Questions about Old Basing
Do you take on work at healthcare sites like Basingstoke and North Hampshire Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is a smaller place like Old Basing outside your area?
Not at all. Old Basing is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Why has the sealant in our expansion joints split?
The way it has failed typically tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Broken edges are a third possibility.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you guarantee expansion joint work?
A 12-month guarantee covers our workmanship and we hold public liability insurance. Keeping joints clear of debris helps them last.
Expansion joint sealing in Old Basing
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors. We work on podiums and floor movement joints, blockwork control joints and cladding panel joints, and the failures we are asked to look at most are hardened, cracked sealant on exposed facades and sealant pulling off the joint face. Facilities teams, main contractors and managing agents in Old Basing tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Small units near places like Old Basing are often converted farm buildings with new concrete floors. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.
The 12-month guarantee is for workmanship rather than 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.

How the job changes by surface
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement with bays done in phases so the car park keeps running.
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves.
On site: what to expect
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and our waste is bagged and taken away as we go. For a job in Old Basing, the main thing is a clear picture of the work. A fixed quote follows.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Each joint is inspected and handed over with our 12-month guarantee.
What we need from you
- Make sure the joints can be reached
- Point out parking and an unloading spot
- Send asbestos survey details if the building is pre-2000

Expansion joint sealing around Old Basing: what changes locally
Old Basing is about 44 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open.
At a retail site such as The Malls, which lies west of Old Basing, trolleys, cages and cars run over floor and slab joints all day. Hospital campuses such as Basingstoke and North Hampshire Hospital, 3 miles to the west of Old Basing, grow in stages, leaving movement joints wherever new blocks meet old.

How the quote is worked out
These are the things that shape the price:
- The product specified
- Backing rod, priming and other preparation
- Whether old sealant has to be cut out first
- The total length or number of joints
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Access details, including height
- Photos of the joints, close up and from further back
- Any specification or named product
- Rough lengths or quantities, or drawings if you have them
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Do you need expansion joint sealing in Old Basing?
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Look out for the following:
- Movement joints with split or torn sealant
- Water getting into the wall through a failed joint
- Debris jammed in movement joints
- Arrises breaking up along floor joints
Schools such as Old Basing Infant School have movement joints in their walls and floors that are easy to overlook.
Questions to ask before you book
- The named product and why it was chosen
- Their public liability cover
- Whether primer will be used where the manufacturer specifies it
- Their plan for phasing and protecting the area
Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
