Expansion joint sealing around Ridge: points for this area
Ridge lies roughly 15 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors. Ridge has at least three named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment.
Campuses like University of Hertfordshire (to the north of Ridge) mix old and new buildings, with movement joints wherever they meet. On industrial estates such as Borehamwood Industrial Park, 1.9 miles to the south of Ridge, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
Ridge is about 2 miles north-east of Borehamwood, in Hertfordshire. Across the EN6 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Ridge is one of 371 places in Hertfordshire on our list for movement joints. London is covered too, around 15 miles from Ridge.
Anyone looking for expansion joint sealing in EN6 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

Expansion joint sealing for commercial buildings in Ridge
If you need expansion joint sealing in Ridge, start with photographs and joint lengths. We’ll come and look where photos don’t show enough. To discuss the joints first, ring 01277 525 020 or email the details over. We work on car park decks and ramps, precast concrete panel joints and podiums and floor movement joints, and the failures we’re asked to look at most are movement joints with split or torn sealant and arrises breaking up along floor joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Ridge is the same: the right product in a properly prepared joint.
In and around smaller places like Ridge, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

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:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Changing the joint layout or spacing of a structure
- Damaged metal nosings or cover plates over a joint
If in doubt, speak to us on 01277 525 020 or email us and we will say what we think.
Surfaces we seal
- Blockwork control joints
- Precast concrete panel joints

- Brickwork movement joints
- Podiums and floor movement joints
- Car park decks and ramps
Cost factors for movement joints
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Distance, for remote addresses
- Working within restricted access windows
- Which sealant the job calls for
- How accessible the joints are
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Access details, including height
- Whether an asbestos survey exists
- Photos of the joints, close up and from further back
- Any specification or named product
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or send photos by email.

Other services in Ridge
From enquiry to sign-off
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Ridge, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- 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 flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- 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.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Let building users know which areas are affected
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use
Ask for a quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Advice
When to call us in Ridge
Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.
Things that typically lead to an enquiry:
- Damp inside where a wall movement joint has failed
- Layers of sealant in a movement joint
- Joints packed with grit and debris
- Chipped joint edges on forklift routes
Across sites such as Cranborne Industrial Estate, which lies north-east of Ridge, floor and movement joints can be sealed in phases so units keep working.
Questions to ask before you book
- How joint depth will be controlled
- What level of public liability insurance do they hold?
- Will RAMS and insurance details be available?
- Their plan for phasing and protecting the area
Questions about Ridge
Can you work on a hospital site such as Potters Bar Community Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Do you cover business parks and estates near Ridge, such as Borehamwood Industrial Park?
Yes. We cover Ridge and the area around it, including industrial estates, business parks and retail parks such as Borehamwood Industrial Park. To start, just speak to us on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Do you cover Ridge?
Yes. Ridge falls within our area, and you can call 01277 525 020 or send photos by email to get started.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
What exactly is a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint, and either way it needs a sound seal.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Treat a small split as a warning, not a cosmetic issue
- Include every elevation and deck joint in periodic inspections
- Check joints after long freezing spells
- Raise snow-clearing blades over deck joints where possible
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.
