YalekLocal Guide · 30 reviewsTotal number of Google reviews this person has written across all businesses on Google Maps (not just this one). More reviews usually means a more experienced, trustworthy reviewer. · 3 years ago★★★★★Shimmer is our 5th pool service company. Shimmer scrubs the sides, vacuum the pool and check the chemical balance of the water in every single visit. No other pool company had done that before. Our pool now is crystal clear and shimmer. Shimmer team did an excellent job to take care of our pool.
