Expansion joint sealing in Heart's Delight

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

Why it’s worth doing now in Heart's Delight

Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. We cut out the old seal and prepare the faces every time. Halls, stores and units around places like Heart's Delight may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Joints that move: notes for Heart's Delight

The South East is one of the drier parts of the UK. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint. At about 37 miles from central London, Heart's Delight is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London.

Another example is Newington Enterprise Centre, 2.6 miles to the north-west of Heart's Delight, where floors and yards would be done in stages around the occupiers. In a school such as Minterne Community Junior School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Heart's Delight is about 1 mile south-west of Sittingbourne, in Kent. If you are looking for expansion joint sealing in Heart's Delight, we can help, as we do across Kent. 931 places across Kent fall within our area, including Heart's Delight. London is covered too, some 37 miles away.

What we are called out for in Heart's Delight

When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.

Clients typically get in touch after noticing one or more of the following:

  • Movement joints with split or torn sealant
  • Sealant peeling off one face of the joint
  • Hardened, cracked sealant on exposed facades
  • Joints packed with grit and debris

A healthcare site such as Sittingbourne Memorial Hospital (to the east of Heart's Delight) depends on car parks, ramps and service yards whose joints take traffic all day.

Choosing a commercial sealant contractor

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Heart's Delight are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We look at the joints, their width and how they’ve failed.
  2. You get a fixed quote with the product and its movement capability stated.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Before we start on site

  • Share the asbestos register for older buildings
  • Share your working hours and any access restrictions
  • Explain the parking and delivery arrangements

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Keep product details with the building records for the next reseal
  • Look over external and deck joints after a hard winter
  • Keep scrapers and ploughs from dragging across joint sealant
  • Treat a small split as a warning, not a cosmetic issue

Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles. Resealing early limits the damage.

Cost factors for movement joints

We price every job individually. The things that drive the figure:

  • Backing rod, priming and other preparation
  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints
  • Whether old sealant has to be cut out first

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

What we need to price the job

However big the job, these details speed things up:

  • Rough lengths or quantities, or drawings if you have them
  • What the building is and how it’s used
  • The postcode of the building
  • Anything awkward about access or site hours

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. If you have questions first, ring 01277 525 020 or email drawings and photos.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Leaks coming from the membrane rather than the joint seal
  • Cracking or settlement that calls for an engineer’s assessment

If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer.

Surfaces we seal

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.

Is a smaller place like Heart's Delight outside your area?

Not at all. Heart's Delight is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is movement joint sealing guaranteed?

The workmanship is guaranteed for 12 months from sign-off. Keeping joints clear of debris helps them last.

Are you fully insured?

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

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
