Expansion joint sealing for businesses in Great Sampford

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Why deal with it now?

A torn seal left alone normally gets worse. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. One visit to deal with every failing joint makes more sense than several trips to a place like Great Sampford. Photos of every joint help us quote for the whole job.

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

About our expansion joint sealing in Great Sampford

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. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. We work on cladding panel joints, brickwork movement joints and podiums and floor movement joints, and what we’re called in for most is sealant pulling off the joint face and new sealant over old, now failing. Looking for mastic applicators who cover Great Sampford? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

For a site near Great Sampford, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Different surfaces, different methods

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.

Cladding panel joints

We confirm what access is in place before pricing. Close-up photos help us judge the joints.

Your questions answered

Do we have to stop operations in Great Sampford while the joints are sealed?

Typically not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.

Is Great Sampford too small for you to travel to?

No. Places such as Great Sampford are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

What do you charge?

Each job is quoted on its own details. To get one, phone 01277 525 020 or email the details over.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Concrete or masonry repairs along the arrises
  • Cracking or settlement that calls for an engineer’s assessment
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

What we seal

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

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Great Sampford are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  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

  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed
  • Move anything stored against the joints

Advice

After the work

Keep the joints in good shape with a few simple steps:

  • Inspect exposed joints once the cold weather has passed
  • Put movement joints on the planned maintenance inspection round
  • Keep stones and debris out of open joint lines
  • Record the sealant used and the date in the O&M file

Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records.

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 and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.

Floors, slabs and movement joints in Great Sampford

Central London is about 40 miles from Great Sampford. The roads out of London are lined with trade parks and distribution sheds. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.

For floors and slabs around Great Sampford, the product is chosen for the traffic and the movement at each joint. In a school such as Great Sampford Community Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
