About our sand mastic in Little Walden
Across Little Walden, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. If you have modern sealant on a period surround and draughty sash windows at the surround, we can put it right, on period & listed homes, tenement windows and stone surrounds alike.
Homes in small places like Little Walden 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.
Whatever the size of the job, it’s backed by our one-year guarantee.

Windows and doors in Little Walden
With historic houses such as Audley End House (about 2.5 miles south-west) nearby, there’s older building stock in the area around Little Walden as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

What affects the quote in Little Walden
We quote each job individually. These are the things that affect it:
- Mould in or behind the old joints
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- Access and height
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- Where the property is
- The rough size of the job
- If someone has resealed it before
To get a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before work begins.
What happens if it’s left?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Little Walden, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

What else we do in Little Walden
What we are called out for in Little Walden
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Any of these means the joints need attention:
- Modern sealant on a period surround
- Mastic round period door frames that has failed
- Old cement repairs round a window that have failed
- Gaps between timber frames and stone or brick
Schools such as Saffron Walden County High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- How long to leave it before use
- Which colour the sealant will be
- Whether they’re fully insured
- How hidden problems are handled
How the job changes by surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a single window, longer for several. For a village or hamlet like Little Walden, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
