Sand mastic in Itchen Abbas
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on brick reveals, timber door frames and stone surrounds, and the jobs we see most are mastic that needs renewing before redecorating and cracked mastic round a front door frame.
Outdoor sealant needs dry, clean surfaces, so work on frames around Itchen Abbas is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Every job is covered by a 12-month guarantee, wherever you are in Hampshire.

Itchen Abbas homes and the weather
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.
Homes close to Church of St John the Baptist include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Winchester station, any sash windows need sound mastic to keep draughts and rain out.

Where are you based?
Mr Mastic is based in Crawley. We cover Itchen Abbas and the rest of Hampshire, along with the rest of our area.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient.
Do you have insurance?
Yes, we are fully insured for domestic and commercial work.
Do you need sand mastic in Itchen Abbas?
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
The most common problems we see are:
- Window mastic to renew ahead of painting
- Cracked mastic round a front door frame
- Gaps between timber frames and stone or brick
- Draughts and rain around sash boxes
Schools such as Itchen Abbas Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How the job changes by surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

The process
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows for a typical job.

- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.

When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Timber that has rotted
- Masonry that needs repairing
- Decisions on consent for listed homes
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before you book.
Surfaces we seal
- Tenement windows
- Timber door frames
- Period & listed homes
- Stone surrounds
- Brick reveals
- Sash and case windows
Leave it or put it right?
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 Itchen Abbas, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
