Do you need sand mastic in Hurst Green?
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Look out for these signs:
- Old cement repairs round a window that have failed
- Failed mastic on an exposed elevation
- Gaps where the frame meets the masonry
- Tired mastic found when preparing windows for paint
Schools such as Hurst Green Church of England Primary School and Nursery are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Sand mastic in Hurst Green
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you are dealing with patchy fillers round a sash window and gaps round a timber door in stone or brick, we can put it right, on sash and case windows, period & listed homes and tenement windows alike.
Around Hurst Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for a single window, longer for several, depending on how much there is to do. Somewhere like Hurst Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
How to prepare
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in

Advice
FAQs for Hurst Green
I let a flat near Etchingham station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Do you cover smaller places like Hurst Green?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you offer different sealant colours?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before we start.
When will the new mastic be hard?
It takes a while. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish, but they decide.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
Surface by surface
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Why act early in Hurst Green
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. In a small place like Hurst Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Frames and glazing around Hurst Green

Historic houses like Bateman's (about 4.4 miles south-west) are a reminder that the area around Hurst Green has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Etchingham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. In the older streets around Holy Trinity, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Looking after it afterwards
After the cure time, these simple habits help:
- Ask a joiner to look at soft timber first
- Take care around the mastic when scraping paint
- Check with your local planning authority if your home is listed
- Do not run silicone over sand mastic
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
