Questions we’re asked in Woodcote Green

Can you work in a London building with booked loading and goods-lift slots?

Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

Is hospital work, at somewhere like Purley War Memorial Hospital, something you do?

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.

What hours do you work?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Is colour matching possible?

In many cases, 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.

What guarantee do you give on joint sealing?

The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.

How do we ask for a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email the details over. Include photos or drawings if you have them.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Expansion joint sealing in Woodcote Green, done properly

We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic and we name it in the quote. The enquiries we see most involve arrises breaking up along floor joints and brittle, chalky sealant on external joints, across podiums and floor movement joints, cladding panel joints and brickwork movement joints. For commercial sealant work in Woodcote Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

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 Woodcote Green means thinking about access, loading times and the ULEZ as well as the joints.

A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, call 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Why deal with it now?

On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open. We agree phasing with you before work starts. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What you get with us

  • Colour options checked against the specified product
  • RAL and finish matching where the product range allows
  • 12 months’ guarantee on every job
  • Sealing commercial buildings since 2005

Traffic, movement and joints around Woodcote Green

London car parks, loading bays and podium decks often can’t close for long, so joints are sealed in sections with each area handed back once cured. Woodcote Green has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

Another example is Silver Wing Industrial Estate (1.7 miles north-east of Woodcote Green), where floors and yards would be done in stages around the occupiers. Hospitals like Purley War Memorial Hospital (to the east of Woodcote Green) have multi-storey or surface car parks whose joints carry vehicles round the clock. Estates like Ullswater Industrial Estate (to the south-east of Woodcote Green) combine warehouse slabs, yards and loading bays, all with joints under wheels.

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. Planning a London job such as one in Woodcote Green starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Let us know about inductions and permits
  • Send any specification or drawings in advance

What sets the cost

The price varies from site to site. Expect it to depend on:

  • How accessible the joints are
  • Whether the work must be split into stages
  • Location, for remote and island sites
  • Whether old sealant has to be cut out first

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.

Details that help us quote

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

  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around
  • Specification clauses that apply
  • The postcode of the building

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

Looking after the joints

Cleaning and maintenance staff play a part too. Share these points with them:

  • Report split or peeling joint sealant early
  • Put movement joints on the planned maintenance inspection round
  • Look over external and deck joints after a hard winter
  • Keep traffic off new joints until the cure time is up

On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal and a look at the joints after winter catches any damage.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. A sound seal keeps the joint working.

Should maintenance staff do it?

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Honest limits

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Concrete or masonry repairs along the arrises
  • Waterproofing layers buried beneath the sealant
  • Proprietary pre-formed expansion joint systems

Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Surfaces we seal

  • Podiums and floor movement joints
