So Mantair recently fitted a conversion kit to my spetic tank to comply with 2020 binding regs. A VERY professional service from start to finish. Matt visited and did a site visit initially and then Steve & Sutton run the professional groundworks. Their communication was excellent , they handled all the necessary paperwork, If you are looking to have any septic tank compliance work done or even a new tank, Look no further Mantair are the only option!
Totally professional, exceptionally high standard and quality of work & amazing workers. Courteous and efficient, friendly and approachable staff. Have recommended to neighbours
The Mantair team were out installing a new sewage treatment plant for us this week to replace an old system which was beyond economical repair in Boxted, Colchester. From start to finish the company has been brilliant. The office was responsive and informative on all emails when quoting. The lads on site were thorough, experienced and caring when manoeuvring the plant around with everything being left tidy at the end of the job. Their yearly planned maintenance package was also very reasonable which we have taken up. Couldn’t recommend them all enough and look forward to working all at Mantair again on the next project. Many thanks from us all at Property360 Ltd.
Mantair were a great company to deal with from start to completion, fully professional but without the fixed processes of a bigger corporate. The family members were as helpful as could be in setting up the project and tackling some issues which came with our particular situation on the edge of a working farm. The installation team were professional, helpful and a pleasure to work with. The system seems to be working perfectly at less than half the cost of alternative options.Highly recommended!
When most of the world are trying to sell you something you don’t need ,mantair and in particular Kevin are the rare exception. Another company said our tank was non compliant without even looking at it. Kevin however said that it was and even explained why. Good on you mate .
Excellent company. All the team we dealt with were great - The work was done on time, with no mess left and they communicated brilliantly throughout.
From faultless installation in 2024 to this February’s first service, the Mantair Converter has run impeccably - much like the dealings with the company itself.
We’ve recently had a septic tank conversion unit installed by Mantair and we’re over the moon with the unit and the service received.Kevin turned up exactly when he said he would, he was extremely knowledgeable and friendly. He then provided the quote later that day.All of the office team (first enquiry, payment, EA queries) I spoke to were all equally as helpful and knowledgeable.On the day of installation the team were prompt in arriving and cracked in with the job. The hurdles that popped up during installation were dealt with promptly and without fuss. By the end of the installation the weather really wasn’t on their side, however they left my garden as neat as physically possible.Thank you for a brilliant job, we look forward to having you back for our yearly service.
Mantair have been so helpful and professional while working for our clients on our behalf. From our first enquiry and initial meeting through to the completion, you couldn't have been more helpful. All of your guys on site were so friendly and polite, and their workmanship and reinstatement was outstanding. Many thanks to all involved.
Engineer came as soon as possible. Problem fixed in no time at all.Staff at the end of the phone great to deal with also.Excellent from start to finish.
Great experience from start to finish from Mantair installing my septic tank conversion unit.. Good communication throughout, very polite and professional installers. Considerate of my garden, neat and tidy.
I can honestly say Mantair Ltd are an absolutely first-class family run business, from the first contact made to the final paperwork, all members of the team have been professional, efficient and super helpful. Their knowledge and expertise are second to none.The malfunctioning sewage system in place was causing me considerable stress and worry, Mantair from the start took the problem out of my hands, they worked solidly for 2 days to transform the system. Their family values mean you feel you are being treated considerately and individually, not just ‘another job’, excellent service.I cannot thank Mantair enough for the work completed in such a professional manner, I would highly recommend Mantair for any drainage issues.
As our septic tank drainage field had failed we contacted Mantair and their response was excellent. A very informative site visit led us to have a conversion unit fitted to the septic tank with a new drainage field. The work was done on time with minimum disruption to our lives and both the two engineers and the electrician were very pleasant, informative and helpful. Can highly recommend this company based on our experience.
Contacted Mantair around 18 months ago to discuss replacing an old septic tank with a sewage treatment plant. My experience is that Mantair are professional, arrive when they say they will and are always very helpful. Mantair arranged absolutely everything. The work was completed very efficiently, with respect for our property. Had an issue over winter with the pump. Mantair came out quickly and fixed the issue. Just had the first 12 month service. Again, representative arrived promptly and, as always, professional and courteous. Great service!
In my experience it is very hard to find contractors that are trustworthy, reliable, professional, competent and knowledgeable. Mantair absolutely fits all that category! It took me a very long time to find suitable contractors to install my new system. James and all of his staff are an extension of him, “professional”. I’m very grateful to him as he resolved a major issue I had with my old system which was installed in clay soil and no drainage outlet. Now I have a fully functioning system with no issues and I know i will have the ongoing maintenance support for if and when I require my system to be serviced or maintained. Big thank you James I sincerely mean every word!
A fantastic job by James, Sam and Luke. Very professional, knowledgeable and courteous. A pleasure.
The installation went exceptionally well. The planning was meticulous and best of all the two 'Sams' on-site were positive, upbeat, competent and consultative throughout, a credit to their company. The job was completed on time and we are thrilled with the result. They went to great lengths to ensure we were happy with the cosmetic results as well as the technical ones (eg topsoil and re-seeding, matching gravel shades on the drive etc.) A working sewage system, enabling us to enjoy hot baths and flushing the loo without worry! We have no hesitation in recommending Mantair.
In November 2023 we had a Tricel treatment plant installed by Mantair and found them to be excellent in every way. They handled a difficult job on an SSSI site in trying weather conditions. The company handled the permission required from the Environment Agency. Their installers, Ryan and Sam were very helpful and friendly and worked really hard to get the job done. They made a great job of clearing up after they had finished and supplied new gravel for our car parking area and even re-seeded our lawn! We wouldn't hesitate to recommend Mantair to anyone considering a new system, they are a very professional company to deal with. Very happy customer.
After having a problem with my septic tank I gave mantair a call to see if they could help, I spoke to Kevin and we quickly arranged a day for an on site meeting to discuss any works to be carried out. Kevin quickly diagnosed the problem and advised me of the work needed. A very genuine person and company which I have no hesitation in recommending.
Drove all the way from Essex to North Wales to install a new system on my septic tank. Exceptional Service from Sam & Luke. Polite, Courteous, Helpful and Friendly. Nothing too much trouble for them and they left the area they were working in immaculate. Explained to me how the system worked and answered all my questions without me feeling stupid or a bother to them. I can not recommend this company enough - from start to finish from the planner to the installation ABSOLUTELY FANTASTIC. Can not recommend enough. Thank you guys very, very much.
Had a new system installed just a few weeks ago. The discharge pump has failed for the second time. To be fair Mantair got an engineer out on the next working day and he investigated and corrected the issue. Fingers crossed.
Mantair fitted a treatment plant in our septic tank. The service was brilliant from first contact to completion of works. Everyone involved was professional and a pleasure to meet. Would highly recommend.
Superb service in site assessment of our current septic tank and advice after inspection. Kev from Mantair was able to come and inspect the same day we called and the information he provided was professional, clear and very informative. We highly recommend Mantair after seeing work undertaken at a neighbours property and also our direct contact.
Mantair replaced the failing septic tank at our Care home last month. We've been hugely impressed with their service from the starting point of surveying the site and quoting to the stage of installation and completion. We'd like to say a big thank you to everyone at Mantair especially Steve and Ryan who were superb and made the whole experience hassle free for what seemed to us such a massive job.
Mantair are a first class team to work with. We had to replace a failed and shared communal drainage system servicing 8 homes, with a new drainage field and Sewage Treatment Plant. From start to finish Mantair were very responsive, professional, communicative, helpful, knowledgeable and reliable. Throughout, they handled all enquiries from the various homeowners and management team, as well as liaised with all the relevant organisations, building control, EA etc. The quality of work was excellent. It was a large, challenging and complex project to co-ordinate. The installation was delivered on time and the finish even included grass seeding! I would highly recommend Mantair and their team, Matt, James, Nicola, Rowan, Sam x 2 and the rest of the team who helped us.
