What happens if it’s left?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility and a consistent finish. Halls, stores and units around places like Clanfield may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
A quote for mastic packages depends on how many there are, their condition and the access. Call for a quote.

How we handle construction mastic in Clanfield
On a new build, the mastic package is one of the last trades through each area, so it lands at exactly the point the programme is tightest. We work as a mastic subcontractor to main contractors and developers, following the trades through the building as rooms and elevations become ready. If you’re dealing with old sealant on a refurbishment that needs stripping before new work and external joints sealed in damp or cold conditions that are now failing, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Clanfield, that means joint design, primers and backing rod as standard.
Construction in and around smaller places such as Clanfield is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
A 12-month guarantee applies to all our work in Hampshire. Should something we installed fail, call the office on 01277 525 020 or email us and we will come back to it.

What else we do in Clanfield
Do you need construction mastic in Clanfield?
A new building moves while it dries and settles. Materials lose construction moisture and shrink. Picking a flexible sealant where there’s movement keeps snags down.
These are often picked up first by site or facilities staff:
- Early adhesion failures on new external joints
- Frame gaps too wide for sealant alone
- Frame perimeters left unsealed or poorly sealed
- Internal caulk splitting as the building dries out
On a healthcare site such as Petersfield Community Hospital, 5.1 miles to the north-east of Clanfield, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Construction mastic around Clanfield: what changes locally
Clanfield sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Clanfield lies roughly 55 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
School extensions, at buildings such as Clanfield Junior School, normally run to the summer holidays, mastic included. Units on estates such as Enterprise Industrial Estate, 1.8 miles to the south of Clanfield, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Your questions answered
Is Enterprise Industrial Estate, near Clanfield, within your area?
Yes. Our area takes in Clanfield and its surroundings, with estates and business parks such as Enterprise Industrial Estate included. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.
Is Clanfield too far out for you?
Not at all. Clanfield is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Yes, we can. Share the list and photos, and a fixed quote follows, then clear it to your programme.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
What guarantee comes with a mastic package?
It carries a 12-month guarantee on our workmanship. We’re also fully insured for public liability.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
