About our floor joint sealing in St Mary's
Open joints take a beating from forklift and pallet-truck wheels. Every pass chips at the bare concrete edge, and over time a neat cut turns into a ragged channel. A properly filled joint carries the wheel over and protects both arrises, which is kinder to trucks, loads and operators. Site teams most often ask us about open saw cuts full of debris and old filler gone hard, cracked or loose, on saw-cut induced joints, construction joints and retail and showroom floors. Whether you call it commercial sealant work, mastic application or joint sealing, the work in St Mary's is the same: the right product in a properly prepared joint.
Work in a smaller place like St Mary's is usually one building at a time. That way the right materials come on the day and the job is done in one visit where possible.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Why deal with it now?
Duct tape or a general builders’ sealant can seem to buy some time. None of it is designed for wheel loads, and it typically ends up dragged across the floor. A product chosen for the traffic and movement does the job once. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
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.

Slabs, ramps and loading bays in St Mary's
St Mary's sits close to the coast, within about 1 mile. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so a failed joint lets more in and the edges break up sooner. St Mary's sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.
Large sites such as Royal South Hants Hospital, 0.5 miles north of St Mary's, have car parks, service roads and long elevations with movement joints in brick and panels. Across sites such as Basepoint Business Centre (0.5 miles south-east of St Mary's), floor and movement joints can be sealed in phases so units keep working.
St Mary's is about 1 mile south of Southampton, in Southampton. We send applicators to St Mary's for floor joints, handled exactly as we handle every other area. Our Southampton coverage takes in 30 places, large and small.
Business premises anywhere in SO14, SO15 and SO18 are within our area for floor joints. For a building on New Road, Ogle Road and Marsh Lane or nearby, we can quote for floor joints. We also cover Northam (1 mile north-east), Inner Avenue (1 mile north), Peartree Green (1 mile east), Southampton (1 mile north) and Bitterne Manor (1 mile north-east). A short drive away, we cover Harefield (3 miles east), Maybush (3 miles north-west), Coxford (3 miles north-west), Lordswood (3 miles north-west), Mansbridge (3 miles north-east) and Redbridge (3 miles west).

Aftercare for building managers
After handover, these steps help:
- Expect fillers on young slabs to need a top-up
- Check joint lines on busy aisles regularly
- Mention any aggressive cleaning regime at quote stage
- Hold traffic back until the product has cured
If a joint we filled starts to break up within 12 months, tell us and we’ll arrange a look. After that, a check before your busiest period keeps small repairs small.
Grit in an open joint does damage every time a wheel crosses it. Filling it ends that cycle while it is still a straightforward job.

On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a site in St Mary's, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- Each area is assessed for joint width, arris damage and the wheels that cross it.
- The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
- Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
- We vacuum each run and prime it if the chosen product requires a primer.
- We fill each joint to depth and finish it flush so wheels roll straight across.
- Each phase reopens when the product is ready for wheels, then we start the next.
Before we start on site
- Point out any areas we must not close
- Have the specification and drawings to hand
- Make sure the joints can be reached

Owners, agents and contractors
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
When to call us in St Mary's
Loading bay joints are exposed to wind, wet tyres and bigger temperature swings on top of the heaviest turning movements. They are often the first on a site to break down.
Things that typically lead to an enquiry:
- Failing joints at loading bays and dock doors
- Trucks and loads jolting over damaged joints
- Broken arrises where pallet trucks cross
- Saw-cut joints left open and packed with grit
Centres like Marlands Shopping Centre (to the west of St Mary's) have mall floors and service decks whose joints carry steady traffic.

Questions we are asked in St Mary's
Does a coastal location like St Mary's affect which sealant is used?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Is a hospital such as Royal South Hants Hospital somewhere you can work?
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.
How do we get a quote for floor joints?
Approximate metres of joint, photographs of typical and worst areas, and a floor plan let us give a quick quote. We can visit where that helps, and you can call 01277 525 020 or send photos by email to arrange it.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Is colour matching possible?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
