What clients say about us

 "Mr. McConkey's experience and knowledge  was critical in obtaining the town and state septic system permits I  needed to proceed with the sale of my property in Freedom, NH. His  design of a new septic system for my small lot considered all town and  state regulations, possible variances thereof, on site testing,  addressing neighbor concerns, and included representing me at town board  hearings. He produced professional work in the short time available  and I'm happy to recommend him."

 "We are in the process of having our septic  system replaced and Mr Mark McConkey is our agent  as Septic System  Designer. He has been professional and timely in updating us on the  requirements of the New Hampshire Department of Environmental Services  for subsurface sites. In addition to designing the system, he also  coordinated the process of having it presented to the NHDES for  acceptance for our site. He made the process go smoothly and easy for  us. We are completely satisfied with the outcome and acceptance of his  design by the NHDES. Thank you for all your good work for us."

 "We were selling our house and had a  closing date that we had to meet. During the buyers inspection it was  discovered that our septic system was in failure. We were referred by  our realtor to Mark McConkey. We informed Mark of our situation and the  time frame that we were under in order to sell our house. He came to our  house right away, decided what was needed and got right on it.  Unfortunately, during his surveying process, Mark was attacked by a  swarm of bees. He had a reaction from the stings and ended up in the  hospital. Through all of this he still made sure our deadline was met.  Mark and his crew did an excellent job. We could not thank him enough  for all that he did for us."

 "Recently we moved our mobile home onto a  private piece of land. We hired McConkey Construction as our General  Contractor to handle a lot of the site work.  Because we are from out of  State, we needed a company we could trust in getting the work done  correctly.  The Company’s knowledge and professional crew solved  problems that arise. The Company provided the test pit, septic design  and installation, driveway excavation and cement slab. The crew worked  well with other contractors on the job. We were very pleased with  McConkey Construction Company and appreciate all the work the crew put  into our project. This company went above and beyond to get this done  for us.   Thanks again for all your hard work."

 "I Contacted  Mark McConkey to quote me a price on a septic system installation.  After reviewing the design plan, Mark found an error in the layout and  had it corrected at no additional cost. His workmanship was  professional, fairly priced and completed on the agreed time.

I would highly recommend Mr. McConkey for any septic related project."

 "Mark provided expert service for me the  next day from talking with him and completed a detailed report which  explained my septic system. Beyond this job, I've known Mark for over  ten years, and have always known him to have the highest ability and  integrity in his work. I recommend anyone needing septic work performed  to hire Mark."

 "When I decided to place my lakefront home  up for sale at the end of May this year, my local realtor suggested that  I expand my septic system.  While the reasoning for this made sense, I  dreaded the idea of a major project and the accompanying headaches that  would involve.  Fortunately, my agent strongly recommended McConkey  Construction for the job, and I heeded his advice.
            Mark McConkey designed and installed the new system, and I cannot overstate how pleased I was with the work.
             Mark quickly and efficiently secured the necessary permits for the  proposed plan, provided me with a clear and precise estimate, and began  work on time as promised.
            His crew was outstanding; a  friendly and courteous group of guys with great attitudes and work ethic  despite the oppressive heat and blackflies.  A refreshing change from  past experiences.  While excavating the site, they took special pains  not to disturb my extensive landscaping without my having to ask.  And,  upon my request, they even delayed reseeding the sod until I would be  back from a business trip and able to water properly.
            In  short, the septic design and installation went seamlessly, the entire  McConkey team was a pleasant bunch to have around, everything passed  inspection, the project stayed on budget, and the house sold the first  week on the market.  There was absolutely no reason for my initial  misgivings about undertaking the expansion of my septic system.  I feel  fortunate to have known to hire McConkey Construction for the project.

 We are writing to send our deep and sincere  appreciation to McConkey Construction, Mark McConkey, for all of your  work on our new septic system. We cannot imagine finding another  professional who was so thorough, communicative, helpful, and a pleasure  to deal with.

We had a failed septic on our waterfront property  in May 2021. We looked at a number of designers but McConkey was clearly  the best choice. The price was very fair and the knowledge of the area,  our specific condition and a promise of a quick design time frame made  our decision easy. McConkey came through as promised with a design in  the time frame promised and obtained State Approval and Permit within  days after the design was completed. This was months ahead of when  others thought they could finish.

Due to our scheduling  constraints and prior commitments we made we did not hire McConkey to do  the install. This proved to be a mistake as the installer had a number  of issues with his workload and was challenged by our difficult site.  Due to a number of circumstances and unforeseen subsurface conditions  the installation took much longer than promised and the system was not  installed per the plans. We became very frustrated and quite desperate  as we were now months without a working septic. Mark came through and  was able to accurately document the conditions, gave us professional  expert advice and worked closely with us and the State to solve the  issues and get the system installation completed and approved by the  State. Mark was always professional, was quick to return calls, gave us  needed help and guided us through the State permitting needs, rules and  requirements. It was also clear to us how much respect the State has for  Mark and his company.

We now have a new working, fully permitted  waterfront septic thanks to Mark and McConkey Construction. We would  highly recommend Mark and his company to anyone that needs septic design  and installation.

" As a Realtor with one of the largest Real  Estate brokerages in the state of New Hampshire that works with buyers  and sellers from all over the Northeast, specializing in property in New  Hampshire's White Mountains and the Lakes Region. It is essential that  are partner vendors have a commitment to excellence and exceptional  service as well as accountability and professionalism. I have been  working with Mark McConkey for over 8 years in every capacity from  digging a test pit to complete septic designs and installs, site  assessments as well as random issues of tree roots in septic lines,  docks and all permits for each job. Every situation starts out the same,  once the client has a request for a service, the phone call to Mark is  placed and the process begins. Mark promptly answers the phone, the task  is assessed, with in a 24 to 48 hour time line, Mark and his crew are  on the site in person for an evaluation of the job, followed by an  emailed quote outlining the fees, the amount of time and job cost. The  dates are set and the task and job costs are completed on task on time  and on budget. Depending on the year Mark and his crew handle 5 plus  jobs a year for clients of Nicole Martinez Homes of KW MTRO, in addition  the homeowners and or buyers of these properties continue utilize the  services of McConkey Construction for future jobs and do so with  confidence.  Mark and his crew are prompt, attentive and very  trustworthy. Mark's family has made this community their home and work  hard to ensure that each client is fully satisfied. Mark and his family  have been in this community a long time. The benefit of that to his  clients is that takes the guess work out of many situations, since he  knows the history of many properties and who has been there before him  as well, town codes and regulations as they have evolved over the years.  Mark is a member of the NH legislature and works well with all of the  town offices to get permits, meet with the planning boards and code  officers regarding each job. The best news from McConkey Construction to  date is, that he is now passing his expertise on to his son Dale who is  working in various capacities in the firm, alongside is long time crew  member Toby. These gentleman are prompt and professional and represent  McConkey construction well. My clients own homes and land valued from  $20k to $800k and each time we have entrusted their property to McConkey  Construction."
