Expansion joint sealing for commercial buildings in South Stour
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors on sites in South Stour. We work on cladding panel joints, brickwork movement joints and precast concrete panel joints, and what we’re called in for most is rain penetration at brick or block movement joints and car park joints leaking onto vehicles below. Facilities teams, main contractors and managing agents in South Stour tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In and around smaller places like South Stour, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Inspect movement joints alongside other routine building checks
- Keep traffic off new joints until the cure time is up
- Keep scrapers and ploughs from dragging across joint sealant
- Inspect exposed joints once the cold weather has passed
Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records so future maintenance isn’t guesswork.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors by which time the joint has been open for a while. Resealing promptly prevents internal damage.
What we can’t put right
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Concrete or masonry repairs along the arrises
- A joint that has to be widened or re-detailed before it can work
- Damaged metal nosings or cover plates over a joint
Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

FAQs: South Stour
Can you take on a job at a hospital such as William Harvey Hospital (Ashford)?
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.
Is a smaller place like South Stour outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Can you send site paperwork?

Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Can staff carry on working while you’re here?
Typically, yes. We phase the work so most of the building stays in use.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What we are called out for in South Stour
Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.
Clients typically get in touch after noticing one or more of the following:
- Sealant pulling off the joint face
- Expansion joints filled with dirt and stones
- Arrises breaking up along floor joints
- Rain penetration at brick or block movement joints
Hospital campuses such as William Harvey Hospital (Ashford) (2.4 miles north of South Stour) grow in stages, leaving movement joints wherever new blocks meet old.
Questions to ask before you book
- Whether their applicators hold CSCS cards
- How the existing material will be dealt with
- How joint depth will be controlled
- The terms of the workmanship guarantee
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For work around South Stour, 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.
- 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.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Warn occupants and staff about the work
- Explain the parking and delivery arrangements
Getting a fixed quote
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or speak to us on 01277 525 020 or email a schedule or drawings to discuss it first.

Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.
