Surface by surface
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix and flag it if the membrane looks like the source.
Expansion joint sealing in Waterside, done properly
Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. A sealant suited to traffic and the expected movement goes in. Site teams most often ask us about water getting into the wall through a failed joint and chipped joint edges on forklift routes, across brickwork movement joints, blockwork control joints and podiums and floor movement joints. A specialist sealant contractor works differently from a general builder: on jobs in Waterside, preparation and product choice get the time they need.
Jobs around smaller places like Waterside are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we will take it from there.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

How a job runs
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you. For work around Waterside, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We assess the joints on site or from photos, noting widths and how each has failed.
- 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.
- 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.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Preparing the site
- Send your site hours and access windows
- Agree which areas must stay open
- Tell staff and tenants when we’ll be in

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:
- Joints too narrow for the movement, which need redesigning by the engineer
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Damaged metal nosings or cover plates over a joint
If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think before you book.
Joints and surfaces we work on
- Car park decks and ramps
- Blockwork control joints

Aftercare for building managers
Regular inspection catches problems early. In particular:
- Act on the first tear or lifting edge rather than waiting
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Look over external and deck joints after a hard winter
- Include every elevation and deck joint in periodic inspections
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears. Regular sweeping keeps joint lines clear.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.
Why deal with it now?
Resealing is usually the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. We’ll flag where edges need repair before sealing. One visit to deal with every failing joint makes more sense than several trips to a place like Waterside, rather than one at a time. Send photos of each area and we will quote for the lot.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Questions we’re asked in Waterside
Is Waterside off your patch?
Not at all. Waterside is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Is hospital work, at somewhere like Amersham Hospital, something you do?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you use silicone or polyurethane in movement joints?
The right product depends on the joint. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints.
How do you deal with asbestos in old sealant?
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. We don’t remove asbestos-containing materials.
What happens if it rains on the day?
Weather matters for any external joint because a damp or frozen joint won’t take a proper bond. Indoor joints can normally carry on regardless.
Is colour matching possible?
That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
Owners, agents and contractors
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Expansion joint sealing around Waterside: how the place shapes the job
The 3 miles around Waterside take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Waterside lies roughly 26 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.
For a school such as Waterside Primary Academy, playground and building joints can be done in the holidays. For an estate such as Amersham Hospital (2.5 miles south of Waterside), the joints in ramps, decks and long building elevations all need attention over time. Across sites such as Corinium Industrial Estate, which lies south of Waterside, floor and movement joints can be sealed in phases so units keep working.
Waterside is about 1 mile south of Chesham, in Buckinghamshire.
