Sealant on show in Kencot’s commercial buildings
Kencot sits in one of the drier corners of the country, the South East. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. Less than 3 miles from Kencot there are at least three named estates and business parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen.
If you have premises on more than one site, say at Carterton South Industrial Estate and West Oxon. Industrial Park, one contractor and one quote can cover both.
Kencot is about 2 miles south-west of Carterton, in Oxfordshire.

Commercial mastic work in Kencot
We’ve applied sealant on commercial sites for over 20 years, and the paperwork side is in order: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. The enquiries we see most involve messy, uneven beads from earlier work that let the building down and mouldy silicone around WCs, urinals and vanity tops, on movement joints in walls and floors, external facade joints and washrooms and tea points. Looking for mastic applicators who cover Kencot? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Occupied buildings in Kencot need the work phased: we agree the order with you and hand back each area with its cure time.
Business units in the countryside around places like Kencot 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.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Maintenance after handover
For the best life from the joints:
- Keep washroom and kitchen extraction working
- On pre-2000 buildings, share the asbestos information before work starts
- Keep abrasive pads and scrapers off resealed joints
- Note dates and locations of sealant work for future planning
New joints need their full cure time before they take water, cleaning or traffic. That time depends on the product, the temperature and the joint depth, and we confirm it when each area is handed back. Keeping signs or barriers up until then protects the finish.
Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.
When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

On site: what to expect
Inspect, seal, sign off: every visit follows that pattern. 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. For work around Kencot, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- You send photographs, drawings or a list of the joints and areas involved, or we arrange a site visit.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Before anything is cut out, we agree access, timings and sequence.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- We walk the completed areas with you and sign them off under the 12-month guarantee.

Signs you need commercial sealant contractors in Kencot
The wrong sealant in the wrong place is a common cause of early failure. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason.
It’s worth sending us details if you spot any of the following:
- Damp patches where an external joint has failed
- Mouldy silicone around WCs, urinals and vanity tops
- Hardened, chalky sealant on south-facing or exposed elevations
- Frame mastic that has hardened and come away from the wall
Industrial estates such as Carterton South Industrial Estate, 1 mile north-east of Kencot, have offices, trade counters and welfare areas whose sealant ages like any other building’s.
Before you book anyone
- Are they CHAS accredited or on Constructionline?
- How they’ll work around occupants
- How the joint faces will be prepared and primed
- Will RAMS and insurance details be available?
What happens if it’s left?
It can be tempting to hold sealant work back until the next refurbishment. That’s reasonable for internal joints that are just tired-looking, but external and wet-area joints that already leak shouldn’t wait. Splitting the scope into now and later is often the sensible compromise. Around Kencot, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

FAQs: Kencot
Is Carterton South Industrial Estate, near Kencot, within your area?
Yes. We cover Kencot and the area around it, including industrial estates, business parks and retail parks such as Carterton South Industrial Estate. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Do you offer colour-matched sealant for buildings in Kencot?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.
How do you keep disruption to occupiers down?
It’s mostly about sequence: areas are phased, access windows agreed and enough washrooms or entrances left in use. Let us know what can’t close and we’ll work around it.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Is failed sealant stripped out, or sealed over?
Removal of the failed sealant is always part of the job. New sealant can’t grip the old bead, so laying over it never lasts; the faces are then cleaned and prepared.
Are you CHAS accredited?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
How long does a typical visit take?
It depends on the scope, but the work usually takes part of a day on a small job and longer where several buildings or phases are involved. Larger or phased jobs take longer, and we will give you a timescale with the quote.
