Why act early in East Donyland
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. Where a wall is exposed, as many are in small places like East Donyland, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

About our sand mastic in East Donyland
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. We work on timber door frames, stone surrounds and brick reveals, and people most often call us about cracked mastic round a front door frame and draughty sash windows at the surround.
Around East Donyland, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

Surface by surface
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Ask a joiner to look at soft timber first
- Clear gutters so water doesn’t pour onto the windows
- Go gently near the mastic when preparing windows
- Check with your local planning authority if your home is listed
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours per window, depending on the condition of the joints. In a small place like East Donyland, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- 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.
How to prepare
- Clear the area around the work
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

FAQs for East Donyland
I let a flat near Wivenhoe station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Is sand mastic in a coastal place like East Donyland any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Should I use sand mastic or silicone?
We will talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is it possible to take out silicone and use sand mastic instead?
Yes. We remove the silicone and clean the joint, then point it with sand mastic.
Do you guarantee sand mastic work?
You get our 12-month guarantee on every job.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.

Windows and doors in East Donyland
East Donyland is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like St Lawrence Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Church of St Lawrence, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
