Sealant specialists in Teynham

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. We work on external facade joints, floor and threshold joints and movement joints in walls and floors, and the failures we’re asked to look at most are gaps behind commercial kitchen worktops and sinks and a top-up bead over failed sealant, now lifting. Most enquiries from Teynham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Occupied buildings in Teynham need the work phased: washrooms in turn, floors in sections and entrances kept open.

Small businesses near places like Teynham frequently occupy converted farm buildings. Those conversions put new frames and partitions against old brick, stone or timber, so each joint needs a product chosen for both surfaces.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When something else is needed

Honesty saves time and money. Fresh joints won’t solve:

  • Walls or slabs moving more than any sealant can take
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Water from a services leak rather than a joint

If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Where we work in Teynham

When to call us in Teynham

Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. In commercial buildings those factors tend to act together, which is why regular inspection pays.

Common reasons buildings call us in:

  • Layers of sealant, all of them failing
  • Leaks that seem to come through a sealant line
  • Smeared sealant across finishes from a rushed job
  • Frame sealant that has cracked, shrunk or pulled away

A hotel such as Hempstead House Hotel (to the west of Teynham) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Before you book anyone

  • How the joint faces will be prepared and primed
  • Are they CHAS accredited or on Constructionline?
  • How long is the guarantee, and what does it include?
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. What matters most for a job in Teynham is a clear list of what needs doing, so send photos of each area. You’ll then get a fixed price for the work.

  1. First, details come to us: photos, drawings or a schedule of the areas, and a site visit is booked where it helps.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. We strip the failed bead and prepare both faces of the joint.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Move anything stored against the joints
  • Arrange parking or a loading space

Commercial clients in Teynham

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

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.

Different surfaces, different methods

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. The design and sign-off of fire stopping belong to the designer and building control.

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. They need a sealant with the right movement capability, laid at the right depth. We confirm the access in place before we quote.

FAQs: Teynham

Do you offer colour-matched sealant for buildings in Teynham?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.

Is Teynham off your patch?

Not at all. Teynham is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do you check for asbestos before removing sealant?

We check the asbestos register or survey before any old sealant is disturbed. Managing asbestos is the dutyholder’s responsibility.
