"Great service, very fast, friendly and great work! We were having the ceiling of our garage cut through to the attic, adding expanding stairs and having boards put in the attic so we could use it for storage. We were informed every step of the way. The end result, a great new storage space that is easy to access (and it looks great)!"

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"I found these company online and I hired them to replace all the existing windows and patio doors with new fiberglass (Milgard) Ultra windows and a double French door from them a few months ago for our renovation. They provided us with an awesome price for the windows and doors themselves and for the labor of the installation as well. The representative that I spoke to was very professional and he came over to my house on the time and day that was scheduled ahead of time via the office. The people that we were involved with (including the installers and the sales man), was definitely outstanding. We had a minor issues that accorded during install, and they provided awesome post-sale support as well. I recommended them to all my friends and family as a great company for any energy efficient products. They are fantastic. And have some Sunday hours, which is absolutely a great help. We purchased 2 additional exterior doors from them and this was an add on that we decided to do in the last minute and after the work was stated. We were sure that they won’t be able to do it during the same time… but they did it and it went so smooth and excellent. Should've gone to Landmark construction energy crew for those too. You can shop with confidence with them!"

French Drains questions, answered by experts

To unclog a plumbing vent, you first need to locate it. Look at your home's roofline. The plumbing vent will be a vertical pipe sticking straight up from the roof. Since this pipe runs all the way to the main drain underneath your house, you should also be able to find it in the attic.

There are several common signs that your main sewer line may be clogged. Key indicators include multiple fixtures in your home draining slowly, gurgling sounds coming from drains or toilets, and water backing up into showers, sinks, or toilets. You might also notice water backing up from the plumbing system's drain cleanout, water in your basement drain, or unexplained wet patches on your lawn. Foul odors, such as the smell of raw sewage or rotten eggs, are another common symptom. The most reliable way to confirm a main sewer line clog is to hire a professional plumber to perform a camera inspection.

Even if the shower drain doesn’t seem clogged or dirty, plan to clean it out about once per month—or more frequently if you or your family shed a lot of hair. It’s a good practice to remove any hair from the drain on a daily basis, as hair can accumulate fast and cause clogs in no time. You may also want to have a plumber thoroughly clean the drains in your home once every six months.

Start by unscrewing the overflow valve, which is located on the wall of your tub between the floor drain and the tub spout. Gently insert a plumbing snake down into the pipe, move it back and forth, and pull it out. Remove any hair, debris, and soap scum that comes out with it. Repeat the process until the snake comes out clean, and then reinstall the cap on your overflow valve.

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.
