About our expansion joint sealing in Rucklers Lane
Mastic Doctor has sealed movement joints since 2005, for main contractors, FMs, managing agents and building owners. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on podiums and floor movement joints, car park decks and ramps and precast concrete panel joints, and what we are called in for most is hardened, cracked sealant on exposed facades and new sealant over old, now failing. A specialist sealant contractor works differently from a general builder: in Rucklers Lane, that means joint design, primers and backing rod as standard.
Around smaller places such as Rucklers Lane, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
Work we carry out in Hertfordshire comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email us and we’ll arrange a return visit.

FAQs: Rucklers Lane
Will you take on work at estates like Apsley Industrial Estate, close to Rucklers Lane?
Yes, sites like Apsley Industrial Estate are within our area, along with the rest of Rucklers Lane. To start, just ring 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Is Rucklers Lane off your patch?
No. Places such as Rucklers Lane are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Why do our movement joints keep failing?
It depends on how the sealant has let go: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Sometimes the edge material itself has failed.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Can you quote from photos?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
Do you guarantee expansion joint work?
Each job is backed by a 12-month guarantee on the workmanship. The guarantee covers how we sealed, not damage caused afterwards.
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Travel to remote or island sites
- Induction, permit and paperwork requirements
- The total length or number of joints
- Removal of failed or old sealant
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Details that help us quote
To price the job accurately, we need to understand the site. Useful things to include:
- Access details, including height
- When you need the work done
- The product your specification calls for
- Whether the building will be occupied during the work
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Looking after the joints
Keep the joints in good shape with a few simple steps:
- Note which joints were done, when, and with what
- Avoid parking heavy plant or pallets on joint lines
- Brief car park operatives to protect joint lines during winter clearance
- Clear dirt from joint lines during routine cleaning
On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead, and it’s worth checking joints once the cold weather has passed.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We’ll tell you which movement joints need doing now and which can wait.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building around Rucklers Lane, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take 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.
What we need from you
- Send any specification or drawings in advance
- Tell us what induction or permit system the site runs
- Make sure the joints can be reached

Floors, slabs and movement joints in Rucklers Lane
The 3 miles around Rucklers Lane take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.
Phasing is what makes joint work possible on busy sites such as Kings Park Industrial Estate (0.9 miles south-east of Rucklers Lane): one bay, aisle or car park row at a time. For a school such as Kings Langley Primary School, playground and building joints can be done in the holidays.

General trades versus a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Signs you need expansion joint sealing in Rucklers Lane
Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.
Clients typically get in touch after noticing one or more of the following:
- Spalled or broken joint edges in floors and decks
- Sealant peeling off one face of the joint
- Layers of sealant in a movement joint
- Torn sealant in brick or block movement joints
Hospitals like Hemel Hempstead Hospital (1.9 miles north of Rucklers Lane) have multi-storey or surface car parks whose joints carry vehicles round the clock.
