Reviews
What customers say
Customers praise Westlake’s transparent, dependable communication and careful craftsmanship; some also say the team’s design ideas improved their plans. One customer who sold a Westlake home nearly 15 years after it was built said it still looked almost brand new. An earlier client says the project finished on time and the team quickly resolved unforeseen issues, but also reports that it went over budget without visibility until construction was well underway.
