About our facade sealing in Smannell

Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. Site teams most often ask us about leaks at window and door perimeters and perimeter joints where frames meet the structure, across perimeter joints where frames meet the structure, window and door perimeters and cladding panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Smannell it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Conversions of older rural buildings near smaller places such as Smannell 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.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

New build and refits around Smannell

The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. Smannell lies roughly 61 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.

On a healthcare site such as Andover Hospital (Grounds) (2.4 miles south-west of Smannell), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors at a college like Andover College, 2.3 miles to the south-west of Smannell, perimeters and internal sealant are timed for the holidays. When a school such as Smannell and Enham Church of England (Aided) Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Smannell is about 2 miles north-east of Andover, in Hampshire. We cover commercial sites throughout Smannell, whether it’s a single job or part of a planned programme. We work across 723 places in Hampshire. There’s a separate page for Southampton, about 22 miles away.

We cover the SP11 postcode districts for facade joints. For a building on Stoke Road and Smannell Road or nearby, we can quote for facade joints. Just outside Smannell, we also work in Little London (1 mile north), Finkley (1 mile south-east), Enham Alamein (1 mile west), Upper Enham (1 mile north-west) and East Anton (1 mile south-west). Bigger towns within reach include Basingstoke (15 miles east), Winchester (14 miles south-east), Hyde (13 miles south-east), Tidworth (9 miles west), Weeke (13 miles south-east) and Kempshott (14 miles east).

Why deal with it now?

Failed joints let in more than water: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. Around Smannell, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

A quote for facade joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

What you get with us

  • CHAS accredited contractor
  • A range of standard colours, depending on the product
  • One phone line for London, the South East and Scotland
  • CSCS-carded applicators

Questions about Smannell

Could you schedule work at a campus like Andover College for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you take on work at healthcare sites like Andover Hospital (Grounds)?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Do you replace failed glazing units?

No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters across the facade.

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Surface by surface

Precast concrete panels

Joints between precast panels carry real movement. We use a sealant with the right movement capability, set over backing rod with primer where the product requires it.

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Water getting in through cracked render or porous masonry
  • Movement beyond what any sealant can handle
  • Cracked or spalling substrates that need repair before sealing

If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Where we work in Smannell

  • Cladding panel joints
  • Perimeter joints where frames meet the structure
  • Stone and brick facade joints
  • Coping and flashing joints
  • Window and door perimeters
  • Shopfront frames

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. Rural sites near Smannell 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. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Share the asbestos register for older buildings
  • Point out any areas we must not close
