Great Hallingbury: questions and answers
Do you cover business parks and estates near Great Hallingbury, such as The Links Business Centre?
Yes. Estates, retail parks and business parks around Great Hallingbury, The Links Business Centre among them, are all within reach. A few photographs and the unit address let us price the work.
Do you take on work at healthcare sites like Herts And Essex Community Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Which product is best for expansion joints?
We choose a sealant with a movement capability that suits the joint, classified under BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

What we’re called out for in Great Hallingbury
Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons, and it’s common on joints sealed in a hurry.
Site and facilities staff are often the first to spot these:
- Sealant pulling off the joint face
- Expansion joints filled with dirt and stones
- Brittle, chalky sealant on external joints
- Car park joints leaking onto vehicles below
For buildings at a park such as The Links Business Centre (1.2 miles north-west of Great Hallingbury), brick and panel movement joints are easy to forget until one leaks.
Questions to ask before you book
- Their plan for phasing and protecting the area
- Who will actually carry out the work
- Their pre-qualification and accreditations
- Will failed sealant be removed rather than covered?
After the work
For the best life from the joints:
- Clear dirt from joint lines during routine cleaning
- Reopen bays and walkways only after the stated cure time
- Keep product details with the building records for the next reseal
- Keep racking legs and heavy point loads off floor joints
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth and we will tell you when each bay or area can reopen. Keeping the area coned off until then avoids tyre marks and damage.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.

What else we do in Great Hallingbury
How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and we clear our waste as we work. Rural sites near Great Hallingbury may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
Before we start on site

Why deal with it now?
Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Older rural buildings around Great Hallingbury move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
