Leading The way

Owned and operated by myself, Martin Egan, I started the company with just a laborer in 2000 and gradually added more full time employees throughout the years.


Breffni Construction is a fully licensed and insured construction company that does everything necessary for a potential project––from the foundation to the finish work. We also handle commercial work and have completed have completed several large projects for South Shore Hospital in Weymouth and Brockton VA Hospital. We are happy to provide as many live references from previous clients that a potential client may require.


Breffni Construction is known for attention to detail and NEVER leaves an unhappy customer, no matter what it takes. Reviews on Angie’s List and the Better Business Bureau will attest to this. Additionally, Breffni Construction buys and sells properties that require full gut rehabs.


This keeps all of the staff knowledgeable about new products on the market and in tune with what makes a good investment project, so we are able to guide clients on the dos and don’ts with a future sale in mind. .
