Sand Mastic in Bethersden
Window and door surrounds in Bethersden need attention? We remove the old material, prepare the joints and seal them properly.
- Old cement repairs round a window that have failed
- Crumbling sand mastic round a window
- Weathered mastic on the most exposed windows
Why deal with it now?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a small place like Bethersden, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, 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.

Sand mastic in Bethersden
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. Typical jobs include mastic round period door frames that has failed and weathered mastic on the most exposed windows, across period & listed homes, brick reveals and stone surrounds.
Somewhere as small as Bethersden, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Every job comes with our 12-month guarantee.

Frames and glazing around Bethersden
Historic houses like Godinton House (about 4 miles north-east) are a reminder that the area around Bethersden has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Margaret, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Pluckley station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

What affects the cost of sand mastic
The price is agreed before any work begins. It’s based on:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- Access and height
- The old material and how stubborn it is
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.
What to tell us 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
- The type of property
- Roughly how big the job is
- Any previous sealing or DIY work
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.

Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too in Bethersden and across Kent. We can quote a run of properties together.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
A careful DIYer can reseal a simple joint, 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.
How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a single window, longer for several. Somewhere as small as Bethersden, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- 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
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts

Do you need sand mastic in Bethersden?
Rain on the window surround works into any crack and pushes it out. Exposed elevations normally fail first.
These are the problems we’re asked about most:
- Gaps where the frame meets the masonry
- Modern sealant on a period surround
- Weathered mastic on the most exposed windows
- Old cement repairs round a window that have failed
Managing a site like Bethersden Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- The length of the guarantee
- Is VAT in the price?
- Whether they seal over old material or remove it
- How much experience the applicator has
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Check the mastic when you check the paintwork
- Make sure water runs off the sill
- Avoid patching sand mastic with silicone
- Get any rot dealt with first
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
