Sand mastic for homes and businesses in Alfold Crossways
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it and we will advise if you are redecorating. If you’re dealing with window mastic to renew ahead of painting and cracked mastic round a front door frame, we can help, whatever the surface.
Around Alfold Crossways, 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 a 12-month guarantee.

What the job involves on each surface
Stone surrounds
Stone openings are rarely perfectly straight, so the gap isn’t the same all the way round. Sand mastic is shaped by hand to suit.
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It gives a traditional finish.
What happens on the day
The work is kept neat and contained to the joints we’re treating. The job normally takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Alfold Crossways, access is often the only tricky part. 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.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Let us know if you’ve seen damp or leaks

Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like, but they decide.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Why it’s worth doing now in Alfold Crossways
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Where a wall is exposed, as many are in small places like Alfold Crossways, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- We leave the area clean and tidy
- We never seal over old sealant
- 4.9 on Google from 180+ five-star reviews
- Anti-fungal sanitary silicone in wet areas

What we are called out for in Alfold Crossways
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber, and they normally need raking out.
Any of these means the joints need attention:
- Draughts and rain around sash boxes
- Patchy fillers round a sash window
- Gaps where the frame meets the masonry
- Crumbling sand mastic round a window
Around Alfold Crossways, as everywhere, sand mastic is only as good as the preparation behind it.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
