About our sand mastic in Wye
On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead and we’ll explain which is best for yours. If you are dealing with cracked mastic round a front door frame and mastic worn away on windows facing the weather, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Wye is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Why it’s worth doing now in Wye
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Where a wall is exposed, as many are in small places like Wye, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

Frames and glazing around Wye
Historic houses like Godinton House (about 4.8 miles west) are a reminder that the area around Wye 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. 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.
Homes close to Church of Saint Gregory and Saint Martin include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Lady Joanna Thornhill Endowed Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Surface by surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints. In a small place like Wye, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints

- Mastic that needs renewing before redecorating
- Cracked mastic round a front door frame
- Patchy fillers round a sash window
