"Quick response with quote, which was really reasonable. They were able to complete the project right away. I had them remove glued down wood flooring, which is really difficult. A couple hours after they arrived the area was cleaned and ready for install. Will hire again for other projects."

"Called Drainco out for clogged drain(s), and was a little concerned that an AGENT ROOTER van pulled up, but Eric and his assistant, who arrived within the time frame, assured me that they work closely with Drainco, and went to work on what was a mess of roots in the main line. None of the standard clean-outs were usable, so they had to remove both toilets and snake from there. I was there, so I could see how difficult it was. I knew my plumbing needed a major overhaul, but until then, I'm grateful that Eric kept at it until I at least had toilets that flushed! The bill was very reasonable and they left the house clean. Will definitely use them again (but hopefully not too soon).

"They had done roof repairs for us in the past, so we hired them to do painting (inside & outside), stucco work, refinished our front door and tiled a bathroom. They always showed up on time every morning (it was a 10 day job). They worked throughout the day. They were great at making sure to seal off the work areas so they didn’t make a big mess & they cleaned up after themselves. Friendly crew, felt comfortable having them in my house. Excellent work results."

"I received 3 bids for this project.  From the very first interview with Roei, a partner I was impressed with his ability to advise on some ideas to save money and make the kitchen more efficient, he was very professional and never pushed me.   I hired him to start 7/31/13, he quoted 2 weeks, and it was completed in 2 weeks, and the cost was as quoted.   This was one of the best renovation experiences I have had in the 40 yrs I have lived in this house.   All the workers, were polite, on time, cleaned up after, and did really good work.  I would hire Best Builders again for any home projects and recommend them highly to anyone else looking for a good experience in renovating any part of their home.

"From meeting a staffmember in their showroom, to having a rep. come out and discuss a plan/take measurements/write out a contract, to the first crew that took down the old cover, to the next crew that installed a new patio cover/awning, to the final detail crew, and finally the owner, Jeff, coming out to inspect, all went very well. They did excellent work, were ontime, cleaned up, and left us with a very nice new alumawood patio cover and awning. Would recommend this company to anyone."

"Ricardo Guzman arrived on time and performed the work in an expert, professional and clean manor. He went the extra mile and corrected some sloppy work the electrician did which loosened some roof tiles. Ricardo even painted all the pipes so they would be consistent! He cleaned up all the gutter leaves and swept around the area he worked. He then provided pictures of all the work he had done. THIS COMPANY IS GREAT! THEY PROVIDE PICTURES OF THE ROOF AND WHAT NEEDS TO BE DONE THEN THEY PROVIDE AFTER PICTURES!!! When we need our roof done which is hopefully not soon, we will hire them. I will hire them to do roof maintenance (gutters etc) on a regular basis. The whole process from beginning to end was great!!"

Excavating questions, answered by experts

Trenching is a specific kind of digging. Trenching means digging a depression in the earth that’s deeper than it is wide, often with heavy machinery. Digging refers to any kind of removal of earth in order to create a human-made depression, hole, or cut in the earth’s surface. You can dig with big tools or even with just a hand shovel.

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

Most states do not require excavation companies to hold specific licenses, but many require at least a contractor’s license. Additionally, heavy equipment operators require a special commercial equipment license to operate machinery required for excavation. You can use Angi’s contractor licensing tool to confirm that an excavation company you’re considering hiring is fully licensed. You should also make sure that the excavation team is fully insured before allowing them to work on your property.

Some two-in-one tools and machines do both jobs, and those could be the right solution for smaller residential projects. However, the phrase “use the right tool for the job” definitely applies to digging. For the best results, get two separate tools for your trenching and landscape edging projects or call a pro to take care of everything for you.

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.
