Capturing the Hearts of the Best Customers for Life


Customer Satisfaction

For us, this one is obvious, but our world is always changing. Our reputation is everything to us! We will not put our reputation in jeopardy to make a quick sale. We’ve been in business for four generations and plan to be for at least four more and we can’t do that if we do not treat people fairly and honestly.


Summers & Zim's, Inc. Wall Decal

We pride ourselves on our efforts to be the best home service provider in this area. Whether that means technical competence, the latest technology in tools, response time, follow up, clean uniforms and trucks, etc., we want to strive to always be our best and be excellent in everything we do.


Summers & Zim's Historical Banners

Like those that have gone before us, we are not averse to hard work! Our trades sometimes involve tight spaces, hot attics, dirty sewers and sometimes we need to stay late to “get the job done right”.
