Construction mastic for businesses in Upton

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

Construction mastic in Upton, done properly

Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. If you have frame perimeters left unsealed or poorly sealed and snag items on joints that need redoing before handover, we can help, on brick and block movement joints, sanitary and kitchen joints and floor and skirting junctions alike. Whoever orders the work in Upton, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Conversions of older rural buildings near smaller places such as Upton bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Surface by surface

External facade and movement joints

Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.

Snagging before handover

Damaged, missed or untidy joints make up most snag lists. Snagging can be included or priced separately.

When to call us in Upton

Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.

Look out for the following:

  • Inconsistent sealant finishes from plot to plot
  • New external sealant already peeling away
  • Cracks opening in caulked internal joints
  • Failed sealant in an existing building being refurbished

Further education sites such as Totton College (to the south-west of Upton) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Before you book anyone

  • Which product they’ll use, and why it suits the joint
  • What site paperwork they can supply
  • Whether primer will be used where the manufacturer specifies it
  • Will failed sealant be removed rather than covered?

Questions to ask before you appoint anyone

Site staff or a sealant specialist?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Designing joint widths or choosing the specification (that sits with the designer)
  • Rework caused by others damaging completed areas
  • Defective windows, doors or glazing units (the supplier or installer’s job)

Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly.

Joints and surfaces we work on

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

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

From enquiry to sign-off

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. If others near Upton need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we take quantities off the drawings and read through the specification.
  2. A fixed quote sets out the scope, the products and the sequence.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. We seal each plot or floor as it’s released to us.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. Snags are cleared before handover and completed areas carry our 12-month guarantee.

What we need from you

  • Send your site hours and access windows
  • Send any specification or drawings in advance
  • Tell us what induction or permit system the site runs

Mastic packages on Upton sites

Upton is within about 3 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Rainfall across the South East, Upton included, is lower than in many parts of the UK. 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.

On a campus such as University of Southampton, 3.4 miles to the south-east of Upton, new teaching buildings and residences are normally built and refurbished around the academic year. Hospital estates such as Princess Anne Hospital (to the south-east of Upton) 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.

Upton is about 2 miles north-west of Regents Park, in Hampshire. Anywhere in SO16, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Upton is one of 723 places in Hampshire on our list for mastic packages.

We cover the SO16 postcode districts for mastic packages. Among the streets we cover are Upton Lane, Romsey Road and Greenwood Avenue, and sites on any of them can send details for a fixed quote. We also cover Nursling (1 mile south), Rownhams (1 mile east), Ashfield (1 mile north-west), Toothill (1 mile north) and Hillyfields (1 mile south). Nearby towns on our patch include Winchester (10 miles north-east), Eastleigh (6 miles east), Fareham (14 miles south-east), Totton (3 miles south-west), Chandler's Ford (4 miles north-east) and Hedge End (8 miles east).

Your questions answered

Does your area include sites such as Nursling Industrial Estate, near Upton?

Yes. We cover Upton and the area around it, including industrial estates, business parks and retail parks such as Nursling Industrial Estate. A few photos and the unit address let us price the work.

Is Upton off your patch?

Not at all. Upton is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

What will the job cost?

Each job is quoted on its own details. To get one, phone 01277 525 020 or email drawings and photos with a description of the work.

Will you quote for a small job?

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

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
