Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Saunderton Lee, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- 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.
Getting the site ready
- Agree which areas must stay open
- Arrange parking or a loading space

Expansion joint sealing in Saunderton Lee
Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. Site teams most often ask us about torn sealant in brick or block movement joints and weathered movement joint sealant that no longer flexes, on podiums and floor movement joints, blockwork control joints and cladding panel joints.

Questions about Saunderton Lee
Does your area include sites such as Crownfield Industrial Estate, near Saunderton Lee?
Yes. Our area takes in Saunderton Lee and its surroundings, with estates and business parks such as Crownfield Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Is Saunderton Lee too small for you to travel to?
Not at all. Saunderton Lee is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do the joint edges need to be sound before sealing?
Spalled edges need repairing before a new seal will last, and we’ll point out where that’s the case. A bead on a broken edge soon lets go.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
What happens if it rains on the day?
Outside work depends on conditions because a damp or frozen joint won’t take a proper bond. Internal floor joints are far less affected.
Do you offer coloured sealant?
It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Owners, agents and contractors
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Saunderton Lee can form part of a wider programme.
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Expansion joint sealing in Saunderton Lee: the local picture
Saunderton Lee is about 34 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.
Estates like Crownfield Industrial Estate, under half a mile to the south-east of Saunderton Lee, combine warehouse slabs, yards and loading bays, all with joints under wheels. For a school such as St John's Church of England Primary School, playground and building joints can be done in the holidays. Large sites such as The Paddocks Hospital (to the north of Saunderton Lee) have car parks, service roads and long elevations with movement joints in brick and panels.

What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Waterproofing layers buried beneath the sealant
- Movement on a scale no sealant is meant to absorb
- Changing the joint layout or spacing of a structure

How the job changes by surface
Joints between different materials
Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement.
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately.
Maintenance after handover
After handover, these steps help:
- Reopen bays and walkways only after the stated cure time
- Clear dirt from joint lines during routine cleaning
- Report split or peeling joint sealant early
- Raise snow-clearing blades over deck joints where possible
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one so you can prioritise and budget. We can suggest an order, worst joints first.
When to bring in 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. Getting these wrong normally costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
