Sand mastic in Hinxton
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. If you are dealing with silicone on a period window that looks wrong and old sand mastic that has cracked, crumbled or fallen out, we can help, whatever the surface.
Homes in small places like Hinxton often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We stand behind the work with a 12-month guarantee.

FAQs for Hinxton
Is Hinxton within the area you cover?
Yes, Hinxton is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Hinxton for sand mastic?
Yes, Hinxton is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
Do you have insurance?
Yes. We’re fully insured.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Is sand mastic better than silicone for my windows?
It depends on the window. Period windows in stone or brick generally suit sand mastic, while modern frames normally get a flexible sealant.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we will advise.
Work for landlords, hotels and businesses
Landlords and agents in Hinxton can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
Why act early in Hinxton
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. In a small place like Hinxton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

The process
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. The work usually takes a few hours for a single window, longer for several. For a village or hamlet like Hinxton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work

Signs you need sand mastic in Hinxton
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
Look out for these signs:
- Mastic round period door frames that has failed
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
- Draughty sash windows at the surround
If you live in an older home near Parish Church of St Mary and St John the Evangelist, the joint between an old wall and a newer frame is usually the first place rain gets in.
Questions to ask before booking
- Who turns up on the day
- What insurance they hold
- How long to leave it before use
- Whether you can choose the colour
How to look after the new joints
After the cure time, these simple habits help:
- Avoid heavy scraping on the mastic joint
- Leave the new mastic unpainted
- Inspect the joints round the windows every year or so
- Ask a joiner to look at soft timber first
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
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, and the work is guaranteed for a year.

Hinxton homes and the weather
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. Historic houses like Audley End House (about 4.8 miles south) are a reminder that the area around Hinxton has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Whittlesford Parkway station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
