Expansion joint sealing in Lower Upnor
A movement joint only works while its seal does. Once it fails, water, grit and debris get in; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on cladding panel joints, precast concrete panel joints and podiums and floor movement joints, and what we are called in for most is arrises breaking up along floor joints and damp inside where a wall movement joint has failed. Whoever orders the work in Lower Upnor, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Jobs around smaller places like Lower Upnor are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What sets the cost
Before we quote, we look at:
- How accessible the joints are
- Travel to remote or island sites
- Quantities, in metres or numbers
- Working within restricted access windows
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Before you send an enquiry
To price the job accurately, we need to understand the site. Send us:
- Specification clauses that apply
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
- A wide shot and a close-up of the area
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or send photos by email with what you know.

Why it’s worth doing now in Lower Upnor
A torn seal left alone usually gets worse. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Acting at the first split keeps the cost down. One visit to deal with every failing joint makes more sense than several trips to a place like Lower Upnor. Send photographs of each area and we will quote for the lot.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What the job involves on each surface
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it.
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.
From enquiry to sign-off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Lower Upnor, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First the joints are inspected, widths measured and the type of failure noted.
- 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.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Getting the site ready
- Make sure the joints can be reached
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements

Advice
Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Damaged metal nosings or cover plates over a joint
- Crumbling edges that would give a new bead nothing sound to grip
- Joints too narrow for the movement, which need redesigning by the engineer
If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think.
Surfaces we seal
- Brickwork movement joints
- Blockwork control joints

- Podiums and floor movement joints

Slabs, ramps and loading bays in Lower Upnor
The sea is no more than about 2 miles from Lower Upnor. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, and edges left open tend to break up faster. Lower Upnor is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.
A healthcare site such as Medway Maritime Hospital (2.3 miles south of Lower Upnor) depends on car parks, ramps and service yards whose joints take traffic all day. Retail centres such as Strood Retail Park (to the south-west of Lower Upnor) have floors, service yards and car parks with joints under constant traffic. Across sites such as Castle View Business Centre, which lies south-west of Lower Upnor, floor and movement joints can be sealed in phases so units keep working.
