Construction Company reviews in Falls Church, Virginia

I really liked how they worked at my house. They left a clean and well-done job.

I really like Demarr and its employees, you are the best of all I have seen,very professional, take ownership and always on top of things.
We are very satisfied with the work they perform. Very upfront on the pricing and no hidden costs or surprises. I would highly recommend to anybody.

We made a good decision by taking DeMaar services for our site work. They were totally professional and very helpful through out the construction process. We are very much satisfied with their pricing and quality of work. No hidden costs everything is very clear. Highly recommend to use them for your site work. Ask for Brendan. Very professional and helpful guy. On the whole, a very reliable company.

DeMarr has been wonderful to work with. The company knows the process, sticks to the timeline, and is very responsive to questions and concerns. We have been very satisfied with their work throughout our home rebuild and would highly recommend them.

We are very pleased with the expertise and hard work of DeMarr Construction to install and connect our exterior water line from a private well to the Fairfax Water main. Brendan explained the process and provided a detailed drawing of the impacted area and tasks to complete the work. He coordinated with our community association and Fairfax county permitting. The installation crew completed the job on time, filled the trench, and covered the area with grass seed and hay. We especially appreciate the clear communications throughout the process and highly recommend DeMarr plumbing.

DeMarr Construction fabricated and installed a 16' x 10' x 4.33' lined concrete planter box and associated drain field for house gutter downspouts that was required by Fairfax County for permit approval of the pool & spa we recently had built.

DeMarr did an incredibly fantastic job and completed the project on time and below estimate! Professional and responsive every step of the way. Great communication and project coordination.

They turned this county requirement from an expected eyesore in our backyard to an attractive complement that blends in with our existing lawn.

I couldn't recommend them more highly to complete a complex project that requires site development, land clearing, excavation and fabrication of concrete forms, etc. requiring close coordination with subcontractors and county inspectors.

Excellent service and craftsmanship. I turned my existing porch into a mud room and it turned out even better than expected! Thank you Rob and Tim for running the project and HUGE shoutout to David and Jose who are master craftsmen!

My Builder provided a reasonable estimate for our renovation, delivered great workmanship, and always treated us with respect. We can't wait to show our family how things turned out!

Would not recommend

I hired MyBuilder (Tim Cebulski) based on a quote that was over $10,000, given solely from my engineering drawings—no site visit. Tim promised a start, but the crew arrived late and unprepared, then couldn’t begin. The next day a different crew showed up late again and said Tim told them this was a “1–2 hour job,” which was alarming given the original ~$10k quote.

They then claimed there was additional work “not in scope” (including masonry) even though it was clearly shown in the drawings I provided. After two days of delays, Tim emailed on saying they couldn’t itemize a quote yet but the “lowest possible” cost had jumped to $19,000–$22,000. When I pushed back about the escalation and lack of prep, he canceled the scheduled framer and engineer instead of standing behind the original plan.

This was poor communication, missed commitments, and a major last-minute price increase. I’ve paused the project and will be seeking contractors who actually inspect the job up front and stand by a realistic quote. I do not recommend MyBuilder or Tim based on this experience.

I have worked with Rob on 3 major projects; 2 renovations and a significate addition to my home. He is knowledgeable about all aspects of building, and did an amazing job incorporating a new roof with my 100 year old house tresses. Rob works with you from start to finish. He is great!

Great service from this general contractor! They handled my project with professionalism and strong attention to detail. The team was reliable, communicated clearly, and ensured everything was completed on time. The quality of work was excellent, and the entire process was smooth and stress-free.

Excellent service’

Good Professional Team Highly Recommended

Very knowledgeable staff. My experience with these folks has been amazing. Highly recommend then for your house uplifting needs be it remodeling, appliances, vent Cleaning, AC or heating related work etc.

This company is fantastic. Same day repair to my furnace. I am so pleased and I am a repeat customer. I highly recommend!

Very good service. Mr. Abrar is the best.

AZA makes the process as easy as possible from start to finish. Their customer service is excellent. They have routinely worked around my schedule well. Originally having multiple old HVAC units meant over the last couple of years, I needed to find trustworthy HVAC techs. AZA is that. They guided me along the process to know when it wasn't worth fixing one of my old units and when it was finally the right time to do a full replacement. Don’t waste time searching—call AZA when you need service, maintenance, or even a full replacement.
