Woolbeding Sand Mastic
We cover Woolbeding for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Wind and rain getting in round a sash window
- Crumbling sand mastic round a window
- Mastic worn away on windows facing the weather
Sand mastic in Woolbeding
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. If you are dealing with a silicone bead on a sash window that spoils the look and open joints round the window box, we can help, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Woolbeding is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a single window, longer for several and we leave things clean and tidy. Somewhere like Woolbeding needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Ask the planning authority about consent for listed or conservation-area homes
- Plan mastic work ahead of painting
- Keep sills and gutters clear so water drains away
- Avoid patching sand mastic with silicone
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
How we quote for sand mastic
We do not publish a price list, because jobs vary so much. What we look at:

- The number and length of the joints
- The type of sealant required
- The old material and how stubborn it is
Combining jobs into one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Where the job is, and your postcode
- The type of property
- If someone has resealed it before
- A few pictures by email, if you can
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we will talk you through the work and send you a clear quote.
Leave it or put it right?
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. Where a wall is exposed, as many are in small places like Woolbeding, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

- Sash and case windows

- Stone surrounds
- Brick reveals
What we’re called out for in Woolbeding
Shallow joints are a common cause. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
If you can see any of these, it’s time to have the joints looked at:
- Mastic round period door frames that has failed
- Old sand mastic that has cracked, crumbled or fallen out
- Silicone on a period window that looks wrong
- Cement or filler used on old window joints that has cracked
For an older house near a landmark such as The Parish Church of All Hollows, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions from Woolbeding
Is Woolbeding within the area you cover?
Yes, Woolbeding is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What guarantee comes with sand mastic in Woolbeding?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
How long does sand mastic take to harden?
It takes a while. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
What is sand mastic?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
What information do you need?
Let us know what needs doing and where. We’ll ask anything else we need to know.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Are you insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
DIY sealant or a professional job?
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 jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Woolbeding homes and the weather
Historic houses like Cowdray House (about 1.3 miles south-east) are a reminder that the area around Woolbeding has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
If you look after a building such as Stedham Primary School, the mastic around its windows and doors needs looking after like any other building’s.
