Need expansion joint sealing in Newington?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Newington need work, visits can be combined. You will have a fixed quote before work starts.

  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 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. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Move anything stored against the joints
  • Let us know about inductions and permits
  • Tell us which areas need to stay in use

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Expansion joint sealing in Newington, done properly

A movement joint only works while its seal does. Once it fails, water, grit and debris get in, the joint can’t close properly and its edges begin to crumble. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on cladding panel joints, blockwork control joints and car park decks and ramps, and the usual reasons a site gets in touch are spalled or broken joint edges in floors and decks and hardened, cracked sealant on exposed facades. A single leaking joint is often how a building in Newington first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Newington, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Questions about Newington

Does your area include sites such as Shorncliffe Industrial Estate, near Newington?

Yes. We cover Newington and the area around it, including industrial estates, business parks and retail parks such as Shorncliffe Industrial Estate. To start, just call the office on 01277 525 020 or email us with the unit, the joints involved and your access times.

Is hospital work, at somewhere like Royal Victoria Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

What if there’s asbestos in the old mastic?

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

How long will the joint resealing take?

It usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. We’ll confirm when each area can be used again.

Do you guarantee expansion joint work?

Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.

Can you quote from photographs?

It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.

What happens if it rains on the day?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside so external dates keep some flexibility.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Leaks coming from the membrane rather than the joint seal
  • Proprietary pre-formed expansion joint systems
  • Changing the joint layout or spacing of a structure

Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

What we are called out for in Newington

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.

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

  • Joints where the bead has lost adhesion
  • Damp inside where a wall movement joint has failed
  • Water dripping through deck or ramp joints
  • Layers of sealant in a movement joint

Warehouse floors on estates like Shorncliffe Industrial Estate (1.4 miles south-east of Newington) carry pallet trucks and forklifts over every saw-cut joint.

What your quote should include

  • How the existing material will be dealt with
  • Which product they’ll use, and why it suits the joint
  • How they’ll work around occupants
  • Are they CHAS accredited or on Constructionline?

Questions to ask before you appoint anyone

What the job involves on each surface

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Close-up photographs help us judge the joints, or we visit if they don’t show enough.

Car park decks and ramps

Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again, and we will tell you if any edges need repairing first.

Where floor joints take the most wear near Newington

Newington lies within about 2 miles of the sea. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, and edges left open tend to break up faster. Newington sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.

Phasing is what makes joint work possible on busy sites such as Golden Valley Shopping Centre (1.5 miles south-east of Newington): one bay, aisle or car park row at a time. For an estate such as Royal Victoria Hospital, 2.5 miles to the east of Newington, the joints in ramps, decks and long building elevations all need attention over time.

Newington is about 2 miles north-east of Hythe, in Kent. We cover commercial sites throughout Newington, whether it’s a single job or part of a planned programme. 931 places across Kent fall within our area, including Newington. We also cover Brighton, around 57 miles from Newington.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

What affects the price in Newington

Your fixed quote is built from the real scope. It takes account of:

  • The size and state of each joint
  • Which sealant the job calls for
  • Removal of failed or old sealant
  • The total length or number of joints

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Specification clauses that apply
  • The postcode of the building
  • Approximate linear metres or a joint schedule
  • Clear photos of the problem areas

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email a schedule or drawings.
