Sand mastic for homes and businesses in Shawford
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 have gaps round a timber door in stone or brick and failed mastic on an exposed elevation, we can help.
Around Shawford, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All our work comes with our one-year guarantee, wherever you are in Hampshire.

What affects the quote in Shawford
The quote reflects the job in front of us. We look at:
- The old material and how stubborn it is
- How many areas need sealing
- The size of the job
- Any working-time requirements on site
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Pictures of the joints, sent by email
- Roughly how big the job is
- Where the property is
- Any access issues, like height or stairs
For sand mastic in Shawford, phone 0345 464 0079 or email us. Tell us what the problem is and where, and you will get a clear quote before any work starts.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What happens on the day
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a single window, longer for several. In a small place like Shawford, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Mention any tricky access
- Tell us if parking is tricky
- Clear the area around the work

Advice
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Get any rot dealt with first
- Keep sills and gutters clear so water drains away
- Go gently near the mastic when preparing windows
- Ask us before painting near the mastic
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
Sand mastic in Shawford: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Compton All Saints Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Shawford station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
