About our mastic sealing in Balmerlawn
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. If you’re dealing with cracked, hardened mastic round windows on a block and mastic failing across several blocks on an estate, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Balmerlawn is the same: the right product in a properly prepared joint.
Rural conversions near places like Balmerlawn often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Work we carry out in Hampshire comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or send photos by email and we will come back to it.

What else we do in Balmerlawn
Blocks and managed buildings in Balmerlawn
The South East is one of the drier parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.
Site managers at schools like Brockenhurst Church of England Primary School can fit frame mastic into the summer works. Older community buildings, Church of St Nicholas among them, often have frames of mixed ages whose mastic varies.

Leave it or put it right?
Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. For buildings around smaller places like Balmerlawn, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Questions we’re asked in Balmerlawn
Can one quote cover a number of our buildings near Balmerlawn?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
Is Balmerlawn too far out for you?
Not at all. Balmerlawn is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When to call us in Balmerlawn
Occasionally the substrate fails, not the sealant for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
It’s worth sending us details if you spot any of the following:
- A mix of products and colours from past repairs
- Cracked, hardened mastic round windows on a block
- Occupiers reporting cold air round windows
- Failed external movement joints
With historic buildings such as Beaulieu Palace House, 4.9 miles to the east of Balmerlawn, in the wider area, owners of older properties around Balmerlawn should expect mastic to need a product that suits old masonry.

Related advice
Looking after the joints
A few simple habits keep the new joints working:
- Protect low-level joints in entrances
- Avoid piecemeal callouts where you can
- Track which buildings were done and when
- Have the asbestos survey to hand for older buildings
If paintable sealant was used, decoration can follow once it has cured. Silicone usually can’t be painted, so keep decorators off it.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
What the job involves on each surface
Estate-wide resealing programmes
Using the same products throughout keeps the estate consistent and easier to manage.
External movement joints
Joint size and product are matched to the expected movement, often around 2:1 width to depth, as the manufacturer advises.
