Expansion joint sealing for businesses in Afton

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

Your questions answered

Must our site in Afton stop work while the joints are done?

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

Is a smaller place like Afton outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Does the weather affect joint sealing?

Outside work depends on conditions: rain, frost and condensation all stop sealant bonding. Internal floor joints are far less affected.

Do you seal on top of existing sealant?

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

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

How we handle expansion joint sealing in Afton

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. If the arrises are already broken, we’ll say so before sealing, and phased work keeps areas in use. If you are dealing with torn sealant in brick or block movement joints and damp inside where a wall movement joint has failed, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Afton, that means joint design, primers and backing rod as standard.

Jobs around smaller places like Afton are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Expansion joint sealing in Afton: the local picture

Afton lies within about 1 mile of the sea. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so it pays to keep them sealed. Afton sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, while winter salting gets into any joint left open.

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

Afton is about 6 miles south of Lymington, in the Isle of Wight. Afton sits inside our coverage and the rest of the Isle of Wight, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our the Isle of Wight coverage takes in 125 places. Southampton is covered too, around 18 miles from Afton.

Postcode districts covered here: PO40. We cover commercial and managed buildings on Bay Road, Afton Road and Manor Road and the roads nearby. Just outside Afton, we also work in Afton Park (1 mile east), Easton (1 mile west), Freshwater (1 mile north-west), Norton Green (1 mile north) and Colwell (1 mile north-west). Bigger towns within reach include Newport (9 miles east), Ryde (15 miles east), Cowes (10 miles north-east), Sandown (15 miles east), Shanklin (15 miles east) and Ventnor (14 miles south-east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Redoing a failed joint usually costs more than getting it right at the outset, 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.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Afton may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Getting the site ready

  • Warn occupants and staff about the work

Surface by surface

Cladding panel joints

We confirm what access is in place before pricing. Close-up photos help us judge the joints, or we visit if they don’t show enough.

Joints between different materials

Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces, with primer where specified.

Cost factors for movement joints

A fixed quote reflects the actual work. It allows for:

  • The total length or number of joints
  • Removal of failed or old sealant
  • Induction, permit and paperwork requirements
  • The product specified

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

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • The product your specification calls for
  • The asbestos register, for older buildings

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or send details through our quote form.

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Crumbling edges that would give a new bead nothing sound to grip
  • Cracking or settlement that calls for an engineer’s assessment

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we’ll tell you honestly.

Surfaces we seal

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