About our facade sealing in Hurstbourne Priors

Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. We work on window and door perimeters, coping and flashing joints and perimeter joints where frames meet the structure, and the failures we are asked to look at most are failed sealant on precast panel joints and perimeter joints where frames meet the structure. Searching for sealant specialists in Hurstbourne Priors? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Conversions of older rural buildings near smaller places such as Hurstbourne Priors 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.

Work we carry out in Hampshire comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Signs you need facade sealing in Hurstbourne Priors

Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and tears as the joint moves.

Any of the following is a good reason to get the joints checked over:

  • Failed seals around shopfront and entrance frames
  • Water coming in around window frames
  • New sealant peeling off old mastic
  • Perimeter sealant that has split or peeled away

Recladding or extending a unit at a site like Ardglen Industrial Estate, 2 miles north-east of Hurstbourne Priors, brings panel joints and frame perimeters into the programme.

What to look for in a quote

  • Are they CHAS accredited or on Constructionline?
  • Will failed sealant be removed rather than covered?
  • How they handle RAMS and site documents
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Hurstbourne Priors. One quote can cover more than one site, which keeps the paperwork simple.

Our process

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, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Hurstbourne Priors are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

What we need from you

  • Tell us what induction or permit system the site runs
  • Let building users know which areas are affected
  • Point out parking and an unloading spot

Advice

Mastic packages on Hurstbourne Priors sites

Hurstbourne Priors is about 59 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. The South East is one of the drier parts of the UK. 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.

Projects at schools like Testbourne Community School work to term dates, so mastic is programmed tightly. New wings at hospitals like Andover War Memorial Hospital, 5.2 miles to the west of Hurstbourne Priors, bring long runs of window and panel joints to seal.

Hurstbourne Priors is about 5 miles east of Andover, in Hampshire. Across the RG28 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Hampshire, 723 places are covered, including Hurstbourne Priors. Southampton is covered too, around 20 miles from Hurstbourne Priors.

Commercial sites across RG28 are covered for facade joints. Just outside Hurstbourne Priors, we also work in Firgo (2 miles south-east), Whitchurch (2 miles north-east), Wells-in-the-Field (3 miles north-east), St Mary Bourne (3 miles north) and Freefolk (3 miles north-east). Bigger towns within reach include Basingstoke (12 miles east), Winchester (11 miles south), Andover (5 miles west), Tadley (14 miles north-east), Hyde (10 miles south) and Popley (14 miles east).

Doing it in-house

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Movement beyond what any sealant can handle
  • Specialist high-level access methods
  • Damaged frames that need replacing

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly.

Joints and surfaces we work on

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

What happens if it’s left?

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. For buildings around smaller places like Hurstbourne Priors, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.
