Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Keep scrapers and ploughs from dragging across joint sealant
- Keep stones and debris out of open joint lines
- Avoid parking heavy plant or pallets on joint lines
- Record the sealant used and the date in the O&M file
Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.
How we handle expansion joint sealing in Sewardstonebury
A movement joint only works while its seal does. Once it fails, water, grit and debris get in, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on car park decks and ramps, precast concrete panel joints and podiums and floor movement joints, and the usual reasons a site gets in touch are hardened, cracked sealant on exposed facades and rain penetration at brick or block movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Sewardstonebury it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Smaller community and commercial buildings around Sewardstonebury have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

What affects the price in Sewardstonebury
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Removal of failed or old sealant
- Joint width, depth and condition
- Location, for remote and island sites
- Whether the work must be split into stages
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

We can often quote from photos and a few details. Please tell us:

Joints that move: notes for Sewardstonebury
Sewardstonebury 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, and gritting in cold spells finds its way into open joints. Sewardstonebury is about 11 miles from central London. Warehousing clusters around the motorways that ring and radiate from London.
For estates staff at a university like University of Portsmouth Walthamstow Campus, 4.4 miles south of Sewardstonebury, building and paving joints are part of the planned maintenance list. At places like Waterways Business Centre, 1.9 miles to the north-west of Sewardstonebury, joints are sealed a section at a time so operations carry on. If you manage units on an estate such as Brimsdown Industrial Estate, 1.7 miles to the north-west of Sewardstonebury, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Movement on a scale no sealant is meant to absorb
- Leaks coming from the membrane rather than the joint seal
- Concrete or masonry repairs along the arrises
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 before you book.

FAQs: Sewardstonebury
Can you take on a job at a hospital such as The Holly Private Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is a smaller place like Sewardstonebury outside your area?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.

Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, normally low-modulus laid over backing rod at the correct depth.
Podium joints
Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix.
