How we handle expansion joint sealing in King's Somborne
Long runs of brick or block have movement joints built in. 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. If you have layers of sealant in a movement joint and debris jammed in movement joints, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in King's Somborne, that means joint design, primers and backing rod as standard.
Around smaller places such as King's Somborne, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Expansion joint sealing in King's Somborne: the local picture
At about 67 miles from central London, King's Somborne is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift. King's Somborne sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.
For a school such as King's Somborne Church of England Primary School, playground and building joints can be done in the holidays. Hospital campuses such as Romsey Community Hospital (to the south of King's Somborne) grow in stages, leaving movement joints wherever new blocks meet old.
King's Somborne is about 6 miles north of Romsey, in Hampshire. Looking for expansion joint sealing in King's Somborne? We can help. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. There’s a separate page for Southampton, about 12 miles away.

How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around King's Somborne, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
What we need from you
- Flag any permit to work we will need
- Share the asbestos register for older buildings
- Point out any areas we must not close

Questions we are asked in King's Somborne
Is a smaller place like King's Somborne outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will our site in King's Somborne have to close for joint sealing?
Normally not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we will plan from there.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can staff carry on working while you’re here?
Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.
How do we ask for a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email the details over. Include photos or drawings if you have them.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Note which joints were done, when, and with what
- Keep stones and debris out of open joint lines
- Inspect exposed joints once the cold weather has passed
- Put movement joints on the planned maintenance inspection round
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file, so the next reseal starts with the facts.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it. Resealing early limits the damage.
For managing agents and facilities managers
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- How accessible the joints are
- The size and state of each joint
- How much existing material needs removing
- Quantities, in metres or numbers
A quote for movement joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
What to include in your enquiry
Whether it’s one area or a whole building, these details speed things up:
- Your programme or deadline
- What the building is and how it’s used
- Clear photos of the problem areas
- The site address and postcode
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email the details over.
Why act early in King's Somborne
Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use, compared with a full closure. We agree phasing with you before work starts. One visit to deal with every failing joint makes more sense than several trips to a place like King's Somborne, rather than one at a time. Photos of every joint help us quote for the whole job.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Joints too narrow for the movement, which need redesigning by the engineer
If you are not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer.
