Client Testimonials

We value customer satisfaction and quality work above all else. Read testimonials for some of our happy customers and learn a little more about our home building process from their perspective.

“When we decided to re-build my in-laws house so my husband and I could move in and take care of my 88 year old father-in-law, we had special requirements which had to be met. Custom Concepts worked with us from the very beginning, helping us to plan and design a home where we could all live together yet have our own space. Their creative design ideas were instrumental in building a home that is not only beautiful but extremely functional for our situation. We found the workers to be highly-skilled professionals who pay close attention to every detail and their work is impeccable. We would not hesitate to use Custom Concepts again in the future and have already recommended them to our family and friends! Thank you again Custom Concepts!!”

“Isaac Low and his team did a great job on our kitchen & bath remodel. Our tired old 1970’s kitchen and ancient bathroom is now a modern showplace! Isaac and his team did the demolition of the old kitchen and bath, moved a sliding door to make room for a repositioned refrigerator, re-tiled the floors and bathroom walls, installed new cherry cabinets, and redid the walls. One of our favorite parts of the project is a custom bay window over the sink. The stone counter extends all the way into the bay window and now the kitchen seems bigger than ever. The house looks great both inside and out.

The work was very high quality. Everyone arrived when they were supposed to.  The project was completed on time and on budget. The entire team was professional, and the job site was always neat and clean. I enthusiastically recommend Isaac for your project – you’ll be glad you selected him!”

“Isaac Low of Custom Concepts oversaw a major addition to our home: adding an entire second floor, including a full kitchen, 1 and 1/2 baths, living, dining, bedroom, studies, even a chapel. We worked with him from the beginning when he steered us to an architect who executed well on our ideas and wishes.

At the start of the project, Isaac provided us with a detailed cost estimate of the project and then worked with us to fine tune it to meet both our needs and our budget. Throughout the course of the project, if an extra expense arose, he would inform us of it so that there were no surprises at the end. His estimate was very close to the final cost — differing primarily as a result of upgrades that we decided to make along the way. The workmen that Isaac used did their jobs well, and we are very pleased with the result. There was good quality both in the finishing and in the underlying construction. A notable quality of Isaac’s company is that all of the people who work with him or who are recommended by him are exceptionally pleasant to work with and demonstrate high levels of integrity and care for their customers. Our son and his family, including small children, continued to live in the lower portions of the home as the work was done, so the quality and manners of the workers was very important to us.

Isaac himself is a delight to work with. While he did not always respond promptly to my occasional anxiety about progress, he did always respond promptly when there was a real need. Since the project was completed, he has been responsive to requests for fixes to small things that have cropped up, getting them attended to promptly without cost to us. It has been evident throughout the project that Isaac’s primary concern was doing a good job for us.

Over the course of our work together, I believe that I’ve come to know Isaac’s character and ability well, and I trust him completely. That’s the highest praise I can give. I would certainly hire him again and have recommended him to personal friends.”

“We have been in our new home for almost two years and have been very pleased with our home and our relationship with Isaac and Custom Concepts. From the beginning,  Isaac was a gentleman in all respects. He was very approachable and willing to work together with us in order to make our home the place we wanted it to be.  He has been available to help us whenever we have had questions or concerns pertaining to our home. In addition to offering great customer service, Custom Concepts offered us a home that was built with the utmost detail and craftsmanship. Every time that someone enters our home they comment on the beauty of the woodwork and the attention to detail throughout the house.  We love our home and have been very pleased with our relationship with Isaac and Custom Concepts. In the process of buying our new home, we also began a new friendship with Isaac. In working with Isaac you will find an honest businessman and great craftsmanship.”

Isaac Low was one of the chief builders of the Wyndstone neighborhood homes.  As one of the builders he is intimately familiar with the construction.  We have worked with Isaac on other projects at our home including building a room over our garage and our front porch construction.  You will not find a better builder to work with.  Isaac has the highest integrity and workmanship.  If you call him, you’ll get a call back; he’ll show up on time and complete your project in the planned timeframe.  The quality of his work is outstanding, his prices are reasonable and his overall understanding of the construction process is of the highest order.


I had a two bathrooms and bedroom renovated for my mother- in- law. Based upon my concept Isaac and his team of sub contractors moved walls on the first floor to facilitate a new stackable washer/dryer, and convert an original 1960’s bath tub set up to a 4 foot wide walk in shower. At the same time we had him install and update the plumbing to the second floor and install a tub shower unit with vent. Custom Concepts had to move bedroom walls on the first and second floors, and cut in new doorways. He also had to update a some of the electrical services and insulate walls and ceilings that were discovered to be without insulation.

I had seen some of Custom Concepts work before, so when my almost “nonagenarian” mother in-law needed to stop going down cellar to do her laundry, and crawl out of her tub/shower unit before she had a fall, I thought of Isaac. Gram, ( “nonagenarian” mother in-law ), is a very sharp lady, but very sensitive to dust and picky about details. In the past other contractors she had hired to do smaller projects had taken advantage of her, and so her trust level was pretty low. So now my creditability and Custom Concepts were both on trial. At the start of the job Isaac had presented a very good proposal with options and how change orders, if needed, would be dealt with. His terms were very reasonable, with a small deposit, and progress payments consistent with the work flow. Per agreement, rooms that were not part of this construction were sealed off to limit dust, and after the extra furniture was moved it was covered and sealed with plastic. Prior to the start of work building permits were pulled and certificate of insurance was provided.

The work went quickly, (this was good as Gram had moved in with us), and the process was about four weeks, which was one week ahead of schedule. Isaac had the demo completed and materials removed from the site right away. He discovered that a couple of walls were not insulated and recommended adding a couple of electrical outlets once things were cleared out. Very reasonable prices were given and approval was granted.

We had four trades on site at different times, (electrical, plumbing, painters, and the carpenters), without problems. Isaac managed the job very well and kept us informed. The team recycled the molding and other materials where it was practical and within code. The building inspections were completed and passed on the first visit for the new work. The town’s electrical inspector required that the outside main feed to the meter be replaced, which was outside of the scope of work, (this added less than $ 500 because the guys were still on site). As the project was almost done, and Gram was very pleased, she wanted to have two of the other rooms painted, with the trim and ceilings because the job was going so well and well within the original cost structure. This task was completed based upon the change order. At last the construction was done, and permits signed off. The house looked very good for a construction site, but the Custom Concepts’ team wasn’t done. They hired a cleaning crew to go through the site to wipe down the walls and cabinets, wash the floors, vacuum the floors with a HEPA vac, and cleaned the windows.

When Gram arrived back home, she was thrilled, and pleased with the clean environment, and the workmanship of the construction. She did discover some dust and debris down cellar that had fallen through the cracks when the plumber was doing his process, and a couple of edges that she wanted smoothed a little more. Isaac himself came right over to inspect and clean up the mess.

Overall we were very pleased with the work that Custom Concepts performed on this job and would highly recommend them. I will also be using Custom Concepts on a couple of projects this winter at my own house.

Isaac Low and his team at Custom Concepts exceeded our expectations! Prior to hiring Custom Concepts, we asked another local contractor to look at our planned 2nd story addition and remodel project. Fortunately, for us, he did not feel comfortable tackling what ended up being a very difficult job. It involved tearing off our roof and living room ceiling, adding a second floor to include a full atrium, master bedroom (with a balcony and walk-in closets), master bathroom, dressing room, laundry room, and office – all this while we still occupied the house. Moving out during construction was not an option and the complex scope of the work did not deter Isaac, who appeared very enthusiastic and up for the challenge when we proposed it to him.

The Custom Concepts team are very reliable, skilled, friendly, professional, and always promptly returned our calls and texts. They are great with children (one of our sons has special needs and just adores Isaac, who kindly helped put him on the school bus several mornings) and pets (making sure the dog doesn’t get out), which was important as my family shared the same space with them every day for many months. Not to mention, the finish carpentry is top notch and whenever we needed guidance and creative input on function or design, Isaac and his team always had a solution.

All in all, we are very pleased with the work Custom Concepts did and it was a pleasure getting to know their personable, hardworking, and talented team. We will definitely be hiring Custom Concepts again for our next home improvement project.

The team was able to complete all the work in one day! They were very professional, covered all our landscaping to protect it from the removal process. They arrived on time and left nothing behind. They even went over our yards several times to make sure they picked up all the roofing nails. We were very impressed.

I would like to take this opportunity to recommend the services of Isaac Low and his company, Custom Concepts, LLC. Isaac and his team constructed an attached two car garage for our home in Hudson, MA. The attachment included a full bath and laundry room. The quality of work and materials combined with a highly professional group of carpenters, plumbers and electricians resulted in an outstanding finished project that my wife and I are extremely pleased with. In spite of the elements, he completed the project on time and within budget.

The sub-contractors Isaac used were all extremely professional and his onsite team, led by Jeff, were excellent. Isaac was always available to answer questions, respond to concerns and changes to our plans. On several occasions while we were on vacation, he sent us photos of the work in progress which was much appreciated.

This was our first project of this magnitude and I can say without any reservations that Isaac and his men performed superbly. I would not hesitate to use Isaac and his company again.
