We've helped so many others build their dream homes, let us build yours too!

Howie (owner) and the team at Great Additions were amazing! Punctual, truthful, honest, answered everyone of my questions and phone calls during the entire process! My dormer and entire house remodel went as planned and also every one of my concerns were addressed and in a punctual manner. All the workers were extremely professional as were Mr. and Mrs. Gumpel (owner). Howie was at the job site everyday which gave me such a sense of security when I couldn't be there. I would highly recommend Great Additions to anybody. I have had nothing but a great experience with Great Additions and have not one bad thing to say.

I have worked for a lot of General Contractors over the years, and I can confidently say that I think that you're one of the best. Your staff makes it easy to work for you, by letting me do my job and by giving me all the information I need for that job. You have a great clean-up crew which I also find helpful. You also pay right away for my services. Most companies have no idea what they are doing, but you guys do it right and should get all the work!

Great Additions did a fantastic job! The quality of the work completely exceeded our expectations. Howie and Greg are the consummate professionals. They were able to build everything we asked for. The work proceeded quickly to very high standards with tremendous attention to detail. My wife and I are absolutely thrilled with the way the job turned out. I can wholeheartedly recommend Great Additions to everyone.

Great Additions added on a full dormer, and completed siding and structural work. They were responsive, mindful of our budget, efficient, and friendly. We highly recommend them to others.
