What the job involves on each surface
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen.
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.
Expansion joint sealing for commercial buildings in Shepherd's Green
We’ve been sealing expansion and movement joints for over 20 years, for main contractors, FMs, managing agents and building owners.

We work on car park decks and ramps, cladding panel joints and blockwork control joints, and the usual reasons a site gets in touch are hardened, cracked sealant on exposed facades and spalled or broken joint edges in floors and decks.

Smaller community and commercial buildings around Shepherd's Green have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

After the work
After handover, these steps help:
- Keep traffic off new joints until the cure time is up
- Include every elevation and deck joint in periodic inspections
- Act on the first tear or lifting edge rather than waiting
- Brief car park operatives to protect joint lines during winter clearance
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears. Regular sweeping keeps joint lines clear.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Sealing early protects the edges.
Building owners, agents and FMs in Shepherd's Green
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Common questions from Shepherd's Green clients
Do you cover business parks and estates near Shepherd's Green, such as Vanalloys Business Park?
Yes. Estates, retail parks and business parks around Shepherd's Green, Vanalloys Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is a smaller place like Shepherd's Green outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
How much does the work cost?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.
Why has the sealant in our expansion joints split?
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 seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Shepherd's Green can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Getting the site ready
- Have the specification and drawings to hand
- For older buildings, check the asbestos register before work
- Point out any areas we must not close
Quotes
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

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.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Floors, slabs and movement joints in Shepherd's Green
Shepherd's Green is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in. Shepherd's Green lies roughly 38 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.
Campuses like University of Reading (4.2 miles south-east of Shepherd's Green) mix old and new buildings, with movement joints wherever they meet. Parks like Vanalloys Business Park, 2.1 miles to the west of Shepherd's Green, combine paved areas, car parks and building elevations, each with joints that move. For an estate such as Townlands Memorial Hospital, 2.7 miles to the east of Shepherd's Green, the joints in ramps, decks and long building elevations all need attention over time.

What happens if it’s left?
Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme because damage continues. We can split the scope into urgent and planned. One visit to deal with every failing joint makes more sense than several trips to a place like Shepherd's Green. Send photos of each area and we will quote for the lot.
