Expansion joint sealing for commercial buildings in Addiscombe
Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors for buildings in Addiscombe. The enquiries we see most involve spalled or broken joint edges in floors and decks and joints where the bead has lost adhesion, across blockwork control joints, podiums and floor movement joints and cladding panel joints. Searching for sealant specialists in Addiscombe? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Around Addiscombe, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and our waste is bagged and taken away as we go. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Tell us which areas need to stay in use
- Move anything stored against the joints
- Have the specification and drawings to hand

What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- 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)
- A joint that has to be widened or re-detailed before it can work
Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly.
Surfaces we seal

Traffic, movement and joints around Addiscombe
London car parks, loading bays and podium decks often can’t close for long, so we seal in sections and hand areas back as each cures. Less than 3 miles from Addiscombe there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.
Across sites such as Pilton Industrial Estate, 1.8 miles west of Addiscombe, floor and movement joints can be sealed in phases so units keep working. For an estate such as Shirley Oaks Hospital (less than half a mile east of Addiscombe), the joints in ramps, decks and long building elevations all need attention over time.

What affects the price in Addiscombe
The price varies from site to site. Expect it to depend on:
- Distance, for remote addresses
- Backing rod, priming and other preparation
- Which sealant the job calls for
- Phasing around occupants
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Sending details for a quote
To price the job accurately, we need to understand the site. Useful things to include:
- Approximate linear metres or a joint schedule
- How the joints are reached, and at what height
- The postcode of the building
- Whether the building will be occupied during the work
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Do you need expansion joint sealing in Addiscombe?
Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks, so it can’t follow the movement any more.
Typical triggers for a call:
- Layers of sealant in a movement joint
- Sealant peeling off one face of the joint
- Movement joints with split or torn sealant
- Joints packed with grit and debris
In a school such as Oasis Academy Shirley Park, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Questions we’re asked in Addiscombe
Do you take on work at healthcare sites like Shirley Oaks Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them.
Can you quote from photos?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Plan racking layouts so feet don’t land on a joint
- Keep stones and debris out of open joint lines
- Record the sealant used and the date in the O&M file
- Include every elevation and deck joint in periodic inspections
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears. Regular sweeping keeps joint lines clear.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Resealing early limits the damage.
