Need expansion joint sealing in Sibley's Green?

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, 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.

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 easy to get wrong without experience.

About our expansion joint sealing in Sibley's Green

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. We will tell you if the edges need repairing before sealing, and phased work keeps areas in use. If you have water getting into the wall through a failed joint and layers of sealant in a movement joint, we can help, on cladding panel joints, precast concrete panel joints and brickwork movement joints alike. Most enquiries from Sibley's Green start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

In and around smaller places like Sibley's Green, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Why act early in Sibley's Green

Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed. For buildings around smaller places like Sibley's Green, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • A range of standard colours, depending on the product
  • Old sealant cut out, never sealed over
  • Constructionline member
  • Colours confirmed for the specified product

Read our cost guide or how we’re accredited.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Keep product details with the building records for the next reseal
  • Keep traffic off new joints until the cure time is up
  • Inspect exposed joints once the cold weather has passed
  • Raise snow-clearing blades over deck joints where possible

Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in and long before edges start to break. If anything looks wrong, give us a call on 01277 525 020 or send photos by email with photographs.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Sealing the joint promptly stops it at source.

Warehouse floors and decks around Sibley's Green

Central London is about 35 miles from Sibley's Green. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint.

Schools such as Putteridge High School have movement joints in their walls and floors that are easy to overlook. In and around Sibley's Green, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. If others near Sibley's Green need work, visits can be combined. A fixed quote is given before anything starts.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take.
  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. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close
  • Point out parking and an unloading spot

Advice

Questions we’re asked in Sibley's Green

Do we have to stop operations in Sibley's Green while the joints are sealed?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.

What site paperwork comes with a job in Sibley's Green?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Is any job too small?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

What timescale should we allow for resealing expansion joints?

Allow anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Timings are set out in the quote, including any phasing.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can you quote from photographs?

It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs usually get a visit.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

How the quote is worked out

To price the job, we consider:

  • Backing rod, priming and other preparation
  • How much there is to seal
  • Removal of failed or old sealant
  • Distance, for remote addresses

The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • Whether an asbestos survey exists
  • Where the site is, with the postcode
  • How the joints are reached, and at what height
  • Any specification or named product

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
