How we handle expansion joint sealing in Rainham
Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied. The enquiries we see most involve new sealant over old, now failing and arrises breaking up along floor joints, on cladding panel joints, precast concrete panel joints and podiums and floor movement joints. Most enquiries from Rainham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Joints in town car parks and service yards take tyres, de-icing salt and standing water. Resealing before the edges break up is far less disruptive than repairing them later.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Rainham: questions and answers
Will you take on work at estates like Parkwood Shopping Centre, close to Rainham?
Yes. We cover Rainham and the area around it, including industrial estates, business parks and retail parks such as Parkwood Shopping Centre. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Can being near the sea in Rainham affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Why do our movement joints keep failing?
The way it has failed normally tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
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.

Expansion joint sealing around Rainham: how the place shapes the job
Rainham lies within about 3 miles of the sea. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. Rainham is about 32 miles from central London. Warehousing clusters around the motorways that ring and radiate from London.
A healthcare site such as Medway Maritime Hospital, 3.2 miles north-west of Rainham, depends on car parks, ramps and service yards whose joints take traffic all day. For estates staff at a university like University of Greenwich - Medway, which lies north-west of Rainham, building and paving joints are part of the planned maintenance list.

What we are called out for in Rainham
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes.
Typical triggers for a call:
- Rain penetration at brick or block movement joints
- Joints packed with grit and debris
- Leaks through car park deck joints onto the level below
- Hardened, cracked sealant on exposed facades
Another example is Gillingham Business Park, 1.6 miles west of Rainham, where floors and yards would be done in stages around the occupiers.

Our process
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Parking and loading for town-centre jobs in Rainham are worth mentioning when you send details. Industrial and business units typically have yard or car park space.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- 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
- Let us know about inductions and permits
- Warn occupants and staff about the work
- Confirm the product named in the specification
Ask for a quote
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 photos and a few notes.
Related advice
Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Commercial clients in Rainham
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Why it’s worth doing now in Rainham
Doing joint resealing alongside other planned works can save on access. But joints already letting water in shouldn’t wait for a programme. Urgent joints now, the rest later, is often the sensible plan. In a town like Rainham, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.
