Expansion joint sealing in Dagenham
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Expansion joint sealing in Dagenham, done properly
For movement joints in Dagenham, photos and approximate lengths are the best start. We’ll come and look where photographs don’t show enough before issuing a fixed quote. To discuss the joints first, give us a call on 01277 525 020 or email a schedule or drawings. If you have damp inside where a wall movement joint has failed and weathered movement joint sealant that no longer flexes, we can put it right, whatever the surface. Most enquiries from Dagenham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. A failed joint lets water and debris in, and the edges soon spall.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Changing the joint layout or spacing of a structure
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Cracking or settlement that calls for an engineer’s assessment
If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
What we seal
- Podiums and floor movement joints

What the job involves on each surface
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves.

Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. All of Greater London is in the ULEZ, and kerbside space in Dagenham can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Explain the parking and delivery arrangements
- Send asbestos survey details if the building is pre-2000
- Send your site hours and access windows

Related advice
When to call us in Dagenham
Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.
Any of the following is a good reason to get the joints checked over:
- Brittle, chalky sealant on external joints
- Arrises breaking up along floor joints
- Water dripping through deck or ramp joints
- Previous reseals laid over old sealant
At a retail site such as Merrielands Retail Park, which lies south-west of Dagenham, joints in car parks, service yards and sales floors carry cars, cages and trolleys every day.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Which product they’ll use, and why it suits the joint
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Can the work be phased to keep areas open?
Your questions answered
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
Do you cover business parks and estates near Dagenham, such as Merrielands Retail Park?
Yes. We cover Dagenham and the area around it, including industrial estates, business parks and retail parks such as Merrielands Retail Park. Photos and a short description are enough for a first look.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
What happens if it rains on the day?
The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside so external dates keep some flexibility.
Why act early in Dagenham
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. We will flag where edges need repair before sealing. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Where floor joints take the most wear near Dagenham
Few London car parks or loading bays can be taken out of use for more than a short spell, so joints are sealed in sections with each area handed back once cured. Dagenham has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.
Sites like Grays Court Community Hospital (to the south-west of Dagenham) carry ambulances, deliveries and visitors’ cars over their road and deck joints. For a school such as Village Infants' School, playground and building joints can be done in the holidays.
