"I called a well known company to clean out my sewer line and they were not able to do so.  They told me I needed to jettison out the line as the next step and gave me a very high price.  I called my plumber who told me to call the Drain Company.  They could not clean out the line but recommended another company who they trusted.  I called the other company who cleaned out my drain for half the price of the first company.  The Drain Company called me to see how it went.  I will definitely use them in the future to keep my sewer line cleaned out earlier in the game so I don't have this problem again.  The cost the same as this well known company and were helpful instead of trying to intimidate me.

"Leaving this review in regards to the excellent job that was done by U.S. Home Developers. We had them remodel both our driveway and our roof. When we first called in they mentioned that they were first going to send in their project manager. Upon meeting him and going over all of the plans we immediately felt that we were in good hands. The project ended up coming out great and our home looks better than ever. Thank you!"

"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.

"not that great. basically paid $99 to get an estimate. included cleaning roof and minimal repairs. took a while to get appointment, and then when they came, they didn't even do the work! gave a really big estimate and then re-seheduled to have someone else do the work. they wouldn't totally replace the roof, gave different estimates to repair, I went with a different company to do a full roof rplacement."

Excavating FAQs, answered by experts

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.

Above ground pools are not buried in the ground. Typically, above ground pools are semi-permanent. One reason they’re more affordable is that you don’t have to dig for an inground pool and pour concrete or another material. However, you can choose to install a semi inground pool, which is a hybrid between the two.

Downspouts should be buried at least 5 to 10 feet away from your foundation. This can vary depending on your local building codes, soil type, and property slope. The main goal is to ensure water is directed away from your foundation.

Most professional excavation teams will charge between $8 and $15 per cubic yard. Calculate the cost by finding the volume of your pool—width x length x depth—and dividing it by 27. Then, multiply the price by the cubic yards from your equation. Budget for complications like a rocky lawn, hard-to-access pool area, or high local labor prices.
