Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Concrete or masonry repairs along the arrises
- A joint that has to be widened or re-detailed before it can work
- Proprietary pre-formed expansion joint systems
If in doubt, call 01277 525 020 or send details through our quote form and we will say what we think.

Expansion joint sealing in Boyn Hill
Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. We work on precast concrete panel joints, blockwork control joints and brickwork movement joints, and the usual reasons a site gets in touch are layers of sealant in a movement joint and sealant pulling off the joint face. A single leaking joint is often how a building in Boyn Hill first comes to us: we look at the rest while we are there and tell you what we find.
Around places the size of Boyn Hill, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.
Our workmanship is guaranteed for 12 months, in Boyn Hill as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
For managing agents and facilities managers
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Boyn Hill can sit alongside others in a wider programme across Windsor and Maidenhead.
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’ll confirm with the quote.
Boyn Hill: questions and answers
Would you work within a site like St Mark's Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Can you work at a site such as Vanwall Business Park, by Boyn Hill?
Yes, sites like Vanwall Business Park are within our area, along with the rest of Boyn Hill. Photos and a short description are enough for a first look.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Is movement joint sealing guaranteed?
It’s backed by our 12-month guarantee. Tell us straight away if a joint we sealed gives trouble in that time.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
What happens if it’s left?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. We will flag where edges need repair before sealing. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Leave barriers in place until fresh joint sealant has cured
- Clear dirt from joint lines during routine cleaning
- Put movement joints on the planned maintenance inspection round
- Keep racking legs and heavy point loads off floor joints
Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. Should you spot a problem, you can phone 01277 525 020 or email a schedule or drawings and send a picture.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Sealing the joint promptly stops it at source.
Expansion joint sealing in Boyn Hill: the local picture
Boyn Hill sits in one of the drier corners of the country, the South East. 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. The 3 miles around Boyn Hill take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.
For a centre such as Cliveden View Shopping Centre, which lies north of Boyn Hill, the service yard and car park joints usually need attention first. For a school such as Larchfield Primary and Nursery School, playground and building joints can be done in the holidays. Parks like Vanwall Business Park (under half a mile north-west of Boyn Hill) combine paved areas, car parks and building elevations, each with joints that move.
Boyn Hill is about 1 mile south-west of Maidenhead, in Windsor and Maidenhead. Anywhere in SL6, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 60 places in Windsor and Maidenhead. For work in that direction, see our Reading page.
Commercial sites across SL6 are covered for movement joints. For a building on Lock Lane, Ross Road and Curls Road or nearby, send details and we’ll quote for movement joints.

Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If neighbouring businesses or buildings around Boyn Hill need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- 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.
- We strip out the old seal and prepare the faces, 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.
- 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.
Before we start on site
- Confirm the product named in the specification
- Tell us your opening times and when work is allowed
- Explain the parking and delivery arrangements
