Here at Best Homes, our company is based on the belief that our customers' satisfaction is of the utmost importance. Our team is driven to meet your needs with professionalism, creativity, and efficiency. Established 2005. Owner: Jonathan Perez Office Manager: Paige Marie Campbell Project Manager: Jefry Perez
"Basement Project We absolutely love our new basement! I was very nervous when selecting the contractor for this job. I interviewed three contractors for the job, all seem very decent, but what set Best Home apart was Jeff Segovia. He designed the whole layout of our basement (we love it) and oversaw the entire project from beginning to end. The construction crews were very polite and friendly. Best Home did an excellent job and very flexible with many changes I had and they completed the job on time (took 3 months and exactly 1 week)which was amazing. I am actually hiring them again for additional projects. I highly recommend Best Homes!"

We take great pride in our top-notch remodeling services in Rockville and ensure that every project we do turns out perfectly.
"Our place had good bones but didn’t work for our daily life. Every room felt cut off from the next. Ben and Teddy from Top Remodeling sat with us and came up with a better layout without changing the size of the home. They moved the hallway, opened the living area, and added a custom touch in almost every room. They rebuilt the inside from the studs and used solid-core doors and clean finishes. We went with soft white walls, bronze handles, and natural maple cabinets. Now, it all feels open and calm. Every room has a purpose."

Building code requirements vary by location. In many earthquake-prone areas, seismic gas shut-off valves are mandatory for new construction and during certain renovations or property transfers. Local building codes may specify which valve models are approved for installation.
Even where not required by law, these valves are strongly recommended as a safety measure in seismic zones to prevent gas-related fires and explosions following earthquakes.
Many insurance providers recognize the safety benefits of earthquake valves and may offer discounts on premiums. The specific savings depend on your insurance company's policies and your property's location. Contact your insurance provider directly to inquire about potential discounts for seismic safety improvements, as offerings vary between companies and regions.
Licensed natural gas plumbers are the most qualified professionals for earthquake valve installation. In most states, plumbers must maintain specific certifications and insurance coverage to work with gas lines. These professionals understand local building codes, proper valve placement, and how to ensure the system functions correctly during an emergency. Always verify that your installer has the appropriate licenses before proceeding with installation.
When an earthquake valve activates during a seismic event, it automatically shuts off the gas supply to your home. After the valve has triggered, you'll need a qualified professional to inspect your gas system for damage before resetting the valve and restoring gas flow. This safety measure prevents gas from flowing through potentially damaged pipes or into your home when appliances might have been compromised during the earthquake.
