When to call us in Havant
Outside, sunlight and rain wear sealant down year after year. UV hardens the surface while wind and rain work at the edges, so beads chalk, stiffen and lose their stretch. A hardened bead can’t follow the building any more.
Look out for the following:
- Black mould through washroom sealant that won’t clean off
- Gaps behind commercial kitchen worktops and sinks
- Expansion joints with the sealant torn out
- External beads that have gone brittle and cracked
Premises within reach of Havant station (to the south of Havant) often have busy frontages where joints are seen by everyone passing.

Commercial sealant contractors for commercial buildings in Havant
Failed sealant isn’t always the whole story. A leak near a frame edge can start in the frame, the cill or the cavity. We look before we quote and tell you plainly if sealant won’t solve it, so nobody pays for a reseal that can’t hold. If you are dealing with water staining near frames, panels or ceilings and a top-up bead over failed sealant, now lifting, we can put it right. A specialist sealant contractor works differently from a general builder: in Havant, that means joint design, primers and backing rod as standard.
Quotes for commercial sealant in Havant can come from photos and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.
For a business or landlord in Havant with one or two premises, it makes sense to bundle sealant jobs together: say a shopfront perimeter, a tea point, a washroom and some frames. A single fixed quote covers everything on the list.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What the job involves on each surface
Commercial kitchens and tea points
Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. They’re degreased thoroughly before resealing, and a hygienic or food-safe sealant is used where food contact is possible.
Window and door perimeters
The perimeter joint between a frame and the structure keeps rain out of the reveal. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.
Working on commercial sites near Havant
Havant sits close to the coast, within about 2 miles. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. Where a frontage needs a particular colour, the product still has to suit that exposure. The area within 2 miles of Havant holds several hotels. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes; work is planned so the hotel keeps trading.
Retail sites such as Central Retail Park, 0.7 miles south of Havant, are typical of where shop-fit joints, frontages and staff areas need neat, colour-matched sealant. For a hotel such as The Bear Hotel, which lies south of Havant, the colour of a joint at the bar or the bath matters to the look of the room.

Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Note dates and locations of sealant work for future planning
- Make sure contractors see the asbestos survey before cutting out old mastic
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Report cracked or peeling sealant early
In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, which is how mould gets back in. It’s worth having fans checked while the sealant is fresh.
Sealant rarely fails all at once across a building. A few splits this year normally mean more next year so the whole run is worth inspecting. We can assess the lot and suggest what to do now and later.

Advice
Work for main contractors and building owners
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

What happens if it’s left?
Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. In a town such as Havant, a lot of buildings are older and have been altered over time, so joints between old and new are often the first to go. Resealing them early protects the building behind.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Questions about Havant
Can being near the sea in Havant affect the sealant we need?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Does your area include sites such as Central Retail Park, near Havant?
Yes, sites like Central Retail Park are within our area, along with the rest of Havant. A few photos and the unit address let us price the work.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
What guarantee do you give on resealing?
Our workmanship is guaranteed for 12 months. Public liability insurance is in place too.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
Do you work for facilities managers and managing agents?
Yes. A large share of our work comes through facilities managers, managing agents and landlords, alongside main contractors. Tell us how you issue work and we’ll fit in.
