“We have much pleasure in recommending Alteration Specialists for any building or alteration work. The alterations done to our property are exactly what we asked for and we are thrilled with the results. Managing Director Justin Green was prompt in providing us with a quote and plan for our kitchen and bathroom alterations. He listened to our ideas whilst making helpful suggestions. He was consistently reliable, approachable, professional and was always prompt in responding to our questions!

Much care was taken on our property and we were always contacted and consulted over any problems that arose and these were always taken care of professionally. The team of builders/trades people we had working on our property were great – friendly, professional and we always felt they were striving to do the best for us.

Alteration Specialists take much pride in their work and this can be seen in the quality of finish. They only work with skilled tradespeople so our tiling and paint work etc are of a very high standard. We have no hesitation in recommending them and would definitely use them again! Thanks Justin.”

“Over a five-year period, Alteration Specialists have undertaken work on our home. These included renovations to our; bathroom, toilet, kitchen and laundry, and the addition of a new deck. Justin is a true professional and something that we liked is that he spoke to us, non-builder people in simple terms, and used his professional knowledge and judgement to explain why our ideas could or couldn’t work, and where applicable solid cost effective solutions. They are a very experienced and friendly team who we felt completely comfortable having in our home, in fact, we missed them when they finished. We can’t recommend them highly enough.”

“Could not be more happy with the team at Alteration Specialists – thanks Cliffy, Robbo and Justin. It was a hassle-free experience for us and intend on doing more work with the team. The guys were able to share their years of experience to recommend the best solution, line up all the external trades, and turn the job around quickly, on time and at the best quality.”

“We would recommend Alteration Specialists to anyone looking to make renovations to their property. Right from the first time we met Justin, they were always on time and professional. They listened to what we wanted, took the time to understood us as a family, what we needed, and made some great suggestions. Rob and the team were always prompt, professional, hardworking and became part of the family during our 12-month renovation. We were always consulted over any issues that arose and jointly we came up with solutions that met our needs. Alteration Specialists take pride in their work and the tradesmen they use are also expected to meet their high standards, ensuring that are respectful, professional and they clean up after themselves each day. Our renovation was almost a complete rebuild, with only one wall remaining the same, and they managed to complete this job while our family of 4 stayed in the house as well, no mean feat. We are really delighted with how our renovation worked out and recommend this team to anyone looking to do any alterations.”

“We wanted a top quality job on our renovations, and Justin and his team provided us with just that – fantastic workmanship and loads of care and attention to the details. You wouldn’t know we “added on”, they melded the old and the new perfectly – we now just have a larger more comfortable, quality home. Despite being a big renovation, Justin did a great job at making sure that we could stay put for as long as possible, which was really important to us. We were amazed at how tidy the team were, despite all the mud of a winter time build. They always left the site secure and safe at the end of each day, so we didn’t have to worry about our young children living in the middle of a construction zone! Justin has a fantastic team working with him, they are all polite, respectful and courteous – and they were accommodating to our needs. A big build or renovation can be stressful, but these guys made it enjoyable….we were delighted with the finished product, but we were also sad to see Justin and his team go! These guys are honest and hard working. They know how to quality build, they know how to manage a large project and they take the time to communicate with their clients, even when it is wet, muddy and super busy!”

“Hi Justin, I don’t usually write these kind of letters. I wrote one for the real estate agent but she asked me to… I want to start by saying I was very nervous about having builders come into my house. Your builders quickly put my fears to rest as they were at all times very professional and approachable. Your foreman Robbo was friendly and informative at all times with all aspects of the job we had asked of your company. All staff were also incredibly hardworking and thoughtful toward my boys. At one point my shed uplifted in the strong Palmerston North winds and your builders kindly managed to stop the shed from blowing out of my property and secured the shed to the fence. I am very grateful for that. I am very also happy with the work that has been done. The two rooms look great and I feel more secure now that I know that the ceiling and floors in the two rooms have been corrected by your builders. I would be happy to recommend Alteration Specialists. Thank you”

“We highly recommend Justin and his team and will certainly use them again for any future work. They were professional, friendly, timely and on-budget and their work was of an excellent standard. Great project management, excellent liaison with the subcontractors and a wonderful end result made our renovation a very positive experience.”

“I have no hesitation in recommending Justin Green and Alteration Specialists. They were great to work with. From the beginning with the promptness of the quote, there was always great communication about how the job was progressing and what was involved with the week’s work. Justin managed his team of sub contractors very well. All his team of workers were professional and did a first class job. They were all really friendly and great to chat with. It has been over a year since our job was completed and we have had no post construction issues at all. We love our renovation and this is due to the great team at Alteration Specialists.”
