About our sand mastic in Risinghurst
Across Risinghurst, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you are dealing with open joints round the window box and window mastic to renew ahead of painting, we can help.
Many houses in smaller places like Risinghurst have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How we quote for sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- Whether there’s mould to deal with
- Which sealant suits the joint
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.
What we need to know
When you contact us, these details help:
- If someone has resealed it before
- The rough size of the job
- The address or postcode of the job
- The type of property
Asking for a quote is easy: tell us what needs doing and where. A few photos by email make the job easier to understand, and we’ll take it from there.
Common problems we fix in Risinghurst
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint, and they usually need raking out.
These are the problems we are asked about most:
- Old sand mastic that has cracked, crumbled or fallen out
- Modern sealant on a period surround
- Mastic round period door frames that has failed
- Patchy fillers round a sash window
Letting a property close to Oxford station? Then any sash windows need sound mastic to keep draughts and rain out.
What to look for in a quote
- How the colour is chosen
- When the joint can take water or movement
- Whether all the old sealant comes out first
- Whether VAT is included
Why it’s worth doing now in Risinghurst
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In a smaller place like Risinghurst, 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.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.

Risinghurst homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Holywell Manor (about 2.5 miles west) are a reminder that the area around Risinghurst 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 is traditional sand mastic.
Managing a site like Bayards Hill School? Then its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Parish Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How the visit works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a single window, longer for several. A visit to Risinghurst is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each surround is checked first.
- The joint is raked out and cleaned.
- 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.
Preparing for the visit
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

Advice
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What the job involves on each surface
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.

How much does sand mastic cost in Risinghurst?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Inspect the joints round the windows every year or so
- Plan mastic work ahead of painting
- Find out about consent before window work on a listed home
- Avoid patching sand mastic with silicone
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
