When it is not the sealant

- Crumbling stone or brickwork round the window
- Sash cords, weights and draught-proofing of the sashes
- Planning or listed building consent (your local planning authority decides)

Sand mastic in North Fareham, done properly
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we will advise if you are redecorating. We are often asked to deal with mastic dropping out of the joint and mastic round period door frames that has failed, across sash and case windows, brick reveals and timber door frames.
Around North Fareham, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

FAQs for North Fareham
Does living near the coast affect sand mastic in North Fareham?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Fareham station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
How much does sand mastic cost in North Fareham?
Size, access and the old material all affect the cost. Ask us for a quote.
Can old silicone round a sash window be swapped for sand mastic?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Make sure water runs off the sill
- Have rotten timber repaired before new mastic goes in
- Plan mastic work ahead of painting
- Do not paint over the new mastic
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

What the job involves on each surface
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we will confirm access.
How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours per window, depending on the condition of the joints, and the area is left clean. Somewhere as small as North Fareham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Mention if the joints have been sealed before
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Advice
Windows and doors in North Fareham
North Fareham is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces 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.
If you let a flat or house near Fareham station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like Harrison Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Parish Church of St Peter and St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
