Bursledon Sand Mastic
Sand mastic in Bursledon from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Crumbling sand mastic round a window
- Gaps round a timber door in stone or brick
- Wind and rain getting in round a sash window
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Look over the window mastic once a year
- Sort the mastic before the decorators arrive
- Make sure water runs off the sill
- Avoid patching sand mastic with silicone
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
Sand mastic for homes and businesses in Bursledon
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on tenement windows, period & listed homes and sash and case windows, and people most often call us about mastic round period door frames that has failed and a silicone bead on a sash window that spoils the look.
Houses in smaller places like Bursledon can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

What we’re called out for in Bursledon
Shallow joints are a common cause. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
Any of these means the joints need attention:
- Patchy fillers round a sash window
- Mastic that needs renewing before redecorating
- Mastic dropping out of the joint
- Gaps where the frame meets the masonry
For site and facilities teams at buildings such as Bursledon Church of England Infant School, the mastic around its windows and doors needs looking after like any other building’s.
Before booking anyone
- Is the old sealant removed completely?
- Is VAT in the price?
- Who turns up on the day
- How long the guarantee is
What happens on the day
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a single window, longer for several. For a job in Bursledon, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Move anything stored near the joints
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Questions from Bursledon
Can you help a landlord with a rental near Bursledon station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
Does living near the coast affect sand mastic in Bursledon?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
When will the new mastic be hard?
It skins over fairly quickly but takes longer to harden fully. We will explain what to expect before we leave.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Why it’s worth doing now in Bursledon
Filling over old, loose mastic does not last. We remove the loose material first so the new mastic stays put. Around Bursledon, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
What you get with us
- A 12-month guarantee on all work
- Old sealant always removed completely
- Sanitary silicone with an anti-fungal additive in wet areas
- 180+ five-star Google reviews

What sealant work can’t fix
In fairness, there are a few things sealant won’t fix:
- Damaged stone surrounds
- Sashes that rattle, stick or will not open
- Planning or listed building consent (your local planning authority decides)
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

What the job involves on each surface
Period and listed homes
Materials matter on listed and conservation-area homes. Like-for-like sand mastic is generally favoured.
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Frames and glazing around Bursledon
Bursledon is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St Paul’s Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Bursledon station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
