- Broken glass or blown double-glazed units

The most common commercial job in Hensting is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.
Business units in the countryside around places like Hensting are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

FAQs: Hensting
Will you take on work at estates like Wessex Business Park, close to Hensting?
Yes. We cover Hensting and the area around it, including industrial estates, business parks and retail parks such as Wessex Business Park. Photos and a short description are enough for a first look.
Can you supply sealant in our brand colour for a site in Hensting?
Yes, we can typically get close to most finishes from the product’s colour range. Send colour references or photographs and we will confirm what’s available for the product.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Is your work guaranteed?
Our workmanship on each job is backed by a 12-month guarantee. Public liability insurance is in place too.
What we’re called out for in Hensting
If only one face has lost its grip, that’s an adhesion failure. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. It’s one of the commonest faults we find on earlier work.
Site and facilities staff are often the first to spot these:
- A top-up bead over failed sealant, now lifting
- Smeared sealant across finishes from a rushed job
- Leaks that seem to come through a sealant line
- Hardened, chalky sealant on south-facing or exposed elevations
Sites a few miles apart, such as Wessex Business Park and Vicarage Farm Business Park, can share one programme and one point of contact.
What to look for in a quote
- Their public liability cover
- How they’ll work around occupants
- Will RAMS and insurance details be available?
- Do they follow the manufacturer’s priming guidance?
Cost factors for sealant joints
Quotes vary with the job. Expect it to depend on:
- Specialist products, such as fire-rated or hygienic sealants
- Site requirements such as inductions and permits
- Whether old sealant has to be cut out first
- The total length or number of joints
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- The product your specification calls for
- The asbestos register, for older buildings
- The type of building and who uses it
- Clear photos of the problem areas
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Commercial sealant contractors in Hensting: the local picture
Hensting is in the South East, one of the UK’s drier regions. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Hensting lies roughly 62 miles out from central London. The commuter belt holds a great many offices, retail parks and business parks. Multi-site occupiers here often want one sealant contractor across all their buildings.
Shops and cafés around stations like Shawford station (to the north-west of Hensting) trade from early, so work is timed around them. A hotel such as Marwell Hotel, 0.7 miles to the south of Hensting, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

How the job changes by surface
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.
Shop fronts and retail fit-outs
Retail work typically has to fit around trading. Tell us your trading hours and access windows and we will plan around them, phasing areas so the shop floor stays usable.
Building owners, agents and FMs in Hensting
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes part of a day on a small job and longer where several buildings or phases are involved, and we clear our waste as we work. If others near Hensting need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- First, details reach us through the quote form or a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
