Different surfaces, different methods

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.

Brickwork and blockwork joints

Long brick and block elevations have movement joints at intervals. They take a low-modulus sealant with a movement class to suit.

What we can’t put right

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Crumbling edges that would give a new bead nothing sound to grip
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

If in doubt, call 01277 525 020 or email us and we’ll say what we think.

What we seal

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

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building around Sevenoaks Weald, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  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. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Tell staff and tenants when we will be in
  • For older buildings, check the asbestos register before work
  • Tell us which areas need to stay in use

Why deal with it now?

Doing joint resealing alongside other planned works can save on access. But joints already letting water in shouldn’t wait for a programme because damage continues. Urgent joints now, the rest later, is often the sensible plan. Halls, stores and units around places like Sevenoaks Weald may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Why us?

  • Health and safety: CHAS accredited
  • Colour options checked against the specified product
  • Fully insured, including public liability cover
  • Colours chosen to suit frames, cladding or finishes where possible

Your questions answered

Is Sevenoaks Weald too far out for you?

Not at all. Sevenoaks Weald is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Do you cover business parks and estates near Sevenoaks Weald, such as Salters Heath Business Centre?

Yes. Our area takes in Sevenoaks Weald and its surroundings, with estates and business parks such as Salters Heath Business Centre included. Photos and a short description are enough for a first look.

What do you charge?

There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

What happens if it rains on the day?

Weather matters for any external joint. Indoor joints can usually carry on regardless.

What timescale should we allow for resealing expansion joints?

The metres of joint, the access and the amount of removal decide it. As a guide, it normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.

When to call us in Sevenoaks Weald

Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.

Things that usually lead to an enquiry:

  • Expansion joints filled with dirt and stones
  • Weathered movement joint sealant that no longer flexes
  • Rain penetration at brick or block movement joints
  • Leaks through car park deck joints onto the level below

Hospital campuses such as Hollanden Park Hospital, 2.8 miles south-east of Sevenoaks Weald, grow in stages, leaving movement joints wherever new blocks meet old.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • How the existing material will be dealt with
  • Whether their applicators hold CSCS cards
  • What site paperwork they can supply
