Sand mastic in East Boldre
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. We work on brick reveals, period & listed homes and timber door frames, and the jobs we see most are wind and rain getting in round a sash window and a silicone bead on a sash window that spoils the look.
Somewhere as small as East Boldre, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What sand mastic looks like in East Boldre
East Boldre is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. With historic houses such as Beaulieu Palace House (about 1.3 miles north-east) nearby, there’s older building stock in the area around East Boldre as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Letting a property close to Beaulieu Road station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Beaulieu Village Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Common questions in East Boldre
Will you come out to East Boldre?
Yes. East Boldre is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Beaulieu Road station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.
When will the new mastic be hard?
Not right away. It skins first and hardens fully later and we’ll give you an idea for your job.
Is consent needed for window work on a listed home?
Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you are 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.
What we are called out for in East Boldre
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber, and they generally need raking out.
Look out for any of the following:
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic worn away on windows facing the weather
- Open joints round the window box
- Draughty sash windows at the surround
For an older house near a landmark such as Church of St Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- Whether all the old sealant comes out first
- What the cure time is
- What guarantee comes with the work
What the job involves on each surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. It’s renewed by hand.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid heavy scraping on the mastic joint
- Avoid patching sand mastic with silicone
- Get any rot dealt with first
- Look over the window mastic once a year
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
When it is not the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Sashes that rattle, stick or won’t open
- Broken panes
- Whether work needs listed building consent
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

What we do, step by step
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work starts. Most jobs take a few hours for a single window, longer for several. In a small place like East Boldre, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
