Expansion joint sealing in Beddington, done properly

Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors. If you have hardened, cracked sealant on exposed facades and leaks through car park deck joints onto the level below, we can put it right, on brickwork movement joints, blockwork control joints and podiums and floor movement joints alike. One point of contact handles commercial sealant work in Beddington from the first photographs to the final walk-round, whether it’s one building or several.

Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. Planning a job in Beddington means thinking about access, loading times and the ULEZ as well as the joints.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Changing the joint layout or spacing of a structure
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

If in doubt, call 01277 525 020 or email the details over and we’ll say what we think.

Where we work in Beddington

  • Cladding panel joints
  • Blockwork control joints
  • Car park decks and ramps
  • Brickwork movement joints
  • Precast concrete panel joints
  • Podiums and floor movement joints

What we are called out for in Beddington

When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.

Common reasons buildings call us in:

  • Torn sealant in brick or block movement joints
  • Layers of sealant in a movement joint
  • Joints where the bead has lost adhesion
  • Expansion joints filled with dirt and stones

For an estate such as Croydon University Hospital, which lies north-east of Beddington, the joints in ramps, decks and long building elevations all need attention over time.

Our contractor checklist

Our process

Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For a job in Beddington, access comes first. Send the building rules and access times with your enquiry.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Point out parking and an unloading spot
  • Tell staff and tenants when we’ll be in

FAQs: Beddington

Do you work in London buildings with loading restrictions?

Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Is Anchor Business Park, near Beddington, within your area?

Yes. Our area takes in Beddington and its surroundings, with estates and business parks such as Anchor Business Park included. Photos and a short description are enough for a first look.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

How much does the work cost?

Each job is quoted on its own details. For yours, call 01277 525 020 or email a schedule or drawings with a description of the work.

Which product is best for expansion joints?

Whatever suits the joint and the specification. The quote states the sealant and its movement class so there are no surprises.

How do I request a quote?

You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email a schedule or drawings. Include photos or drawings if you have them.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Note which joints were done, when, and with what
  • Keep traffic off new joints until the cure time is up
  • Clear dirt from joint lines during routine cleaning
  • Brief car park operatives to protect joint lines during winter clearance

Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint and we will tell you when each bay or area can reopen. Keeping the area coned off until then avoids tyre marks and damage.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.

What sets the cost

Each job is priced on its own details. The main factors are:

  • Phasing around occupants
  • Induction, permit and paperwork requirements
  • Distance, for remote addresses
  • Quantities, in metres or numbers

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Sending details for a quote

However big the job, the same details help:

  • Approximate linear metres or a joint schedule
  • How the joints are reached, and at what height
  • The type of building and who uses it
  • Asbestos survey details if the building is older

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Different surfaces, different methods

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately or a site visit fills the gaps.

Brickwork and blockwork joints

Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, normally low-modulus laid over backing rod at the correct depth.

Joints that move: notes for Beddington

The 3 miles around Beddington 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. Basement car parks and service yards in London tend to be in use all working day, so we seal in sections and hand areas back as each cures.

At places like Progress Business Park, 0.5 miles north-east of Beddington, joints are sealed a section at a time so operations carry on. Business parks such as Anchor Business Park, less than half a mile to the north-east of Beddington, have car parks, paved areas and long brick and panel elevations, all with movement joints.

Beddington is about 2 miles west of Croydon, in Greater London. Anywhere in CR0, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

We also cover Bandonhill (1 mile south), Wallington (1 mile south-west), Waddon (1 mile south-east), Old Town (1 mile east) and Roundshaw (1 mile south) for movement joints. A short drive away, we cover London (9 miles north), City of Westminster (10 miles north), Marylebone (10 miles north), Kensington (9 miles north), St Pancras (11 miles north) and Shoreditch (11 miles north).
