Maresfield Sand Mastic
We cover Maresfield for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps where the frame meets the masonry
- Draughty sash windows at the surround
What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Maresfield, 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.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit

Advice
Sand mastic in Maresfield, done properly
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. Common call-outs are for cracked mastic round a front door frame and draughty sash windows at the surround, across tenement windows, timber door frames and brick reveals.
Somewhere as small as Maresfield, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Big or small, you get the same one-year guarantee in Maresfield and across East Sussex.

Why act early in Maresfield
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. In a small place like Maresfield, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we’ll talk you through it.

Frames and glazing around Maresfield
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Bonners CofE School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as The Parish Church of St Bartholomew, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
