From enquiry to sign-off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off.

- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.

Expansion joint sealing for commercial buildings in Alkham
The seal is what lets a movement joint do its job. When the sealant splits or lets go, the gap fills with dirt and water. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you have leaks through car park deck joints onto the level below and sealant peeling off one face of the joint, we can help, whatever the surface. Searching for sealant specialists in Alkham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Around smaller places such as Alkham, 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.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Slabs, ramps and loading bays in Alkham
Alkham is within about 3 miles of the coast. Open joints in coastal car parks and yards let in salt-laden water as well as grit, and edges left open tend to break up faster. Alkham is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, while winter salting gets into any joint left open.
Sites like Buckland Hospital (to the east of Alkham) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
Alkham is about 3 miles west of Dover, in Kent. We cover commercial sites throughout Alkham, whether it’s a single job or part of a planned programme. We work across 931 places in Kent. We also cover London, some 62 miles away.

Your questions answered
Our building in Alkham is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Is Alkham too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
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 one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
When something else is needed
Being straight saves everyone time. New sealant won’t cure:
- Proprietary pre-formed expansion joint systems
- Joints too narrow for the movement, which need redesigning by the engineer
- Concrete or masonry repairs along the arrises
If in doubt, ring 01277 525 020 or email the details over and we will say what we think.
Joints and surfaces we work on
- Cladding panel joints
- Brickwork movement joints
- Precast concrete panel joints
- Car park decks and ramps
- Blockwork control joints
- Podiums and floor movement joints
Keeping the joints sound
A few simple habits keep the new joints working:
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Look over external and deck joints after a hard winter
- Keep product details with the building records for the next reseal
- Treat a small split as a warning, not a cosmetic issue
Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints.
An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall, turning a sealant job into a repair job. A sound seal keeps the joint working.
When to call us in Alkham
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.
Site and facilities staff are often the first to spot these:
- Car park joints leaking onto vehicles below
- Expansion joints split through the centre of the bead
- Arrises breaking up along floor joints
- Rain penetration at brick or block movement joints
University campuses such as University Centre Folkestone, 4.1 miles south-west of Alkham, have car parks, paved walkways and building elevations with movement joints.

What happens if it’s left?
Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s normally not far behind. Where it helps, we quote both options. Older rural buildings around Alkham move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
