Sand mastic in Ashley, done properly
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. We work on tenement windows, timber door frames and sash and case windows, and people most often call us about crumbling sand mastic round a window and draughty sash windows at the surround.
Around Ashley, 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.
We stand behind the work with a 12-month guarantee.

How to look after the new joints
After the cure time, these simple habits help:
- Sort the mastic before the decorators arrive
- Clear gutters so water doesn’t pour onto the windows
- Look over the window mastic once a year
- Ask a joiner to look at soft timber first
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Common problems we fix in Ashley
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.
Signs it’s time to call us include:
- A silicone bead on a sash window that spoils the look
- Old sand mastic that has cracked, crumbled or fallen out
- Draughty sash windows at the surround
- Open joints round the window box
If you live in an older home near East Studdal Church Hall, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Ashley homes and the weather
Historic houses like Walmer Castle (about 4.3 miles east) are a reminder that the area around Ashley has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among 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 let a flat or house near Martin Mill station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Why it’s worth doing now in Ashley
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In a small place like Ashley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to a full day, depending on how many windows. In a small place like Ashley, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property

When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Planning or listed building consent (your local planning authority decides)
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.
