On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Rural sites near Roe Green may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- We start with photographs, 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.
Getting the site ready
- Explain the parking and delivery arrangements
- Send asbestos survey details if the building is pre-2000
- Send any specification or drawings in advance

Advice
Expansion joint sealing for commercial buildings in Roe Green
Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. If you are dealing with movement joints with split or torn sealant and brittle, chalky sealant on external joints, we can help, whatever the surface. A single leaking joint is often how a building in Roe Green first comes to us: we look at the rest while we’re there and tell you what we find.
In and around smaller places like Roe Green, 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.
Work we carry out in Hertfordshire comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or send photos by email and we will arrange a return visit.

After the work
A few simple habits keep the new joints working:
- Clear dirt from joint lines during routine cleaning
- Put movement joints on the planned maintenance inspection round
- Note which joints were done, when, and with what
- Act on the first tear or lifting edge rather than waiting
Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. That water often carries de-icing salts with it and it can affect the structure over time. Sealing the joint promptly stops it at source.

Roe Green: questions and answers
Do you cover business parks and estates near Roe Green, such as Honeywood Industrial Centre?
Yes. Our area takes in Roe Green and its surroundings, with estates and business parks such as Honeywood Industrial Centre included. To start, just phone 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Will our site in Roe Green have to close for joint sealing?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.
Can you seal joints in cold or wet weather?
Outside work depends on conditions. Indoor joints can usually carry on regardless.
Can you work on car park ramps and decks?
Yes. Let us know the opening hours and which levels or bays have to stay available.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Joints that move: notes for Roe Green
Roe Green is about 34 miles from central London. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day. Roe Green sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.
For an occupier at a site such as Honeywood Industrial Centre (2.6 miles south of Roe Green), the joints at loading doors and dock levellers usually see the hardest wear.

When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If you’re not sure, just ring 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

Why deal with it now?
Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex, so it fails quickly. Full removal and preparation is in every quote. Around Roe Green, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
A quote for movement joints depends on quantities, condition and access, and any specification that applies. Call for a quote.
