Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Expansion joint sealing in Thorley, done properly
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1, and the bead is tooled so it grips the two faces alone. If you have hardened, cracked sealant on exposed facades and joints where the bead has lost adhesion, we can help, on brickwork movement joints, podiums and floor movement joints and precast concrete panel joints alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Thorley it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places such as Thorley, 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.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Keep scrapers and ploughs from dragging across joint sealant
- Treat a small split as a warning, not a cosmetic issue
- Note which joints were done, when, and with what
- Look over external and deck joints after a hard winter
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file, so the next reseal starts with the facts.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort, so the work can be planned rather than rushed. We can suggest an order, worst joints first.
Surface by surface
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them.
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement with bays done in phases so the car park keeps running.
Questions about Thorley
Does the sea air around Thorley change the choice of 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 Thorley off your patch?
Not at all: smaller places are covered as well as 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.
What causes movement joint sealant to fail?
Normally the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing so the same failure isn’t repeated.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Warehouse floors and decks around Thorley
Thorley sits close to the coast, within about 2 miles. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, which is why split joints are worth sealing before the edges deteriorate. Thorley sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.
In and around Thorley, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Common problems we fix in Thorley
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’s common on joints sealed in a hurry.
Most enquiries start with something like this:
- Debris jammed in movement joints
- Water dripping through deck or ramp joints
- Brittle, chalky sealant on external joints
- Chipped joint edges on forklift routes
Sites like Lymington New Forest Hospital, 5.9 miles north-west of Thorley, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Thorley are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site
- Point out parking and an unloading spot
- Share your working hours and any access restrictions
- Have the specification and drawings to hand

Why deal with it now?
Some quotes just add sealant over the old bead. A bead over the old seal can’t bond or flex, so it fails quickly. Full removal and preparation is in every quote. Converted and older buildings near places like Thorley tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
