Common questions from Balcombe clients
Is Balcombe off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does a site in Balcombe have to shut while its joints are sealed?
Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Expansion joint sealing in Balcombe
Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we will say so before sealing. We work on brickwork movement joints, cladding panel joints 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 previous reseals laid over old sealant. A single leaking joint is often how a building in Balcombe first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places such as Balcombe, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
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.

What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- The total length or number of joints
- How much existing material needs removing
- Whether the work must be split into stages
- Which sealant the job calls for
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What we need to price the job
There’s no need for a formal survey. These details are enough to start:
- Whether the building will be occupied during the work
- The postcode of the building
- Anything awkward about access or site hours
- Whether an asbestos survey exists

For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
General trades versus a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Signs you need expansion joint sealing in Balcombe
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:
- Spalled or broken joint edges in floors and decks
- Weathered movement joint sealant that no longer flexes
- Damp inside where a wall movement joint has failed
- Torn sealant in brick or block movement joints
For a school such as Balcombe CofE Controlled Primary School, playground and building joints can be done in the holidays.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- How they’ll work around occupants
- How the joint faces will be prepared and primed
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Floors, slabs and movement joints in Balcombe
Balcombe lies roughly 31 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Rainfall across the South East, Balcombe included, is lower than in many parts of the UK. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.
Hospitals like Princess Royal Hospital (to the south of Balcombe) have multi-storey or surface car parks whose joints carry vehicles round the clock.

On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Balcombe need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- 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.
Getting the site ready
- Flag any permit to work we will need
- Share your working hours and any access restrictions
- Arrange parking or a loading space
Ask for a quote

Advice
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Movement on a scale no sealant is meant to absorb
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If in doubt, call 01277 525 020 or send photos by email and we will say what we think.
