About our expansion joint sealing in Greenhill
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on cladding panel joints, podiums and floor movement joints and precast concrete panel joints, and the usual reasons a site gets in touch are brittle, chalky sealant on external joints and water dripping through deck or ramp joints. Whoever orders the work in Greenhill, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Rural business units around smaller places such as Greenhill 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.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Maintenance after handover
After handover, these steps help:
- Note which joints were done, when, and with what
- Raise snow-clearing blades over deck joints where possible
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Leave barriers in place until fresh joint sealant has cured
Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint and we’ll tell you when each bay or area can reopen. Barriers left in place until then protect the finish.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Sealing early protects the edges.
Common problems we fix in Greenhill
Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. The product has to be suited to the traffic.
It’s worth sending us details if you spot any of the following:
- Layers of sealant in a movement joint
- Joints where the bead has lost adhesion
- Water dripping through deck or ramp joints
- Expansion joints split through the centre of the bead
A campus such as University of Kent, 4.8 miles to the south of Greenhill, has long runs of movement joint in its buildings, decks and paving.
Questions to ask before you book
- Is the sealant right for the movement and the substrate?
- How the joint faces will be prepared and primed
- Proof of insurance
- How long is the guarantee, and what does it include?
Doing it in-house
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What happens if it’s left?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we will tell you they need repairing first. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Greenhill: questions and answers
Can you take on a job at a hospital such as Queen Victoria Memorial Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Does the sea air around Greenhill change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.
Can you work while the building is occupied?
Normally, yes. Phased work can be planned so areas stay in use.
Do you reseal car park expansion joints?
Yes. Tell us how the car park is used and which areas must stay open.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Can you seal joints in cold or wet weather?
Sealing onto a damp surface leads to adhesion failure so we’d rather rearrange than seal in the rain. The work is simply moved to the next suitable day.
Can a joint be sealed if the edges are broken?
The edges have to be sound. If they’re damaged, we will say so before any sealing.

Cost factors for movement joints
The price varies from site to site. It mainly depends on:
- The site’s rules and procedures
- Specialist products, such as fire-rated or hygienic sealants
- Working within restricted access windows
- Backing rod, priming and other preparation
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- Any specification or named product
- Photos of the joints, close up and from further back
- The type of building and who uses it
- Access details, including height
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Floors, slabs and movement joints in Greenhill
Greenhill sits close to the coast, within about 1 mile. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, which is why split joints are worth sealing before the edges deteriorate. The South East is one of the drier 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.
Phasing is what makes joint work possible on busy sites such as St. Augustine's Business Park (1.2 miles west of Greenhill): one bay, aisle or car park row at a time. Business parks such as Eddington Business Park, 0.8 miles east of Greenhill, have car parks, paved areas and long brick and panel elevations, all with movement joints.

Diagnose, treat, sign off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. If neighbouring businesses or buildings around Greenhill need work too, visits can be combined. Tell us your site hours and we will plan around them.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- 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.
