Muhler holds a rating of 4.3 stars from 79 reviews, with customers noting good craftsmanship and competitive pricing. They are a solid option for homeowners looking for affordable window installation services. However, some reviews mention inconsistent communication, which can lead to misunderstandings. That is a substantial body of feedback for a local operator, enough to trust the rating rather than credit a lucky streak. Most of what reviewers hire it for is budget-conscious homeowners seeking decent quality. It serves North Charleston and surrounding areas, with $250 to $600 per window pricing, and the honest trade-offs are inconsistent communication and mixed customer experiences.
