Expansion joint sealing for businesses in Otterbourne
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
After the work
A few simple habits keep the new joints working:
- Include every elevation and deck joint in periodic inspections
- Keep stones and debris out of open joint lines
- Look over external and deck joints after a hard winter
- Leave barriers in place until fresh joint sealant has cured
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints.
On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles. Sealing the joint promptly stops it at source.
Expansion joint sealing in Otterbourne, done properly
If you need expansion joint sealing in Otterbourne, start with photographs and joint lengths. We will come and look where photos don’t show enough, then send a fixed quote that names the sealant. To discuss the joints first, ring 01277 525 020 or send details through our quote form. Site teams most often ask us about water dripping through deck or ramp joints and spalled or broken joint edges in floors and decks, across brickwork movement joints, precast concrete panel joints and podiums and floor movement joints.

Why act early in Otterbourne
A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed, and we will say so before quoting. Around Otterbourne, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Your questions answered
Is hospital work, at somewhere like Wessex Hospital, something you do?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Wessex Business Park, near Otterbourne, within your area?
Yes. Our area takes in Otterbourne and its surroundings, with estates and business parks such as Wessex Business Park included. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Can you send site paperwork?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Which product is best for expansion joints?
The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Surface by surface
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.
Podium joints
Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

Signs you need expansion joint sealing in Otterbourne
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.
Typical triggers for a call:
- Joints where the bead has lost adhesion
- Hardened, cracked sealant on exposed facades
- Debris jammed in movement joints
- Previous reseals laid over old sealant
At places like Hazeley Enterprise Park, which lies north-east of Otterbourne, joints are sealed a section at a time so operations carry on.
What to look for in a quote
- Their approach to joint depth and backing
- Who will actually carry out the work
- Proof of insurance
- Which product they’ll use, and why it suits the joint
Owners, agents and contractors
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
How a job runs
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Otterbourne need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We look at the joints, their width and how they’ve failed.
- Next, we fix a price and confirm the sealant we propose for the movement.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
Before we start on site
- Let us know about inductions and permits
- For older buildings, check the asbestos register before work
- Confirm the product named in the specification

Expansion joint sealing in Otterbourne: the local picture
Less than 3 miles from Otterbourne there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Rainfall across the South East, Otterbourne included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.
University campuses such as University of Winchester, 3.6 miles to the north of Otterbourne, have car parks, paved walkways and building elevations with movement joints. Office parks like Wessex Business Park (1.8 miles south-east of Otterbourne) have decks, ramps and clad elevations whose joints take movement every day.
