We work closely with each client to understand their unique needs and preferences, and our commitment to customer satisfaction means we won't rest until you are 100% happy with our work.

"I hired Hillcrest Landscaping owned by Saul Martinez to repair or replace our old sprinkler heads and pour some concrete to finish up a sidewalk. That was in September and I have regretted it since. Do not hire this company. He is not trustworthy. He left on a Friday, said he would be back on Monday to finish up the work. I know you don't pay until the job is done but I did it and I won't do it again. Lesson learned. He got paid to finish the job and didn't. No phone call from anyone from Hillcrest Landscaping. No one came to finish up the work he said he would finish. He has been here once since with the assurance that he would be back to finish my project and I am still waiting. No call no show, again. I now have to do it myself. Some of the work will have to be hired out. Even though I have already paid Hillcrest Landscaping for the work. DO NOT HIRE THIS COMPANY!! "

"I contacted M&J Prime Builders on a Sunday morning via an urgent request on Angi (Angie's List) to repair a leak in our backyard irrigation system. Javier contacted us immediately and arrived at our home in Concord with his business partner, Marcos, within 90 minutes. They were very attentive, professional, and accommodating, especially for our unexpected Sunday morning emergency. They not only repaired the leak but also addressed another issue that had arisen with our shutoff valve. Their estimate was very reasonable and accurate, and their work is top-notch. Javier is both a licensed contractor and a civil engineer. As a result, they offer a wide range of home improvement projects. I will be using their services again and highly recommend M&J Prime Builders"

Gas Fireplace Service questions, answered by experts

Removing a chimney is difficult. You may need to take it out brick by brick from inside the walls. If it’s part of the load bearing structure of the home, removing it becomes even more difficult. Chimney removal cost can range from $1,000 to $10,000, depending on the complexity of the job, and whether or not it’s load bearing. For this reason, many people will choose to remove the fireplace and seal the chimney at the bottom and top. You could remove the visible exterior section of the chimney at the roofline before sealing it, too.

Even though ventless fireplaces are safe to use overall, you shouldn’t let them run for more than a few hours per day. It’s also important to make sure the room with the fireplace is well-ventilated. If not, the water vapor from the fire could increase the humidity levels in your home, potentially resulting in mold growth.

In some cases, you can use a fireplace once the insert has been removed. However, before burning a fire, you must have a professional inspect it and the chimney to make sure they're functioning properly and no damage has occurred from removing the insert. That’s because using a fireplace without an insert could create fire hazards due to issues with airflow and heat dispersion, depending on the fireplace design and material. A professional can advise on whether you should make certain repairs or modifications before using your fireplace as an open hearth.

Professionals sweep chimneys and clear obstructions, using specialized rods and cameras to ensure safety and condition monitoring.

If you have a chimney, you need a flue or chimney cap. The right covering keeps rain, debris, and animals from getting into your flue or chimney and causing damage. A flue or chimney cap also provides fire protection. The mesh insert around the cap keeps sparks from flying out of the chimney and igniting leaves and other materials.
