Hardley: questions and answers

Is Glenmore Business Park, near Hardley, within your area?

Yes. Our area takes in Hardley and its surroundings, with estates and business parks such as Glenmore Business Park included. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Is a hospital such as Hythe Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What do you charge?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Can you clear a mastic snag list before handover?

Yes. Snag-only work is something we take on.

Can you work plot by plot or floor by floor?

We seal plot by plot or floor by floor as areas are released. The sequence is agreed with the site manager at the start and adjusted as things change.

Construction mastic for commercial buildings in Hardley

Mastic follows everyone else, which means it absorbs every delay upstream. The sequence is set with the site team and updated as plots or floors are handed over. That keeps the work right first time and saves rework. Most enquiries involve sealant knocked or painted over by other trades and new external sealant already peeling away, across brick and block movement joints, floor and skirting junctions and internal decorators’ caulk. Facilities teams, main contractors and managing agents in Hardley tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Sites around smaller places like Hardley can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

What the job involves on each surface

Bathrooms, en suites and washrooms

On multi-unit schemes, consistency matters across hundreds of bathrooms. One applicator team gives the same finish everywhere.

Internal decorators’ caulk

Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move while moving joints need a flexible sealant.

When something else is needed

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

  • Joints damaged after sign-off by following trades
  • Glazing units that are cracked or misted
  • Oversized gaps that need packing or adjustment by others

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Where we work in Hardley

  • Sanitary and kitchen joints
  • Internal decorators’ caulk
  • Cladding and panel joints
  • Window and door perimeters
  • Floor and skirting junctions
  • Brick and block movement joints

Building and refurbishing in Hardley

With the shore within about 2 miles, Hardley counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. Rainfall across the South East, Hardley included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.

Hospital estates such as Hythe Hospital (to the north of Hardley) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. For contractors refurbishing units at places like Glenmore Business Park, which lies north-west of Hardley, the mastic covers cladding panels, roller-door and window perimeters.

Hardley is about 2 miles south of Hythe, in Hampshire. Across the SO45 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Hampshire coverage takes in 723 places, large and small.

Business premises anywhere in SO45 are within our area for mastic packages. Among the streets we cover are Harrier Way, Harrier Green and Falconer Court. Nearby places we also cover include Little Holbury (1 mile south), Holbury (1 mile south), Frostlane (1 mile north), Roughdown (1 mile south) and Blackfield (2 miles south-east). Nearby towns on our patch include Gosport (11 miles east), Eastleigh (9 miles north), Fareham (9 miles east), Totton (7 miles north-west), Chandler's Ford (10 miles north) and Hedge End (7 miles north-east).

Local landmarks in Hardley

Around Hardley, our work takes us to commercial buildings near Manor Church of England Infant School. The nearest railway station is Netley station, roughly 3.3 miles north-east of the centre.

Signs you need construction mastic in Hardley

Frames installed with uneven gaps make perimeter sealing harder. Sealant has a range of joint widths it can cope with, so gaps outside that range need sorting by the installer first. We flag them early rather than filling them with sealant that won’t last.

Look out for the following:

  • Different trades sealing to different standards
  • Oversized or tapered gaps around new frames
  • Snag items on joints that need redoing before handover
  • Internal caulk splitting as the building dries out

On a campus such as Southampton Solent University, 4.8 miles north of Hardley, new teaching buildings and residences are typically built and refurbished around the academic year.

What to look for in a quote

  • What site paperwork they can supply
  • Do they follow the manufacturer’s priming guidance?
  • Proof of insurance
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Questions to ask before you appoint anyone

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Ask installers to correct oversized gaps first
  • Keep scrapers and abrasive pads off new beads
  • Brief following trades on areas that have been sealed
  • Put any product change through the designer first

At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known. We can confirm the handover information you need when we quote.

External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work.

What affects the price in Hardley

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Access and working height
  • Whether the work must be split into stages
  • Which sealant the job calls for
  • Site requirements such as inductions and permits

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

Sending details for a quote

To price the job accurately, we need to understand the site. Send us:

  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older
  • Access details, including height
  • Approximate linear metres or a joint schedule

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or phone 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

From enquiry to sign-off

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. Smaller jobs around Hardley can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we take quantities off the drawings and read through the specification.
  2. You receive a fixed quote listing scope, products and phasing.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. Work follows the programme, area by area, as rooms and elevations become ready.
  5. Each joint is prepared, backed to depth and sealed in the product the specification names.
  6. We close out snagging and hand over with a 12-month guarantee.

Getting the site ready

  • Point out parking and an unloading spot
  • Point out any areas we must not close
  • Confirm the product named in the specification
