“Our project was a 14 x 22 foot addition to our living room. We received proposals from two other home remodelers. Heltzelhaus’ knowledge of construction, their notable reputation, and 27 years of experience are the qualities that swayed our decision to choose their company to build our home addition. With all that said, they also came closest to our budget allowance. They worked to keep the project within budget and meet deadlines. Curt Ziese, Heltzelhaus Project Manager, was onsite most days of construction. He told us who would be showing up at our home for each phase of the job, and we always felt comfortable with and confident about the individuals working on our property. Curt was unwilling to walk away from any part of the project until it was absolutely perfect, whether it was the quality of labor or materials. We will definitely hire Heltzelhaus to do our next home improvement project!” —Carol S., January 2022
“I am so glad we chose to go with Heltzelhaus Inc for our renovation! Everything about this job was handled beautifully. John did a great job designing our project and helping us to keep it in line with our budget. The construction manager, Curt Ziese, was fabulous to work with. His coordination of the job was superb. It was no easy task to coordinate the different tradespeople coming into the house to work in the middle of a pandemic. He made sure that everyone had a safe environment to work in and that no detail was missed. As a result, we have a beautifully renovated home that we absolutely love! A big thank you to everyone at Heltzelhaus Inc. You are just the best!” — Michelle S., August 2020
“From the beginning to the end of our bathroom remodel project, we were very pleased with Heltzelhaus. The entire team was a pleasure to work with and very good in their roles. Their ideas for designing our bathroom were excellent and the execution of the work was high quality. Project management was superb with honest advice, timely and frequent communication, and no hassle follow up when needed to address an issue. Without question, we will use them again for any other major home renovations.” — Kate C., June 2020
“Curt, Mike, and Tyler did a fantastic job on my kitchen remodel. It looks beautiful and Mike’s carpentry skills on reusing my existing crown moulding to maintain the original look of the house was great. The project went smoothly and they are just all-around nice people to deal with.” — Debbie D., November 2019
“Our project included a semi-attached addition with a pool/guest house, a new patio with covered pavilion, and an additional garage. John was able to make this work within our constraints (easements, etc.) and tied it in well with the style of our house – a stucco Spanish colonial. We hired Heltzelhaus in the Spring of 2016 for the construction project. John and his team worked with us to keep within our budget while achieving our design goals. Curt, the Heltzelhaus construction manager, stayed on top of everything. He was at our house first thing in the morning to make sure any subcontractors showed up on time and had the direction they needed. Where decisions were needed, he made sure to provide us advance notice so we could be thoughtful and not rushed. Considering all of the stories we’ve heard from friends about difficulties they encountered with addition and remodel projects, we feel lucky to have had the opposite experience. Based on our experience, we wouldn’t hesitate to recommend Heltzelhaus.” — Chad S., March 2018
“Working with Heltzelhaus was nothing short of exceptional. Every stage of the project, from design to execution, to even small follow up requests I made almost a year later, were handled with timeliness, professionalism, honesty and integrity. My addition and renovation was started in November of 2015 and finished on time and on budget in the Spring of 2016. John worked closely and patiently with me on my design, meeting all my expectations, plus some wonderful additional ideas. Curt ensured that the every detail of the execution of the project progressed smoothly and with excruciating attention to detail. Frequently, you hear horror stories of projects gone wrong, or poor communications and delivery by contractors. There is not one thing I was displeased with or unhappy about with this project and working with Heltzelhaus. In addition to their outstanding work, John and Curt were a pleasure to work with. I have since recommended them to other friends, who have completed projects with the same level of sanctification. ” — Jill J., June 2017
“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
“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., Fairfax Station, VA, July 2013
“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
“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)
“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
“The job was done with quality and integrity and we never hesitate to tell anyone who asks that you did an excellent job.” — Jonathan W., Manassas, VA, November 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
