About our sand mastic in Remenham Hill
We work across Remenham Hill renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. We are often asked to deal with weathered mastic on the most exposed windows and window mastic to renew ahead of painting, across tenement windows, brick reveals and timber door frames.
In a village or hamlet like Remenham Hill, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Every job is covered by our one-year guarantee.

Questions from Remenham Hill
I let a flat near Henley-On-Thames station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Is Remenham Hill in your area for sand mastic?
Yes, Remenham Hill is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Is sand mastic better than silicone for my windows?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They decide whether consent is needed for work to your windows.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Landlords and agents in Remenham Hill can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
What sand mastic looks like in Remenham Hill
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. With historic houses such as Greenlands (about 1.7 miles north) nearby, there’s older building stock in the area around Remenham Hill as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St Nicholas include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Rupert House School, its window and door frames need their mastic kept sound, just like a home’s.

Leave it or put it right?
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 Remenham Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
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. The price is agreed before we begin.
Why us?
- Every job guaranteed for a year

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Get any rot dealt with first
- Ask the planning authority about consent for listed or conservation-area homes
- Don’t run silicone over sand mastic
- Ask us before painting near the mastic
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
How the job changes by surface
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
