About our expansion joint sealing in Kempshott
Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. We work on blockwork control joints, podiums and floor movement joints and car park decks and ramps, and the usual reasons a site gets in touch are damp inside where a wall movement joint has failed and debris jammed in movement joints. Most enquiries from Kempshott start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around Kempshott, most floor and movement joint jobs are single buildings or yards, so we gather photos and measurements first. That way the right materials come on the day and the job is done in one visit where possible.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

- We assess the joints on site or from photographs, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- 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.

Expansion joint sealing in Kempshott: the local picture
Kempshott lies roughly 48 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London. The South East is one of the drier parts of the UK. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint.
Phasing is what makes joint work possible on busy sites such as St Michael's Retail Park (1.5 miles east of Kempshott): one bay, aisle or car park row at a time. A healthcare site such as Basingstoke and North Hampshire Hospital, 2.8 miles to the north-east of Kempshott, depends on car parks, ramps and service yards whose joints take traffic all day.
Kempshott is about 2 miles south-west of Basingstoke, in Hampshire. We send applicators to Kempshott for movement joints. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. Reading is covered too, around 16 miles from Kempshott.
Anyone looking for expansion joint sealing in RG22 and RG23 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Kempshott can sit alongside others in a wider programme across Hampshire.
When to bring in a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Questions we’re asked in Kempshott
Do you cover business parks and estates near Kempshott, such as Brighton Hill Retail Park?
Yes. Our area takes in Kempshott and its surroundings, with estates and business parks such as Brighton Hill Retail Park included. Photos and a short description are enough for a first look.
Do you take on work at healthcare sites like Basingstoke and North Hampshire Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Are expansion joints and movement joints the same thing?
They’re closely related. Both let materials grow and shrink with temperature, moisture and load while the sealant stops grit and water getting in.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
What will the job cost?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
Can you send site paperwork?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Keep racking legs and heavy point loads off floor joints
- Keep product details with the building records for the next reseal
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Keep traffic off new joints until the cure time is up
Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check and long before edges start to break. If anything looks wrong, ring 01277 525 020 or email the details over with photographs.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Sealing early protects the edges.
When something else is needed
We check first that sealant really is the fix. It won’t put right:
- A joint that has to be widened or re-detailed before it can work
- Proprietary pre-formed expansion joint systems
- Broken or spalled joint edges, which need repairing before any sealant goes in
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Signs you need expansion joint sealing in Kempshott
On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. The product has to be suited to the traffic.
Any of the following is a good reason to get the joints checked over:
- Torn sealant in brick or block movement joints
- Sealant peeling off one face of the joint
- Water getting into the wall through a failed joint
- Brittle, chalky sealant on external joints
Schools like Kempshott Junior School often have long brick elevations with movement joints that age quietly.
Questions to ask before you book
- How joint depth will be controlled
- What the guarantee covers, and for how long
- Health and safety accreditation such as CHAS
- Do they follow the manufacturer’s priming guidance?
