Rancho Cucamonga, CA - (12-2) COD. Spoke with Randy, he is the homeowner. He has a backflow valve attached to his backyard hose bib that helps fill his pool. It is currently failing and he had to turn the water off to his property to stop the pool from over-filling. He would like to get an estimate to get this repaired and get the water up and running to his property ASAP (he is having surgery tomorrow and wants to make sure his family has water BEFORE then)! Please get approval on any pricing BEFORE performing any work! He is hoping we're not as "money hungry" as All Pro. He had called them for services first and he felt like they were just trying to take advantage of him!

Thank you so much for taking the time to leave us this amazing review!

Review
We are extremely happy with Klaus & Sons. Their workers were on time, did what they were hired to do and cleaned up after themselves. That said, the men were friendly and attentive to any questions or suggestions we had. They laid protective padding over the entire work area, and after each days work (2 in our case), they put everything back in place, removed the coverings and vacuumed any materials left. They placed the things they removed in their truck (not in our bins like some workmen we have had)and took it away at the end of each day. We couldn't have been more pleased! Just noticed the question on rating the cost/pricing of their service. They were not the least expensive nor the most expensive, but they were well worth the price!
