How we handle expansion joint sealing in Coleman's Hatch
The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. The enquiries we see most involve hardened, cracked sealant on exposed facades and joints where the bead has lost adhesion, on podiums and floor movement joints, precast concrete panel joints and brickwork movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Coleman's Hatch it comes down to the same thing: the right product in a properly prepared joint.
Halls, schools and small commercial buildings near places like Coleman's Hatch have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Doing it in-house
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Surface by surface
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies before the bead goes in.
On site: what to expect
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Coleman's Hatch are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- 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.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000
- Point out any areas we must not close

What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Changing the joint layout or spacing of a structure
- Concrete or masonry repairs along the arrises
- Waterproofing layers buried beneath the sealant

Expansion joint sealing around Coleman's Hatch: what changes locally
Coleman's Hatch has two named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Coleman's Hatch is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.
For an estate such as Queen Victoria Hospital, which lies north-west of Coleman's Hatch, the joints in ramps, decks and long building elevations all need attention over time. Phasing is what makes joint work possible on busy sites such as Riverview Business Park (1.5 miles north-west of Coleman's Hatch): one bay, aisle or car park row at a time.
Coleman's Hatch is about 4 miles south-east of East Grinstead, in East Sussex. Across the TN7 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 308 places in East Sussex. We also cover Brighton, some 20 miles away.

Just outside Coleman's Hatch, we also work in Upper Hartfield (1 mile north-east), Forest Row (1 mile west), Wych Cross (2 miles south-west), Chelwood Gate (3 miles south-west) and Duddleswell (3 miles south).

Around Coleman's Hatch
Locally, jobs take us to sites close to The Hatch Inn and the streets around them. The nearest railway station is East Grinstead station, roughly 4.6 miles north-west of the centre. Well-known places in the area include Queen Victoria Hospital (4.4 miles north-west) and Bolebroke Castle (2.9 miles north-east). Green spaces nearby include Brickfield Meadow.
Do you need expansion joint sealing in Coleman's Hatch?
Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks.
Typical triggers for a call:
- Torn sealant in brick or block movement joints
- Chipped joint edges on forklift routes
- Sealant peeling off one face of the joint
- Car park joints leaking onto vehicles below
Business parks such as Forest Row Business Park (to the north-west of Coleman's Hatch) have car parks, paved areas and long brick and panel elevations, all with movement joints.

Why it’s worth doing now in Coleman's Hatch
A torn seal left alone usually gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Halls, stores and units around places like Coleman's Hatch may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Common questions from Coleman's Hatch clients
Is a hospital such as Queen Victoria Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is Coleman's Hatch 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 photos up front let us bring everything on the first visit.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
What’s the difference between an expansion joint and a movement joint?
The terms overlap a great deal. A movement joint allows for expansion, contraction, shrinkage and loading, and the seal across it keeps water and debris out.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
What sealant do you use in movement joints?
Movement capability matters most as set out in BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.
