Very helpful personal which wasn't too pressing. Massive selection in furniture and accessories. Very broad price range and style range.

I was impressed with the reviews so I sent in the in-line form and also called the company. No response at all. Not good business.

We did a complete rebuild on our home site with a basement and hired Paul and his guys. We now have a beautiful home that is to our specifications. Paul and Rob were great! Patient, knowledgeable, thorough and flexible. We changed our minds about a number of things along the way, Paul and Rob gave valuable insights so we came out with the best solutions. Their attention to detail is evident and their subcontractors are top notch. Paul took care of all the city requirements etc., which made our lives much easier and was available as issues arise, even now after the job is done when we want extra

I needed some siding and wood rot repair on my house. Paul had done an arbor for me over 10 years ago and I liked the workmanship. The repair job was relatively small, so some contractors were not interested. Paul was willing to do the work if I was flexible with timing, which was fine with me. I don't mind waiting to get a job done right. His crew arrived on time (rare among contractors) and finished as estimated. They were efficient and thorough. At some point I might redo all the siding and would not hesitate to call Paul.

Paul is an excellent professional. We recently completed a remodel of our house and the attention to detail is great. All his subs did a nice job too and we had very little to worry about! Highly recommend for any construction work - big or small!

We used Vandonzel Construction to remodel our house in San Carlos at the beginning of 2010. They did an exceptional job all around - they moved quickly, had great subcontractors, were flexible with changing design plans, made great suggestions along the way, and were very competitive in price. If we ever remodel / build again, we would absolutely use Paul...

We absolutely love Paul! Not only is he an excellent contractor. . . he is also a really nice guy and so easy to work with. He has done a couple of additions for us and most recently he installed all new windows and french doors in half of our home. He makes what seems like the impossible possible and has never let us down. He is an excellent carpenter and has a great sense of design. We highly recommend him. We wouldn't think of using anyone else.
