Sand Mastic in Eastchurch

- Window mastic to renew ahead of painting
- Gaps where the frame meets the masonry
Sand mastic in Eastchurch, done properly
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on brick reveals, stone surrounds and tenement windows, and people most often call us about a silicone bead on a sash window that spoils the look and failed mastic on an exposed elevation.
Around Eastchurch, 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.
Big or small, you get the same 12-month guarantee in Eastchurch and across Kent.

Eastchurch homes and the weather
Eastchurch is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Queenborough station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Eastchurch Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours for a single window, longer for several, depending on the size of the job. In a small place like Eastchurch, access is usually the main thing to plan. 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
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
- Clear the area around the work

Why act early in Eastchurch
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Around Eastchurch, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Why us?
- Anti-fungal silicone where joints get wet
- 12-month guarantee on every job
- Quality sealants from Arbo and Everbuild
- An ARBOMaster approved applicator

Eastchurch: your questions answered
Will you come out to Eastchurch?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Queenborough station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses.
How long does sand mastic take?
Most jobs take a few hours for a single window, longer for several, including the preparation. Your quote will say how long we expect yours to take.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we will talk you through it.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Check the mastic when you check the paintwork
- Ask a joiner to look at soft timber first
- Sort the mastic before the decorators arrive
- Do not paint over the new mastic
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
