Commercial mastic work in Kippington

A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead. We work on kitchen worktops and splashbacks, external facade joints and floor and threshold joints, and the usual reasons a site gets in touch are black mould through washroom sealant that won’t clean off and a top-up bead over failed sealant, now lifting. For commercial sealant work in Kippington, you deal with one contact from quote to sign-off, whether it’s one building or several.

A lot of what we do in Kippington is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Sealant jobs for businesses in a place the size of Kippington are often best grouped: shopfront, washroom, kitchen and any external joints done together. That keeps travel and disruption down, and where colour matters on the frontage, we will confirm what’s available for the product.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Common problems we fix in Kippington

Resealing over the top is a false economy we come across often. New silicone has nothing to key into. Getting back to a clean joint then means removing every layer.

Most enquiries start with one or more of the following:

  • Frame sealant that has cracked, shrunk or pulled away
  • Black mould through washroom sealant that won’t clean off
  • Shrunken sealant along kitchen worktops and splashbacks
  • Hardened, chalky sealant on south-facing or exposed elevations

For premises near Sevenoaks station (0.5 miles north of Kippington), footfall is part of the plan: work is phased so shops and offices keep trading.

Before you book anyone

  • Can the work be phased to keep areas open?
  • How long is the guarantee, and what does it include?
  • The named product and why it was chosen
  • Do they follow the manufacturer’s priming guidance?

Choosing a commercial sealant contractor

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Cracking that needs a structural engineer to look at it
  • A dripping trap, valve or pipe behind a fitting
  • A failed roof covering or waterproofing membrane

If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think.

Joints and surfaces we work on

  • Washrooms and tea points
  • Floor and threshold joints
  • External facade joints
  • Window and door perimeters
  • Movement joints in walls and floors
  • Kitchen worktops and splashbacks

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a few hours for one area, or a planned series of visits across a bigger building, and our waste is bagged and taken away as we go. If neighbouring businesses or buildings around Kippington need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. First, details reach us through the quote form or a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

What we need from you

  • Explain the parking and delivery arrangements
  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification

Request a quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Kippington: questions and answers

Can you work at a site such as Salters Heath Business Centre, by Kippington?

Yes, sites like Salters Heath Business Centre are within our area, along with the rest of Kippington. Photos and a short description are enough for a first look.

Do hotels near Kippington have to close for sealant work?

Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we’ll plan around them.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

What site paperwork can you provide?

We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.

Will the building have to shut during the work?

That comes down to planning: 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.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Respect the cure time before reopening an area
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Act on the first lifting edges rather than waiting
  • Look at the sealant around anything that has been moved or replaced

Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed. If that happens, phone 01277 525 020 or email us and we’ll price putting it right.

Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. At that point it’s a repair job rather than a reseal.

What the job involves on each surface

Facade and cladding joints

Facade joints move every day as panels warm and cool. The product has to suit the movement, and the depth has to be controlled with backing. Access, such as scaffold already up, is agreed before the price is fixed.

Shop fronts and retail fit-outs

Most shops can’t close for a reseal. We plan around the access windows the store gives us.
