Sand mastic in Nutbourne, 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. Like-for-like sand mastic is often the preferred finish. If you are dealing with crumbling sand mastic round a window and draughty sash windows at the surround, we can put it right.
In a village or hamlet like Nutbourne, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Do I need permission for sand mastic on a listed building?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish, but they decide.
Should I use sand mastic or silicone?

What we do, step by step
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere like Nutbourne needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.

DIY versus a professional finish
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.
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.
Why act early in Nutbourne
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. Where a wall is exposed, as many are in small places like Nutbourne, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Frames and glazing around Nutbourne
Nutbourne is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
Rented homes near Nutbourne station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around St Wilfrid's Church and Hall, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Aftercare tips
A little care helps the new joints last. We recommend:
- Ask a joiner to look at soft timber first
- Keep sills and gutters clear so water drains away
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.

Do you need sand mastic in Nutbourne?
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Keep an eye out for any of the following:
- Cement or filler used on old window joints that has cracked
- Draughts and rain around sash boxes
- A silicone bead on a sash window that spoils the look
- Weathered mastic on the most exposed windows
For site and facilities teams at buildings such as Chidham Parochial Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
