Expansion joint sealing in Great Stonar

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

Signs you need expansion joint sealing in Great Stonar

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.

Any of the following is a good reason to get the joints checked over:

  • Rain penetration at brick or block movement joints
  • Leaks through car park deck joints onto the level below
  • Spalled or broken joint edges in floors and decks
  • Sealant pulling off the joint face

Large sites such as Ramsgate General Hospital (to the north-east of Great Stonar) have car parks, service roads and long elevations with movement joints in brick and panels.

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • Proof of insurance
  • Which product they’ll use, and why it suits the joint
  • Will RAMS and insurance details be available?

FAQs: Great Stonar

Can you work at a site such as Birnham Farm Business Centre, by Great Stonar?

Yes. Our area takes in Great Stonar and its surroundings, with estates and business parks such as Birnham Farm Business Centre included. Photos and a short description are enough for a first look.

Is Great Stonar too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Can you work on car park ramps and decks?

Yes, we do. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed and broken edges are flagged before sealing.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Diagnose, treat, sign off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. Rural sites near Great Stonar may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We start with photos, 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. Edges are checked, and we tell you if any need repairing before sealing.
  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.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Tell us which areas need to stay in use
  • Warn occupants and staff about the work

When to bring in a specialist

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. That’s why many clients bring in a specialist from the beginning.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Commercial clients in Great Stonar

Building owners and managing agents use us on everything from one building to a spread of sites around Great Stonar. One quote can cover more than one site, so there’s one set of paperwork to deal with.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

How the quote is worked out

Before we quote, we look at:

  • Location, for remote and island sites
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first
  • Quantities, in metres or numbers

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What we need to price the job

A good diagnosis starts with the right details. Tell us:

  • How the joints are reached, and at what height
  • Drawings or a marked-up plan, if available
  • Photos of the joints, close up and from further back
  • What the building is and how it’s used

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • Reopen bays and walkways only after the stated cure time
  • Treat a small split as a warning, not a cosmetic issue
  • Keep scrapers and ploughs from dragging across joint sealant
  • Include every elevation and deck joint in periodic inspections

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint, well after the seal first opened. Catching it early keeps the water outside.

Where floor joints take the most wear near Great Stonar

Great Stonar sits close to the coast, within about 2 miles. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner.

For a school such as Sandwich Infant School, playground and building joints can be done in the holidays. Business parks such as Birnham Farm Business Centre, 2.9 miles to the south-west of Great Stonar, have car parks, paved areas and long brick and panel elevations, all with movement joints.
