"In the past we’ve avoided getting into agreements or contracts with our home security providers but felt comfortable and confident doing so with Safe Streets. Their monitoring and surveillance centers are nationwide and open 24 hours. They made the process really easy and informed us of all the benefits by being under monitoring agreement. Told both of our neighbors about our experience and they plan to sign up too."

"This was our second time using Diaz for our painting and home renovations. Once again he and his team did an amazing job. For this job, we had Diaz paint our hallway and master, redo our stairs and stair railing, re-finish and stain the hardwood floors, remove old baseboard heaters, and do a complete renovation of our upstairs bathroom (new paint, new floors, new vanity, new toilet, new lighting, new exhaust fan, etc.). He also helped haul out old furniture, removed an old (non-functional) oil gas tank from the basement, and replaced a broken storm door. One of the great things about working with Diaz is that the answer is always yes. His team is more than just painters - he has skilled craftsmen, workers with expertise in plumbing and electric, and everything else. There is no need to deal with anyone else. If you need something done in (or around) your house Diaz either can do it or has a guy. After contacting Diaz, he came right out for a free estimate. He listened carefully to what we wanted but also made a number of important suggestions to improve the results. Each day his team was hard at work - they were trustworthy and courteous, and cleaned up perfectly each day. Diaz goes the extra mile to make things convenient - including hauling away trash/junk, recommending a local showroom, and picking up materials that we had ordered for the job. As with any major project, there were a few bumps in the road. But Diaz worked through the curveballs with good communication. They finished on-time and on budget, and the results were perfect. If you’re looking for versatility, reliability, attention to detail, and overall excellence, then Diaz is your man ."

We are an all around commercial and residential construction company. Before me and my wife started S&S Construction, we were both working for large companies in the commercial construction industry. We have a lot of experience getting jobs done on time and on budget. I was a Forman for the last seven years that I worked for Finishes Inc. Everyday as a Forman I learned how to cater to a clients needs and make sure they were totally satisfied with the job they were paying for no matter what problems came about in the construction of the project. Any personnel that works for us will treat you with the upmost respect. Our expectations of our employees and suppliers are some of the highest in the industry. We practice a accident free work place, zero tolerance drug or alcohol use policy,and follow the OSHA, or MOSH safety regulations no matter how small the job is. If you choose to ever work with S&S Construction the experience will keep you coming back time and time again. 240-315-4737

"I have been in touch with Clint from S&S since October 6th. I want to start by saying that Clint has great customer service skills, but I am just not happy with the time frame or end result. When I initially reached out to him, I requested that he take a look at my stores rear door as it is decaying. He came out that same week, but I did have to chase him a bit for the estimate. Fast forward to Mid-November where I reached back out to Clint requesting that he come in to evaluate our front door now as we had multiple break in's and are in need of putting in place more security measures. He was finally able to come on December 2nd to evaluate the door and informed me that he would get me an estimate by the end of the week. I had to message him again requesting said estimate on Tuesday December 9th and he didn't respond to me until today, December 16th, to tell me that he won't be able to get the estimate to me until next year. Very displeased!"
