we will advise if you’re redecorating. We work on tenement windows, brick reveals and period & listed homes, and people most often call us about cement or filler used on old window joints that has cracked and modern sealant on a period surround.
Homes in small places like Hookwood often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Sand mastic in Hookwood: local notes
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.
For an older house near a landmark such as Church of St Bartholomew, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Horley station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Manorfield Primary and Nursery School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Why it’s worth doing now in Hookwood
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Where a wall is exposed, as many are in small places like Hookwood, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- Full insurance on every job
- Old sealant always removed completely
- 4.9 on Google from 180+ five-star reviews

For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What affects the quote in Hookwood
The price is agreed before any work begins. It’s based on:
- The number and length of the joints
- The number of rooms or windows
- The type of sealant required
- Working hours on commercial sites
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- The address or postcode of the job
- Whether it’s a home or a business
- Any previous sealing or DIY work
