Shippon Sand Mastic

About our sand mastic in Shippon
Across Shippon, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on tenement windows, sash and case windows and timber door frames, and common reasons people get in touch are silicone on a period window that looks wrong and gaps between timber frames and stone or brick.
Homes in small places like Shippon 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.
Big or small, it’s backed by our 12-month guarantee in Shippon and across Oxfordshire.

What affects the cost of sand mastic
Call for a quick quote. The main things that affect it are:
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The amount of work
- Which sealant suits the joint
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. You will know the price before we begin.
Helping us quote
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- The rough size of the job
- Photos by email, if that’s easy
- Any access issues, like height or stairs
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or drop us an email.
Leave it or put it right?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In a small place like Shippon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us.
Why us?
- Anti-fungal silicone where joints get wet
- We leave the area clean and tidy
- Experience in homes, commercial sites and hotels
- More than 20 years in sealant work

Shippon questions
Do you cover smaller places like Shippon?
Yes, Shippon 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 Shippon for sand mastic?
Yes. Our work covers London and the South East, and Shippon is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.
Do you offer different sealant colours?
Most of the time, yes. We will tell you which colours the right product comes in.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or email us.
When will the new mastic be hard?
The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.
Are you fully insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
For anyone letting property in or around Shippon, several properties can be quoted together. Send us the addresses and the work at each.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a single window, longer for several. In a small place like Shippon, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
- Clear the area around the work

What the job involves on each surface
Stone surrounds
The stone is treated with care while raking out the old mastic.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Do you need sand mastic in Shippon?
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
People generally contact us after spotting one of these:
- Old sand mastic that has cracked, crumbled or fallen out
- Draughty sash windows at the surround
- A silicone bead on a sash window that spoils the look
- Tired mastic found when preparing windows for paint
Homes close to Church of St Mary Magdalene include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- What guarantee comes with the work
- What happens if the job turns out different
- Whether the sealant suits the joint

What else we do in Shippon
Windows and doors in Shippon
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Appleton Manor (about 3.1 miles north-west) are a reminder that the area around Shippon 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 Radley station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Larkmead School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
