Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
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.
Expansion joint sealing in Lenham Heath, done properly
Width, depth and product all have to work together. 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 and the bead bonds to the sides, never the back. The enquiries we see most involve sealant pulling off the joint face and water getting into the wall through a failed joint, across cladding panel joints, brickwork movement joints and podiums and floor movement joints. One point of contact handles commercial sealant work in Lenham Heath from the first photos to the final walk-round, for single jobs and planned programmes alike.
Jobs around smaller places like Lenham Heath are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we’ll take it from there.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Doing it in-house
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
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.
Slabs, ramps and loading bays in Lenham Heath
The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints. Lenham Heath lies roughly 41 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.
Schools such as The Lenham School have movement joints in their walls and floors that are easy to overlook.

Surface by surface
Cladding panel joints
We confirm what access is in place before pricing. Photos taken near the joints help us price accurately.
Car park decks and ramps
Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed flagging broken edges along the way.
Common problems we fix in Lenham Heath
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.
Site and facilities staff are often the first to spot these:
- Debris jammed in movement joints
- Hardened, cracked sealant on exposed facades
- New sealant over old, now failing
- Rain penetration at brick or block movement joints
Campuses like Canterbury Christ Church University (to the north-west of Lenham Heath) mix old and new buildings, with movement joints wherever they meet.
Questions to ask before you book
- Whether their applicators hold CSCS cards
- The terms of the workmanship guarantee
- Which product they’ll use, and why it suits the joint
- How they handle RAMS and site documents
On site: what to expect
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Smaller jobs around Lenham Heath can be grouped with others nearby. A fixed quote is given before anything starts.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
- Agree which areas must stay open

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Common questions from Lenham Heath clients
Does a site in Lenham Heath have to shut while its joints are sealed?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.
Which documents can you supply for work in Lenham Heath?
RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
What’s the difference between an expansion joint and a movement joint?
They’re closely related. A movement joint allows for expansion, contraction, shrinkage and loading, and the seal across it keeps water and debris out.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Why do our movement joints keep failing?
Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. We diagnose which one it is before resealing since each needs a different fix.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Why deal with it now?
Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now, as damage continues meanwhile. Urgent joints now, the rest later, is often the sensible plan. For buildings around smaller places like Lenham Heath, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
