We are a locally owned and operated company that values honesty and integrity and treats your home as if it were our own. We offer a variety of painting services that are customizable to each individual project. You will find us to be competitively priced, paying close attention to the details of each and every project that we are involved with. We look forward to building lasting relationships and guarantee your satisfaction!

"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 ."

"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence. Time sensitive materials which added to homeowners to-do list. Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"
