This company did a demo/buildout for me and my ex wife. A new master bedroom with all the extras, walk in shower with seating for 3, toilet, a bidet, double sinks, mirrors everywhere, and even a urinal. The room turned out awesome! Unfortunately the marriage went to shit. Now I enjoy the room with whoever I please, whenever I please. Thanks for the great room, it's pretty much all I have left. I love women and they seem to love me and my master bedroom!

I used Brian Allendorfer Company to replace two HVAC units in my business. I went with them after receiving quotes from two other companies. Brian Allendorfer Company's quote was the most reasonable and the staff, in my experience was the most professional. My contact was Scott who was knowledgeable, polite, and always available to answer questions and concerns. He made the experience comfortable from start to finish. I am very happy with the work that Brian Allendorfer Company provided and plan to use them again for future needs.

As a Landscape Architect, I have been working with Brian Allendorfer Company, Inc. for over 5 years on a variety of high-end custom projects including roof decks, pergolas, decks, privacy screens and more. Not only do I recommend them to my clients, I have also hired them for my own home. Brian's extensive expertise in everything roofing blended with Scott's highly skilled craftsmanship in construction makes for a perfect combination.

We were very pleased with all the outdoor construction work that was done by the team at Brian Allendorfer Company! Everyone was very professional and the attention to detail was especially wonderful! We had a back cedar deck built along with a pergola and it looks great! We receive so may compliments! They also installed our new windows and siding! All looks great! We would absolutely recommend!
