Common problems we fix in Northmoor
Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it so edge repair has to come before resealing.
Most enquiries start with one or more of the following:
- Joints where the bead has lost adhesion
- Debris jammed in movement joints
- Water getting into the wall through a failed joint
- Movement joints with split or torn sealant
Large sites such as Abingdon Community Hospital (to the south-east of Northmoor) have car parks, service roads and long elevations with movement joints in brick and panels.
Questions to ask before you book
- Whether primer will be used where the manufacturer specifies it
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their plan for phasing and protecting the area
- Their public liability cover
Why act early in Northmoor
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now because damage continues. We can split the scope into urgent and planned. Older rural buildings around Northmoor move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

How a job runs
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Northmoor, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- 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.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Getting the site ready
- For older buildings, check the asbestos register before work
- Clear stock, furniture or equipment away from the joints
- Have the specification and drawings to hand
Ask for a quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Advice
General trades versus a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Where floor joints take the most wear near Northmoor
Northmoor lies roughly 58 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London. Rainfall across the South East, Northmoor included, is lower than in many parts of the UK. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint.
University campuses such as Azad University in Oxford (to the north-east of Northmoor) have car parks, paved walkways and building elevations with movement joints. Warehouse floors on estates like Lakeside Industrial Estate, 1.7 miles north-west of Northmoor, carry pallet trucks and forklifts over every saw-cut joint.

How the quote is worked out
Each job is priced on its own details. The things that drive the figure:
- How much existing material needs removing
- Specialist products, such as fire-rated or hygienic sealants
- Access and working height
- How much there is to seal
We don’t publish prices, since every building and every scope is different. Call for a quote.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- The postcode of the building
- Anything awkward about access or site hours
- Any specification or named product
- Asbestos survey details if the building is older
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email the details over.
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Joints too narrow for the movement, which need redesigning by the engineer
- Concrete or masonry repairs along the arrises
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
If you’re not sure, just call the office on 01277 525 020 or email the details over and we will give you a straight answer.

Questions about Northmoor
Will you take on work at estates like Lakeside Industrial Estate, close to Northmoor?
Yes. Estates, retail parks and business parks around Northmoor, Lakeside Industrial Estate among them, are all within reach. To start, just phone 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Is a hospital such as Abingdon Community Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
How long will the joint resealing take?
The metres of joint, the access and the amount of removal decide it. As a guide, it usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing.
Do you reseal car park expansion joints?
Yes. Let us know the opening hours and which levels or bays have to stay available, and we’ll plan the phasing around it.
Do the joint edges need to be sound before sealing?
A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we’ll say so when we quote.
What’s the difference between an expansion joint and a movement joint?
The general name is movement joint, and expansion joint is one common type. In everyday use the two names are often swapped.
