WindowGuru Case Study

WindowGuru is Ottawa’s top-rated window, gutter, and siding cleaning company. They have served residential and commercial clients across the Ottawa region for over a decade, earning more five-star reviews than any competitor in their category.

★★★★★ 335 Google reviews. 5.0 stars. Ottawa’s highest-rated window cleaning company, built on trust, backed by results.

The Challenge

WindowGuru had a working website. It covered the basics: services listed, phone number visible, photos present. But under the hood, it was losing them business every day.

Their performance score sat at 54 out of 100. Pages loaded slowly on mobile. Accessibility errors blocked some users from navigating at all. There was no structured data to help Google understand the business. And the site had accumulated years of media bloat and unused plugins that dragged down every page load.

Most local service searches happen on mobile. A slow site loses those visitors before they ever read a single line of copy.
