Expansion joint sealing across Chelmsford
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price 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)
- Waterproofing layers buried beneath the sealant
- Joints too narrow for the movement, which need redesigning by the engineer
If in doubt, phone 01277 525 020 or use the quote form and we will say what we think.
Surfaces we seal
- Cladding panel joints
- Precast concrete panel joints
- Podiums and floor movement joints
- Brickwork movement joints
- Blockwork control joints
- Car park decks and ramps
Expansion joint sealing in Chelmsford, done properly
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. We work on car park decks and ramps, precast concrete panel joints and blockwork control joints, and what we’re called in for most is chipped joint edges on forklift routes and torn sealant in brick or block movement joints. One point of contact handles commercial sealant work in Chelmsford from the first photographs to the final walk-round, whether it’s one building or several.
Industrial estates, retail parks and multi-storey car parks are typical of a place the size of Chelmsford. Their floor joints take forklifts, pallet trucks and cars every day, and the right filler or sealant depends on the traffic and the movement.
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.
What we are called out for in Chelmsford
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.
Common reasons buildings call us in:
- Water dripping through deck or ramp joints
- Chipped joint edges on forklift routes
- Movement joints with split or torn sealant
- Sealant peeling off one face of the joint
Retail sites such as Riverside Retail Park, under half a mile west of Chelmsford, have car park, service yard and shop floor joints under constant traffic.
Questions to ask before you book
- What the guarantee covers, and for how long
- Their approach to joint depth and backing
- Whether old or failed sealant will be cut out, not overlaid
- Do they follow the manufacturer’s priming guidance?
Slabs, ramps and loading bays in Chelmsford
At about 30 miles from central London, Chelmsford is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift. Chelmsford is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.
Hospital campuses such as Priory Hospital Chelmsford (to the north of Chelmsford) grow in stages, leaving movement joints wherever new blocks meet old. For estates staff at a university like Anglia Ruskin University, 0.6 miles to the north-west of Chelmsford, building and paving joints are part of the planned maintenance list.

For managing agents and facilities managers

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Chelmsford. One quote can cover more than one site, which keeps the paperwork simple.
Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and our waste is bagged and taken away as we go. Town-centre jobs in Chelmsford can mean limited parking and loading, whereas edge-of-town units normally have yard space. Either way, tell us what’s available.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Warn occupants and staff about the work
- Share the asbestos register for older buildings
- Tell us your opening times and when work is allowed
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Chelmsford: questions and answers
Is hospital work, at somewhere like Priory Hospital Chelmsford, something you do?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work at a site such as Riverside Retail Park, by Chelmsford?
Yes. Our area takes in Chelmsford and its surroundings, with estates and business parks such as Riverside Retail Park included. Photos and a short description are enough for a first look.
Why has the sealant in our expansion joints split?
It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Can you seal joints in cold or wet weather?
A wet joint can’t be sealed properly. The work is simply moved to the next suitable day.
Leave it or put it right?
Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open, compared with a full closure. We agree phasing with you before work starts. Water getting in through a failed joint can damage finishes, stock and fittings. It pays to act early.
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

What affects the price in Chelmsford
The price varies from site to site. Expect it to depend on:
- Whether the work must be split into stages
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
A few photos plus some basic facts will normally do. It helps to include:
- Specification clauses that apply
- A wide shot and a close-up of the area
- Asbestos survey details if the building is older
- Where the site is, with the postcode
