"Irish and his associate Ryder were very good at communicating, even over a weekend, and although I initially thought the project was an easy drain clearing, 2 other plumbers failed to come up with an appropriate plan. Ryder made every effort to find a cheaper way to solve the problem, and only when those did not work, did he resort to a more complicated solution and at that stage he also worked to help keep our costs down. I appreciated the timeliness, thoughtfulness, and his clear and precise communication which also highlighted how experienced he was with this particular plumbing issue."

Business began in 1980, serving the Long Island, New York area. Relocated to southern California in 2001. Licensed over 35 years as a remodeling contractor. I assure complete customer satisfaction by personally working on and/or managing every project.

"Robert is the best contractor we’ve ever had! His attention to detail and his craftsmanship are stellar. Over the years, he has redone our kitchen, our bathroom, and recently he built us a loft bedroom in our daughters’ room. He raised the ceilings from 8 to 12 feet and the results are amazing! He built us a beautiful hard maple ladder from scratch and made a metal pipe railing for the loft as well. He added lighting and plywood in our attic for easy storage. He added a ceiling fan and new electrical/usb outlets throughout. He even added fun led color lights under the loft bed to add a cool lighting effect to the room. My daughters absolutely love their new space! We also had him design and build us a gorgeous floating bookshelf for our dining room and we could not be happier with it! It’s so amazing to have a beautiful space to display our books. We would 100% recommended Robert for all of your remodeling projects!"

"Kelly from Castle Plumbing was phenomenal from start to finish. He came out to assess the issue, told us the problem, quoted us a price, and was back quickly to fix the leak. He showed me the broken pipe he had fixed and charged us exactly what he had quoted. He was in and out in about an hour, and it was not an easy space to work in under the house. Kelly was very responsive on the telephone, and he was super professional and polite! We will be hiring him to install a tankless water heater for our house. Great service!!"

Excavating questions, answered by experts

Excavation is priced in cubic yards, so you’ll need to find the volume of the area in order to calculate costs. Multiply the length, width, and proposed depth of your excavation site, then convert it into yards to get the volume. Multiply this figure by the price per cubic yard.

Most homeowners can measure by hand to get a rough estimate, even if it’s tedious. You may want to pull out a tape measure or use a string to help mark the area.

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.

The depth of a septic tank’s drain lines is between 18 and 36 inches underground. These pipes are filled with perforations and surrounded by sand, gravel, or a combination of both, as both materials help filter wastewater. While some pipes are buried closer to the surface, this can create problems unless the soil is compact and doesn’t shift much. 

You do not have to dig footers for a deck as long as it meets local code and holds up to weather in your area. If you live somewhere that experiences high winds and earthquakes, you may need to dig for your deck posts. Deck blocks, post anchors with base plates, and helical pile systems are the three no-dig deck post options you can choose from if local code permits.

Directional drilling is complex and requires training to use the advanced machinery. It can be challenging to monitor the position of the drill since there’s no direct line of sight. Directional drilling can also be more expensive with a cost of $10 to $30 per linear foot compared to $5 to $12 per linear foot for trenching.
