Sand mastic in Stratfield Mortimer, done properly
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We work on sash and case windows, stone surrounds and timber door frames, and common reasons people get in touch are patchy fillers round a sash window and silicone on a period window that looks wrong.
Around Stratfield Mortimer, 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.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Why act early in Stratfield Mortimer
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. Where a wall is exposed, as many are in small places like Stratfield Mortimer, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

How the job changes by surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Keeping the joints in good condition
Looking after new joints is easy:
- Have rotten timber repaired before new mastic goes in
- Ask us before painting near the mastic
- Avoid heavy scraping on the mastic joint
- Find out about consent before window work on a listed home
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.

Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Do you need sand mastic in Stratfield Mortimer?
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
The problems people generally mention when they call include:

Sand mastic in Stratfield Mortimer: local notes
With historic houses such as Stratfield Saye House (about 2.7 miles south-east) nearby, there’s older building stock in the area around Stratfield Mortimer as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Mortimer St Mary's C.E. Junior School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Saint John The Evangelist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
