About our expansion joint sealing in Dean
Brickwork and blockwork walls have vertical movement joints at intervals 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 with primer where the maker calls for it. We work on car park decks and ramps, blockwork control joints and precast concrete panel joints, and what we are called in for most is joints where the bead has lost adhesion and brittle, chalky sealant on external joints. A specialist sealant contractor works differently from a general builder: in Dean, that means joint design, primers and backing rod as standard.
Smaller community and commercial buildings around Dean have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Site staff or a sealant specialist?
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.
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.
Building owners, agents and FMs in Dean
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Slabs, ramps and loading bays in Dean
Dean has two named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. At about 60 miles from central London, Dean is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift.
Schools such as Bishops Waltham Infant School have movement joints in their walls and floors that are easy to overlook. Phasing is what makes joint work possible on busy sites such as Waltham Business Park (2.4 miles south of Dean): one bay, aisle or car park row at a time.
Dean is about 6 miles north-east of Hedge End, in Hampshire. Across the SO32 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 723 places in Hampshire. There’s a separate page for Southampton, about 9 miles away.

What we’re called out for in Dean
When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again, so we check width and movement before quoting.
These are often picked up first by site or facilities staff:
- Expansion joints filled with dirt and stones
- New sealant over old, now failing
- Arrises breaking up along floor joints
- Torn sealant in brick or block movement joints
On a site such as Swanmore Business Park (1.9 miles south of Dean), the movement joints are in car park slabs, paving and building elevations.
What to look for in a quote
- How the joint faces will be prepared and primed
- What level of public liability insurance do they hold?
- How they’ll work around occupants
- Are they CHAS accredited or on Constructionline?
Questions about Dean
Do you cover business parks and estates near Dean, such as Swanmore Business Park?
Yes. Our area takes in Dean and its surroundings, with estates and business parks such as Swanmore Business Park included. Photos and a short description are enough for a first look.
Must our site in Dean stop work while the joints are done?
Typically not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
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.
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.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
How the job changes by surface
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing, and tell you if the joint looks too narrow for the movement.
On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Dean need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
What we need from you
- Tell us which areas need to stay in use
- Warn occupants and staff about the work
- Send any specification or drawings in advance
Getting a fixed quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
Advice
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Keep stones and debris out of open joint lines
- Reopen bays and walkways only after the stated cure time
- Put movement joints on the planned maintenance inspection round
- Inspect exposed joints once the cold weather has passed
Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. If anything looks wrong, speak to us on 01277 525 020 or use the quote form with photographs.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort so you can prioritise and budget. We’ll tell you which movement joints need doing now and which can wait.
