"Installation was solid. The labor price was a bit high. The main concern was the materials markup. The picked up a shower stem from Lowes. Those are normally about $50. The tech said that the stem wasn't $120 but they charge them extra when they use their contractor code. That seemed weird since normally get discounts since they purchase a lot. I should have questioned it but it didn't register to me until after he had left."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

Caffi Services has served the DC Metropolitan area since 1967, and has earned the reputation for top-quality products and services at a fair price.

"My partner and I recently moved into a new house in North Arlington and developed kitchen area plumbing problems. Caffi Service Representative Patrick Bache arrived in short order to make all necessary repairs. Patrick worked quickly and efficiently and thoroughly cleaned up when repairs were finished. He answered all our questions and made very helpful followup suggestions. We've been satisfied Caffi customers in Northern Virginia for over 20 years and knew that we would get the same A-1 quality service from Caffi at our new house that we had received over the years at our former address. Believe me when I say that -- in our experience -- when you go with Caffi you get the best."
