Ashford: questions and answers

Is Ashford off your patch?

No. Places such as Ashford are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Do you cover business parks and estates near Ashford, such as Fordingbridge Business Park?

Yes. Our area takes in Ashford and its surroundings, with estates and business parks such as Fordingbridge Business Park included. A few photos and the unit address let us price the work.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

What guarantee comes with a mastic package?

Each package is backed by a 12-month guarantee. We’re also fully insured for public liability.

Is any job too small?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you take on mastic snagging only?

Yes. We clear snags by redoing joints rather than patching them to suit the programme.

How long do sealant joints last?

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

Construction mastic in Ashford

We work to the specification and the programme, not to habit. If a product is named, that’s what goes in. Joint widths, backing, primers and tooling follow the manufacturer’s guidance. We work on cladding and panel joints, sanitary and kitchen joints and floor and skirting junctions, and what we’re called in for most is external joints sealed in damp or cold conditions that are now failing and oversized or tapered gaps around new frames. Most enquiries from Ashford start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Conversions of older rural buildings near smaller places such as Ashford bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Designing joint widths or choosing the specification (that sits with the designer)
  • Faulty frames rather than failed sealant
  • Oversized gaps that need packing or adjustment by others

If in doubt, call the office on 01277 525 020 or use the quote form and we will say what we think.

Where we work in Ashford

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

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near Ashford may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. Drawings, specification and programme come to us.
  2. Quantities are measured and a fixed price returned.
  3. The sequence is agreed with the site manager.
  4. Plots or floors are sealed as they’re handed over.
  5. Joints are prepared, backed and sealed to the specification.
  6. After snagging, the work is handed over under our 12-month guarantee.

What we need from you

  • Move anything stored against the joints
  • Tell us your opening times and when work is allowed
  • Arrange parking or a loading space

Request a quote

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, call the office on 01277 525 020 or email the details over.

Advice

Construction mastic around Ashford: how the place shapes the job

Ashford is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.

Older buildings in the area around Ashford, such as Breamore House, 3 miles north of Ashford, need care when sealed: the product has to suit soft or historic materials. For a contractor at a hotel such as Greyhound Hotel (0.7 miles east of Ashford), the mastic often has to be finished before a reopening date.

Ashford is in Hampshire. Any commercial site in Ashford is covered, for single jobs and planned programmes alike. 723 places across Hampshire fall within our area, Ashford among them. Our Southampton page has more on work in that area (18 miles or so).

We cover the SP6 postcode districts for mastic packages. If your site is on Station Road, Rookwood Gardens and Ashford Close or close by, send details and we will quote for mastic packages. Sites close to Ashford are covered too, including Sandleheath (1 mile west), Alderholt (2 miles south-west), Damerham (2 miles north-west), Rockbourne (3 miles north-west) and Broxhill (3 miles west). A short drive away, we cover Totton (13 miles east), Romsey (15 miles east), New Milton (14 miles south-east), Ringwood (6 miles south), Barton on Sea (14 miles south-east) and Ashley (14 miles south-east).

Landmarks near Ashford

What affects the price in Ashford

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

  • Working within restricted access windows
  • The size and state of each joint
  • How accessible the joints are
  • Distance, for remote addresses

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What to include in your enquiry

However big the job, these details speed things up:

  • Clear photos of the problem areas
  • The site address and postcode
  • How the joints are reached, and at what height
  • Any dates the work must fit around

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Looking after the joints

A few simple habits keep the new joints working:

  • Bring the mastic contractor in after the last trades are through
  • Brief following trades on areas that have been sealed
  • Put any product change through the designer first
  • Keep product details for future maintenance

If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit.

Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out, and avoids a rush.

What we are called out for in Ashford

Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding, so preparation matters as much here as on a reseal.

Things that usually lead to an enquiry:

  • Frame gaps too wide for sealant alone
  • Failed sealant in an existing building being refurbished
  • Sanitary sealant damaged by following trades
  • Frame perimeters left unsealed or poorly sealed

Hospital estates such as Fordingbridge Hospital, 0.6 miles east of Ashford, 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.

What your quote should include

  • How the existing material will be dealt with
  • What level of public liability insurance do they hold?
  • What the guarantee covers, and for how long
  • How they handle RAMS and site documents

Our contractor checklist

Surface by surface

External facade and movement joints

Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.

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.
