With a perfect rating of 5 stars from 26 reviews, WesternPool and SPA, LLC is highly praised for its customer service and quality craftsmanship. Clients appreciate the team's professionalism and attention to detail, making it an ideal choice for those looking to build a custom pool. However, the thin review base suggests that while the current feedback is stellar, it may not be fully representative of long-term performance.
Amcon Pool & Spa holds an impressive 4.8-star rating from 19 reviews. Customers commend their competitive pricing and efficient project timelines. This makes them an excellent option for homeowners seeking value without compromising quality. However, some reviews mention minor communication issues during the process, which could be a concern for those who prioritize updates and transparency.
Castle Pools and Spa, LLC enjoys a solid 4.8-star rating from 17 reviews. Clients appreciate their creative designs and reliable service, making them a strong contender for innovative pool projects. Nevertheless, the relatively small number of reviews might leave some potential customers questioning the consistency of quality over time. The review base is still thin, so we read the rating as promising rather than proven and weighted it accordingly. Most of what reviewers hire it for is unique and custom pool designs. It serves Seattle, WA, with $45,000 to $90,000 pricing, and the honest trade-offs are limited review history.
Aqualine Pool & Spa Inc. has a perfect rating of 5 stars based on just 4 reviews. Customers highlight their thorough approach and friendly staff. While this company shows promise, the limited review base makes it hard to gauge long-term performance and reliability. It could be a good option for smaller projects or those willing to take a chance on a newer provider.
Pacific Northwest Pools & Concrete Design, LLC holds a 4.3-star rating from 12 reviews. Customers appreciate their variety of services and solid workmanship. However, some reviews indicate inconsistency in project timelines and communication, which could be a drawback for clients who value reliability. This company may suit those looking for diverse options but with a bit of caution.
