Customers say: Super punctual

"Wow! Rick is the best! He is the most responsive contractor I've ever seen, answering phone calls and messages and arriving promptly to begin the work just when he said he would! I had gotten multiple quotes for this job and he was the only one to really stand there and think about how it would look and any problems that they might run into. He had a crew of 5 that worked 6 days on removing an old rotten wood retaining wall, cutting it up and disposing of it, excavating a massive hill to add more flat space to the yard, and putting up two retaining walls with french drains. The crew arrived very early each day but were not loud, waiting until well into the morning to begin louder tasks like cutting the blocks. They did everything so beautifully and skillfully; my yard is totally transformed. I would definitely hire them again for any future needs! I could not be any happier with the outcome of the project! If you have a project, go with Rick Page Landscaping!"

"Tom from Metcalf plumbing did a great job. First, he came out on a Sunday morning to fix an ongoing leak . He immediately knew what the issue was, had the part and finished the job under an hour. He also made adjustments to our water pressure settings to prevent problems in the future. Tom was professional and pleasant. I would definitely contact him again."

French Drains FAQs, answered by experts

Chemical drain cleaners can work to clear clogs in pipes, but their use should be approached with caution. These harsh chemicals can damage pipes over time, and they can also harm the environment. Use them sparingly and consider alternative methods such as using a plunger or a drain snake. If you have concerns about a persistent clog, it's best to consult a professional who can safely and effectively address the issue without causing further damage to your plumbing system.

You can unclog a double kitchen sink by plunging the side with the garbage disposal. Cover the drain hole on the other side first to avoid creating a mess. Plunge up and down until the water starts to drain. You can also pour in baking soda and vinegar to try and dissolve a clog. 

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.

Some homeowners use additives every month to help septic system performance, but according to the U.S. Environmental Protection Agency, the effectiveness of septic system and leach field additives is unknown. Further, additives made with organic solvents or alkali chemicals can actually be harmful to the necessary bacteria in a septic system.

Professional plumbers use many high-grade chemicals to unclog drains. Many use hydrochloric acid, known as muriatic acid, when it comes to extreme blockages.
