We are a San Francisco contractor specializing in waterproofing and the masonry restoration of landmark and historically significant buildings.

We are an approved restoration contractor by city, state, and federal landmark agencies. In addition to restoration services, we also provide historical studies, specifications writing, and project supervision and management.

We work closely with landmark architects in testing, providing samples, and establishing procedures, as well as documenting the projects. Every phase of restoration is done in strict accordance with landmark agency requirements.

We perform restorations of concrete, plaster, brick, stucco, granite, sandstone, limestone, marble and terra cotta. As an approved applicator for many manufacturers, we can provide a wide range of restoration and waterproofing products.

We believe in personal service and maintain a policy of professional supervision for every job. Time is important to everyone, and we at Rainbow Waterproofing & Restoration believe in working quickly without compromising quality.

With Rainbow, each job is unique and is carefully analyzed on an individual basis. After a survey of conditions, we advise our clients of the treatments that will satisfy both the conditions of the project and the cost considerations.
