Expansion joint sealing near Kemsley

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Expansion joint sealing for commercial buildings in Kemsley

For movement joints in Kemsley, photos and approximate lengths are the best start. We’ll come and look where photographs don’t show enough, then send a fixed quote that names the sealant. To discuss the joints first, give us a call on 01277 525 020 or use the quote form. If you are dealing with sealant peeling off one face of the joint and previous reseals laid over old sealant, we can put it right, on cladding panel joints, blockwork control joints and podiums and floor movement joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Kemsley is the same: the right product in a properly prepared joint.

Rural business units around smaller places such as Kemsley often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or email the details over and we will come back to it.

Different surfaces, different methods

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies, then seal and tool the joint.

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.

Building owners, agents and FMs in Kemsley

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Expansion joint sealing around Kemsley: how the place shapes the job

The sea is no more than about 1 mile from Kemsley. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster. Rainfall across the South East, Kemsley included, is lower than in many parts of the UK. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.

Office parks like Newington Enterprise Centre (to the west of Kemsley) have decks, ramps and clad elevations whose joints take movement every day. In a school such as Kemsley Primary Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Kemsley is about 1 mile north of Sittingbourne, in Kent. Commercial clients in Kemsley use us for work on movement joints, as part of our coverage of Kent. We work across 931 places in Kent. Sites around London have their own page, roughly 37 miles from Kemsley.

Questions about Kemsley

Can being near the sea in Kemsley affect the sealant we need?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Do you take on work at healthcare sites like Sittingbourne Memorial Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

Do your applicators hold CSCS cards?

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

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

What timescale should we allow for resealing expansion joints?

It typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. We’ll confirm when each area can be used again.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

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.

Do you need expansion joint sealing in Kemsley?

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears, which is why depth control matters.

These are often picked up first by site or facilities staff:

  • Sealant peeling off one face of the joint
  • Expansion joints filled with dirt and stones
  • Torn sealant in brick or block movement joints
  • Rain penetration at brick or block movement joints

For an estate such as Sittingbourne Memorial Hospital, 1.8 miles south of Kemsley, the joints in ramps, decks and long building elevations all need attention over time.

Choosing a commercial sealant contractor

Why it’s worth doing now in Kemsley

Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use without shutting the whole car park. We agree phasing with you before work starts. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Our process

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If neighbouring businesses or buildings around Kemsley need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Before we start on site

  • Make sure the joints can be reached
  • Agree which areas must stay open
  • Let building users know which areas are affected
