Hunston Commercial Sealant
Sealant work for offices, hotels, washrooms and commercial buildings for homes and businesses in Hunston and across West Sussex. Fully insured, ARBOMaster approved and guaranteed for a year.
- Split sealant where wet room floors meet walls
- Too many rooms to reseal without closing the building
- Repeated reseals that do not last
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Commercial sealant in Hunston
In student and care accommodation, there are often many near-identical bathrooms. We agree a programme and work through them in order, working around residents and staff routines. We’re often asked to deal with failed joints in office kitchens and tea points and rental bathrooms that need resealing between tenants, across welfare facilities, rental portfolios and student & care accommodation.
For a small place like Hunston, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.
Our work is backed for twelve months, in Hunston and everywhere else we cover.

The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes anything from a few hours to several days, depending on the number of rooms. In a small place like Hunston, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We walk the site with you and agree the rooms, the order and the hours.
- Each area is protected and the old sealant cut out completely.
- We clean the joints, treat any mould and let them dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Rooms are checked and returned with a cure time so staff know when to use them.
Before we arrive
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises

Advice
For landlords and businesses
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
When to call us in Hunston
In office kitchens and tea points, joints are wet and wiped all day, and grease and cleaning sprays break down sealant. The worktop and sink edges normally fail first.
Most people get in touch after spotting something like this:
- Worktop sealant that has shrunk and stained
- Black, stained silicone in guest bathrooms
- Failed floor-level joints in accessible wet rooms
- Sealant failing again soon after quick repairs
Managing a site like North Mundham Primary School? Then sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

What affects the quote in Hunston
Your quote is based on your job. We look at:
- The number of rooms or windows
- The type of sealant required
- The old material and how stubborn it is
- Any working-time requirements on site
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
When you call or email, it’s useful to know:
- A few photos by email, if you can
- Whether it’s a home or a business
- Where the job is, and your postcode
- Roughly how big the job is
We do not publish a price list, because every job is different. Instead, we give you a clear quote for your job. To get started, call 0345 464 0079 or send us an email.
When it is not the sealant
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Certifying fire stopping or building compliance
- A shower tray, bath or basin that’s cracked or broken
- Faulty shower valves and leaking traps
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

Commercial sealant around Hunston
If you run a hotel, guest house or holiday let in a coastal place like Hunston, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Chichester station, several rental properties can be resealed on one programme. Community buildings like St Leodegar's Church are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.

Why act early in Hunston
Room by room, the work is quick: it takes a few hours per room, so whole buildings are phased. After that, each area needs its cure time before use, so planning the order matters more than the hours on site. In a small place like Hunston, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
