Mastic packages on Havant sites
Havant lies within about 2 miles of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. Several hotels sit less than 2 miles from Havant. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
Hotels like The Bear Hotel, 0.9 miles to the south of Havant, rarely close for long, so refurbishment mastic is phased floor by floor. Recladding or extending a unit at a site like Central Retail Park, 0.7 miles to the south of Havant, brings panel joints and frame perimeters into the programme. Extensions at sites like Elmleigh Hospital, 0.6 miles to the south-east of Havant, typically sit beside working departments, and the mastic follows strict access rules.
Havant is about 18 miles east of Southampton, in Hampshire. We cover Havant and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else. Across Hampshire, 723 places are covered, Havant among them.
Anyone looking for construction mastic in PO9, PO11 and PO7 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. For a building on Colemore Square, Market Parade and Juniper Square or nearby, we can quote for mastic packages. Access to Havant is via the A27 and A3(M), so getting applicators and materials to site is simple. If your building is just outside Havant, we cover Leigh Park (1 mile north), Denvilles (1 mile south-east), Durrants (2 miles north-east), Langstone (2 miles south) and Warblington (2 miles south-east). Further afield, our area takes in Gosport (8 miles south-west), Fareham (9 miles west), Horndean (3 miles north), Hedge End (14 miles west), Petersfield (10 miles north) and Locks Heath (12 miles west). Havant ranks among the main centres of Hampshire, with offices, shops, schools and other public and commercial buildings.

How we handle construction mastic in Havant
Mastic follows everyone else, which means it absorbs every delay upstream. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. Sealing too early only means coming back once others have damaged it. If you have sanitary sealant damaged by following trades and inconsistent sealant finishes from plot to plot, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Havant, that means joint design, primers and backing rod as standard.
Construction in a town such as Havant is often smaller schemes: a few new flats, a school extension, a refurbished unit. The perimeter and facade joints on a small scheme need the same sizing and preparation as on a big one.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Leave it or put it right?
Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area usually clears more for less disruption. We can run snagging as its own phase before handover. In Havant, as anywhere, the simplest time to fix a failed joint is before it leaks. After a leak, there’s drying, repairs and redecoration on top.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

For managing agents and facilities managers
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Havant can sit alongside others in a wider programme.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Rework caused by others damaging completed areas
- Specifying the product where the designer hasn’t
If you are not sure, just phone 01277 525 020 or email us and we’ll give you a straight answer.
Surfaces we seal
- Internal decorators’ caulk
- Floor and skirting junctions
- Cladding and panel joints
- Sanitary and kitchen joints
- Window and door perimeters
- Brick and block movement joints
Doing it in-house
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Our process
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Town-centre premises in Havant may have limited parking, so tell us what’s nearby. On estates and business parks it’s normally simpler.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
Before we start on site
- Share the asbestos register for older buildings
- Have the specification and drawings to hand
- Agree which areas must stay open
Request a quote
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or send photos by email to discuss it first.

Common questions from Havant clients
Can you work on a hospital site such as Elmleigh Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does your area include sites such as Central Retail Park, near Havant?
Yes. Our area takes in Havant and its surroundings, with estates and business parks such as Central Retail Park included. Send details of the unit and the work through our quote form for a quick quote.
What will the job cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote.
Can you clear a mastic snag list before handover?
Yes. Snag-only work is something we take on, cutting out damaged or poor joints and resealing them.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
What happens if the weather stops external sealing?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Sealing in poor conditions risks adhesion failure so it’s better to wait.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
