Sand mastic in Chilgrove
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on period & listed homes, sash and case windows and brick reveals, and common reasons people get in touch are window mastic to renew ahead of painting and gaps where the frame meets the masonry.
Homes in small places like Chilgrove often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, in Chilgrove and everywhere else we cover.

What affects the quote in Chilgrove
Every job gets its own quote. These are the things that affect it:
- How easy the joints are to reach
- Any working-time requirements on site
- How much there is to do
- The product the joint needs
The cost depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
Asking for a quote
Before you ask for a quote, have a think about:

Chilgrove homes and the weather
With historic houses such as West Dean House (about 1.6 miles south-east) nearby, there’s older building stock in the area around Chilgrove as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Chilgrove, as everywhere, sand mastic is only as good as the preparation behind it. West Dean House, about 1.6 miles south-east, is one of the historic houses in the wider area around Chilgrove.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to a full day, depending on how many windows, and the area is left clean. For a village or hamlet like Chilgrove, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Mention any tricky access
- Mention any parking rules near the property
- Keep children and pets away from the work area
How to get a quote

What the job involves on each surface
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Brick reveals
Loose mastic comes out and deep gaps are packed before the new mastic goes in.
Why deal with it now?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. Where a wall is exposed, as many are in small places like Chilgrove, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.
Why book with us
- Tidy, careful work
- Arbo and Everbuild products
- Old sealant always removed completely
- More than 20 years in sealant work

Your questions about sand mastic in Chilgrove
Can you do sand mastic in Chilgrove?
Yes. Our work covers London and the South East, and Chilgrove is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Is there a guarantee on sand mastic in Chilgrove?
All our work, in Chilgrove and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
How to look after the new joints
After the cure time, these simple habits help:
- Don’t run silicone over sand mastic
- Check with your local planning authority if your home is listed
- Renew mastic before redecorating the windows
- Make sure water runs off the sill
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
