How we handle expansion joint sealing in Haldens
We have been sealing expansion and movement joints for over 20 years, for main contractors, FMs, managing agents and building owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. If you’re dealing with layers of sealant in a movement joint and torn sealant in brick or block movement joints, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Haldens is the same: the right product in a properly prepared joint.
In a smaller place such as Haldens, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Their slabs and walls still need movement joints that work.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Different surfaces, different methods
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability.
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing and flag any joint that seems undersized.

FAQs: Haldens
Is a smaller place like Haldens outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Our unit in Welwyn Garden City is decades old: is it worth resealing the floor joints?
Usually, yes, as long as the joint edges are still sound. Resealing with the right filler or sealant for the traffic keeps grit out and protects the arrises, and we’ll tell you if the edges need repairing first.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Does the weather affect joint sealing?
Outside work depends on conditions because a damp or frozen joint won’t take a proper bond. Indoor joints can usually carry on regardless.
What exactly is a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Our process
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Work in places the size of Haldens is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Getting the site ready
- Confirm the product named in the specification
- Move anything stored against the joints
- Warn occupants and staff about the work
Getting a fixed quote
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email the details over if you’d rather talk the job through.
Related advice
Should maintenance staff do it?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Phasing around occupants
- Travel to remote or island sites
- Access and working height
- The site’s rules and procedures
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
Sending details for a quote
Diagnosis starts before we arrive. Let us know:
- The asbestos register, for older buildings
- Any dates the work must fit around
- Access details, including height
- The product your specification calls for

What else we do in Haldens
Floors, slabs and movement joints in Haldens
Haldens has two named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Haldens is in the South East, one of the UK’s drier regions. 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.
Hospital campuses such as Queen Elizabeth II Hospital, 2 miles to the south of Haldens, grow in stages, leaving movement joints wherever new blocks meet old. Campuses like University of Hertfordshire, 3.5 miles to the south of Haldens, mix old and new buildings, with movement joints wherever they meet. At places like Oldings Corner Retail Park (2.9 miles south-west of Haldens), joints are sealed a section at a time so operations carry on.
Haldens is about 1 mile north of Welwyn Garden City, in Hertfordshire. Anywhere in AL7, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 371 places in Hertfordshire. For work in that direction, see our London page, about 22 miles away.

When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Changing the joint layout or spacing of a structure
- Proprietary pre-formed expansion joint systems
If in doubt, phone 01277 525 020 or send photos by email and we’ll say what we think.
