Sand mastic in Duddleswell, done properly
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We are often asked to deal with gaps round a timber door in stone or brick and mastic that needs renewing before redecorating, across tenement windows, period & listed homes and sash and case windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Duddleswell is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job.

Why act early in Duddleswell
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. Around Duddleswell, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a single window, longer for several. Somewhere as small as Duddleswell, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
- Tell us if parking is tricky

Different surfaces, different methods
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Can I do it myself?
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
