Sand mastic in Hook Norton
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead and we will explain which is best for yours. We work on timber door frames, period & listed homes and brick reveals, and common reasons people get in touch are silicone on a period window that looks wrong and draughts and rain around sash boxes.
Houses in smaller places like Hook Norton can stand more in the open than those in a built-up town. That is hard on the mastic around frames and sills.
There’s a 12-month guarantee on every job, whatever its size.

Why deal with it now?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. In a smaller place like Hook Norton, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us and we’ll talk you through it.

FAQs for Hook Norton
Is sand mastic in Hook Norton guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Hook Norton?
Yes, Hook Norton is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long does the job take?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Bigger jobs take longer, and we’ll tell you how long to expect.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic beds in well.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.

What affects the cost of sand mastic
Jobs vary more than people expect. What affects the quote:
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
- Working hours on commercial sites
- The product the joint needs
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.
What we need to know
When you call or email, it’s useful to know:
- How we’d reach the joints
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Look over the window mastic once a year
- Find out about consent before window work on a listed home
- Avoid patching sand mastic with silicone
- Get any rot dealt with first
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours per window, depending on the condition of the joints. For a job in Hook Norton, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Mention any tricky access
- Keep children and pets away from the work area
- Tell us if parking is tricky

Frames and glazing around Hook Norton
Historic houses like Broughton Castle (about 4.8 miles north-east) are a reminder that the area around Hook Norton has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Peter include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
