How we handle expansion joint sealing in Mill Hill
Mastic Doctor has sealed movement joints since 2005. 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 precast concrete panel joints, brickwork movement joints and car park decks and ramps, and the failures we are asked to look at most are spalled or broken joint edges in floors and decks and weathered movement joint sealant that no longer flexes. Facilities teams, main contractors and managing agents in Mill Hill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around Mill Hill, most floor and movement joint jobs are single buildings or yards, so we gather photos and measurements first. That way the right materials come on the day and the job is done in one visit where possible.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Commercial clients in Mill Hill
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Mill Hill can form part of a wider programme across Kent.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
What happens if it’s left?
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now. We can split the scope into urgent and planned. In a smaller place such as Mill Hill, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.
Why us?
- CHAS accredited
- Products installed to the manufacturer’s instructions
- Fixed quotes based on photographs, drawings or a visit

Mill Hill is within about 2 miles of the coast. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, and edges left open tend to break up faster. At about 67 miles from central London, Mill Hill is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day.
Schools such as St Mary's Catholic Primary School have movement joints in their walls and floors that are easy to overlook.

Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Our process
Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Several jobs near Mill Hill can be grouped on one trip. Tell us your site hours and we will plan around them.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- 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.
- Old sealant and debris are cut out of every joint.
- 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.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Flag any permit to work we’ll need
- Let building users know which areas are affected
- Arrange parking or a loading space

Advice
How the job changes by surface
Podium joints
Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix and flag it if the membrane looks like the source.
Car park decks and ramps
Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed flagging broken edges along the way.
Questions we’re asked in Mill Hill
Is hospital work, at somewhere like Victoria Hospital, something you do?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is a smaller place like Mill Hill outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Can you seal car park deck joints?
Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
What if the joint edges are damaged?
Broken arrises have to be put right before resealing. Sealing over them leads to early failure.
Common problems we fix in Mill Hill
Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.
Any of the following is a good reason to get the joints checked over:
- Car park joints leaking onto vehicles below
- Joints where the bead has lost adhesion
- Movement joints with split or torn sealant
- Damp inside where a wall movement joint has failed
Hospitals like Victoria Hospital (to the north-east of Mill Hill) have multi-storey or surface car parks whose joints carry vehicles round the clock.
