HSL Building Company, LLC

We basically rebuild our house from top to bottom and HSL was very professional and very responsive throughout the project under difficult circumstances given Covid-19. Would highly recommend Erno and his team for your next project

As a provider of quality building products, it has been my pleasure to work with HSL Bldg. Co. for more many years now. They are a professional, quality oriented company with an eye for details. A courteous and considerate group to work with, and I look forward to working with them in the future. Pete Randall Woodbury Supply Co. Inc.

Erno and the HSL team are outstanding! We were presented with a detailed estimate and timeline for the project. The craftsmanship was the highest quality and the work was completed on time and on budget, all the while keeping the work site clean, safe and livable. Erno is friendly, energetic and knowledgeable, but best of all - his communication skills are outstanding. I would not hesitate to use Erno and the HSL team for any project, big or small.

We highly recommend the HSL team. We first met Erno Bacso about 6 months before demolishing our existing home and starting over. Since then we’ve been impressed with the level of attention to detail and craftsmanship they have brought to building our home. The HSL team is professional, kind, responsive, conscientious, trustworthy and knowledgeable. Weekly meetings helped us to communicate about big decisions and work through smaller details. From start to finish their attentiveness and focus on quality has been unwavering. The HSL team is a pleasure to work with and built a home that has exceeded our expectations.

HSL is simply the best building company you could ask for! Working with Erno Basco and the entire HSL team was an absolute dream! HSL was there every step of the way to make sure that our renovation ran smoothly and was completed on time and within budget. The team at HSL could not have been more accommodating before, during and after our project, making sure that every detail was completed to our utmost satisfaction. Erno Basco is a true professional and did a fantastic job coordinating with every trade, especially the design and architect firms, who were both also amazing. We highly recommend Erno and the entire HSL team!

Excellent job. They finished the job on time and within budget. They have painted the interior of my home and they just finished power washing my roof and treating it for the winter. I will use them again and I highly recommend them.

Erno is detail oriented, talented and an expert in the field. Trustworthy and energetic, always exceeded my expectations. He is on the job overseeing the smallest detail of the project making sure that everything is exactly how the owner dreamed about.

We have collaborated on several occasions. Always professional, creative and pleasure to work with. Can't wait to see what projects are yet to come!

We were fortunate to work with Erno Bacso and his company, HSL, on a major renovation of our home including expanding the kitchen into adjacent rooms & installing a second floor deck. We are pleased with his work and with the results. Erno and his subcontractors do high quality work and care very much about satisfying their client while staying on budget. His subcontractors (such as carpenters, cabinetmakers, and painters) are friendly, decent people who were serious about the work and were a pleasure to have at our house. Now that the job is done, we miss them! Some of our work was quite challenging as we created a modern space in an 1867 farmhouse, and Erno and his team were creative and resourceful in giving us the sort of space, finishes, and feel we wanted. One night during the project a large and complicated mirror began to separate from the wall in our daughter’s bedroom. We feared we would have a shattered mirror and 7 years of bad luck. We called Erno for advice. Even though this was not related to his project, it was our good luck that Erno drove over immediately with his toolkit. He propped up the mirror and then had his carpenters visit the next day to secure it permanently and properly. Erno was not on the clock when he did this: it was just part of his high work ethic and commitment to serving his clients. An engineer by training, Erno strikes us as being on the forefront of using technology to track his projects and billings. His bills are clear and he is able to give clear answers about production schedules, past payments, change orders and future costs. We recommend Erno and his company HSL highly for their work, their conscientiousness and their integrity.

HSL was hired as the general contractor on a major renovation for a project where I was the Owners Rep in Greenwich CT. Erno was consistently diligent, fair and responsive throughout the entire process and coordinated effectively with the entire Team that was assembled to manage a comlpex series of phases to renovate a 1890s victorian. His crew was professional and considerate and they did an excellent job facilitating a complex series of tasks.

Excellent work at a fair price. Erno started the job when he promised and completed the job expeditiously. Erno did everything that he promised.

We worked with HSL Building on a major renovation of our Westport home and are thrilled with the end-result. During the renovation, we found both Erno (the owner) and Jay (our project manager) to be professional, responsive, organized, engaged, and very committed to delivering quality work. They also had a great collaborative relationship with our architect. We have continued to work with Erno on some small projects and he is always polite, kind and just an all-around nice person who seems genuinely excited about what he does. I am sure we will continue to work with HSL Building for years to come.
