Custom Box Gutter Replacement – Redwood, Christchurch Project

Completed replacement of a deteriorated 12-metre box gutter on a residential property in Redwood. Works included removing the existing guttering and brackets, installing a new custom-fabricated 0.55 mm COLORSTEEL Magna box gutter in Ebony, and fitting new support straps. A new fall line was established to improve drainage towards the downpipe. Existing fixing holes were sealed with weatherproof roofing screws, and all joints were riveted and sealed. The new guttering and downpipe were installed, with all waste materials removed from site. Services: Spouting replacement, custom sheet metal installation, roof drainage improvements and exterior maintenance

Commercial Joint and Sealant Repairs

Completed targeted concrete crack and joint sealing at a commercial property following water ingress through affected floor areas. The work included removing loose material, cleaning and preparing the joint surfaces, and installing backing rod where required to support the sealant and control application depth. Sika 3-N Primer and Sikaflex PRO-3 Purform was applied to the prepared joints and carefully tooled to produce a continuous, tidy finish. Attention was given to adhesion along the concrete edges and adjoining surfaces, creating a flexible seal across the treated areas. Before-and-after photographs and completion reporting documented the work, with remaining areas identified for further maintenance.

Verandah Spouting Replacement

Replaced approximately 6 metres of deteriorated verandah spouting with new Gothic-profile spouting in Grey Friars, complementing the existing roof and maintaining the character of the verandah. The work involved removing the old guttering, fitting the replacement run and connecting it to the existing drainage. Localised rust treatment was also completed around the bullnose roof junction and adjoining valley. Loose corrosion was mechanically removed, the affected metal prepared, and three protective treatment coats applied. Localised sealant repairs were completed at deteriorated sections, with the coatings and sealant allowed to cure for more than 24 hours. Before-and-after photographs documented the work. Further maintenance recommendations were provided for separate roof flashing joins and weathered roof coatings.

Commercial Gutter & Downpipe Elbow Repairs

Completed repairs to a leaking metal gutter and downpipe elbow at a commercial property in Christchurch. Works included removing deteriorated sealant, cleaning and preparing the affected joints, and applying new roofing and gutter sealant to restore weather resistance and reduce the risk of water ingress. Repairs were undertaken outside normal business hours to minimise disruption and manage public safety around the building entrance. Additional inspections identified drainage obstructions and deteriorating sections of architectural box guttering. Recommendations for further repairs and preventative maintenance were provided. A photographic completion report was supplied to the property management team, documenting the repairs and additional observations. Services: Commercial gutter repairs, downpipe maintenance, exterior waterproofing, building inspections and preventative property maintenance.

Roof Restoration, Rust Treatment & Painting – Canterbury

Completed roof restoration and painting work on a residential property in Canterbury. Works included pressure washing the existing metal roof to remove accumulated dirt, debris and surface contaminants in preparation for painting. Corroded areas were prepared and treated with rust protection products to reduce further deterioration. Additional repairs included reshaping damaged roofing sheets and installing a custom sheet metal closure at the roof apex to improve weather protection. The roof was then coated to restore its appearance and provide additional surface protection. Services: Roof painting, pressure washing, rust treatment, sheet metal repairs, roof maintenance and restoration

Gable Window Flashing Sealant Repairs Christchurch

Completed weatherproofing repairs to a residential property's gable flashing and weatherboard junction in Halswell, Christchurch. Works included inspecting and preparing an existing 10 mm gap between the metal flashing and weatherboard cladding. The affected area was cleaned and prepared before applying exterior-grade flexible sealant to close the gap and reduce the risk of water ingress. The sealant was neatly finished to provide a durable, weather-resistant joint. Services: Flashing repairs, exterior sealant application, weatherproofing and general property maintenance.
