Honest limits
Honesty saves time and money. New sealant won’t cure:
- A joint that has to be widened or re-detailed before it can work
- Proprietary pre-formed expansion joint systems
- Cracking or settlement that calls for an engineer’s assessment

Expansion joint sealing in Hanscombe End
A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on precast concrete panel joints, podiums and floor movement joints and blockwork control joints, and the failures we are asked to look at most are previous reseals laid over old sealant and weathered movement joint sealant that no longer flexes. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hanscombe End, preparation and product choice get the time they need.
Smaller community and commercial buildings around Hanscombe End have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
Work we carry out in Hertfordshire comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email the details over and we’ll arrange a return visit.

Hanscombe End: questions and answers
Can you work at a site such as Manor Farm Business Park, by Hanscombe End?
Yes, sites like Manor Farm Business Park are within our area, along with the rest of Hanscombe End. Photos and a short description are enough for a first look.
Is Hanscombe End too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Do you use silicone or polyurethane in movement joints?
It depends on the movement, exposure and traffic. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints.
Can a joint be sealed if the edges are broken?
Spalled edges need repairing before a new seal will last, and we’ll point out where that’s the case. Sealing over them leads to early failure.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Signs you need expansion joint sealing in Hanscombe End
Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.
Clients typically get in touch after noticing something like this:
- Spalled or broken joint edges in floors and decks
- Water getting into the wall through a failed joint
- Debris jammed in movement joints
- Sealant peeling off one face of the joint
For buildings at a park such as Manor Farm Business Park (1.2 miles south-west of Hanscombe End), brick and panel movement joints are easy to forget until one leaks.

Other services in Hanscombe End
Different surfaces, different methods
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it.
Podium joints
Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.
Cost factors for movement joints
The price varies from site to site. It mainly depends on:
- The size and state of each joint
- The product specified
- Working within restricted access windows
- Site requirements such as inductions and permits
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Details that help us quote
To price the job accurately, we need a clear picture of the site. Useful things to include:
- The type of building and who uses it
- A wide shot and a close-up of the area
- Drawings or a marked-up plan, if available
- The asbestos register, for older buildings
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Smaller jobs around Hanscombe End can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces, 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.
Before we start on site
- Move anything stored against the joints
- Warn occupants and staff about the work
- Arrange parking or a loading space

After the work
For the best life from the joints:
- Record the sealant used and the date in the O&M file
- Avoid parking heavy plant or pallets on joint lines
- Include every elevation and deck joint in periodic inspections
- Keep traffic off new joints until the cure time is up
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check and long before edges start to break. If anything looks wrong, ring 01277 525 020 or email the details over with photos.
An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall, turning a sealant job into a repair job. A sound seal keeps the joint working.
