About our expansion joint sealing in Mystole

Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. We work on podiums and floor movement joints, precast concrete panel joints and brickwork movement joints, and what we are called in for most is water dripping through deck or ramp joints and joints packed with grit and debris. Whoever orders the work in Mystole, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

In and around smaller places like Mystole, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Building owners, agents and FMs in Mystole

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Mystole can form part of a wider programme across Kent.

Why deal with it now?

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. Tell us what has to stay open and we will plan around it. For buildings around smaller places like Mystole, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

We don’t publish prices, since every building and every scope is different. Call for a quote.

Why us?

  • Commercial sealant work since 2005
  • Colour options checked against the specified product
  • Standard and matched colours in many product ranges
  • Public liability insurance in place

Common questions from Mystole clients

Is Mystole off your patch?

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

Do you cover business parks and estates near Mystole, such as Stour Valley Business Park?

Yes. Estates, retail parks and business parks around Mystole, Stour Valley Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Can the building stay open while you work?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

What causes movement joint sealant to fail?

The way it has failed usually tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

What sealant do you use in movement joints?

It depends on the movement, exposure and traffic. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints, and the specification has the final say.

Site staff or a sealant specialist?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Rural sites near Mystole may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Send your site hours and access windows
  • Let building users know which areas are affected

Expansion joint sealing around Mystole: what changes locally

At about 50 miles from central London, Mystole is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.

Hospitals like Kent and Canterbury Hospital (3.8 miles east of Mystole) have multi-storey or surface car parks whose joints carry vehicles round the clock. At places like CMA Industrial Park, 1.7 miles north-east of Mystole, joints are sealed a section at a time so operations carry on. In a school such as Chartham Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Mystole is about 4 miles south-west of Canterbury, in Kent. Looking for expansion joint sealing in Mystole? We can help. Mystole is one of 931 places in Kent on our list. Our London page has more on work in that area (50 miles or so).

We cover the CT4 postcode districts for movement joints. Buildings on Thruxted Lane and Mystole Lane are within our area for movement joints. If your building is just outside Mystole, we cover Shalmsford Street (1 mile east), Chartham (1 mile north-east), Garlinge Green (1 mile south-east), Chartham Hatch (2 miles north) and Petham (2 miles south-east). Bigger towns within reach include Ashford (9 miles south-west), Canterbury (4 miles north-east), Dover (15 miles south-east), Sittingbourne (13 miles north-west), Folkestone (13 miles south-east) and Whitstable (7 miles north).

Keeping the joints sound

After handover, a little attention goes a long way:

  • Keep product details with the building records for the next reseal
  • Treat a small split as a warning, not a cosmetic issue
  • Raise snow-clearing blades over deck joints where possible
  • Clear dirt from joint lines during routine cleaning

Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check and long before edges start to break. If anything looks wrong, call the office on 01277 525 020 or email drawings and photos with photos.

Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors, well after the seal first opened. Catching it early keeps the water outside.
