Client Testimonials:

  • “We worked with Heltzelhaus and its affiliated architectural firm from Spring 2014 to Spring 2015, planning, designing, and constructing a significant renovation to our home; and the result–we could not be more pleased. Heltzelhaus employed top notch personnel every step of the way and insisted on the best materials–and it shows in every detail. Excellent design and construction, however, is what one anticipates when he or she enlists a top-notch firm and with Heltzelhaus one gets that and something just as important–outstanding customer service. The responsiveness, friendliness, and professionalism of the Heltzelhaus team stood out. Heltzelhaus delivered a gorgeous renovation at the highest quality of craftsmanship and not a week goes by that we do not comment about how happy we are with the result. ” – Christine H., Great Falls, VA, March 2015
  • “We worked with Heltzelhaus, architect John Heltzel and contractor Curt Zeise on a master bedroom/bath remodel 12 years ago and now moving to a new home we have returned to this wonderful duo. They are very creative, efficient, excellent craftsmanship, work with you to address concern/changes, clean up the job site and are pleasant company to have around. We love our master bedroom/bath and will post pics of the new one when it’s completed. We plan to use the team to remodel our kitchen next year. ” – Joy E., Reston, VA, May 2014
  • “John and his team are top-notch. They finished a complete remodel of my 1st floor three weeks ahead of schedule and on budget. The job entailed moving a powder room, expanding and updating the kitchen, sanding smooth a textured ceiling, replacing hardwood floors, eliminating a side entry door and replacing it with a window, and moving a garage entry door. The end result was fantastic. I highly recommend HeltzelHaus. ” – John & Jehanne S., Fiarfax Station, VA, July 2013
  • “Thank you to the Heltzelhaus team for your hard work on our kitchen project. John provided thoughtful insight and guidance throughout the design and construction phases. Curt made sure that the project progressed smoothly and was completed on time and within budget. Mandy’s organization ensured open and reliable communication. And Mike provided dependable daily guidance and excellent workmanship on-site. It was a pleasure working with your team, and we truly could not be happier with the result.” – Maureen C., Arlington, VA, November 2012
  • “…We wanted to pass on many compliments from neighbors on the color of the brick and the construction in general. While we were there this weekend, many neighbors stopped by to comment on, in their words: ‘Our very good looking house and excellent progress’.” – Attila & Anna F., Great Falls, VA, May 2012
  • “Thank you. We are very pleased with everything. The entire neighborhood has given rave reviews on your workmanship… You have done a great job and everyone loves all your work – the portico has really been a hit!” – Sharon G. and Terry W., Alexandria, VA, March 2011
  • “You and your firm are the most congenial and dependable firm I have ever had the pleasure to work with. “ – Patt G., Fairfax Station, VA, August 2010 (Repeat client)
  • “Thanks so very much for the patient assistance you have provided over the past year. Actually, two years! Your entire firm is full of wonderful and thoughtful people.

  • “We continue to love Smithfield and everything about it – especially our nice home – thanks to you.” – Jim & Bobbie B., Smithfield, VA, January 2006
  • “This renovation would have been unbearable were it not for our wonderful architect, project manager, and carpenters… The entire project was completed with all the finishing touches in September and we are thrilled with the results! …It has been an incredible blessing for our family.” – Tim and Andrea M., Clifton, VA, December 2003

  • “Thank you so much for a job well done that will lead to years of enjoyment for us. Working with you was great, too.” – Rachel W., Manassas, VA, November 2003
  • “Our project has come to end and I must say we are delighted. You would not believe how many people have stopped to look at the house. Some of the design work, such as the porch, the second floor deck and the skylight from the top floor to the bottom floor, really set the house off, just to mention a few. The quality of work was excellent and I am certainly glad that you did the work as well as the design. Curt Ziese, your foreman’s presence each day on the job was the key to a smooth operation with the number of different contractor personnel showing up on different days. His skills in general carpentry, and other requested work… should not go unmentioned.” – Joan & Chuck E., Springfield, VA, June 1995
