Professional sand mastic in and around Mill Street, with old sealant always removed completely.
- Gaps round a timber door in stone or brick
- Open joints round the window box
- Tired mastic found when preparing windows for paint
What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a single window, longer for several. Somewhere like Mill Street 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 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.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

Advice
How we handle sand mastic in Mill Street
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Typical jobs include gaps between timber frames and stone or brick and wind and rain getting in round a sash window, across stone surrounds, period & listed homes and sash and case windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Mill Street is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What else we do in Mill Street
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep modern sealant off the mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Clear gutters so water doesn’t pour onto the windows
- Take care around the mastic when scraping paint
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.
Mill Street homes and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Stoke-by-Nayland Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What happens if it’s left?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Around Mill Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Do you need sand mastic in Mill Street?
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
The problems people usually mention when they call include:
- Gaps between timber frames and stone or brick
- Failed mastic on an exposed elevation
- Wind and rain getting in round a sash window
- Mastic round period door frames that has failed
Homes close to Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- How the surfaces are prepared before sealing
- What happens if they find a problem under the old sealant
- What the cure time is
- Is VAT in the price?
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
