Expansion joint sealing in Chatham, done properly
The seal is what lets a movement joint do its job. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on car park decks and ramps, precast concrete panel joints and brickwork movement joints, and the usual reasons a site gets in touch are water getting into the wall through a failed joint and weathered movement joint sealant that no longer flexes. Searching for sealant specialists in Chatham? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Movement joints in a large town like Chatham range from car park ramps and retail floors to the brick and panel joints on bigger buildings. When they fail, water and grit get in, edges break up and leaks follow.
Our workmanship is guaranteed for 12 months, in Chatham as everywhere else we work. If our installation lets you down in that time, we return and fix it.
Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Keep product details with the building records for the next reseal
- Treat a small split as a warning, not a cosmetic issue
- Plan racking layouts so feet don’t land on a joint
- Brief car park operatives to protect joint lines during winter clearance
Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers. Keeping the filler or sealant sound protects the floor.
Diagnose, treat, sign off
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Town-centre jobs in Chatham can mean limited parking and loading, whereas edge-of-town units normally have yard space. Either way, tell us what’s available.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Getting the site ready
- Tell us which areas need to stay in use
- Let building users know which areas are affected
- Clear stock, furniture or equipment away from the joints

Advice
What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Concrete or masonry repairs along the arrises
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Leaks coming from the membrane rather than the joint seal
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

What else we do in Chatham
Questions about Chatham
Must our site in Chatham stop work while the joints are done?
Normally not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we will plan from there.
Do you take on work at healthcare sites like Medway Maritime Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
What do you charge?
There isn’t a price list, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use.
Which product is best for expansion joints?
We choose a sealant with a movement capability that suits the joint as set out in BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.
What the job involves on each surface
Joints between different materials
Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement.
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.
Why deal with it now?
Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s usually not far behind, and a second visit means paying for access again. Where it helps, we quote both options. If one joint has failed on your building in Chatham, others of the same age may be close behind. Renewing them in one programme saves time later.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
