How we handle expansion joint sealing in Southington
Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. The enquiries we see most involve previous reseals laid over old sealant and damp inside where a wall movement joint has failed, on podiums and floor movement joints, car park decks and ramps and precast concrete panel joints. One point of contact handles commercial sealant work in Southington from the first photographs to the final walk-round, for single jobs and planned programmes alike.
For a site near Southington, measurements and photos up front mean one trip where possible, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.
A 12-month guarantee applies to all our work in Hampshire. Should something we installed fail, call the office on 01277 525 020 or use the quote form and we will come back to it.

When to call us in Southington
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.
Common reasons buildings call us in:
- Hardened, cracked sealant on exposed facades
- Layers of sealant in a movement joint
- Sealant pulling off the joint face
- Torn sealant in brick or block movement joints
On industrial estates such as Ardglen Industrial Estate, 3 miles to the west of Southington, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
What your quote should include
- Are they CHAS accredited or on Constructionline?
- Whether old or failed sealant will be cut out, not overlaid
- How they handle RAMS and site documents
- How joint depth will be controlled
Why it’s worth doing now in Southington
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open. Tell us what has to stay open and we will plan around it. Older rural buildings around Southington move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Keep scrapers and ploughs from dragging across joint sealant
- Put movement joints on the planned maintenance inspection round
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Keep product details with the building records for the next reseal
Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth and we will tell you when each bay or area can reopen. Keeping the area coned off until then avoids tyre marks and damage.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We will tell you which movement joints need doing now and which can wait.
What affects the price in Southington
Each job is priced on its own details. The main factors are:
- Whether old sealant has to be cut out first
- The size and state of each joint
- How much there is to seal
- Site requirements such as inductions and permits
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What to include in your enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Asbestos survey details if the building is older
- Any specification or named product
- Where the site is, with the postcode
- Any dates the work must fit around
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Proprietary pre-formed expansion joint systems
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think.
