Planning Guide


October 5, 2015
Shearmac has successfully completed the supply and installation – Aluminium Joinery trade for Synlait Administration Building in Dunsandal for us.
Shearmac have met their budget and performed with the highest of professionalism given the construction program was very tight in a very complex build.
Their attention to detail and workmanship has been excellent.
Our Foreman and staff have found them to be capable and skilled on site.

Calder Stewart would recommend Shearmac for any future work.

Shearmac Aluminium was appointed the contract for the supply and install of the aluminium joinery at our recently completed Hotel refurbishment project at 165 Cashel St, which was rebranded “Breakfree on Cashel”. The project involved seismically upgrading the two existing buildings and complete refurbishment of these buildings which comprise the largest hotel in Christchurch with 263 rooms.
The contract initially involved the supply only of new double glazing units to one of the facades damaged by adjacent demolition; Shearmac was able to offer an unmatched lead time for these at a very competitive price. As the scope of the project progressed, so did the size of the aluminium package with another substantial stage added to construction including a complex frameless glass entry lobby and several other windows and doors, more than doubling the scope of the project.
This was no problem to Shearmac who took on the challenge and were able to deliver their project on time and within an ever tightening construction programme. We worked together on some of the details and created some bespoke detailing using some of the profiles available to Shearmac with some fantastic results.

After completion of a hassle free project, I have no reservations in recommending Shearmac Aluminium for future commercial works.

From our very first contact through to installation the service has been fantastic. What matches this is the thermally broken aluminium windows and doors. We had the aluminium joinery installed in Spring 2013. I’ve waited till after Winter 2014 to have a verdict on the windows and doors from Shearmac.
The words that come to mind to describe thermally broken aluminium windows and doors are brilliant, warm, dry, great investment.
When I was told less condensation forming on the aluminium windows and doors I was somewhat sceptical. How wrong I was. No sign of moisture forming on windows or the aluminium jonery.
I’ve also noted heating costs haven’t increased in this much larger home. I put this mainly down to the thermally broken aluminium joinery.
To the team at Shearmac, thank you for the fantastic service with a great product. Will certainly be recommending Shearmac to friends and family. More importantly the thermally broken aluminium joinery.

We had our windows and doors installed yesterday and wanted to let you know how happy we are with them, I never thought I would be so excited about windows & doors. From a purely aesthetic point of view I was impressed with the overall style and the bathroom windows are better than I imagined I’m so happy we won’t have to cover them up with blinds for privacy and I’m in love with the stacker doors. We hope to be in our new home for at least 25 years and when we planned our build we viewed the thermally broken aluminium as a smart investment in our future as we put a lot of though into having a well insulated home and with all the positive comments from our amazing builder I know we made the right choice with your product, thank you for helping us make our dream home come true.

You delivered the joinery to our home yesterday. We were on site last night and we are thrilled that the windows and doors will all be in before Christmas so that the exterior cladding can be be commenced. Having the windows in and the way forward clear is a big morale boost for us!
Also I want to thank you again for your good advice about modifying the kitchen window, we are very pleased with the outcome. The fact that you took the time to contact me and offer your advice and experience is much appreciated. Dealing with a customer focused supplier like you is very special and makes the process and outcomes so much more enjoyable.

At Shearmac Aluminium quality materials and skilled staff… create happy clients: We would like to thank Steve for his excellent service and his effort in sorting out the little details such as handles, flashings, etc. He was friendly and professional to deal with and nothing was a problem for him.
We are very pleased with the new windows and our decision to go with Timberview was certainly the right one. They have given us all the benefits of modern low maintenance aluminium windows while maintaining the character of the house we were trying to retain with the timber on the inside.
Once again we would like to thank you and we would certainly have no hesitation in recommending Shearmac and Timberview to anyone else considering new or replacement windows.
