"I hired Andy and his crew to clean my windows this spring and I could not be happier. They did an outstanding job, my wife and I are extremely pleased. Great value for the service provided. I definitely be asking them to come back again when I need their services. I would highly recommend Andy and his company for their cleaning services. Very courteous and professional.

"Overall, went well although project from start to finish took a long time (not entirely due to Waterscapes).  I would have liked if they could have coordinated the railings as once the stairs were done it took another 6 weeks to get new railings installed.
Bottom line, stairs and walkway look great."

"We have had an intermittant water problem in our basement primarily when it rains heavily in the Winter.
I was very happy with the quick response from Mike Sears when we initially called to ask about repairing a water leak problem in our basement.  Mike explained how his proposed solution would work to alleviate the water problem. 
Mike left us with a detailed estimate and informational materials about the proposed repair.  He also explained what wasn't included in the job such as tearing out the current sheetrock, insulation and framing from the wall.  I did  this part of the work and the reconstruction after the drain had been installed.
We spoke to Mike a few days later, agreed to the price and set a date for the repair.
On the scheduled date, two of Mikes employees arrived on time and began to prep for the repair.  They did a good job of hanging plastic sheeting around their work area so that the dirt and dust would not get into the rest of the basement.
We had discovered a crack in the basement wall which wasn't visible when the original estimate was given.  Scott Lee gave  us a written estimate to repair it with carbon-fiber cloth and sealant.  While this was an unexpected expense, there was no reason to put in a drain and leave a crack in the wall.
Taking out a basement floor with a jackhammer and installing a drain is a hard, dirty job.  Scott and his co-worker completed this job in about 6 1/2 hours including the additional work for the wall crack.
They did a good job of cleaning up the old concrete and all working materials 
Scott explained how the pump would work when the water table under the house rose.  
My only issue with quality was the uneven concrete finish work on the basement floor above the drain.  Because this was leveled by hand, there is a somewhat noticeable depression in this area of the floor.
Overall, I am happy with the work and looking forward to a dry basement when the rains come this spring.

Excavating FAQs, answered by experts

Completion time ranges from days to weeks, contingent on project size, environmental conditions, and regulatory approvals.

The digging depth will depend on the size of the trencher you use. Even smaller units can dig up to 4 feet deep, which is plenty for a DIY job. However, much larger trenchers can reach a depth of 18 feet and are better used by a team of pro contractors, not a single DIYer. As with all home improvement projects, use the right tool for the job and proceed with caution.

The easier way to find buried sprinkler lines is to use the plan from the professionals who installed the system. If you don’t have professional plans, listen for running water on your lawn when you turn on the system. You may also spot wet areas, giving you an idea of where the heads are. Once you find the sprinkler heads, you’ll likely be able to connect the dots between them, revealing the system below.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables.
