About our expansion joint sealing in Andover
Long runs of brick or block have movement joints built in. 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. The enquiries we see most involve joints where the bead has lost adhesion and water getting into the wall through a failed joint, across brickwork movement joints, precast concrete panel joints and blockwork control joints. A single leaking joint is often how a building in Andover first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In a town the size of Andover, floor joints are mostly in industrial and trade units, supermarkets and car parks. Small units are often busy, so joints are done at times that suit the occupier.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Common problems we fix in Andover
Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.
What tends to prompt an enquiry:
- Sealant peeling off one face of the joint
- Arrises breaking up along floor joints
- Expansion joints split through the centre of the bead
- Water getting into the wall through a failed joint
Large sites such as Andover Hospital (Grounds), 0.6 miles to the north-west of Andover, have car parks, service roads and long elevations with movement joints in brick and panels.
Questions to ask before you book
- Can the work be phased to keep areas open?
- Will CSCS-carded applicators be on site?
- The terms of the workmanship guarantee
- Whether old or failed sealant will be cut out, not overlaid
Why act early in Andover
Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. For businesses and landlords in Andover, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.
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 fixed quote and we’ll explain how it’s made up.

On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. If you have more than one building in Andover, they can often be done on the same visit. Give us your access times and we’ll fit the work in.
- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Have the specification and drawings to hand

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Where floor joints take the most wear near Andover
At least three named trading, business or retail sites lie within about 3 miles of Andover. Their warehouses, yards and car parks are exactly where joints take the most punishment. Andover lies roughly 63 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.
Another example is Churchill Retail Park, 0.5 miles north-east of Andover, where floors and yards would be done in stages around the occupiers. Schools like St John the Baptist Catholic Primary School often have long brick elevations with movement joints that age quietly.
Andover is about 17 miles west of Basingstoke, in Hampshire. Across the SP10 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 723 places in Hampshire. Southampton is covered too, some 21 miles away.
Work on movement joints is covered throughout SP10 and SP11, for business premises of every kind. If your site is on High Street, Goddard Square and London Road or close by, we can quote for movement joints. Being close to the A303 and A342, Andover is easy to get to with materials and equipment. Sites close to Andover are covered too, including Picket Twenty (1 mile east), East Anton (1 mile north-east), Knights Enham (1 mile north), Finkley Down (2 miles north-east) and Picket Piece (2 miles east). Further afield, our area takes in Winchester (13 miles south-east), Romsey (15 miles south), Hyde (12 miles south-east), Tidworth (8 miles west), Weeke (12 miles south-east) and Kempshott (15 miles east). As one of the bigger centres in Hampshire, Andover has a broad mix of commercial, public and industrial buildings.
Landmarks near Andover
Locally, jobs take us to sites close to The Angel Inn, Winton Community Academy and Winton Community Academy and the streets around them. The nearest railway station is Andover station, about 0.5 miles west. Well-known places in the area include Andover War Memorial Hospital (0.7 miles north-west) and Andover Museum (under half a mile east). For a walk, there’s Anton Lakes and Mill Lake.
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Keep stones and debris out of open joint lines
- Record the sealant used and the date in the O&M file
- Check joints after long freezing spells
- Brief car park operatives to protect joint lines during winter clearance
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it and it can affect the structure over time. Sealing the joint promptly stops it at source.

Questions about Andover
Can you work at a site such as Northern Avenue Retail Park, by Andover?
Yes. Our area takes in Andover and its surroundings, with estates and business parks such as Northern Avenue Retail Park included. A few photos and the unit address let us price the work.
Do you take on work at healthcare sites like Andover Hospital (Grounds)?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you send site paperwork?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
What will the job cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
