Hear what our clients have to say.

Bob: Waban, MA

Mark Kaferlein, owner of Kaferlein and Son, LLC, brings a rare combination to the role of General Contractor: he does exactly what he says he'll do, and he brings the project to completion on time and on budget.

Mark’s work is impeccable.  He finds solutions to problems that inevitably arise in every construction project.  His subcontractors all possess high character, good work ethics, and loyalty to Mark.  They are nice people to have around.

After completing several projects with Mark and his company, he has become our “go to contractor”, and a good friend.

Cyndi: Belmont, MA

We completely renovated the first floor of our 1920’s Colonial including a new kitchen, bathroom, and living room. It was a large and complex project and we couldn’t be happier with the results. Our space has truly been transformed! Mark and his team were terrific to work with during the entire process.  Mark was a great communicator and kept in touch on a regular basis so there were no surprises.  His team, including sub-contractors, were all friendly, knowledgeable, and took a lot of pride in their work.

Lauren and Mike: Billerica, MA

We hired Mark and his team to completely renovate our kitchen and foyer area a few years ago and are very happy with the finished product.  Mark and his team were great to work with.  They were always on time and communicated with us throughout the project so we knew what to expect every step of the way.  Mark is very conscientious, hard-working, and produces excellent results.  When I tell people I had a fantastic experience renovating my kitchen, they are surprised because I have not one negative thing to share.   I only have great things to say about Mark and his team and highly recommend them. 

Kate: Waban, MA

My husband and I have used Mark Kaferlein and his team for two projects on our own residence:  a complete rehab with updated systems and baths, plus floor plan modifications, and a few years later, a large kitchen/garage/deck addition.  We are about to begin another addition on our home using Mark. Last year we teamed with Mark to rehab a 100+ year old Victorian for resale, with a complete renovation, updated systems, changes in floor plan, and new kitchen and baths.

Mark and his team at Kaferlein and Son are the best contractors we have worked with, and our continued use of their services is a testament to this.  Mark’s costing skills and ability to stick to budget are unmatched. His quotes are far more accurate than other contractors, who often underbid to get the job, then add costs later.  He and his team have a wide range of skills, from demo to fine carpentry.  More importantly to me as a woman and mother, they are polite, clean, pleasant and even humorous.  They interact with our family beautifully, don’t swear or leave cigarette butts around, and leave the worksite in great condition each day.  Mark is on time each day and with each project.  He explains each phase, and has a nice way of communicating and collaborating on all details of the project as it moves along. 

I recommend Mark Kaferlein and Kaferlein and Sons with the highest of accolades.

Jill and Rob: Billerica, MA

In 2012 we hired Mark to renovate our kitchen and downstairs bathroom.  Mark was knowledgeable, thoughtful, and extremely hard working.  He took our basic plan and was able to see any potential issues in layout that we may not be happy with in the long run. We loved the finished product, and if we had to do it over again, there is not one thing we would do differently.  After listening to several other renovation stories, I felt like we hit the contractor “jack pot”!

Mark and his team were on time, clean, and a pleasure to work with.  Workers came when we were told they would come, and the whole process ran smoothly and efficiently.  We are about to start a renovation of the upstairs of our house including two bathrooms.  When we started planning the project there was no doubt in our mind that we were going straight to Mark.

Tracy and Mark: Belmont, MA

We hired Mark in July 2014 to do an extensive kitchen renovation with a small addition. Mark is extremely professional. He was always willing to explain, in detail, each step of the process as well as answer ANY question that two adults with no construction experience threw at him. We were so impressed by Kaferlein and Son’s work that we kept adding projects. We have complete trust in Mark and his team. Their work is amazing, they have transformed our 1928 home into exactly what a young, busy family needed. We highly recommend Mark and his team of craftsmen. We will never invite another contractor into our home!
