Sand mastic in Nettlestone
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap and tidies the surround. If you’re dealing with draughty sash windows at the surround and failed mastic on an exposed elevation, we can help.
Outdoor sealant needs dry, clean surfaces, so work on frames around Nettlestone is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee, whatever its size.

When to call us in Nettlestone
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
Look out for any of the following:
- Failed mastic on an exposed elevation
- Modern sealant on a period surround
- Crumbling sand mastic round a window
- Cement or filler used on old window joints that has cracked
For landlords with property near Smallbrook Junction station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a single window, longer for several. Somewhere like Nettlestone needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can

Frames and glazing around Nettlestone
Nettlestone is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Nunwell House (about 2.8 miles south-west) are a reminder that the area around Nettlestone 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.
Schools such as Nettlestone Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as St. Helen's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How long does sand mastic take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we will say how long yours will take.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
How we quote for sand mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- The type of sealant required
- The size of the job
- When we can work, for business premises
- How easy the joints are to reach
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
What we need to know
Photos by email are helpful but not essential. Please mention:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- The problem you’ve noticed
- How many joints, rooms or windows are involved
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, ring 0345 464 0079 or email us.
Keeping the joints in good condition
Aftercare is simple:
- Don’t paint over the new mastic
- Go gently near the mastic when preparing windows
- Ask a joiner to look at soft timber first
- Inspect the joints round the windows every year or so
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
