"Got a reasonable quote from David to remove an above ground pool, which was taken out efficiently in the morning, and then decided to have them remove a pool deck on short notice the following day. Kathy handled the arrangements nicely."

"I hired Barletta Excavation to do some outdoor drainage work around my pool deck. Alex the owner came out to my house and was very friendly and easy to work with. He was able to get the job done quickly and he communicated with me throughout the entire process to let me know what was going on. I would highly recommend Barletta Excavation!"

"Honestly, we cannot say enough good things about Drainage Pros. They are professional, competitively priced, trustworthy, and - most importantly - excellent at what they do.
We moved into a 1920s home with major drainage problems. Four of the six original underground drains that collected water from the downspouts were nonfunctional. Our home also sat low on the property, and when it rained water flowed across our driveway, over the patio, and into our basement by seeping over the foundation. It looked like a small river coming toward our home and disappearing underneath.
AJ responded quickly to our initial inquiry and met with us on site to discuss the project. He listened carefully to our observations while assessing the driveway, patio, and grounds before sending us a detailed proposal the next day. The proposal listed several different stages and options, which we continued to discuss with him at every step of the project. AJ was always very  knowledgeable, communicative, and professional, responding to our many questions and concerns thoroughly and patiently (even when we asked the same question multiple times). Ultimately, Drainage Pros stood by their original proposal, working within budget, and they even guaranteed their work (although we don?t expect we?ll be needing the guarantee).
They tore out and had the old driveway re-graded and repaved, installed a channel drain behind part of the home, and laid pvc pipe along the entire perimeter to collect water from all six downspouts. They ran the pipe under two bluestone patios and walkways, all of which they reset carefully. They connected the pipe to our main sewer line, which required six foot plus excavations. Lastly, they reseeded the lawn (which returned nicely), and basically restored the grounds to their original condition. The paving company they coordinated with was also excellent, and they worked hard at communicating with each other to ensure that the project was completed to our satisfaction.
Personally, what I most appreciated about working with Drainage Pros is that AJ did not trouble us with all of the things that could possibly go wrong while performing such a major job like excavating and tapping into the main sewer line. He simply assured us calmly and professionally that he and his team could do the job, and they did. Perfectly.
We had previously discussed the job with a completely different (and also highly rated) contractor who appeared flustered by our drainage issues and, after charging us >$1,000 for an assessment and cleaning, was unable to offer us a written proposal or estimate without further ?diagnostics?. Do not waste your time and money, like we did. Just hire Drainage Pros, and they will get the job done.
We now have absolutely NO DRAINAGE ISSUES and strangely even look forward to when it rains so we can see how beautifully the water flows down the driveway, into the drains, and away from the house. If you are on this site searching for a drainage specialist, perhaps you can appreciate this.

Excavating questions, answered by experts

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

Because decomposed granite is a durable material, a crushed rock or gravel base is optional as long as the DG is properly installed and compacted. However, installing a base is a good idea because it will ensure proper drainage and stability and act as a weed suppressant (although you may still occasionally have to pull weeds). Installing an adequate base can also increase the durability of driveways and walkways. If you forego the paver base or gravel underneath, line the area with landscaping fabric to avoid weeds.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

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.

Maintain open communication and address issues as they arise, ensuring contract terms cover potential delays.
