Sand mastic in Phoenix Green, done properly
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on sash and case windows, timber door frames and brick reveals, and the jobs we see most are old cement repairs round a window that have failed and gaps between timber frames and stone or brick.
Homes in small places like Phoenix Green 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.
You get a one-year guarantee, the same in Phoenix Green as everywhere else we work.

How we quote for sand mastic
Every job gets its own quote. This is what makes a difference:
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- The number of rooms or windows
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- How we’d reach the joints
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
How to look after the new joints
So the new joints stay in good condition:
- Don’t paint over the new mastic
- Avoid heavy scraping on the mastic joint
- Make sure water runs off the sill
- Inspect the joints round the windows every year or so
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
What we’re called out for in Phoenix Green
Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.
People usually contact us when they notice one of these:
- Wind and rain getting in round a sash window
- Gaps where the frame meets the masonry
- Old sand mastic that has cracked, crumbled or fallen out
- Cement or filler used on old window joints that has cracked
If you live in an older home near St Mary's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before booking anyone
- Whether VAT is included
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
- Who does the work, and how experienced they are
Landlords, agents and businesses in Phoenix Green
For anyone letting property in or around Phoenix Green, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
The process
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Phoenix Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

Can I do it myself?
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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Windows and doors in Phoenix Green
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Greenfields Junior School, larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Winchfield station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.
