Expansion joint sealing in Lissenden Gardens: the local picture
Lissenden Gardens 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. London car parks, loading bays and podium decks often can’t close for long, so we seal in sections and hand areas back as each cures.
Campuses like American University in London, 1.5 miles east of Lissenden Gardens, mix old and new buildings, with movement joints wherever they meet. Office parks like Regis Road Business Park (to the south-east of Lissenden Gardens) have decks, ramps and clad elevations whose joints take movement every day. A healthcare site such as Royal Free Hospital (to the west of Lissenden Gardens) depends on car parks, ramps and service yards whose joints take traffic all day.

Expansion joint sealing for commercial buildings in Lissenden Gardens
We’ve 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. Each job is backed by a 12-month guarantee on the workmanship. We work on blockwork control joints, precast concrete panel joints and cladding panel joints, and what we are called in for most is damp inside where a wall movement joint has failed and car park joints leaking onto vehicles below. For commercial sealant work in Lissenden Gardens, you deal with one contact from quote to sign-off, whether it’s one building or several.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. When a joint fails, grit and water get in and the arrises start to break up, so it pays to act early.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Our process
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. In Lissenden Gardens, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First, the joints are inspected for width, movement and the type of failure.
- Next, we fix a price and confirm the sealant we propose for the movement.
- The failed seal is removed and both faces are cleaned until sound and dry.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
- Tell us which areas need to stay in use
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

How the quote is worked out
A fixed quote reflects the actual work. It takes account of:
- Phasing around occupants
- How much there is to seal
- Removal of failed or old sealant
- The product specified
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
What we need to price the job
To price the job accurately, we need to understand the site. Send us:
- How the joints are reached, and at what height
- The type of building and who uses it
- Drawings or a marked-up plan, if available
- Specification clauses that apply
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email drawings and photos with what you know.
Different surfaces, different methods
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond and check the edges for soundness as we go.

Will you come and look before quoting?

How long does movement joint sealing take?

Maintenance after handover
Once the work is signed off, these steps help:
- Report split or peeling joint sealant early
- Clear dirt from joint lines during routine cleaning
- Keep traffic off new joints until the cure time is up
- Put movement joints on the planned maintenance inspection round
Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort so you can prioritise and budget. We’ll tell you which movement joints need doing now and which can wait.
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Why it’s worth doing now in Lissenden Gardens
A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach, and we will say so before quoting. Getting scaffold, permits or access booked in Lissenden Gardens takes effort, so it makes sense to deal with every failing joint while access is in place.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
