Common questions from Coxford clients
Is Coxford too far out for you?
No. Places such as Coxford are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is a hospital such as Southampton General Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What causes movement joint sealant to fail?
The way it has failed typically tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Broken edges are a third possibility.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Does the weather affect joint sealing?
Outside work depends on conditions: rain, frost and condensation all stop sealant bonding. Indoor joints can normally carry on regardless.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Are expansion joints and movement joints the same thing?
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.
How we handle expansion joint sealing in Coxford
Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied, primed where the manufacturer specifies. Most enquiries involve new sealant over old, now failing and arrises breaking up along floor joints, on brickwork movement joints, podiums and floor movement joints and precast concrete panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Coxford, that means joint design, primers and backing rod as standard.
Around places the size of Coxford, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Record the sealant used and the date in the O&M file
- Leave barriers in place until fresh joint sealant has cured
- Keep stones and debris out of open joint lines
- Treat a small split as a warning, not a cosmetic issue
Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.
What the job involves on each surface
Podium joints
Podium joints often sit within a waterproofing system. 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
A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing.
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
What affects the price in Coxford
There’s no standard rate for sealant work, because every site is different. What we look at:
- Quantities, in metres or numbers
- Access and working height
- Whether the work must be split into stages
- Travel to remote or island sites
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Useful things to include:
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
- The product your specification calls for
- Any dates the work must fit around
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Do you need expansion joint sealing in Coxford?
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 and it often shows on rushed work.
It’s worth sending us details if you spot any of the following:
- Layers of sealant in a movement joint
- Arrises breaking up along floor joints
- Brittle, chalky sealant on external joints
- Water getting into the wall through a failed joint
Schools such as Shirley Warren Primary & Nursery School have movement joints in their walls and floors that are easy to overlook.

Warehouse floors and decks around Coxford
Coxford sits close to the coast, within about 2 miles. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so a failed joint lets more in and the edges break up sooner. Coxford has at least three 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.
Across sites such as Shirley Retail Park, which lies east of Coxford, floor and movement joints can be sealed in phases so units keep working. University campuses such as University of Southampton (to the east of Coxford) have car parks, paved walkways and building elevations with movement joints.

Our process
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Work in places the size of Coxford is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- 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.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
What we need from you
- Move anything stored against the joints
- Have the specification and drawings to hand
- Send your site hours and access windows
