Expansion joint sealing near Yelsted

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Signs you need expansion joint sealing in Yelsted

Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability.

Common reasons buildings call us in:

  • New sealant over old, now failing
  • Water getting into the wall through a failed joint
  • Torn sealant in brick or block movement joints
  • Brittle, chalky sealant on external joints

Retail sites such as Parkwood Shopping Centre, 1.5 miles to the north-west of Yelsted, have car park, service yard and shop floor joints under constant traffic.

Questions to ask before you book

  • Proof of insurance
  • Who will actually carry out the work
  • What site paperwork they can supply
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

Yelsted: questions and answers

Can you take on a job at a hospital such as KIMS hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is a smaller place like Yelsted outside your area?

No. Places such as Yelsted are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

What sealant do you use in movement joints?

It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks usually need a polyurethane unless the specification names something else.

Are you CHAS accredited and on Constructionline?

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

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Can you work on car park ramps and decks?

Yes. Tell us how the car park is used and which areas must stay open, and we will plan the phasing around it.

What timescale should we allow for resealing expansion joints?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Clear dirt from joint lines during routine cleaning
  • Check joints after long freezing spells
  • Record the sealant used and the date in the O&M file
  • Plan racking layouts so feet don’t land on a joint

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check and long before edges start to break. Should you spot a problem, you can give us a call on 01277 525 020 or send photos by email and send a picture.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Catching it early keeps the water outside.

Quoting for work in Yelsted

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

  • Whether old sealant has to be cut out first
  • Site requirements such as inductions and permits
  • How much there is to seal
  • Travel to remote or island sites

Pricing movement joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • When you need the work done
  • Drawings or a marked-up plan, if available
  • Clear photographs of the problem areas
  • Whether an asbestos survey exists

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or send photos by email if you’d rather talk the job through.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Damaged metal nosings or cover plates over a joint

If you are not sure, just call the office on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Joints that move: notes for Yelsted

At least three named trading, business or retail sites lie within about 3 miles of Yelsted. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Yelsted sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.

Hospitals like KIMS hospital (to the south-west of Yelsted) have multi-storey or surface car parks whose joints carry vehicles round the clock. Another example is Hempstead Valley Shopping Centre, 2.1 miles to the west of Yelsted, where floors and yards would be done in stages around the occupiers.

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a building around Yelsted, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Share the asbestos register for older buildings
  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand
