Sealant specialists in Wadhurst

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). The enquiries we see most involve messy, uneven beads from earlier work that let the building down and external beads that have gone brittle and cracked, across kitchen worktops and splashbacks, external facade joints and floor and threshold joints. Searching for sealant specialists in Wadhurst? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

On a typical commercial building in Wadhurst, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Around smaller places such as Wadhurst, small firms often work from converted barns, yards and rural units. Old masonry and timber meet new glazing and partitions in these buildings, and every junction needs a sealant that suits it.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • A failed roof covering or waterproofing membrane
  • Walls or slabs moving more than any sealant can take
  • Suspect materials that need testing and specialist removal

Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Where we work in Wadhurst

How the job changes by surface

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. Old sealant comes out and a sanitary silicone with anti-mould additives goes in.

Shop fronts and retail fit-outs

In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line, often in a colour to suit the brand finish. We will confirm the colours available for the specified product.

FAQs: Wadhurst

Can you supply sealant in our brand colour for a site in Wadhurst?

Yes, we can usually get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.

Is Wadhurst too far out for you?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Can areas stay open during the work?

Phased work can be planned so areas stay in use. Tell us your site hours and access windows and we’ll plan around them.

Could the old sealant in an older building contain asbestos?

In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Do you work directly for building managers?

Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process, with a 12-month guarantee on the workmanship.

Commercial premises in Wadhurst

Wadhurst 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. Wadhurst lies roughly 35 miles out from central London. The commuter belt holds a great many offices, retail parks and business parks. Firms with branches across the South East can use one contractor for every site.

Offices and shops close to stations such as Wadhurst station (to the north-west of Wadhurst) tend to be busy all day, so sealant work is planned around opening hours.

Signs you need commercial sealant contractors in Wadhurst

When a bead peels cleanly off one face, it has failed in adhesion. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.

It’s worth sending us details if you spot any of the following:

  • Window and door perimeter joints that have cracked open
  • Greasy, split joints in a kitchen or tea point
  • Untidy joints in a reception, shop floor or lobby
  • Earlier reseals applied straight onto the failed bead

On estates like Durgates Industrial Estate (less than half a mile north-west of Wadhurst), the office and welfare end of each unit has its own sealant to maintain.

Before you book anyone

  • Their public liability cover
  • Can the work be phased to keep areas open?
  • How the existing material will be dealt with
  • Are they CHAS accredited or on Constructionline?

Choosing a commercial sealant contractor

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a job in Wadhurst, the main thing is a clear picture of the work. A fixed quote follows.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. Completed areas are signed off with you under our 12-month guarantee.
