Good Company

Original installation had a problem with thermostat and we had to try a couple times, but Raoul took over and he was great. Found the problem and fixed it. He was very knowledgeable, patient and explained everything. We are now very happy.

Overall Outstanding!

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!

Per Courtney "12-2 (TIME REQ). NET30. Spoke to Daniel (community manager). Main gate code: #3303. Please call Daniel when you get there! - 626-710-3763. Him or one of the board members will let you in to the pool area. The water heater in pool area vent detached so had to turn it off. Also, in the women's restroom there, the little flush thing might need to be replaced, not working. Get approval from Daniel before performing any work." Daniel also wants to have 8 pressure regulators checked and marked if they are not working right so they can try and get them fixed.
