    "This is the third time I have had Cossie Builders do work on my house.
    This job was a lot smaller than others but they still made me feel that this job was just as important as the others.
    Everything once again was delivered on time and on budget - and Mandy’s excellent communication skills were impeccable.
    Thanks so much.
    Mandy Cosgrove responded:
    "You are most welcome Pip! Thank you so much! We are always happy to work in your lovely home with your gorgeous views. Cheers, Mandy."

    "Cossie Builders completed an extensive renovation of one side of our house including asbestos removal, weatherboard recladding, new windows, balcony and lower deck.
    We found Cossies professional, efficient and they took pride in their work. We lived and worked in the house during the construction, and they were very considerate of this, communicating work activities regularly, and also advising of any change variations or rescheduling promptly. They delivered to the planned schedule.
    Quality was generally of a high standard. However, we had a couple of issues with the accuracy from two of Cossie’s suppliers, but Cossies did their best to remedy these.

    Would recommend Cossie Builders and use them again. Thanks James, Mandy, and Andy!

    "James and Mandy are the dream team! Mandy created an incredible
    schedule for our alteration so we knew who was on site and when. It was accurate! We also knew when we had to have things like fittings and tiles chosen so that everything flowed to the correct date. Mandy was always available and nothing was too much trouble. James is calm and organised. He and his team are so lovely to have around the house.
    The renovation went smoothly. Believe or not, it was actually stress free. Our family lived through the build and we missed having James and the team around once they were gone! We now have a new roof, family room, extra bedroom and en-suite. And we love it.

    We highly recommend the Cossie Builders team.

    "We were first time very green renovators and the least stressful part of our renovation was the build itself! This was due to the professionalism and amazing and constant communication from James and Mandy during the whole process. We lived in our house during the build and every night we came home to a clean and tidy building site which also made the build very pain free. James and Mandy always provided solutions and variations to the build where never a problem. The Cossie subbies were also very professional and easy to deal with. We are so happy with the quality of the products and workmanship from Cossie and their subbies and are looking forward to working again with them soon!"

    "Cossie Builders completed an extensive renovation of my home in Wilton over winter 2018. The team were amazing to work with, providing me with advice and support and always on hand to answer any questions and solve problems. Despite working over winter, in challenging conditions outside, my new roof and extension were completed on time and the entire job was even finished early. Their extensive quotation and fixed pricing meant there were no unexpected extra costs, and I have settled into my new home with complete confidence in the quality of the workmanship from James, Andy and all their subcontractors.

    If its a hassle free build, on time and budget, that you are after, you can't go past Cossie Builders.

    "We used Cossie Builders for our kitchen and living area renovation in 2017. I couldn't recommend them more highly. From the moment we met James and Mandy we were impressed with their professionalism. James is very knowledgeable and offers sound advice and excellent craftsmanship. He project manages the job from start to finish in a timely and efficient manner. He also brought with him an excellent team of specialist tradesman who always conducted themselves professionally when in our home. Mandy provides a detailed and thorough quote for the job at the outset, along with work schedules for each week of the project and weekly invoices. She is always available to answer any questions big or small and helps to resolve issues that may arise. James and Mandy delivered the project on time and to the price that they quoted. My family and I couldn't be more happy with the renovation Cossie Builders carried out for us. We love our new space! Thanks again James and Mandy."

    "We embarked on a major renovation of our house last year while leaving in it. I was anxious about the idea but Cossie Builders took care of business. They started the date they said they would, arrived on time every single day and finished the job on time and with the quality, we were expecting. Mandy organizational and communication skills are just superb. They provided us with a timetable so we would know exactly what was going on, when and who would be around. James and Andy are great to deal with. They try to make the whole process as stress-free as possible. We will most definitely call them back should we require and want to do any other works around the house."

    "This is the second time I have employed Cossie Builders to do work on my house. The first job was to re roof, and arrange painting of my house, and the second job was to remove walls and prep for kitchen installation.
    Right from the word go they gave me a level of comfort that everything would be spot on with the quote I received. It detailed everything that was included as well as a schedule of each day I could expect to happen. Any variations to this was discussed the evening prior so I knew who would be on site each day.

    Any issues I had were fixed immediately, so I really felt like a valued client. I would recommend them to anyone who was undertaking and renovation work.

    "We embarked on an extensive renovation of our home in the second half of 2015. After collecting ideas, finalising designs and committing to working drawings & plans we reached out to 3 builders- all who came highly recommended. After our initial meeting with James & Mandy Cosgrove it became very obvious that Cossie Builders would provide the communication& professional building skills &services that would suit us best. In fact, their service, follow up , plan of action and comprehensive building itinerary was exceptional and well beyond other builders we had quote for us. James and his assistant carpenter along with his preferred and suggested sub contractors; plumbers, electricians, joiners, window suppliers, tilers, plasterers and painters were all superb. They were always professional, courteous and hardworking. We quickly had trust and confidence in Cossie Builders in a time that can provide many stresses.

    James & Mandy were able to project manage our renovation , know and supply all building materials needed, itemise materials and give care &attention to detail. Timings were thoughtful & courteous so we could use our current kitchen for as long as possible before we would be without water.

    Mandy runs a tight ship; incredibly organised and reliable, payment invoices were sent out weekly and further communication on progress and what to expect of the coming weeks was always at our fingertips. She exhibited excellent communication with sub contractors, and us, and was exceptionally efficient.

    James was fantastic; always open to suggestions and would respond with experienced and skilled expertise. He was always punctual, up front and on top of his tradies. He consistently maintained and demanded high standards and professional service and a top work ethic from all his sub contractors. Another service we really appreciated was his tidiness in the work place and at the end of the day- an added bonus!

    We are thrilled with our renovations and would encourage anyone considering to renovate or under go additional building to contact Cossie Builders. You can see for yourself how professional their outfit is.

    We, without reservation, highly recommend James and Mandy and would have no hesitation to seek their services again.

All work was completed to a very high standard with great attention to detail. Mandy and James managed the whole job very proactively, with great communication throughout, and stayed right on budget. Excellent value. Sensitive to working with two young kids in the home at times, and nothing was a problem for them. "

    "The wonderful service we got from Cossie Builders began with a friendly, welcoming conversation with Mandy, a visit from James and his plumber, and then a very comprehensive quote so that we knew exactly what the project would cost us. James and his team turned up on the anticipated day and it was a pleasure to have them around and to watch them transform my old bathroom into something to be proud of. I have no reservations about recommending Cossie Builders."

    "Our experience with Cossie Builders was unlike anything we had experienced before. From the outset we were impressed with the thoroughness of their quote and the obvious effort taken in preparing it, which was driven by the extensive consultation process. Once on site James and his team were always courteous, punctual, tidy and respectful of the family life that continued in the house. The communication from both James and Mandy enabled us to keep fully up to date with progress and any changes to the original agreed details. The project was completed on budget and on time with minimal fuss. The quality of the workmanship was excellent. We love our new kitchen and we look forward to Cossie Builders returning to help with the next stage of our renovations."

    "Cossie Builders put in a fence around our fish pond, we decided to fence it even though it is shallow and doesn't fall under the swimming pool fencing act. Our dealings with Mandy in the office and James onsite were all very professional and timely. The job took 2 days and I was very impressed from start to clean up James was excellent. The finish is so much better than I expected, I love the way the edges of the handrail and posts are all smoothed off and not sharp. Having a handrail for our steps incorporated into the fence was a stroke of genius,and something James suggested.

    We have had a number of positive comments about the fence which surprised me as its just a fence but goes to show that attention to detail and craftsmanship of even the little things do get noticed. We will definitely be recommending Cossie builders to our friends and hope to have them back to quote on our extension soon.

    "Very unprofessional, poor workmanship, leaving us with extra costs, hiring builders to fix their mistakes. Cossie Builders did not complete the job they had agreed too. I would recommend steering clear of this company, we already spread the word to others as well.
    We engaged Cossie Builders to subcontract a new roof and replace all rotten soffits, weatherboards, and put new flashings in before the house was being painted. At the time we stated we wanted all the rot removed and would be prepared to pay any extra costs if needed (and we did pay for some)

    They however missed some of the rot in the soffits and weatherboards. Two independent builders confirmed it was rot (Cossie Builders claimed it was not rot).

    As we had already paid, Cossie Builders said if they were to come back, it wouldn't be until 4 months which was far too late given we had the house painters coming. We then had to find another builder at short notice to fix (at our cost) what we had hired Cossie Builders to do.

    The quality of the workmanship was also negligible, with beading not quite fitting (the other builders also commented on the poor quality).

    In addition to this the roofers that Cossie Builders had hired for us, were late and the roof was also left in a substandard condition, with water running back over the house with insufficient flashings. The Roofer (who was hired by Cossie Builders!) said it was not his issue and it should have been addressed by Cossie Builders (building up support before the roof was placed on). As Cossie Builders hired the roofer, they should have been talking to each other. As the new roof is up,it is too late too fix. We are left with water running back over the house and we are left hiring someone else to fix the problem.

    Cossie Builders also tried to bully us into paying early (claiming as we were paying by cheque it needed clearing time – which is not a legal requirement).

    This whole thing has ended up being a very costly and unpleasant mistake for us and again recommend strongly to steer clear of them.
    James and Mandy responded:
    "Cossie Builders completed the original job on time and on budget as per the quote. The quote clearly stated that 35m of new soffits and 10 days of labour had been allowed for. When the original job was completed, Janet and Gary were so pleased with our quality of workmanship that they asked us to perform some additional work for them. Gary was very happy that we had provided over 35m of new soffits for the price of only 35m. We had some time before the job for the next client was due to commence so we were able to accommodate their request and perform some additional work for them. Janet and Gary then asked us to perform further additional work for them however we were then due to start the job for the next client so we explained that we could provide them with a quote for the further additional work however we were fully booked for work for the next 4 months. Gary bought it to our attention that he thought that 1 weatherboard had rot in it, we immediately left the new job and returned to double-check it and deemed that it was not rotten. Cossie Builders obtained the second opinion of another qualified builder for Gary, who concurred that the 1 weatherboard in question was not rotten. Gary said he accepted this. When Gary bought it to our attention that the thought that 2 soffits had rot in them, we reminded him that we had already informed him that 1 soffit was touching a live power line and due to OSH regulations we were not able to replace that soffit for him while the power lines were live. Gary said he accepted this. The 2nd soffit in question was also bought to our attention after we had already started the job for the next client. We reminded Gary that we had already provided him with over 35m of new soffits at no extra cost and that any additional work can be quoted upon however we were fully booked for work for the next 4 months. At the time of the job, Cossie Builders was not able to see that this 2nd soffit was rotten due to the difficult location of it and the paint on it. Cossie Builders obtained the second opinion of a professional painter for Gary, who explained that some rot cannot be seen until the timber is fully stripped back. This rot had not been found until Gary\'s painter had fully stripped back this 1 weatherboard in question. Cossie Builders explained to Gary that when 10mm of rot is found in 1 weatherboard then a professional painter would cut out the 10mm of rot, bog it up, and re-paint the weatherboard. It was explained that this is a more cost effective solution rather than replacing the entire weatherboard. Gary agreed with this. Gary was trying to keep costs to a minimum and asked Cossie Builders to re-use the original beading from his house. Cossie Builders did so wherever possible and advised Gary that some of the old beading could not be re-used. Gary insisted that the old beading be re-used so that he could save money. Yes, the roof was late as it was not able to be laid during the ongoing torrential rain. Cossie Builders explained to Gary that it was best that the roof was laid during dry weather. Gary and Janet did write a letter of complaint regarding the roof as they were concerned that the roofers had left mud from their boots on some of the screws on the roof. Cossie Builders takes all complaints very seriously no matter how small and explained to Gary and Janet that the next day of rain would solve that problem for them. Gary did complain that 1 rivet was missing from their roof and Cossie Builders installed the 1 rivet as soon as informed of this. Gary and Janet did complain that the water from their roof was dripping down the outside of the flashing. We sent our roofing subcontractor JB Roofing around to the site numerous times to solve the problem. Cossie Builders also returned to the site multiple times to see if the problem was building related and it was not. JB Roofing reported that there was no fault with the roof or the flashings, that the roof was not leaking, and that the flashing was doing its job by keeping the water out of the house. JB Roofing provided Gary and Janet with their roofing warranty. Cossie Builders have also offered to provide a second qualified Roofer to assess the situation and advise on it however Gary and Janet are still considering the offer. The last that Cossie Builders knew was that these professional assessments were accepted. This was over 3 months ago. Of the 7 invoices that were issued to Gary and Janet, 3 were paid late, 2 were missing signatures, and 1 was missing the GST amount. The very first payment was 8 days late. Cossie Builders found out yesterday, when this review was posted, that JB Roofing had advised Gary that his roof needed building up support before the roof was placed on. Neither JB Roofing nor Gary and Janet had informed Cossie Builders of this advice prior to reading it in yesterday\'s review. It came as quite a shock for Cossie Builders to hear second hand through this review that there were issues 3 months later. Cossie Builders has spent the last 24 hours trying to contact Gary and Janet to meet with them in person, to view the problems, and to rectify them. Our phone calls and emails have not been replied to. As our other reviews and the testimonials on our website will show, we truly are very honest professionals with exceptional quality workmanship and excellent customer service. Now that we have finally been made aware that there are problems we very keen to resolve them for Gary and Janet. We would really appreciate the opportunity to rectify the matter. "
