About our expansion joint sealing in Alderholt
Mastic Doctor has sealed movement joints since 2005. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. If you are dealing with weathered movement joint sealant that no longer flexes and torn sealant in brick or block movement joints, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Alderholt it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around places the size of Alderholt, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep racking legs and heavy point loads off floor joints
- Look over external and deck joints after a hard winter
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Treat a small split as a warning, not a cosmetic issue
Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster. Keeping the filler or sealant sound protects the floor.
Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Leaks coming from the membrane rather than the joint seal
- Changing the joint layout or spacing of a structure
If you’re not sure, just ring 01277 525 020 or send photos by email and we will give you a straight answer before you book.

Alderholt: questions and answers
Is a smaller place like Alderholt outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Is Fordingbridge Business Park, near Alderholt, within your area?
Yes. Our area takes in Alderholt and its surroundings, with estates and business parks such as Fordingbridge Business Park included. A few photos and the unit address let us price the work.
What happens if it rains on the day?
The joint has to be dry, and the air and surface temperature inside the product’s limits. Frost, rain and condensation on steel or concrete can hold up external work.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
Do you use silicone or polyurethane in movement joints?
It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks typically need a polyurethane unless the specification names something else.
What timescale should we allow for resealing expansion joints?
Allow a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Timings are set out in the quote along with the phasing plan.
What we are called out for in Alderholt
Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.
These are often picked up first by site or facilities staff:
- Expansion joints split through the centre of the bead
- Spalled or broken joint edges in floors and decks
- Leaks through car park deck joints onto the level below
- Weathered movement joint sealant that no longer flexes
Another example is Sandleheath Industrial Estate, 1.6 miles to the north of Alderholt, where floors and yards would be done in stages around the occupiers.
What to look for in a quote
- Can the work be phased to keep areas open?
- Whether old or failed sealant will be cut out, not overlaid
- Will RAMS and insurance details be available?
- How long is the guarantee, and what does it include?
Different surfaces, different methods
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, normally low-modulus laid over backing rod at the correct depth.
Joints between different materials
Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement.
Our process
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Several jobs near Alderholt can be grouped on one trip. Tell us your site hours and we’ll plan around them.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Before we start on site
- Have the specification and drawings to hand
- Make sure the joints can be reached
- Flag any permit to work we’ll need

Slabs, ramps and loading bays in Alderholt
The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. At least three named trading, business or retail sites lie within about 3 miles of Alderholt. Their warehouses, yards and car parks are exactly where joints take the most punishment.
For buildings at a park such as Fordingbridge Business Park, which lies north-east of Alderholt, brick and panel movement joints are easy to forget until one leaks. Hospital campuses such as Fordingbridge Hospital (to the north-east of Alderholt) grow in stages, leaving movement joints wherever new blocks meet old.
