Received a prompt response

I received a prompt response to my enquiry and was pleased to have one of their managers visit my site the following week to evaluate our situation. It was determined in my case that the resin injection solution might not be suitable for our particularly situation and a thorough explanation was given as to how the solution might be used, the risks involved and the costs. Whilst we did not use Mainmark, I wanted to commend them for the way they went about dealing with a customer enquiry and their professionalism shown on site. Many thanks.

Great bunch of guys

Great bunch of guys who came to do the work. They shared all information they had about the progress at each step. Work was completed on time and they left everything clean and tidy. Would recommend to others.

Professional, accurate and sound advice

Professional, accurate and sound advice. We asked for a quote and received expert advice which was empowering and all issues were explained so that we could understand exactly what was happening. Excellent communication and follow up from the Engineer. Would very highly recommend this firm.

Honest, professional advise

I had an issue for selling our house. The building inspection pointed out that our foundation had a huge issue, and purchaser demand heavy reduction of purchase price, and we can’t afford that. I made contact with Mainmark just after Easter, response was super fast even it came from their head office at Aussie. Sean from Mainmark Auckland team not only reschedule our appointment earlier, but also, I believe the most important is that gave us his honest, professional advise. He used his special high tech machine (sorry, I don’t recall the name of machine he used) measured the whole house to prove that our foundation is perfectly fine, well settled within tolerance of building code. I used to deal lots of different companies in the building industry, to be honest, there are quite some companies only profit driven and doesn’t care about their customers. Sean and his team at Mainmark certainly is not the case. I would like to highly recommend their service to everyone, and definitely would like to work with them again.

Honesty and integrity

I’ve had to deal with a lot of businesses when undertaking the remedial work on my house, Mainmark was easily one of the easiest to deal with, even during COVID levels 4 and 3 they responded very quickly and booked in a consultation no problem. Barry is a valuable ambassador for the company, he’s friendly, knowledgeable, and communicates clearly. In my case it turned out that my house was not in need of Mainmark’s services, even so Barry took time to share his helpful advice and treated us no different. It’s this honesty and integrity that I’ve found is not always easy to come by in NZ’s construction industry, and will no doubt build Mainmark’s reputation.

We had a great experience

We had a great experience with Mainmark after finding the house I bought at auction had a sunken ring beam and floor levels were all over the place. They fixed the problem, made sure all the windows and doors shut and opened upstairs there was no cracking or damage to the new plaster and paint that had just been applied and they cleaned up so well we could hardly see where they had been. We can recommend Mainmark ground engineering, Thanks

Use these guys!

Had a problem with our driveway cracking – called this company – when he arrived he instantly saw the problem isn’t one that their services can fix, but rather than just say sorry and leave, he reassured us that it wasn’t as big of a problem as we thought, explained why, and told us how to fix it… awesome customer service and honest professional opinion… use these guys!

Great work guys

Mainmark staff were professional from the outset. Communication became an issue with Covid restrictions which were placed upon NZ businesses. I was promptly notified of changes as commencement date approached. On arrival the staff were courteous and professional throughout. Communication was excellent they advised me about conditions which could affect outcome and gave me solutions to enable a satisfactory conclusion. On completion the process and remedies were explained in detail giving great confidence in application process. Great work guys.

Awesome stuff Mainmark!

After having concerns about the foundations of our house we called mainmark and they organised someone to come out the same week. Not only were they quick to help, the person they sent out was extremely helpful. Barry was professional and knowledgeable. He was quick to work out that there were no foundation issues and he was able to tell me what the issues were and point me in the right direction – giving me notes on what needs to be done and how much of it we could do ourselves, making the whole experience very easy. With such knowledgeable, friendly and professional staff I would highly recommend this company. You know you won’t get ripped off and they will make sure you have all the information you need to make an informed decision. Awesome stuff Mainmark!

Nick Binks

highly recommend this Company

Barry is polite, professional, friendly and had kindly given us advice on how to fix our problems, we would highly recommend this Company.

Andy Pang

Gave me clear instructions

I was worried that my house was sinking so called Mainmark on a recommendation. Barry came out within a couple of days and did a site inspection and drawing. It was awesome to be told that my problem was very minor and at this point I don’t have to take any action. He gave me clear instructions about what to look for that would indicate further sinking. It’s great to have peace of mind but also to know what the solution is should things progress.

Candice Murray

Very professional team

Very professional team. Minimal disruption to us while the process was underway, and all over in 2 days!. An amazingly cost effective way to stabilize our biggest asset, assuring our peace of mind for the future. Couldn’t recommend more highly.

Ure Abodon

Helpful advice

Barry arrived at the site on time, quickly assessed the issues and provided helpful advice during his on-site visit. We will be back on touch when the drainage work Barry advised be carried out ( to stabilize the surrounding ground prior to Mainmark doing their work) has been completed.

Devon McDonald

The experience was remarkably good

The experience was remarkably good and solved a major problem on my sinking driveway. The three guys who arrived to install were absolutely super— efficient, creative in the face of a few unexpected problems, friendly and tidy. I couldn’t have asked for better.

A thoroughly professional job

A thoroughly professional job carried out very efficiently by a great couple of guys. Exceptional value for money – about one third the quoted cost of under-pinning. Excellent results achieved in only a few hours. I happily recommend Mainmark for foundation / floor recovery. 5 stars!
