About Claddagh Construction Services, LLC

Rooted in their strong Irish heritage of hard work and kindness, Claddagh Construction set a standard doing repair work and remodeling for members of their own community. The mindset has always been family oriented. With this mentality, Dan Jr and Dan III have been able to pride themselves on listening to and understanding exactly what their clients are trying to accomplish.

Baltimore County Roofing Company - HAAG Certified


It?s common sense: building materials don?t last forever. Throughout a product?s life cycle, its ability to keep you dry and insulated can be affected in a variety of ways. The natural process of weathering and aging can be accelerated by a number of factors, such as the damaging effects of hail and wind or other non-natural (mechanical) forces.

While these issues are very different in origin, on the surface they can look quite similar. Determining the true cause of an issue with confidence requires advanced knowledge and thorough investigation techniques.

This is why Haag Certification is so valuable. Haag Certified Inspectors are not beginners in the field. They are adjusters, estimators, home inspectors, roofing contractors, consultants, and other industry pros who have fine-tuned their inspection skills to find damage where it exists.
