Commercial clients in Chilworth
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Chilworth can form part of a wider programme.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Expansion joint sealing in Chilworth
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. We work on precast concrete panel joints, brickwork movement joints and cladding panel joints, and what we’re called in for most is joints packed with grit and debris and brittle, chalky sealant on external joints. One point of contact handles commercial sealant work in Chilworth from the first photos to the final walk-round, whether it’s one building or several.
For a site near Chilworth, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Warehouse floors and decks around Chilworth
The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints. At about 68 miles from central London, Chilworth is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift.
Another example is Chestnut Avenue Retail Park, 1.2 miles to the north-east of Chilworth, where floors and yards would be done in stages around the occupiers. A campus such as University of Southampton, 2.1 miles to the south of Chilworth, has long runs of movement joint in its buildings, decks and paving.
Chilworth is about 2 miles south-west of Chandler's Ford, in Hampshire. Anywhere in SO16, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 723 places in Hampshire, from busy centres to rural villages.
Postcode districts covered here: SO16 for movement joints. For a building on Heatherlands Road, Roman Road and Pinelands Road or nearby, we can quote for movement joints.

What’s near Chilworth
Around Chilworth, our work takes us to commercial buildings near Lakeside Country Park and Saint George Catholic Voluntary Aided College Southampton, among other places. The nearest railway station is Swaythling station, about 1.9 miles south-east of the centre. Other landmarks nearby include Princess Anne Hospital (1.9 miles south-west) and Marlands Shopping Centre (3.6 miles south). Green spaces nearby include Flexford Nature Reserve.
General trades versus a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
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 where general trades tend to cut corners.
Cost factors for movement joints
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Induction, permit and paperwork requirements
- The product specified
- The total length or number of joints
- Access and working height
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
We can often quote from photographs and a few details. Please tell us:
- Your programme or deadline
- A wide shot and a close-up of the area
- The product your specification calls for
- Access details, including height

When something else is needed
Honesty saves time and money. New sealant won’t cure:
- Changing the joint layout or spacing of a structure
- Crumbling edges that would give a new bead nothing sound to grip
- Movement on a scale no sealant is meant to absorb
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Blockwork control joints
- Cladding panel joints
- Brickwork movement joints
- Podiums and floor movement joints
- Precast concrete panel joints
- Car park decks and ramps
Do you need expansion joint sealing in Chilworth?
On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant. A sealant that isn’t trafficable won’t last there.
Site and facilities staff are often the first to spot these:
- Joints where the bead has lost adhesion
- Spalled or broken joint edges in floors and decks
- Rain penetration at brick or block movement joints
- Water dripping through deck or ramp joints
In a school such as Cantell School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
Questions to ask before you book
- The terms of the workmanship guarantee
- The named product and why it was chosen
- Whether old or failed sealant will be cut out, not overlaid
- Whether their applicators hold CSCS cards
On site: what to expect
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Chilworth can be grouped with others nearby. You will have a fixed quote before work starts.
- First the joints are inspected, widths measured and the type of failure noted.
- 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.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Agree which areas must stay open
- Explain the parking and delivery arrangements
- For older buildings, check the asbestos register before work

Common questions from Chilworth clients
Is a smaller place like Chilworth outside your area?
Not at all. Chilworth is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Is a hospital such as Princess Anne Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How long will the joint resealing take?
Expect a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints and phased work can stretch that to suit your site. We will confirm when each area can be used again.
What will the job cost?
Each job is quoted on its own details. To get one, call 01277 525 020 or email the details over.
Why has the sealant in our expansion joints split?
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.
Is colour matching possible?
It depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
