How we handle expansion joint sealing in Founthill
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 seal across each one keeps out water and grit. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Founthill. We work on precast concrete panel joints, brickwork movement joints and car park decks and ramps, and the failures we are asked to look at most are expansion joints split through the centre of the bead and chipped joint edges on forklift routes. Most enquiries from Founthill start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Smaller community and commercial buildings around Founthill have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

What the job involves on each surface
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability, and we’ll confirm the colours available for the specified product.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal.
Traffic, movement and joints around Founthill
Founthill sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. At about 37 miles from central London, Founthill is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds.
Phasing is what makes joint work possible on busy sites such as Bellbrook Enterprise Centre (2.9 miles east of Founthill): one bay, aisle or car park row at a time. Hospitals like Uckfield Community Hospital (to the east of Founthill) have multi-storey or surface car parks whose joints carry vehicles round the clock.
Founthill is about 3 miles west of Uckfield, in East Sussex. We cover commercial sites throughout Founthill. Founthill is one of 308 places in East Sussex on our list. There’s a separate page for Brighton, about 11 miles away.

Questions about Founthill
Is Founthill off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Is a hospital such as Uckfield Community Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Can the building stay open while you work?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Proprietary pre-formed expansion joint systems
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think.
Joints and surfaces we work on
- Precast concrete panel joints
- Blockwork control joints

Our process
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If others near Founthill need work, visits can be combined. A fixed quote is given before anything starts.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
What we need from you
- Let us know about inductions and permits
- Have the specification and drawings to hand
- Move anything stored against the joints

Related advice
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.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Signs you need expansion joint sealing in Founthill
Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears.
Any of the following is a good reason to get the joints checked over:
- Spalled or broken joint edges in floors and decks
- Joints where the bead has lost adhesion
- Layers of sealant in a movement joint
- Damp inside where a wall movement joint has failed
On industrial estates such as Bellbrook Industrial Estate, 2.8 miles east of Founthill, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
