Common problems we fix in Church Enstone
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
The most common problems we see are:
- Weathered mastic on the most exposed windows
- Old cement repairs round a window that have failed
- Silicone on a period window that looks wrong
- Cracked mastic round a front door frame
In the older streets around Church of St Kenelm, the joint between an old wall and a newer frame is generally the first place rain gets in.
Before you book anyone
- What product goes in the joint
- How much experience the applicator has
- Whether they seal over old material or remove it
- When the joint can take water or movement
How we handle sand mastic in Church Enstone
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on tenement windows, timber door frames and sash and case windows, and people most often call us about wind and rain getting in round a sash window and mastic round period door frames that has failed.
Around Church Enstone, 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.

The process
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a few hours for a single window, longer for several in most cases. Somewhere like Church Enstone needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided 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.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work

Why act early in Church Enstone
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. In a small place like Church Enstone, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

FAQs for Church Enstone
Is Church Enstone within the area you cover?

Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

It depends on the job. For work indoors, someone needs to let us in.

All our work has a one-year guarantee, and we’re fully insured.

Do you hold any approvals?

What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and shaped to suit the surround.
