Expansion joint sealing for Colbury sites

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

After the work

Regular inspection catches problems early. In particular:

  • Act on the first tear or lifting edge rather than waiting
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Include every elevation and deck joint in periodic inspections
  • Keep racking legs and heavy point loads off floor joints

Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.

An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.

About our expansion joint sealing in Colbury

Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. If you have expansion joints split through the centre of the bead and debris jammed in movement joints, we can put it right. Searching for sealant specialists in Colbury? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Smaller community and commercial buildings around Colbury have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Colbury 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 start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Share your working hours and any access restrictions
  • Send any specification or drawings in advance
  • Send asbestos survey details if the building is pre-2000

Advice

Honest limits

Being straight saves everyone time. New sealant won’t cure:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Movement on a scale no sealant is meant to absorb
  • Crumbling edges that would give a new bead nothing sound to grip

If you are not sure, just speak to us on 01277 525 020 or use the quote form and we will give you a straight answer.

Where floor joints take the most wear near Colbury

Colbury lies within about 2 miles of the sea. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, which is why split joints are worth sealing before the edges deteriorate. Colbury is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint.

Hospital campuses such as Tatchbury Mount Hospital, 2.3 miles to the north-west of Colbury, grow in stages, leaving movement joints wherever new blocks meet old. Campuses like Southampton Solent University, 4.6 miles east of Colbury, mix old and new buildings, with movement joints wherever they meet. Centres like Totton Shopping Centre (to the north-east of Colbury) have mall floors and service decks whose joints carry steady traffic.

Colbury is about 1 mile south of Totton, in Hampshire. Colbury sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Across Hampshire, 723 places are covered, including Colbury.

FAQs: Colbury

Does a coastal location like Colbury affect which sealant is used?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

Is Colbury too far out for you?

No. Places such as Colbury are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

What happens if it rains on the day?

A wet joint can’t be sealed properly, so external work waits for suitable conditions. The work is simply moved to the next suitable day.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

How long will the joint resealing take?

It usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. We confirm the timescale with the quote, including any phasing.

Is movement joint sealing guaranteed?

A 12-month guarantee covers our workmanship and we hold public liability insurance. Keeping joints clear of debris helps them last.

Quoting for work in Colbury

Each job is priced on its own details. The things that drive the figure:

  • Whether the work must be split into stages
  • Distance, for remote addresses
  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Sending details for a quote

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

  • How the joints are reached, and at what height
  • Whether an asbestos survey exists
  • Clear photographs of the problem areas
  • Your programme or deadline

A good quote starts with a clear picture: 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.

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
