Sand mastic for sash & case windows in Conford, Hampshire
Window and door surrounds in Conford need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Weathered mastic on the most exposed windows
- Draughty sash windows at the surround
- Tired mastic found when preparing windows for paint
How we handle sand mastic in Conford
Across Conford, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. Common call-outs are for draughty sash windows at the surround and gaps where the frame meets the masonry, across brick reveals, stone surrounds and sash and case windows.
Around Conford, 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.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or email us.

What the job involves on each surface
Brick reveals
An open joint at a brick reveal lets weather in. 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.
What sealant work cannot fix
New sealant can’t fix everything, and we’ll tell you before work begins. It won’t solve:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Damaged stone surrounds
- Decisions on consent for listed homes
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal
- Tenement windows
- Timber door frames
- Period & listed homes
- Stone surrounds
- Brick reveals
- Sash and case windows
Common problems we fix in Conford
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
Any of these means the joints need attention:
- Gaps between timber frames and stone or brick
- Modern sealant on a period surround
- Window mastic to renew ahead of painting
- Patchy fillers round a sash window

Frames and glazing around Conford
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Liphook Infant School, larger buildings have plenty of frames, and the mastic around each one ages.

How it works
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes a few hours per window, depending on the condition of the joints in most cases. In a small place like Conford, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- 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.
- The mastic is finished to sit tidily against the stone or brick.

Advice
Questions from Conford
Can you do sand mastic in Conford?
Yes, Conford is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Conford?
Yes. Conford is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Is sand mastic better than silicone for my windows?
Sand mastic normally suits period timber windows best. Modern frames normally suit a flexible sealant, and we will explain why.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Conford.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we’ll advise.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Why act early in Conford
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new work lasts. Where a wall is exposed, as many are in small places like Conford, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
