Sand mastic in Sturry, done properly
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. If you have gaps where the frame meets the masonry and mastic round period door frames that has failed, we can help, on brick reveals, stone surrounds and period & listed homes alike.
In a smaller place like Sturry, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.
Whatever the size of the job, you get the same 12-month guarantee in Sturry and across Kent.

The process
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours per window, depending on the condition of the joints for a typical job. A visit to Sturry is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit

Frames and glazing around Sturry
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to St Nicholas' Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Sturry station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Sturry Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Aftercare tips
Aftercare is simple:
- Avoid patching sand mastic with silicone
- Renew mastic before redecorating the windows
- Go gently near the mastic when preparing windows
- Clear gutters so water does not pour onto the windows
Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Leave it or put it right?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Around Sturry, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

Can you help a landlord with a rental near Sturry station?

Is the work guaranteed?
Our 12-month guarantee applies on every job.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we’ll advise.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
What affects the quote in Sturry
Every job gets its own quote. These are the things that affect it:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- When we can work, for business premises
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- The rough size of the job
- If someone has resealed it before
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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.
