Customer Reviews

Kathleen H. Kent, WA
I had Allied 1 replace a 42-year old driveway. The job was a bit tricky but, everything came out great! Hughbert and his crew did such a good job, I'm having them replace my old rod iron railing on my concrete front porch! Kathy H.
Laural T. Covington, WA
After a driveway project left the sides of the driveway messy, Hughbert and his team returned to help me prepare the area for reseeding. He graciously brought extra topsoil in to finish the project. He is considerate and detail oriented.
Chris P. Seattle, WA
Allied 1 did a phenomenal job pouring us a driveway and helping us with our drainage issues. They proactively communicated, kept me in the loop, made thoughtful suggestions, and executed perfectly. They definitely know what they are doing and that shows in their laid back demeanor. They make me want to make my whole yard concrete just so I can hire them again.
Michael R. Renton, WA
I had them pour 2 different areas, They are good and fast. The owner is very nice guy and explains things to you. Would hire them again and give my recommendation.
Rick P. Redmond, WA
Hughbert and his crew did a very good job on my project. Their pricing is competitive with others. We had our driveway, walkways and porch redone in brushed concrete. The removal of the old concrete, framing, pouring, finishing and cleanup went as scheduled and the finished work was to my satisfaction.
David B. Seattle, WA
Hughbert is very professional in his trade experience and customer service. My project with him went well, so well I added on to the scope mid-way through and he accommodated the additional work with a fair change order and performed the work in a timely manner. The finish work on the concrete is a work of art. Appreciate Hughbert and his team!
