For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Expansion joint sealing in Stone Hill
Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. We work on brickwork movement joints, car park decks and ramps and podiums and floor movement joints, and the failures we are asked to look at most are movement joints with split or torn sealant and weathered movement joint sealant that no longer flexes. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Stone Hill is the same: the right product in a properly prepared joint.
In and around smaller places like Stone Hill, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. If others near Stone Hill need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- 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.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Finished joints are checked and backed by our 12-month guarantee.
Getting the site ready
- Let building users know which areas are affected

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Advice
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Crumbling edges that would give a new bead nothing sound to grip
- Movement on a scale no sealant is meant to absorb
- Changing the joint layout or spacing of a structure
If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think.
Surfaces we seal
- Car park decks and ramps
- Brickwork movement joints
- Cladding panel joints
- Blockwork control joints
- Podiums and floor movement joints
- Precast concrete panel joints
What we are called out for in Stone Hill
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again unless width and product are reviewed.
Clients usually get in touch after noticing one or more of the following:
- Debris jammed in movement joints
- Expansion joints split through the centre of the bead
- Car park joints leaking onto vehicles below
- Brittle, chalky sealant on external joints
Schools like Sellindge Primary School often have long brick elevations with movement joints that age quietly.

What happens if it’s left?
A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we’ll tell you honestly. For buildings around smaller places like Stone Hill, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Why us?
- Products installed to the manufacturer’s instructions
- One number for every site we cover
- 12-month guarantee on workmanship
- A range of standard colours, depending on the product
Different surfaces, different methods
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it.
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.
Questions about Stone Hill
Is Stone Hill too small for you to travel to?
Not at all. Stone Hill is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is hospital work, at somewhere like William Harvey Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
What do you charge?
Each job is quoted on its own details. For yours, call the office on 01277 525 020 or email drawings and photos with a description of the work.
Joints that move: notes for Stone Hill
Stone Hill has two 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. Stone Hill sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.
A healthcare site such as William Harvey Hospital (to the north-west of Stone Hill) depends on car parks, ramps and service yards whose joints take traffic all day. Another example is Mersham-le-Hatch Business Village, 2.1 miles to the north-west of Stone Hill, where floors and yards would be done in stages around the occupiers.
