Geat planning, timing, framing, finishing with integrity and high ethics !!

We purchased a home needing refinishing of the lower floor – the timing, the cost, the satisfaction and the wearability of buildout was far above expectations –
It was a delight to watch the progress in a time-frame that was amazingly well thought out and delivered –

Amazing !!!!!!

A First Class GC

As an engineer, I’ve worked with Ken for over 15 years on many different types of projects. He is and always has been a great person to work with. He is very open and communicative about the needs and goals of the project. Ken always wants to get it done the right way without cutting corners. We might discuss different ways to cut cost, but never with a sacrifice to quality. I have always enjoyed working with Ken and hope to continue to do so. I highly recommend Ken and Grein Custom Homes.

Master Bathroom Remodel

It was a great experience working with Ken to completely remodel our master bathroom. We went from a traditional five piece master bathroom (with separate shower and tub), to a contemporary design that got rid of the bathtub to make room for a larger walk-in shower concept. To start, the ending quality was fantastic. The craftsmanship and attention to detail was top notch, especially the tiling work. Furthermore, it was a very smooth process. It’s important to find someone you can easily work with for a project like this, as there are many moving pieces. Ken was fantastic at communicating and setting expectations throughout the project. He was also great at sticking to a well-coordinated timeline. In fact, the project finished ahead of schedule, which was very much appreciated. I would definitely work with Ken on future projects, as I appreciated his effort in building a working relationship while also getting the project done timely and with great quality.

Loyal Customer

We have been Grein’s customer since 1988.
He built a beautiful custom home for us that we moved into in 1989. We loved the beautiful work that was done on-time and on-budget.
By 2016, we now lived in a 1910 farm house and had been wanting to add onto for some time, but, had heard too many horror stories about other’s projects coming in late, over budget or abandoned.
We managed to reconnect with Ken. He provides realistic pricing that will not have anticipated surprises. With an old house there are bound to be unanticipated surprises, but, Ken is very honest and explains the process. We actually had some of the same subcontractors who worked on our original home in the 80s! That speaks volumes!
We are finished with our new addition and enjoying the beautiful work and the lasting relationship.
Other contractors may come in with lower initial numbers, but, when it is all said and done, Ken gives you the realistic price at the beginning and we were able to enjoy peace of mind that we would be within budget (unless we chose to change something from the original).
Ken was on-sight overseeing the project almost every day and even running for materials when needed to keep things rolling smoothly.
We appreciate the long relationship and can rest assured that he will be here in the future if any new needs arise.

Remodel our new house

Our new house came incomplete for us. We had no choice in the features as the home was already specified. We had some ideas and we made the easy decision to hire Ken Grein for our projects. Ken was always on time and had clear communication with the process. We just smiled as his approach had not changed since the 1st project we used him on at our other house years ago. Even with a new house there are some issues that arise. We all worked thru them with ideas and workmanship for a wonderful outcome. Now when you enter our new home the craftsmanship just pops. We are thankful everyday and blessed to know Ken Grein


We have wanted for years to create spaces for our family band to rehearse, and for our boys to have their wood shop. The Grein family has built our home (2002), and finished our basement (2012), and have now completed our third addition to the property. We did check out other builders for this particular project, and ended up choosing Ken again for the job – being reminded once again why other options really aren’t an option for us. Having finished the job on budget and on time, we are again reminded why we chose him. His integrity and character are of the highest degree, and clearly distinguish him from others. He also sets himself apart in communicating regularly, providing regular updates, presenting any issues that arise, or presenting questions that need to be addressed. Once again, we were very happy with Ken Grein’s leadership on our project, and with the end results. No regrets! We are truly blessed by His work and leadership.

Perfect and did what he said he would do

Ken was awesome to work with. Walked me through the process of remodeling my home and together we discussed what we thought would be best. I appreciate that I felt I was part of the team and was always updated on the process. I am very grateful and happy with the whole experience and the results of the work was amazing.

Bedroombathroom remodel

My wife and I decided to remodel our master bedroom and bathroom. We wanted a trust worthy contractor that has a history of quality work and the highest regard to their customers needs and wants. We had a few companies give us quotes on our project. After talking to each contractor and comparing the quotes we decided to use Ken and his team. We felt more comfortable with Ken’s team. Everybody from the drywaller, plumber, electrician, tiler and the finish worker were all respectful of our house and completed amazing work. We will always use Grein Custom Homes and will refer them to anybody that needs a great contractor.


This is the second time I have worked with Ken and his team, and I wouldn’t hesitate to work with them again. They did a fabulous job on my master bath in a previous job, and once again did a fantastic job on a smaller bathroom. We really love the way they both look and function now. Ken is always available when you need him and will accommodate a small change when you want it. He is incredibly easy to work with, and just a wonderful all-around person. His team is efficient, skilled, knowledgeable and courteous. You simply can’t go wrong!

Would work with Ken again in a heartbeat!

We really enjoyed working with Ken and his team on our remodel. We knew we wanted to make some improvements to our home but were not sure exactly how we should do it. From the very beginning, Ken brought his experience and knowledge into our planning process. He let us know what our options were and the cost considerations for everything. Once we figured out the specifics of what we wanted to do, Ken and his team executed brilliantly. We had a lot going on in our remodel: replacing windows, new wood floors, moving walls, new kitchen, new bathroom, painting, etc.. Ken is an excellent planner and had every detail and timeline covered. The subcontractors showed up when expected and performed their work quickly and with high quality. It was clear to us that everyone had great experience. They figured out most details on their own and worked with us when there were important decisions to be made. We lived in the house throughout the remodel and everybody was sensitive to that. The crews cleaned up after themselves and worked within our timeframe to make it as livable as a remodel of our size could possibly be. We are blessed to have found Ken to do our remodel and would work with him again in a heartbeat!


I am a retired teacher, now a budding artist. I needed someone to finish my basement into an artist studio, plus have a room for general storage. Ken and his team delivered what I imagined in every aspect. The work was done quickly, professionally and efficiently in 6 weeks. Every person that worked in my home was professional, polite, friendly and produced quality work. I am very happy with my experience with Ken and his team.

Wonderful Experience!

We were honored to have Ken Grein and his team work on our home. From start to finish Ken was honest and timely. He was the only contractor we consulted who was willing to complete our project to our specifications without overselling or overcharging us. He willingly worked with us to find the perfect arrangement for our kitchen remodel. The work was completed in a timely manner while we were on vacation and Ken kept us up to date with pictures and phone calls as needed. We highly recommend Ken Grein.


Grein Custom Homes is a builder who will make sure his clients are informed and satisfied with their end product of a beautiful home. We have supplied Cabinetry and work with Ken’s clients and help create a beautiful functional Kitchen, Bathroom cabinetry , etc. He works with budgets and has knowledge and experience with a friendly attitude. This makes all the difference with working through the home building process.


Ken Grein and his people did a complete redo of our house. Every surface in the house was redone, with many upgrades, including countertops, carpeting, tile work, cabinets, flooring, and crown molding, to say nothing of repainting the entire house and replacing some doors, as well as all door hardware. We had a number of contractors in the house daily during the project, which took about six weeks. Without any exception every subcontractor was a pleasure to work with. They were all punctual, they all worked hard and did not waste time, and the quality of their work was top notch, in several cases, they even suggested ways to save money without losing quality. If you have any work to be done along Mr. Grein’s line, I strongly recommend that you consult him. I know you will not be disappointed.


Having used contractors before, my wife and I were surprised at how different Grein Custom Homes was from the others. In the massive remodel and upgrade of our kitchen we found Ken to be friendly, knowledgeable, timely but more important clear in what needed to be done and how best to accomplish our objective, a gourmet professional kitchen. We were worked with rather than against in picking details, expression of our views and desires, the levels of quality and layout to be achieved. Ken helped resolve the problem encountered by surprises in the walls.


We have used their service for Bathroom remodeling and were very satisfied. Anytime if I have any problem with my house, we call them first to get their opinion and quotes. Really great customer service and awesome workmanship.


Ken Grein is a thorough and professional general contractor with the skills and attention to deliver an exquisite final product. He has built a lasting relationship with high quality and extremely skillful sub-contractors and, as a team, delivers on their estimates to the dime. My wife and I would not even think about contacting another contractor no matter the size or significance of the project – Grein Custom Homes is simply the best!!!!


We recently had new windows installed throughout our home. Ken Grein was the general contractor and did a superb job on every aspect of the project. He was available by phone for all necessary communication almost immediately. He met with us at the beginning of the project, stopped by several times to inspect the progress, and met with us at completion to make sure we were satisfied.Ken is a a true professional in that he has a high standard of work quality in his personal construction and communication skills and in choosing his sub contractors. He responded quickly to all questions and concerns we had from start to finish. We would highly recommend Grein Construction to others.


Ken Grein and his team built our home and helped make our dreams become reality. Ken was great to work with throughout the process. From the time we discussed our plans, received bids, started the build to completion, the entire process was perfect. Ken is great with his communication, project management skills and there were no surprises along the way. If you need a great builder, one that you can trust, rely on to do what is right and ensure timelines are met to stay on track, Grein Custom Homes is the right choice. I would highly recommend Ken and if we ever build again, I would not use anyone else but Ken and his team!


Excellent customer service – great contractor! We have used Grein Custom Homes on two remodel jobs and were very satisfied.


I contracted with Ken Grein to build a custom home for me in Thornton. At the time I was still living in CA during the build. Being over 1,000 miles away many thing were handled via phone calls and emails with pictures. I met with him just once or twice during the build to finalize some details and have input6. Even though i was far away, I trusted him completely. I received invoices as they came up for payment and copies of all payments and monies spent. Everything was detailed down to the penny. I couldn’t have picked a more trustworthy, honest person to deal with. I felt totally comfortable with him in charge and was extremely pleased with the outcome and the build of my home. If any issues arose, he handled them quickly and he stood behind his work. He made repairs and touch ups as I requested and never complained about anything. I don’t think you could find a more honest, trustworthy person as a builder. I highly recommend him to anyone thinking of doing any construction or remodeling work. You won’t regret it.
