Expansion joint sealing for commercial buildings in Chignall Smealy
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors for buildings in Chignall Smealy. If you have spalled or broken joint edges in floors and decks and expansion joints split through the centre of the bead, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Chignall Smealy is the same: the right product in a properly prepared joint.
Jobs around smaller places like Chignall Smealy are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

For managing agents and facilities managers
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Concrete or masonry repairs along the arrises
- Waterproofing layers buried beneath the sealant
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think.

Common questions from Chignall Smealy clients
Will our site in Chignall Smealy 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. We agree the sequence and timings with you before we start.
Do you take on work at healthcare sites like Broomfield Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
What timescale should we allow for resealing expansion joints?
Expect a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints and phased work can stretch that to suit your site. Cure time before reopening is confirmed on the day.
When to call us in Chignall Smealy
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes, and it’s common on joints sealed in a hurry.
These are often picked up first by site or facilities staff:
- Leaks through car park deck joints onto the level below
- Sealant peeling off one face of the joint
- Arrises breaking up along floor joints
- Expansion joints filled with dirt and stones
For estates staff at a university like Anglia Ruskin University, 2.9 miles to the south of Chignall Smealy, building and paving joints are part of the planned maintenance list.
Before you book anyone
- Who will actually carry out the work
- How the existing material will be dealt with
- How the joint faces will be prepared and primed
- What level of public liability insurance do they hold?
Looking after the joints
After handover, these steps help:
- Note which joints were done, when, and with what
- Reopen bays and walkways only after the stated cure time
- Treat a small split as a warning, not a cosmetic issue
- Keep scrapers and ploughs from dragging across joint sealant
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.
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 can suggest an order, worst joints first.
Our process
Occupied buildings need a little choreography. We sign and contain the area we’re 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 Chignall Smealy, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Getting the site ready
- Send your site hours and access windows
- Let us know about inductions and permits
- Point out parking and an unloading spot

What the job involves on each surface
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement, and tell you if edges need repairing first.
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen, and we’ll confirm the colours available for the specified product.
Warehouse floors and decks around Chignall Smealy
At about 29 miles from central London, Chignall Smealy is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.
For a school such as Newlands Spring Primary School, playground and building joints can be done in the holidays. For an estate such as Broomfield Hospital, 2 miles to the east of Chignall Smealy, the joints in ramps, decks and long building elevations all need attention over time.
