Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Keep scrapers and ploughs from dragging across joint sealant
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Reopen bays and walkways only after the stated cure time
- Treat a small split as a warning, not a cosmetic issue
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. If anything looks wrong, speak to us on 01277 525 020 or use the quote form with photographs.
Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load. Keeping the seal sound avoids all of that.
Expansion joint sealing in Hundridge
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on blockwork control joints, precast concrete panel joints and cladding panel joints, and the usual reasons a site gets in touch are movement joints with split or torn sealant and sealant pulling off the joint face. For commercial sealant work in Hundridge, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around smaller places such as Hundridge, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What else we do in Hundridge
Why it’s worth doing now in Hundridge
A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Acting at the first split keeps the cost down. One visit to deal with every failing joint makes more sense than several trips to a place like Hundridge. Send photos of each area and we will quote for the lot.
A quote for movement joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.
Why appoint us
- Colours chosen to suit frames, cladding or finishes where possible
- Old sealant cut out, never sealed over
- Work to your specification and the manufacturer’s guidance
- One phone line for London, the South East and Scotland

Commercial clients in Hundridge
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Hundridge are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Preparing the site
- Tell us which areas need to stay in use
- Send your site hours and access windows
- Send asbestos survey details if the building is pre-2000

Your questions answered
Is hospital work, at somewhere like The Chiltern Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Will you take on work at estates like Waterside Business Park, close to Hundridge?
Yes, sites like Waterside Business Park are within our area, along with the rest of Hundridge. Send details of the unit and the work through our quote form for a quick quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Why do our movement joints keep failing?
Usually the joint is moving more than the sealant can take. That’s why we check width, depth and movement class before quoting so the same failure isn’t repeated.
Do you use silicone or polyurethane in movement joints?
It depends on the movement, exposure and traffic. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints, and the specification has the final say.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can a joint be sealed if the edges are broken?
A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.
Where floor joints take the most wear near Hundridge
Rainfall across the South East, Hundridge included, is lower than in many parts of the UK. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in. Hundridge lies roughly 28 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.
Parks like Waterside Business Park (to the east of Hundridge) combine paved areas, car parks and building elevations, each with joints that move. A campus such as Buckinghamshire New University (1.7 miles south of Hundridge) has long runs of movement joint in its buildings, decks and paving.

Signs you need expansion joint sealing in Hundridge
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.
Site and facilities staff are often the first to spot these:
- Brittle, chalky sealant on external joints
- Layers of sealant in a movement joint
- Leaks through car park deck joints onto the level below
- Water getting into the wall through a failed joint
Schools such as Hyde Heath Infant School have movement joints in their walls and floors that are easy to overlook.
Questions to ask before you book
- Whether their applicators hold CSCS cards
- How the joint faces will be prepared and primed
- How they’ll work around occupants
- How joint depth will be controlled
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)
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Joints too narrow for the movement, which need redesigning by the engineer
