Expansion joint sealing for commercial buildings in Hardwick
Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. We work on podiums and floor movement joints, blockwork control joints and car park decks and ramps, and the failures we’re asked to look at most are previous reseals laid over old sealant and torn sealant in brick or block movement joints. A single leaking joint is often how a building in Hardwick first comes to us: we look at the rest while we are there and tell you what we find.
In and around smaller places like Hardwick, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
A short, simple internal joint is often within reach of a maintenance team. 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.
How the job changes by surface
Brickwork and blockwork joints
Vertical movement joints in brick and block walls let the masonry grow and shrink. They take a low-modulus sealant with a movement class to suit.
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.
Traffic, movement and joints around Hardwick
Hardwick is about 61 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day. Hardwick has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Hospital campuses such as Witney Community Hospital, 3 miles to the north-west of Hardwick, grow in stages, leaving movement joints wherever new blocks meet old. Campuses like University of Oxford, 3.6 miles to the south of Hardwick, mix old and new buildings, with movement joints wherever they meet.

Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and we clear our waste as we work. For a building around Hardwick, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- Photos, joint lengths and drawings come to us, or we visit.
- 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.
- Any broken arrises or friable edges are flagged before work goes further.
- 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.
Before we start on site
- Point out parking and an unloading spot
- Share your working hours and any access restrictions
- Clear stock, furniture or equipment away from the joints

FAQs: Hardwick
Is Hardwick off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Will you take on work at estates like Lakeside Industrial Estate, close to Hardwick?
Yes. We cover Hardwick and the area around it, including industrial estates, business parks and retail parks such as Lakeside Industrial Estate. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.
Is movement joint sealing guaranteed?
Each job is backed by a 12-month guarantee on the workmanship. The guarantee covers how we sealed, not damage caused afterwards.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it.
Are expansion joints and movement joints the same thing?
They’re closely related. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Leave it or put it right?
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use without shutting the whole car park. We agree phasing with you before work starts. Halls, stores and units around places like Hardwick may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Do you need expansion joint sealing in Hardwick?
Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant. A sealant that isn’t trafficable won’t last there.
Most enquiries start with something like this:
- Car park joints leaking onto vehicles below
- Expansion joints filled with dirt and stones
- Damp inside where a wall movement joint has failed
- New sealant over old, now failing
Another example is Wessex Industrial Estate (2.2 miles north-west of Hardwick), where floors and yards would be done in stages around the occupiers.
