South Oxhey: questions and answers
Would you work within a site like Watford General Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is South Oxhey too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
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.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Which product is best for expansion joints?
Whatever suits the joint and the specification. We name the proposed product in the quote so there are no surprises.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Expansion joint sealing for commercial buildings in South Oxhey
For movement joints in South Oxhey, photographs and approximate lengths are the best start. Send them through our quote form, and we will arrange a site visit if needed before issuing a fixed quote. To discuss the joints first, give us a call on 01277 525 020 or send details through our quote form. If you have new sealant over old, now failing and expansion joints split through the centre of the bead, we can help, on brickwork movement joints, blockwork control joints and podiums and floor movement joints alike. A specialist sealant contractor works differently from a general builder: in South Oxhey, that means joint design, primers and backing rod as standard.
Small units near places like South Oxhey are often converted farm buildings with new concrete floors. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.
A 12-month guarantee applies to all our work. If an installation problem shows up, give us a call on 01277 525 020 or email the details over and we will arrange a return visit.

Our process
At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Several jobs near South Oxhey can be grouped on one trip. Tell us your site hours and we will plan around them.
- We look at the joints, their width and how they’ve failed.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Agree which areas must stay open
- Send any specification or drawings in advance
- Tell us what induction or permit system the site runs
Quotes
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Why it’s worth doing now in South Oxhey
Resealing is usually the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. We will flag where edges need repair before sealing. In a smaller place such as South Oxhey, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Joints that move: notes for South Oxhey
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, and winter de-icing salt on car parks and ramps works into any open joint. South Oxhey lies roughly 15 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.
For a school such as Greenfields Primary School, playground and building joints can be done in the holidays. Sites like Watford General Hospital (to the north of South Oxhey) carry ambulances, deliveries and visitors’ cars over their road and deck joints. For an occupier at a site such as Wiggenhall Industrial Estate, which lies north of South Oxhey, the joints at loading doors and dock levellers normally see the hardest wear.
South Oxhey is about 2 miles north-west of Hatch End, in Hertfordshire. South Oxhey sits inside our coverage and the rest of Hertfordshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Movement on a scale no sealant is meant to absorb
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we will tell you honestly.

Different surfaces, different methods
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 priming where the maker calls for it.
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, typically low-modulus.
After the work
To get the most from the new sealant:
- Inspect movement joints alongside other routine building checks
- Clear dirt from joint lines during routine cleaning
- Raise snow-clearing blades over deck joints where possible
- Keep traffic off new joints until the cure time is up
Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.
What sets the cost
What shapes the price:
- Access and working height
- Whether the work must be split into stages
- Site requirements such as inductions and permits
- Specialist products, such as fire-rated or hygienic sealants
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
What to include in your enquiry
There’s no need for a formal survey. These details are enough to start:
- Drawings or a marked-up plan, if available
- Whether an asbestos survey exists
- Where the site is, with the postcode
- Access details, including height
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
