Need construction mastic in Flexford?

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

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

About our construction mastic in Flexford

The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. Site teams most often ask us about sanitary sealant damaged by following trades and cracks opening in caulked internal joints, on brick and block movement joints, cladding and panel joints and floor and skirting junctions. A single leaking joint is often how a building in Flexford 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.

For a site near Flexford, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.

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

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near Flexford may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. First we look at the scope on site or from drawings.
  2. You receive a fixed quote covering scope, products and sequence.
  3. Paperwork is agreed and applicators are inducted on site.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Any frame gaps or issues outside our scope are flagged to the site team.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

Before we start on site

  • Let us know about inductions and permits
  • Warn occupants and staff about the work
  • Send asbestos survey details if the building is pre-2000

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Specifying the product where the designer hasn’t
  • Glazing units that are cracked or misted
  • Damage to finishes by other trades after we have sealed

If you are not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer before you book.

Surfaces we seal

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

Quoting for work in Flexford

What shapes the price:

  • Quantities, in metres or numbers
  • The size and state of each joint
  • Removal of failed or old sealant
  • Whether the work must be split into stages

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What we need to price the job

A good diagnosis starts with the right details. Tell us:

  • Anything awkward about access or site hours
  • Drawings or a marked-up plan, if available
  • The type of building and who uses it
  • Any dates the work must fit around

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Questions we are asked in Flexford

Can you work on a hospital site such as Royal Surrey County Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Flexford too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can you work plot by plot or floor by floor?

The programme sets the job. Share the release dates and we’ll match our work to them, sealing as areas become ready.

Can the building stay open while you work?

Typically, yes. We phase the work so most of the building stays in use.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

What guarantee comes with a mastic package?

The work is guaranteed for 12 months, covering how we sealed. Keeping other trades off finished joints prevents most problems.

Why deal with it now?

Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility, with the same standard on every plot. One visit to deal with every failing joint makes more sense than several trips to a place like Flexford, rather than one at a time. Send photos of each area and we will quote for the lot.

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Mastic packages on Flexford sites

At about 31 miles from central London, Flexford is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Flexford sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

For contractors at a school such as Wyke Primary School, sealing has to be finished before term starts. Building work at universities like University of Surrey - Manor Park Campus, 2.7 miles to the east of Flexford, is often timed for the summer, mastic included. Hospital estates such as Royal Surrey County Hospital, 2.7 miles east of Flexford, 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.

Flexford is about 4 miles east of Aldershot, in Surrey. Our applicators travel to Flexford for work on mastic packages. Flexford is one of 379 places we cover in Surrey for mastic packages. Reading is covered too, some 19 miles away.
