Sorry it took me so long to respond to you but I have been sick since I got home to CT on 10/31.
By George
need to know what to do about the exit pipe cover in the yard. it was off yesterday and the open pipe exposed. don't think it will last through the first snow storm. Rest of the basement looks good
By Mike
Great work!
By Mary
I would like to let you know if the system works before finalizing my review, but you can always ask me after the thaw!God Bless!
By Cleston
Thank you for a job well done. We obviously don't know how it will work (because it was completed today) but we have very confident it will work exactly as you explained. We will call if we have any problems but we have a feeling we won't see you until it is time for the yearly check of the system. And again------THE THREE GENTLEMEN YOU SENT HERE WERE WONDERFUL!
By Pauline
The guys that came out to do the job were awesome! They did a fantastic job and I no longer have to worry about a lake in my crawl space! I was also pleasantly surprised with how affordable this was. Thank you so much. I will definitely recommend Northern Basement Systems for anyone needing this type of service.
By RICHARD
MATT, THE TECHNICIAN WORKING ON THE SYSTEM WAS VERY KNOWLEDGEABLE AND THOROUGH. HE WAS ON TIME AS SCHEDULED, TOO. KEEP HIM!
By Edward
I thought the work to install the system was outstanding. The only thing I think could be improved is the finish work. rough cement work and an old piece of wood to support the sump pump drain pipe.
By Jim
The installation crew found a potentially expensive problem that I was hidden behind insulation that I was unaware of. They repaired it at a fraction of what it might have cost had it gone unnoticed.
By Janice
I will be sending an attachment to an Email to Chad to give to Matt.
By Susan
My only reservation was about the placement of the outside drain (I wasn't here for that piece of the job) but my concern was promptly addressed and I anticipate full resolution shortly.Count me totally a totally satisfied customer!
By Ronald
Great job.
By Nancy
This was a very good company to work with. I worked directly with Matt Clark and he was very responsive and accommodating.The only service I had was encapsulation of a basement that has a dirt floor and \"knee walls\" in a seasonal residence. I needed to reduce a very bad humidity problem that developed. The crew did a very good job of leveling the dirt and removing large stones prior to installing the mat and liner. I highly recommend the mat, as it provides an additional layer of protection to support the liner.It has been one week since the installation. Unfortunately, while the musty smell is gone, the humidity problem is still an issue because the surface of the liner is wet from condensation (no pipes are leaking). I believe the purpose of the liner is to reduce, not completely eliminate, the temperature difference that leads to the humidity. So I will use a dehumidifier for awhile and see if that eliminates the condensation problem. If it does, it will leave me wondering whether I spent a lot of money to encapsulate the basement when all I needed was to run a dehumidifier! The basement walls have some foam insulation that runs the perimeter at the top of the walls, but it may turn out that I need to add more insulation. Time will tell - one step at a time!
By Mark
Have a minor concern regarding the \"appearance\" of damp concrete on southern exposure slab.
By joel
i hope you all will come back and finish the bulkhead the chain broke and could'nt finish it. i just hope its not the last i see of you all. your team did a great job they did'nt waste anytime and was very hard workers all of them
By Christopher
The two workers were great. Very nice. Very informative and pleasant. Worked very hard and efficiently. I would definitely recommend to friends/co-workers. Good experience on all levels.
By Angelo
Matt's team came in and did a great job on my garage slab repair. It was professional, quick and clean, couldn't ask for more.
By Vincent
Great workI Look forward to the time that I can come back after a few seasons to confirm the high quality of the work.
By Steven
Very good experience overall. Paul, Matt, Dean were excellent to work with. They were all very responsive to my questions, concerns and needs. I have a bit of a Type A behavior myself so I have or try to have a great attention to detail. So although not required of me it was still in my nature to stay actively engaged with each task as there were alot of moving parts to this project. Despite my nature, all the guys were very professional and aquire excellent customer services skills. Communication although at a high level does still need to be worked on within the company. I did at times get a sense that things about my project were not always being effectively communicated between individuals as I did have to remind people of things at times to make sure we were completing the project completely. The only other thing is for the company to to make sure they discuss, offer, communicate all the different finance options so that the customer knows and makes the right timely choices to avoid extra surcharges, etc. Awesome company and I look forward to working with them again in the future.

Very pleased with installation crew. Very nice, friendly, knowledgeable, professional. Thanks!

The best decision I have made was to have Matt Clark's Northern Basement Systems replace the sump pump in my basement. I have had so much stress lifted off my shoulders since the new pump was installed last February.  You hardly hear it run and it dos a wonderful job.  It has given me the added comfort of having the battery backup to be able to leave the house for long periods of time during a storm and not having to worry that the pump may go out and the pump will not be working. In the past I have had to get the generator going! From the young man that came and did the initial assessment, to the team that came and installed it, I was surprised by their professionalism. Today, the pipes were buried in the yard and you can't even hardly tell where they are!  Exceptional Service!!!  I will highly recommend Northern Basements!!

To: Matt Clark Thank you and your crew for the great job in installing the Basement Waterproofing System in my home.

Thanks again, Joan Bombard

"I wanted to take a moment to thank you all for the hard work which has gone into my basement this past week. I am aware that climbing into dimly lit and poorly ventilated concrete slab for jack-hammering, is not the most glorious work. I commend Daryn, Steve, and Danny for doing this without a complaint. Their professionalism, execution, and quickness of work was pretty amazing considering the laborious task they were undertaking.  Likewise, I would like to thank Jamie in the office for helping to ease us through this process, and Kevin for beginning the whole job. We are looking forward to working with your company and especially Matt in the garage, as he also demonstrated a high level of professionalism when he and Brandon were here."

Dear Mr. Clark, I wanted to let you know how pleased I am with the work you did for me on the week of November 7, 2011. You and your crew were a pleasure to work with. Even when you were not here your lead person was able to explain and answer any questions that I had. Also the place was left neat and clean when you were done. I know it was a lot of hard work, and I just wanted to thank you and your crew. Sincerely, Margaret F. Crocker

"I had a TripleSafe System installed several years ago and couldn’t be more pleased! My property has a very high-water table and the TripleSafe gives me peace of mind knowing that my basement won’t be flooded, even in the event of a power outage. From the initial consultation with Chad, to install, and services with Jessie, and quick response from Irma, Matt and Chris regarding questions or concerns, I’m so happy that I decided to go with Matt Clark’s Northern Basement Systems and highly recommend them!"
Kim M.
Jericho, VT
  Kim M. from Jericho, VT had plans to expand the living space in her home by finishing the basement. There was, however, one thing getting in the way of that expansion: a crack in the basement wall that was, she later learned a sign of structural damage. The basement wall was in fact beginning to bow inwards. A friend of the family advised her to call Matt Clark's Northern Basement Systems, and when she looked us up on the Internet, she found so much information about the problem she was experiencing, that she felt confident about hiring us for the job. In this video she talks about the experience:"They were completely on time, they did exactly what they said they were going to do.They don't pressure you, they don't tell you you need things you don't." , says Kim. "It is just really reassuring because they know what they're doing and you know you are not getting ripped off."

I want to compliment you on your fine staff. The workers were well mannered and very knowledgeable in their jobs... I had questions that they all answered so that I could understand what they were saying and why they were doing what they were doing. I wish more contractors had knowledgeable and congenial workers as you employ. Believe me, I will be singing praises to all that ask and then some. Thank you for all that you and your staff did.

I wanted to let you know that we are very happy with the work that was done on the basement, how quickly and efficiently it was done.  All of the men that were here on those two days and especially the guy in charge were all very pleasant and professional.  I just wanted to let you know that we are very happy with the work and your staff.  When we are ready for the second half to be completed we will reach out to you folks.  Many thanks,  Judi W.

Brian Kiniry was our Sales contact. He was very informative, responsive and patient. We needed to have several different quotes made, as we figured out how to best present our project to put together a grant proposal and to meet the requirements of the Fire Marshal whom we needed to have sign-off on our building permit. Brian was very understanding of our needs, and also very good about explaining the options available to us. He understood the trade-offs we needed to make and helped by giving accurate information about the choices. Matt Ostrout did a couple of site-visits before construction started, to find any areas which needed special attention. He was very collaborative in his approach and worked with me to figure out the best ways to get foam where we need it to seal and insulate. He also conferred with and worked well with Hunter in the job site work. Hunter continued our experience of getting excellent communication from NB. He is clearly committed to customer satisfaction. He solicited feedback on how things were going and wanted to make sure that we were getting everything we needed to be completed quickly. He and his crew went above and beyond, looking for additional areas in the rim joists that could be filled with foam, for example. Hunter also asked for me to visit the site when needed, to go over questions that had come up. His excellent communication skills made it easy to work out the minor problems that occurred as they do in any project. It was clear that he wanted us to understand what we were getting, and any trade-offs that needed to be made. Along with his crew, Hunter paid attention to the details of installing the WaterGuard drain, the sump pump, the B2B insulation panels, and the rim-joist foaming. Panels were installed straight and tight, with foam in the seams. Top edges were cut straight and level, just where I told them the trim would be installed. Wiring channels were kept available during the foaming of the rim-joists and labeled for the electrician. At the end-of-job meeting, I identified a couple of small issues, and Hunter quickly took care of them. He was consistently polite and attentive to our needs. The job-site was kept quite clean, from the jack-hammering of the concrete floor through the foaming of the last cracks in the rim-joists. The crew masked off areas with plastic to keep foam and intumescent paint off kitchen counters, sinks, etc. We had only a bit of dust to vacuum up when they were done. I had good references from another member of our Board of Directors, who had an equally good experience with NB. I also got a good reference for Matt Clark from someone who knew him from Tri-State Basements. We also found that NB offered the best variety of products and services. This allowed us to hire NB to do the whole package of work, rather than hiring separate contractors for drainage and insulation work. This made managing this project much easier.

We know that our job and our house had been a big complex mess of challenge for Northern Basement. We know you could have chosen to walk away from it instead of diving in, literally, and crawling around to mark our house safe. We are and will remain grateful—and a lifelong reference for Northern Basement.
