How we handle expansion joint sealing in Cottonworth
Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load. If the arrises are already broken, we will say so before sealing. Site teams most often ask us about water dripping through deck or ramp joints and weathered movement joint sealant that no longer flexes, across cladding panel joints, car park decks and ramps and brickwork movement joints.

For a site near Cottonworth, 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.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

On site: what to expect
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Jobs in and around smaller places like Cottonworth are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- First, the joints are inspected for width, movement and the type of failure.
- 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.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Each joint is inspected and handed over with our 12-month guarantee.
Preparing the site
- Let us know about inductions and permits
- For older buildings, check the asbestos register before work
- Explain the parking and delivery arrangements

FAQs: Cottonworth
Does your area include sites such as Harewood Forest Industrial Estate, near Cottonworth?
Yes. Our area takes in Cottonworth and its surroundings, with estates and business parks such as Harewood Forest Industrial Estate included. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can you take on a job at a hospital such as Andover War Memorial Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work on car park ramps and decks?
Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement.
What do you charge?
Each job is quoted on its own details. For yours, phone 01277 525 020 or email the details over.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Can a joint be sealed if the edges are broken?
The edges have to be sound. Where they’ve broken up, we’ll tell you they need repairing first so you are not paying for a bead that won’t hold.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member.
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Keep product details with the building records for the next reseal
- Keep racking legs and heavy point loads off floor joints
- Look over external and deck joints after a hard winter
- Inspect movement joints alongside other routine building checks
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. Should you spot a problem, you can give us a call on 01277 525 020 or email drawings and photos and send a picture.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint, well after the seal first opened. Catching it early keeps the water outside.

A healthcare site such as Andover War Memorial Hospital (to the north of Cottonworth) depends on car parks, ramps and service yards whose joints take traffic all day.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we look at:
- Travel to remote or island sites
- The site’s rules and procedures
- How accessible the joints are
- How much existing material needs removing
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Details that help us quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- Specification clauses that apply
- The type of building and who uses it
- Whether an asbestos survey exists
- Access details, including height
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
When to call us in Cottonworth
The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it.
Most enquiries start with one or more of the following:
- Joints packed with grit and debris
- Leaks through car park deck joints onto the level below
- Spalled or broken joint edges in floors and decks
- Water getting into the wall through a failed joint
On industrial estates such as Harewood Forest Industrial Estate (2.9 miles north-east of Cottonworth), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Joints between different materials
Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces.
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.
