About our expansion joint sealing in Thanington
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. Our applicators are CSCS-carded, we are 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. If you are dealing with joints packed with grit and debris and brittle, chalky sealant on external joints, we can put it right, whatever the surface. For commercial sealant work in Thanington, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Small units near places like Thanington are often converted farm buildings with new concrete floors. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.
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.

Traffic, movement and joints around Thanington
Central London is about 52 miles from Thanington. Warehousing clusters around the motorways that ring and radiate from London. Thanington sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
Warehouse floors on estates like Wincheap Industrial Estate, 0.7 miles north-east of Thanington, carry pallet trucks and forklifts over every saw-cut joint. For estates staff at a university like University of the Creative Arts (1.4 miles east of Thanington), building and paving joints are part of the planned maintenance list. Centres like Whitefriars Shopping Centre, 1.2 miles to the north-east of Thanington, have mall floors and service decks whose joints carry steady traffic.
Thanington is about 1 mile south-west of Wincheap, in Kent. Businesses, contractors and managing agents in Thanington can call on us for movement joints, as part of our coverage of Kent.

Questions we are asked in Thanington
Is Thanington off your patch?
No. Places such as Thanington are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Is hospital work, at somewhere like Kent and Canterbury Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Are expansion joints and movement joints the same thing?
They’re closely related. A movement joint allows for expansion, contraction, shrinkage and loading.
Do you guarantee expansion joint work?
Each job is backed by a 12-month guarantee on the workmanship. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Keeping the joints sound
Once the work is signed off, these steps help:
- Leave barriers in place until fresh joint sealant has cured
- Put movement joints on the planned maintenance inspection round
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Act on the first tear or lifting edge rather than waiting
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears. Regular sweeping keeps joint lines clear.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort. We’ll tell you which movement joints need doing now and which can wait.
On site: what to expect
At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For a site in Thanington, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- 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.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Tell us what induction or permit system the site runs
- Tell us your opening times and when work is allowed
- Share the asbestos register for older buildings

For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
- Site requirements such as inductions and permits
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Access details, including height
- Photos of the joints, close up and from further back
- The type of building and who uses it
- Rough lengths or quantities, or drawings if you have them
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
General trades versus a specialist
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.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Changing the joint layout or spacing of a structure
- Concrete or masonry repairs along the arrises
- Proprietary pre-formed expansion joint systems
If you’re not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer.
