About our expansion joint sealing in Charlton
Long runs of brick or block have movement joints built in. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied. Site teams most often ask us about sealant pulling off the joint face and new sealant over old, now failing, across podiums and floor movement joints, brickwork movement joints and precast concrete panel joints. Searching for sealant specialists in Charlton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Smaller community and commercial buildings around Charlton have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

Questions we’re asked in Charlton
Is Charlton too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of 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.
Can you work at a site such as Sunbury International Business Centre, by Charlton?
Yes. We cover Charlton and the area around it, including industrial estates, business parks and retail parks such as Sunbury International Business Centre. Photos and a short description are enough for a first look.
How long will the joint resealing take?
Allow anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Timings are set out in the quote, including any phasing.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
What sealant do you use in movement joints?
Movement capability matters most, classified under BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.
When can you be on site?
We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Where floor joints take the most wear near Charlton
At about 16 miles from central London, Charlton is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift. The 3 miles around Charlton take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
Hospitals like Ashford Hospital, 2.6 miles north-west of Charlton, have multi-storey or surface car parks whose joints carry vehicles round the clock. Another example is Shepperton Business Park, which lies south of Charlton, where floors and yards would be done in stages around the occupiers. For buildings at a park such as Sunbury International Business Centre (0.8 miles north-east of Charlton), brick and panel movement joints are easy to forget until one leaks.

On site: what to expect
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Charlton may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Tell staff and tenants when we’ll be in
- Tell us which areas need to stay in use
- Share your working hours and any access restrictions

Advice

What happens if it’s left?
Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now. We can split the scope into urgent and planned. For buildings around smaller places like Charlton, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Why us?
- Fixed quotes based on photos, drawings or a visit
- Products installed to the manufacturer’s instructions
- Colours chosen to suit frames, cladding or finishes where possible
- Fully insured, including public liability cover

Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Reopen bays and walkways only after the stated cure time
- Act on the first tear or lifting edge rather than waiting
- Keep product details with the building records for the next reseal
- Include every elevation and deck joint in periodic inspections
Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.
What affects the price in Charlton
We price every job individually. The things that drive the figure:
- The product specified
- Location, for remote and island sites
- Phasing around occupants
- Whether old sealant has to be cut out first
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
Sending details for a quote
However big the job, the same details help:
- Photos of the joints, close up and from further back
- Where the site is, with the postcode
- Any dates the work must fit around
- Anything awkward about access or site hours
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Owners, agents and contractors
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 will confirm with the quote.
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
