About our expansion joint sealing in Woolston
We’ve been sealing expansion and movement joints for over 20 years, for main contractors, FMs, managing agents and building owners. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. The enquiries we see most involve arrises breaking up along floor joints and new sealant over old, now failing, on car park decks and ramps, precast concrete panel joints and brickwork movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Woolston it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around Woolston, most floor and movement joint jobs are single buildings or yards. Getting widths, depths and traffic details up front means one visit, not two.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or send photos by email and we’ll come back to it.

After the work
For the best life from the joints:
- Treat a small split as a warning, not a cosmetic issue
- Keep scrapers and ploughs from dragging across joint sealant
- Keep product details with the building records for the next reseal
- Put movement joints on the planned maintenance inspection round
Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- A joint that has to be widened or re-detailed before it can work
- Crumbling edges that would give a new bead nothing sound to grip
If you are not sure, just call 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Common questions from Woolston clients
Our building in Woolston is near the coast: does that change the sealant?
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.
Will you take on work at estates like Basepoint Business Centre, close to Woolston?
Yes. Our area takes in Woolston and its surroundings, with estates and business parks such as Basepoint Business Centre included. To start, just speak to us on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Why do our movement joints keep failing?
Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting, rather than replacing like for like.
What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- How accessible the joints are
- Location, for remote and island sites
- Removal of failed or old sealant
- Phasing around occupants
The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote when you’re ready.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- The postcode of the building
- Asbestos survey details if the building is older
- What the building is and how it’s used
- Anything awkward about access or site hours
To get a fixed quote, give us a call on 01277 525 020 or send photos by email, telling us the site location and the nature of the job. Our quote form is another easy route.

What we’re called out for in Woolston
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens.
Look out for the following:
- Brittle, chalky sealant on external joints
- Leaks through car park deck joints onto the level below
- Joints packed with grit and debris
- Sealant peeling off one face of the joint
For an estate such as Royal South Hants Hospital, 1.6 miles to the north-west of Woolston, the joints in ramps, decks and long building elevations all need attention over time.
What your quote should include
- What the guarantee covers, and for how long
- Are they CHAS accredited or on Constructionline?
- Can the work be phased to keep areas open?
- How joint depth will be controlled
From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. If neighbouring businesses or buildings around Woolston need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Finished joints are checked and backed by our 12-month guarantee.
Getting the site ready
- Confirm the product named in the specification
- Let us know about inductions and permits
- For older buildings, check the asbestos register before work

When to bring in a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Expansion joint sealing in Woolston: the local picture
With the shore within about 1 mile, Woolston counts as a coastal location. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.
At places like Central Trading Estate, 1 mile to the north-west of Woolston, joints are sealed a section at a time so operations carry on. Retail centres such as Marlands Shopping Centre (to the north-west of Woolston) have floors, service yards and car parks with joints under constant traffic.
Woolston is about 2 miles south-east of Southampton, in Southampton. Across the SO19 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Southampton, 30 places are covered, Woolston among them.
