Different surfaces, different methods
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement flagging broken arrises before sealing.
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. The product must bond to both substrates and cope with the movement priming where the maker calls for it.
Expansion joint sealing in Duton Hill
Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic, and we will confirm the choice in the quote. Most enquiries involve brittle, chalky sealant on external joints and water getting into the wall through a failed joint, across blockwork control joints, precast concrete panel joints and cladding panel joints.

Jobs around smaller places like Duton Hill are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- A joint that has to be widened or re-detailed before it can work
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Crumbling edges that would give a new bead nothing sound to grip
If you are not sure, just call 01277 525 020 or email us and we will give you a straight answer.

Floors, slabs and movement joints in Duton Hill
Duton Hill is about 34 miles from central London. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift. Duton Hill sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.
Parks like Williams Field Business Centre, 1.9 miles west of Duton Hill, combine paved areas, car parks and building elevations, each with joints that move.

Aftercare for building managers
For the best life from the joints:
- Keep traffic off new joints until the cure time is up
- Raise snow-clearing blades over deck joints where possible
- Plan racking layouts so feet don’t land on a joint
- Clear dirt from joint lines during routine cleaning
Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it. Sealing the joint promptly stops it at source.
On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and we clear our waste as we work. If others near Duton Hill need work, visits can be combined. A fixed quote is given before anything starts.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Getting the site ready

Other services in Duton Hill
Common problems we fix in Duton Hill
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.
It’s worth sending us details if you spot any of the following:
- Car park joints leaking onto vehicles below
- Expansion joints filled with dirt and stones
- Rain penetration at brick or block movement joints
- Expansion joints split through the centre of the bead
In a school such as Putteridge High School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Your questions answered
Will our site in Duton Hill have to close for joint sealing?
Normally not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.
Is Duton Hill too far out for you?
No. Places such as Duton Hill are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Can the sealant be colour-matched?
In many cases, 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.
What timescale should we allow for resealing expansion joints?
It typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Timings are set out in the quote.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
