About our expansion joint sealing in Out Elmstead
Mastic Doctor has sealed movement joints since 2005. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on podiums and floor movement joints, precast concrete panel joints and cladding panel joints, and what we’re called in for most is joints packed with grit and debris and sealant pulling off the joint face. Whether you call it commercial sealant work, mastic application or joint sealing, in Out Elmstead it comes down to the same thing: the right product in a properly prepared joint.
Halls, schools and small commercial buildings near places like Out Elmstead have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Floors, slabs and movement joints in Out Elmstead
Out Elmstead is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint. Out Elmstead lies roughly 57 miles out from central London. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift.
Large sites such as Kent and Canterbury Hospital, 4.6 miles north-west of Out Elmstead, have car parks, service roads and long elevations with movement joints in brick and panels. Business parks such as CT3 Business Park (to the east of Out Elmstead) have car parks, paved areas and long brick and panel elevations, all with movement joints.
Out Elmstead is about 5 miles south-east of Canterbury, in Kent.

Signs you need expansion joint sealing in Out Elmstead
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.
It’s worth sending us details if you spot any of the following:
- Expansion joints filled with dirt and stones
- Torn sealant in brick or block movement joints
- Brittle, chalky sealant on external joints
- Water dripping through deck or ramp joints
Schools such as Barham Church of England Primary School have movement joints in their walls and floors that are easy to overlook.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- What site paperwork they can supply
- How the existing material will be dealt with
- Their approach to joint depth and backing
Questions we are asked in Out Elmstead
Would you work within a site like Kent and Canterbury Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work at a site such as CT3 Business Park, by Out Elmstead?
Yes. Estates, retail parks and business parks around Out Elmstead, CT3 Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is movement joint sealing guaranteed?
A 12-month guarantee covers our workmanship. Regular sweeping and inspection help the joints last.
What will the job cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Do you offer coloured sealant?
It depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Leave it or put it right?
Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. Full removal and preparation is in every quote. Older rural buildings around Out Elmstead move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Why appoint us

- Fully insured, including public liability cover
- Workmanship guaranteed for 12 months

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- A joint that has to be widened or re-detailed before it can work
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think.
What we seal
- Brickwork movement joints
- Podiums and floor movement joints

How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Out Elmstead can be grouped with others nearby. A fixed quote is given before anything starts.
- We look at the joints, their width and how they’ve failed.
- Next, we fix a price and confirm the sealant we propose for the movement.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Preparing the site
- Tell us your opening times and when work is allowed
- For older buildings, check the asbestos register before work
- Let building users know which areas are affected
