Sand mastic in Curbridge
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on timber door frames, brick reveals and tenement windows, and people most often call us about failed mastic on an exposed elevation and gaps where the frame meets the masonry.
Mastic can only go onto a dry, clean joint, so window work in Curbridge is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job.

When to call us in Curbridge
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber, and they generally need raking out.
Common reasons people contact us are:
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
- Mastic that needs renewing before redecorating
- Failed mastic on an exposed elevation
In the older streets around Church of St John the Baptist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- Whether the sealant suits the joint
- What insurance they hold
- What happens if the job turns out different
- How long the guarantee is
Honest limits
We will not take on work that will not last, so these are the limits:

- Broken panes
- Rotten sashes, sills or window boxes (a joiner’s job)

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Sand mastic in Curbridge: local notes
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. With historic houses such as Minster Lovell Hall (about 1.8 miles north) nearby, there’s older building stock in the area around Curbridge as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Our Lady of Lourdes Catholic Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Looking after it afterwards
Looking after new joints is easy:
- Clear gutters so water doesn’t pour onto the windows
- Keep modern sealant off the mastic
- Inspect the joints round the windows every year or so
- Check with your local planning authority if your home is listed
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
Quotes for sand mastic in Curbridge
Every job gets its own quote. These are the things that affect it:
- Working hours on commercial sites
- The old material and how stubborn it is
- How much there is to do
- Which sealant suits the joint
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- How many joints, rooms or windows are involved
- If someone has resealed it before
- Where the property is
- Whether it’s a home or a business
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, call 0345 464 0079 or drop us an email.
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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a single window, longer for several. Somewhere as small as Curbridge, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work

I rent my home. Can I book you?

Can you replace silicone on a period window with sand mastic?
In most cases. We remove the silicone and clean the joint before the sand mastic goes in.
Can you seal over the old sealant?

Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
