How we handle sand mastic in Stratford St Mary
Across Stratford St Mary, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on tenement windows, brick reveals and period & listed homes, and common reasons people get in touch are gaps between timber frames and stone or brick and gaps round a timber door in stone or brick.
Somewhere as small as Stratford St Mary, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job, whatever its size.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Inspect the joints round the windows every year or so
- Make sure water runs off the sill
- Ask a joiner to look at soft timber first
- Ask us before painting near the mastic
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.

Why deal with it now?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. Older cottages and farmhouses around Stratford St Mary can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What affects the cost of sand mastic
We quote each job individually. This is what makes a difference:
- The old material and how stubborn it is
- Mould in or behind the old joints
- The number of rooms or windows
- Any working-time requirements on site
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- The address or postcode of the job

What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It generally takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Stratford St Mary, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed

Sand mastic in Stratford St Mary: local notes
With historic houses such as Castle House (about 1.7 miles south-east) nearby, there’s older building stock in the area around Stratford St Mary as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.

What we’re called out for in Stratford St Mary
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
If you can see any of these, it’s time to have the joints looked at:
- Old cement repairs round a window that have failed
- Cracked mastic round a front door frame
- Crumbling sand mastic round a window
- Mastic that needs renewing before redecorating
In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before you book
- What preparation is included
- How much experience the applicator has
- How the colour is chosen
- Is the old sealant removed completely?
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
