Our Philosophy

Back when our founder Alex Traube was still an independent electrical contractor and sub-contractor, he saw the need for home renovation contractors in the Cleveland area who were not only hands-on, efficient and accountable but who actually listened to their customers’ needs, thoughts and concerns.

That’s what inspired Alex to start SEMA Builders. Founded on the following guiding core principles:

The customers need to be heard

Our motto “we listen to your needs” is much more than a catchphrase. It is our core belief that you as the homeowner need to be informed and involved in all the decisions that guide your home renovation project. After all, it is you who will be living in the home long after the project is complete. This is why we listen to you and understand what it is you are trying to accomplish. It is only after we’ve come to a complete understanding do we offer our expert professional opinions on the best and most cost effective way to accomplish these tasks.
Your needs, concerns and ideas, along with our professional guidance, are what help our team to help you realize your home improvement dreams

Trust & Transparency

As professional home renovation contractors, there is nothing more frustrating to us than hearing the horror stories of unscrupulous general contractors who give our industry a bad name. Hidden costs, incomplete projects, messy job sites and general unaccountability. The list goes on and on.

That is why we at Sema Builders are committed to debunking those negative stereotypes with every assignment we undertake.
First and foremost we do this by building trust and transparency.
We take pride in the fact that honesty and integrity are the hallmarks of Sema Builders’ reputation. When we say or pledge to do something, we mean it and stick to our word.

Your free estimate quote will be the price you pay. No hidden fees, extra charges or surprises.

We stick to the pre-established schedule and overall project timelines.

Alex, our founder, doesn’t just coordinate projects with his team and other subcontractors. He personally gets hands-on and involved in your home renovation tasks making him very accessible and readily available to you at any time.

Accountability & Communication

Clear communication between us and our clients is vital. This is why our founder Alex avails himself to you anytime you need. Be it on the jobsite, by phone, email or text, we are committed to responding in a timely fashion so that your needs and concerns are addressed as soon as possible.

Furthermore, we always keep you in the loop of our progress so that there are no surprises should anything happen.

We are fully accountable and responsible for our work. No excuses. If the work is not to your satisfaction, let us know immediately so that we can rectify it immediately and exceed your expectations.


We respect your time, money and property. To that end, we do everything we can to minimize disruption.

Our crews are always polite and are trained to remember that a job site is first and foremost your home.

We will never leave the job site messy or dirty. As much as possible, our tools and materials will be put away at the end of each day so that you can continue enjoying the rest of your home without concern for your family’s safety.

Attention to Details

Our strength lies in our ability to bring our projects in on time and on budget, while paying attention to every detail along the way. This extra attention to detail can take a good remodeling project and make it spectacular. We are committed to working diligently to meet and even exceed the expectations of our clients.
