Expansion joint sealing in Bexley Riverside

Few joints take as much punishment as those in a car park. 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, phasing bays so the car park can stay in use. If you have expansion joints split through the centre of the bead and car park joints leaking onto vehicles below, we can put it right, on cladding panel joints, car park decks and ramps and precast concrete panel joints alike. Whoever orders the work in Bexley Riverside, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn.

Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or use the quote form and we’ll come back to it.

Quoting for work in Bexley Riverside

A fixed quote reflects the actual work. It takes account of:

  • Whether the work must be split into stages
  • Distance, for remote addresses
  • How much there is to seal
  • Induction, permit and paperwork requirements

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Whether the building will be occupied during the work
  • Specification clauses that apply
  • The site address and postcode
  • Drawings or a marked-up plan, if available

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, phone 01277 525 020 or email a schedule or drawings.

Questions about Bexley Riverside

Is Madford Trade Park, near Bexley Riverside, within your area?

Yes. We cover Bexley Riverside and the area around it, including industrial estates, business parks and retail parks such as Madford Trade Park. Photos and a short description are enough for a first look.

Can you cope with the access rules in a London building?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it.

Is movement joint sealing guaranteed?

A 12-month guarantee covers our workmanship, and we’re fully insured for public liability. Regular sweeping and inspection help the joints last.

What if the joint edges are damaged?

A bond is only as strong as the material behind it, so we’ll tell you if the edges need repairing before sealing. Where it’s visible beforehand, we’ll say so when we quote.

Can you quote from photographs?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Do you have public liability insurance?

Yes. Mastic Doctor is fully insured, public liability included.

What happens if it’s left?

Doing joint resealing alongside other planned works can save on access. But joints already letting water in shouldn’t wait for a programme. We can split the scope into urgent and planned. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

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.

Why us?

  • Colour agreed before work starts
  • Our applicators hold CSCS cards
  • Fully insured, including public liability cover
  • Matching to RAL references, product permitting

Different surfaces, different methods

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies.

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.

On site: what to expect

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. All of Greater London is in the ULEZ, and kerbside space in Bexley Riverside can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Preparing the site

  • Point out parking and an unloading spot
  • Tell us which areas need to stay in use
  • Confirm the product named in the specification

General trades versus a specialist

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.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
