FAQs: Gravesend
Can you work on a hospital site such as Herts and Essex Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Gravesend too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
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.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Can you work while the building is occupied?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
Do the joint edges need to be sound before sealing?
The edges have to be sound. If they’re damaged, we will say so before any sealing.
Will you just go over the old 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.
How we handle expansion joint sealing in Gravesend
We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic and we name it in the quote. We work on podiums and floor movement joints, car park decks and ramps and precast concrete panel joints, and the failures we are asked to look at most are chipped joint edges on forklift routes and car park joints leaking onto vehicles below. Looking for mastic applicators who cover Gravesend? We’ve been sealing commercial buildings since 2005.
Around smaller places such as Gravesend, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For work around Gravesend, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- First, the joints are inspected for width, movement and the type of failure.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.

Advice
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Proprietary pre-formed expansion joint systems
- A joint that has to be widened or re-detailed before it can work
- Broken or spalled joint edges, which need repairing before any sealant goes in
If in doubt, ring 01277 525 020 or email us and we’ll say what we think.

What else we do in Gravesend
Aftercare for building managers
To get the most from the new sealant:
- Clear dirt from joint lines during routine cleaning
- Inspect exposed joints once the cold weather has passed
- Keep racking legs and heavy point loads off floor joints
- Raise snow-clearing blades over deck joints where possible
Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. If anything looks wrong, call 01277 525 020 or use the quote form with photographs.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Resealing early limits the damage.
Floors, slabs and movement joints in Gravesend
Two named trading, business or retail sites lie within about 3 miles of Gravesend. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Central London is about 29 miles from Gravesend. The roads out of London are lined with trade parks and distribution sheds.
Sites like Herts and Essex Hospital, 4.6 miles south-east of Gravesend, carry ambulances, deliveries and visitors’ cars over their road and deck joints. For a school such as Albury Church of England Voluntary Aided Primary School, playground and building joints can be done in the holidays.
Gravesend is about 4 miles north-west of Bishop's Stortford, in Hertfordshire. We cover commercial sites throughout Gravesend, whether it’s a single job or part of a planned programme.

Near you in Gravesend
Around Gravesend, our work takes us to commercial buildings near The Catherine Wheel pub, among other places. For rail, the closest station is Bishops Stortford station, about 4.2 miles south-east of the centre. A little further out are Herts and Essex Hospital (4.6 miles south-east) and Bishops Stortford Local History Museum (3.1 miles south-east).
Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Why deal with it now?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. We will flag where edges need repair before sealing. Older rural buildings around Gravesend move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Signs you need expansion joint sealing in Gravesend
Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.
If one of these sounds familiar, it’s time for a closer look:
- Debris jammed in movement joints
- Joints where the bead has lost adhesion
- Damp inside where a wall movement joint has failed
- Car park joints leaking onto vehicles below
On industrial estates such as Hadham Industrial Estate, 1.6 miles south of Gravesend, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
