Common questions from Old Malden clients

Do you work in London buildings with loading restrictions?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method.

Can you work at a site such as Beverley Trading Estate, by Old Malden?

Yes. We cover Old Malden and the area around it, including industrial estates, business parks and retail parks such as Beverley Trading Estate. A few photos and the unit address let us price the work.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Do you offer coloured sealant?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

About our floor joint sealing in Old Malden

Few warehouses can shut a whole floor while joints are done, so the work is split into zones and treated one area at a time. Share your site hours and access windows and the programme is built around them, with goods still moving in the areas we aren’t in. We work on joints along racking aisles, construction joints and saw-cut induced joints, and what we are called in for most is open saw cuts full of debris and flexible sealant torn out by wheels. For commercial sealant work in Old Malden, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around Old Malden, 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.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Leave it or put it right?

Waiting for a site-wide shutdown often means the joints keep getting worse. Phased in zones, the busiest routes can be treated first while the rest of the floor carries on. Failed sealant in a building in Old Malden can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why appoint us

  • Constructionline member
  • Work carried out by CSCS-carded applicators
  • Work to your specification and the manufacturer’s guidance
  • A fixed quote before work starts

The 3 miles around Old Malden 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.

For a centre such as Bentall Centre, 3 miles north-west of Old Malden, the service yard and car park joints usually need attention first. Across sites such as Shannon Commercial Centre, 2.1 miles north-east of Old Malden, floor and movement joints can be sealed in phases so units keep working.

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

What we are called out for in Old Malden

Joints near dock doors see colder air, rain blown in and water off vehicles on top of the heaviest turning movements. They are often the first on a site to break down.

Site and facilities staff are often the first to spot these:

  • Broken arrises where pallet trucks cross
  • A gap opening alongside old joint filler
  • Saw-cut joints left open and packed with grit
  • Drivers complaining about joints on a route

A healthcare site such as Tolworth Hospital, 0.9 miles west of Old Malden, depends on car parks, ramps and service yards whose joints take traffic all day.

Before you book anyone

  • Which product they’ll use, and why it suits the joint
  • Whether old or failed sealant will be cut out, not overlaid
  • Their pre-qualification and accreditations
  • How they’ll work around occupants

Choosing a commercial sealant contractor

How the quote is worked out

Before we quote, we look at:

  • The total length or number of joints
  • Removal of failed or old sealant
  • Travel to remote or island sites
  • Access and working height

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What we need to price the job

We can often quote from photos and a few details. Please tell us:

  • Asbestos survey details if the building is older
  • Your programme or deadline
  • A wide shot and a close-up of the area
  • Drawings or a marked-up plan, if available

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

When to bring in a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. In Old Malden, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. First, the zones and order of work are agreed with you.
  2. Any joints with broken edges are flagged before work starts.
  3. We clear each run back to clean concrete.
  4. We fill the joints with the agreed product, finished level.
  5. You get a time for each zone to reopen.

Before we start on site

  • Make sure the joints can be reached
  • Point out any areas we must not close
  • Tell us what induction or permit system the site runs
