Sand Mastic in Mogador
Sand mastic across Mogador and nearby, with old sealant always removed completely and a 12-month guarantee.
- Gaps round a timber door in stone or brick
- Patchy fillers round a sash window
- Mastic dropping out of the joint
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
How we handle sand mastic in Mogador
We work across Mogador renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. Typical jobs include gaps between timber frames and stone or brick and mastic worn away on windows facing the weather, across timber door frames, stone surrounds and period & listed homes.
Homes in small places like Mogador often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, it’s backed by our one-year guarantee.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look over the window mastic once a year
- Check with your local planning authority if your home is listed
- Go gently near the mastic when preparing windows
- Ask us before painting near the mastic
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
How the visit works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. It normally takes a few hours per window, depending on the condition of the joints. Somewhere like Mogador needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check the window surrounds and agree which joints need renewing.
- 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.
Getting ready for the visit

When to call us in Mogador
Timber frames move with the seasons. The movement cracks the mastic little by little.
The most common problems we see are:
- Open joints round the window box
- Mastic dropping out of the joint
- Mastic worn away on windows facing the weather
- Wind and rain getting in round a sash window
For an older house near a landmark such as Church of Jesus Christ and the Wisdom of God, the joint between an old wall and a newer frame is generally the first place rain gets in.

Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Stone surrounds
Old stone surrounds are often uneven, so the gap isn’t the same all the way round. Sand mastic is shaped by hand to suit.
