FAQs: Ashton
Can you work on a hospital site such as Moorgreen Hospital?
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.
Do you cover business parks and estates near Ashton, such as Swanmore Business Park?
Yes. Estates, retail parks and business parks around Ashton, Swanmore Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What causes movement joint sealant to fail?
Usually the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing, rather than replacing like for like.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Expansion joint sealing in Ashton
Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. We work on cladding panel joints, podiums and floor movement joints and precast concrete panel joints, and the failures we’re asked to look at most are water getting into the wall through a failed joint and joints where the bead has lost adhesion. A single leaking joint is often how a building in Ashton first comes to us: we look at the rest while we’re there and tell you what we find.
Around smaller places such as Ashton, 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.

The price varies from site to site. It mainly depends on:

Do you need expansion joint sealing in Ashton?
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.
It’s worth sending us details if you spot any of the following:
- Spalled or broken joint edges in floors and decks
- Water getting into the wall through a failed joint
- Previous reseals laid over old sealant
- Sealant peeling off one face of the joint
Another example is Waltham Business Park (2.7 miles south-east of Ashton), where floors and yards would be done in stages around the occupiers.

After the work
Problems stay small when the joints are checked regularly. Specifically:
- Include every elevation and deck joint in periodic inspections
- Reopen bays and walkways only after the stated cure time
- Brief car park operatives to protect joint lines during winter clearance
- Keep product details with the building records for the next reseal
Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check and long before edges start to break. Should you spot a problem, you can call 01277 525 020 or use the quote form and send a picture.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.
How a job runs
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Ashton are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- 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.
Before we start on site
- Point out parking and an unloading spot
- Warn occupants and staff about the work
- Have the specification and drawings to hand

What happens if it’s left?
Resealing is typically the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we will tell you they need repairing first. Converted and older buildings near places like Ashton tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Should maintenance staff do it?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
