“I am still quite amazed by the whole process to be honest.
We had a problem and through research we established that soil stabilisation and injection was a very good option.
We asked the two main companies and some others for quotes. S___ came out and was very straightforward to deal with.

The quotation was very competitive…
Then another ground engineer and two others came out – from start to finish these guys were unbelievably professional – honestly they could not have done enough – what a process!

They lifted the floor slab 60mm and we have gone from having a major problem to having relatively level floors again.
Mainmark – your staff are an absolute credit to you. Every guy who worked on this and S___ – absolutely brilliant people!

Thank you all!”

James, Ashton-under-Lyne, Greater Manchester. November 2021

“This 100 years old house was showing signs of subsidence and with a new loft and ground floor extension due to start soon, I needed a strong, safe foundation before anything else. After few quotes from builders (standard underpinning) and another company using similar technology, I have decided to go ahead with Mainmark. Starting with the (free, unlike other competitors) visit of their surveyor A_______, and ending with the actual work, it was a pleasure to deal with such a professional company. All appointments were kept and the work was done perfectly. It was amazing to see how the whole house was slowly moving in increments of 0.5 mm, always under the laser control equipment. D___ was very polite and showed an in-depth knowledge of the technology having worked on 3 continents with over 10 years experience in this field. I have no doubt that this house will be up for another 100 years.”

Minica, Surbiton, London. October 2021

“Excellent Service – Staff friendly and helpful, clearly explained the process, left area having explained all they done, clean and tidy, WOULD HIGHLY RECOMMEND”

Michael, Kingston, London. October 2021

“I recently had some work done by Mainmark, everything from start to finish was excellent and carried out in a professional manner. I would certainly recommend them.”

John, Ashton in Makerfield, Lancashire. October 2021

“1960s house concrete floor settlement. Stabilised and raised 30mm at worst point. A great experience from first contact to work completion. The staff are all polite, helpful and prompt to respond to any questions. The surveyor was very thorough and gave a detailed report and quote in a matter of days. The on-site team were well organised, worked quickly and carefully. There was minimal impact to the wooden parquet flooring ahead of its planned restoration in the coming months. Booking and paying for the deposit and final payment was very easy via secure online web portal. My job has been completed by Mainmark and I still haven’t heard back from another company that I approached at the same time! Very happy to recommend Mainmark.”

Matthew, Orpington, Kent. September 2021

“We would highly recommend this company in every way, as they keep you updated on each part. The team that was run by L___ were absolutely amazing 5 ⭐️ ⭐️⭐️⭐️⭐️”

Eddie, Liverpool, Merseyside. August 2021

“We are pleased with Mainmark Company from the beginning to the end of their assessment and work. We had few quotations from other firms but Mainmark was very competitive and took us very serious. We had very bad experience with another competitive firm who let us down on many occasions. The work was done on time and the team which was led by D____ was professional, helpful and explained the procedures to us. They cleaned the site after they have finished and the whole procedure was not stressful as we expected. We would definitely recommend them and never regret it.”

Milad, Sandhurst, Berkshire. July 2021

“A superb service. The response, following my enquiry, was immediate and the work was completed on time and to a very high standard. Highly recommended.”

Peter, Washingborough, Lincolnshire. July 2021

“Your Team have just left site following a very productive days work. I write to say how impressed we have been by the diligent, professional and courteous way in which the project was conducted. Your operatives under the eye of T___ are first class. In addition we were very pleased and impressed with the professional advise negotiated with the insures Subsidence Engineer in the forming of a contract by your technical rep K___. In general terms a very satisfied customer.”

Robin, Cranleigh, Surrey. July 2021

“I cannot thank M___, D__, J___, and J___ enough for a brilliant job they did on my conservatory. It is amazing to watch the floor rising as soon as the resin as it’s being injected. From the time i contacted Mainmark to completing my job was just a few weeks. J___ and E_____ and S___, kept me well informed about any concerns i had without trying to sell me anything i didn’t need. I would definitely recommend them to anyone, whether its a homeowner or a massive company. They are very professional in everything they do, but also care very much about their work.
Well done to all the team. I cannot thank you enough.
Very much appreciated.”

Valerie, Glascote, Staffordshire. July 2021

“I would just like to say a big thank you to all your team involved, particularly S___ who I met and Mark who my husband met on the day of the work. The company has resolved a potentially serious and expensive issue with our property in a professional, timely and cost-effective manner. I would have no hesitation in recommending Mainmark to anybody. Thanks Again”.

Andrew, Sutton-on-Hull, Yorkshire. July 2021

“After a thorough investigation by one of your civil engineers, a team turned up early to start work. Furniture was carefully moved, carpets lifted and preparations for the job took place. I was horrified by the foundation cracks and gaps between skirting boards and foundations but was reassured by team members that this was not unusual. Drilling and filling took place and to my amazement the foundations were levelled and stabilized and looked so much better. Carpets were re-laid after measurements were taken and the furniture replaced. All-in-all a thoroughly professional job done by an efficient and friendly crew. I could not have asked for better service.”

Derek, Swanage, Dorset. June 2021

“I cannot praise Mainmark enough!! I had movement on my 11year two storey extension and after reading up about this resin injection method I was hopeful of not only stabilising the ground but hoped to get it back up to where it was or very near. So the first company I came across was another ground engineering company based in the UK, and the first initial connect and site visit seemed all good, having not dealt with this situation before I had nothing to compare to. But now having came across Mainmark, due my patience running out with the other company due to their unprofessional attitude when I said i wasn’t paying £12000!! Which swiftly went to £6500 (special price) and they failed to complete a ground test due to their lack of appropriate equipment, amateurish to say the least, they were to send someone else to come and do a “proper” ground test, I’m still waiting 8 months later!! So like the other company, my initial connect with Mainmark was all good, very pleasant on the phone as they should be, organised a site visit very quickly, S___ came to my house inspected it told me what was involved explained things in an easy understandable manner, and gave me a very good price. So then got a date for works to start, D___ and P___ were the engineers who came up to do the the job, very nice and pleasant, and told me they were more than happy for me to watch them at their work and they explained everything they were doing as they proceeded and kept me informed all the way! The guys really did take pride in their work, and you could see they really did get satisfaction from their work, it was great to watch them happy at their work!! So in the end the guys got my property pretty much back to where it should be and I Thank them very much for that, my mind now at ease!! And and final Thank you to E_____ as well all the guys at Mainmark for being very professional right from the off, I do appreciate it guys!!!

Still waiting on the other ground engineering company to get back to me for that ground test!!”

Frank, Glasgow, Lanarkshire. June 2021

“I am very impressed with the work, geopolymer resin injection at my property. The work was completed on time and to my satisfaction. I would recommend Mainmark to anyone who need stabilising of the foundations of their property.”

Raymond, Haringey, London. May 2021

“I cannot recommend this company more highly. K___ carried out a survey on my conservatory as I was concerned it had subsidence. He surveyed it twice as on his first visit he said the ground needed to settle before he could tell and on his second visit he said the movement was minimal and suggested that I monitor it for a few more months as there may not be any further movement and said he would visit again to check. I have had some bad experiences with companies carrying out work in my home and it is refreshing to find a company with integrity, one which does not carry out unnecessary works purely for monetary gain. Again I cannot recommend Mainmark more highly.”

Paulette, Spencers Croft, Harlow. April 2021

“We just had S___ round to assess some worrying cracks in our walls, and he was great. He did a thorough assessment of all the cracks and the surrounding areas, took measurements of changes in the floor levels and walls, and made recommendations on what the causes were plus how to tackle them – all at no cost to us. Unfortunately for Mainmark this meant that there was no work to follow up on as the issue was not subsidence, but I really appreciated S___’s honesty and integrity. As a bonus he was also on time and a thoroughly friendly chap! Would highly recommend, and in fact already have done to a friend who also has alarming cracks in her house! Thank you!”

Claire, Greater Manchester, England. April 2021

“Very happy with the results. Mainmark were very professional from start to finish. The guys on site were polite and kept us informed along the way. To see it happening in front of your eyes is mind blowing. Can not recommend enough. Best money I have ever spent.”

Lee, Spencers Stirchley, Birmingham. April 2021

“Having found myself in a very urgent and awkward spot with some structural issues Mainmark were miracle workers. They were efficient, understanding, easy to deal with and cost effective. I could speak more highly of them – they are a very impressive team who made a really tough situation manageable – and with ease.”

Leo, London. March 2021

“I completely agree with other reviewers – they seem to do their best to give you good sound engineering advice, even if it means that you spend less money with them. Our visiting engineer, K___, was extremely knowledgeable and commented on many aspects of engineering-related issues with our house, before eventually recommending Mainmark’s services for just one relatively small area. Their quote was very reasonable too. Haven’t had the work done as yet – watch this space!”

Dan, London. March 2021

“Mainmark did an excellent job for me – lifting my extension back to where it should be. Everything was very well organised, and the work was done quickly and efficiently, with the minimum of disruption and mess. I would thoroughly recommend them.”

Simon, Guildford, Surrey. February 2021

“I approached Mainmark UK in September 2020 after requesting a quote for their Teretek Resin Injections, K___ visited the property and greeted us with respect and kindness. After explaining what their injections would do he sent us a very reasonable quote for the works to be done. After getting the money together we called mainmark on site to do the works, the engineers were fast and efficient and the effects could be seen almost instantly. Compared with regular underpinning this method is really fast and easy, Not to mention the immense cost savings compared with Geobear and a 20 Year Warranty. You can’t go wrong.”

Harjap, Romford, Essex. February 2021

“The works at the property are now completed, flooring etc all sorted out so the tenants should be pleased. The cracks will need to be filled and decorated, probably give a couple of months to allow for any slight movement.

Thank you for your assistance today, much appreciated! Well done guys great job.”

M_____, Rayners Lane. February 2020

“Good assumption that we are pleased with the work and the result. Outstanding service undertaken with a team who seem to get satisfaction at doing a worthwhile job where the results are immediately clear. Our sincere thanks.”

Alan and Chrissie, Lymington. February 2020

“Many thanks for your completion works report. We are very pleased that the results are positive and have achieved the required stabilisation of the ground to proceed with the roof extension.

May I take this opportunity to compliment you and your team on a highly professional and exceptionally conscientious process of working on this project. The team on site, lead by P___, was a pleasure to have in the building, their process was at all times careful of our working and living environment but also clearly intend on achieving the very best results. At one point P___ said “I treat the work as if it was my own home”. This was felt and much appreciated by us. Please do tell the team that we were really happy with their work throughout.

I am certainly happy to recommend your services.”

Melanie, Hoxton. January 2020

“Thank you for doing the work. Please pass my gratitude on to the Engineers and D____. They were all very helpful and polite. It was nice to deal with you as a company. I also have a structural engineer who is waiting for me to personally give him feed back on your company and works carried out as he has a list of clients who need your services.
Thanks again to you all.”

Keith & Roz Nuneaton, Warwickshire. July 2019

“I’d like to compliment T__ and his colleague (I’ve forgotten his name unfortunately) on their personable and professional approach to the work. It’s not often you get to say it was a pleasure having tradesmen wandering around your property. They discussed all the options, pros and cons with me and made sure I understood what could be achieved. I felt completely at ease asking them the most basic questions. They even managed to use the gaps between paving slabs to minimise the damage caused by drilling.”

Peter, Wakefield, Yorkshire. June 2019

“Everyone was absolutely brilliant, I am so pleased. The crew arrived and worked very hard- there was no messing about, they got straight on with it. I want to thank everybody involved from start to finish.”

Brenda, London. May 2019

“Please pass on our thanks to your team who were very professional and approachable throughout.”

Robert & Christine, Chelmsford, Essex. November 2018

“Just to let you know that M___ and the team were great and had such a good attitude towards their work and everyone around them. There were plenty of builders and activity on both sites. M___ took all of it in his stride and got on with the work with the team in tow.
Firstly, please forward on my personal thanks to the team. Also, could you let management know that their hard working ethos and professional (cheery) nature are a credit to the company.
I will be recommending Mainmark as the go to company to fix subsidence/heave issues.”

Shazad, London. November 2018

“Very pleased with the workmanship and professionalism of all the team on site.”

David, Chelmsford, Essex. September 2018

Robin, Knutwood, Diss, Norfolk. May 2018

“I’m very happy with the results! Exceeded my expectations. Thanks to you guys. Have a great weekend!”

Eddie, Macclesfield. August 2017

“This was a complex project and we had difficulty finding a contractor that would commit to lifting the floor. Mainmark was the only company that would do so. The Mainmark team engaged with us from the early planning stage and was very knowledgeable. The project went smoothly and finished on time. I was very impressed by their professionalism and couldn’t be happier with the outcome.”

Dave, Southport. July 2017

“It was fantastic work done. We are are happy about work.”

Murugan, Orleigh Park, Newton Abbot, Devon. June 2017

“Great service, super job done!”
