About our sand mastic in Woodhatch
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We are often asked to deal with mastic dropping out of the joint and window mastic to renew ahead of painting, across brick reveals, sash and case windows and stone surrounds.
Mastic can only go onto a dry, clean joint, so window work in Woodhatch is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You get a one-year guarantee, the same in Woodhatch as everywhere else we work.

When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Planning or listed building consent (your local planning authority decides)
- Masonry that needs repairing
- Cracked or broken glass
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

What else we do in Woodhatch
DIY sealant or a professional job?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Quotes for sand mastic in Woodhatch
We don’t publish a price list. What we look at:
- Access and height
- Working hours on commercial sites
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the property is
- Any access issues, like height or stairs
- Whether it has been sealed before
- The type of property
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Questions from Woodhatch
Do you cover smaller places like Woodhatch?
Yes. Woodhatch is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee on sand mastic in Woodhatch?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
Can you replace silicone on a period window with sand mastic?
Normally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
The process
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a single window, longer for several, depending on how much there is to do. In a small place like Woodhatch, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
How to prepare
- Clear items away from the joints we’re working on
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
