Expansion joint sealing for commercial buildings in Bernards Heath
The seal is what lets a movement joint do its job. When the sealant splits or lets go, the gap fills with dirt and water, 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. If you have new sealant over old, now failing and car park joints leaking onto vehicles below, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Bernards Heath is the same: the right product in a properly prepared joint.
In a smaller place such as Bernards Heath, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Concrete floors and yards in these buildings move and crack like any others.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What sets the cost
What shapes the price:
- Working within restricted access windows
- Location, for remote and island sites
- How accessible the joints are
- Site requirements such as inductions and permits
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
However big the job, the same details help:
- Any specification or named product
- The postcode of the building
- What the building is and how it’s used
- When you need the work done
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. Work in places the size of Bernards Heath is planned as a single visit where we can. Clear photos and measurements help us bring the right products.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site
- Point out parking and an unloading spot
- Tell staff and tenants when we’ll be in
- Agree which areas must stay open

Advice
When to call us in Bernards Heath
When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons.
Any of the following is a good reason to get the joints checked over:
- Car park joints leaking onto vehicles below
- Chipped joint edges on forklift routes
- Weathered movement joint sealant that no longer flexes
- Damp inside where a wall movement joint has failed
For a centre such as Village Arcade St Albans, which lies south-west of Bernards Heath, the service yard and car park joints typically need attention first.
Questions to ask before you book
- What the guarantee covers, and for how long
- Their approach to joint depth and backing
- Their plan for phasing and protecting the area
- Do they follow the manufacturer’s priming guidance?
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Cracking or settlement that calls for an engineer’s assessment
- 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 us and we will tell you honestly.

Owners, agents and contractors
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
How the job changes by surface
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. The product must bond to both substrates and cope with the movement, with primer where specified.

Common questions from Bernards Heath clients
Would you work within a site like St Albans City Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Bernards Heath off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
What sealant do you use in movement joints?
Movement capability matters most. Hybrid or MS polymer products suit some mixed-material joints.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
What timescale should we allow for resealing expansion joints?
The metres of joint, the access and the amount of removal decide it. Typically it takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access.
What will the job cost?
We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.
Is movement joint sealing guaranteed?
Each job is backed by a 12-month guarantee on the workmanship. The guarantee covers how we sealed, not damage caused afterwards.
