What we’re called out for in Welborne
On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.
Common reasons buildings call us in:
- Expansion joints filled with dirt and stones
- Previous reseals laid over old sealant
- Sealant peeling off one face of the joint
- Expansion joints split through the centre of the bead
Parks like Knowle Village Business Park, 0.7 miles to the west of Welborne, combine paved areas, car parks and building elevations, each with joints that move.
Questions to ask before you book
- What level of public liability insurance do they hold?
- Their plan for phasing and protecting the area
- Are they CHAS accredited or on Constructionline?
- Is the sealant right for the movement and the substrate?
How we handle expansion joint sealing in Welborne
We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it. We work on podiums and floor movement joints, cladding panel joints and precast concrete panel joints, and the failures we are asked to look at most are debris jammed in movement joints and water getting into the wall through a failed joint. Whether you call it commercial sealant work, mastic application or joint sealing, in Welborne it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Halls, schools and small commercial buildings near places like Welborne have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions we are asked in Welborne
Is Knowle Village Business Park, near Welborne, within your area?
Yes. We cover Welborne and the area around it, including industrial estates, business parks and retail parks such as Knowle Village Business Park. Send details of the unit and the work through our quote form for a quick quote.
Our building in Welborne is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
What site paperwork can you supply?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Welborne may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Finished joints are checked and backed by our 12-month guarantee.
Preparing the site
- Move anything stored against the joints
- Let building users know which areas are affected
- Confirm the product named in the specification

What else we do in Welborne
Why act early in Welborne
A torn seal left alone normally 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. Around Welborne, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
What you get with us
- Joints cleaned back to sound surfaces
- CHAS accredited
- Our applicators hold CSCS cards
- Fixed quotes based on photos, drawings or a visit

Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Changing the joint layout or spacing of a structure
- Proprietary pre-formed expansion joint systems
If you are not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Joints and surfaces we work on
- Precast concrete panel joints
- Podiums and floor movement joints
- Brickwork movement joints
- Cladding panel joints
- Car park decks and ramps
- Blockwork control joints
Maintenance after handover
To get the most from the new sealant:
- Reopen bays and walkways only after the stated cure time
- Raise snow-clearing blades over deck joints where possible
- Treat a small split as a warning, not a cosmetic issue
- Inspect exposed joints once the cold weather has passed
Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it. Regular sweeping keeps joint lines clear.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint, well after the seal first opened. Resealing promptly prevents internal damage.
