"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).

"Absolutely In love with the work that was done at my place! The result was even better then i had imagined, I had my bathroom and kitchen done. I have always been terrified of contractors as in the past I was ripped off, but this is not the case they communicated with me every step of the way and made this an enjoyable experience for me. I would definitely recommend them to anyone looking to remodel or have work done in there home! Thank you again to US Home Developers Inc you guys did an incredible job"

"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.

"We waited to review our project 1 year after completion to be sure that all was well. We are very pleased with the final result. Our only mishap was having miscommunications with B&B when we requested follow up 4 months after project completion – our issues were resolved with a factory representative. No hard feelings. How It Went- Workers were professional and competent. Building on an existing slab is extremely challenging – because the slab slopes away and down from the house – 2 angles that need to be countered when leveling windows and doors etc. When corrective rework was needed (to compensate for a 2 inch site deviation) the team didn’t hesitate and B&B came up with an excellent solution. We retained the exterior stucco exterior of our house for the room and they finished the wall beautifully – it required a lot of fine and patient work. We asked for an 18 inch deep exterior pad – which accommodates a doormat and our foot print. It was done this way – although there was initial push back on this request. We also involved our own electrician, who is familiar with this old house – and we came up with an elegant solution to connect to our home. After project closure, we delayed evaluation until things settled out. Over the next few months, some of the sliding windows became increasingly difficult to open and close – and during an extremely fierce and long rainstorm we experienced a leak coming from one corner of the enclosure. We immediately spoke with B&B. With miscommunications with B&B, we resolved our issues with a factory representative in a single short visit: they added weep holes to the exterior, caulked, replaced a window roller and adjusted windows and the screen doors. We are very pleased with the final result. And so are our kitties."

FAQs for excavation projects in Diamond Bar, CA

Unfortunately, some plumbing scenarios, like a broken sewer pipe repair, will require excavation to complete the job. Plumbing excavation costs range from $30 to $70 per cubic foot. However, if you need additional trenching, expect to pay an extra $4 to $12 per linear foot. Keep in mind that these costs are on top of the plumbing repair costs, and they don’t account for labor costs. Consult your excavation specialist to determine an accurate estimate for your job.

The average cost for pool excavation is $2,500. This cost can range from $450 to $4,500, depending on the pool shape and size, time of year, and any need to move buried utilities. 

When excavating for your pool, you might have to move existing utilities. You can expect to pay an additional $15 to $25 per linear foot to move gas lines. To move a septic system, it’ll cost an additional $2,000 to $20,000. A pool that is 10 feet by 12 feet averages $450 to excavate, and a 20-foot-by-40-foot pool averages $3,020.

The cost for residential excavation is $3,200 on average, ranging between $50 and $200 per cubic yard. Total costs could range from $500 to $15,000, depending on the project type, yard size, and soil type. 

When a project needs an excavator, the contractor will subcontract one as part of the larger project. If you hire an excavation specialist, you can expect to pay between $40 and $180 per hour. When excavating, if you have soil with excessive rocks or clay deposits, expect an additional cost of $200 to $1,200.

Warm weather seasons like spring and summer are ideal times to excavate due to the ground being softer and easier to dig through. However, it is important to note that bad weather, like heavy blizzard conditions or torrential rainfall, can prolong the project length, increasing costs. That’s why it’s best to avoid excavating during winter or hurricane season, depending on your home’s location.

While completing an excavation project yourself is possible, we don’t recommend it. You’ll likely need to buy or rent the equipment necessary for the job. This equipment costs as $100 per hour or $2,200 weekly, increasing by as much as 50% for larger jobs. 

In addition, completing an excavating job yourself poses a safety risk. If proper marking hasn't occurred, you risk hitting buried cables and other critical piping, like gas and water lines. Additionally, if working with excavation equipment, you’ll need to steer clear of any overhead wires. Leaving this project to an excavating professional is best.
