"Provider was prompt, professional and friendly.  Arrived at the agreed upon time for a free estimate and performed work same-day after we agreed to the price.  He stuck to the price despite taking longer than expected and more work than usual due to worn-rusted pipes in my home.  Cleaned-up after himself and left no sign that work was done other than our new, working toilets.  We are very pleased and reccomend McDonagh & Sons Plumbing & Sewer Inc.

Excavating questions, answered by experts

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

The best method for digging a trench depends on the scope of the project. For a short, shallow trench (less than 2 feet deep) in light, soft soil, digging by hand may be sufficient. However, digging by hand is labor-intensive, so consider the effort required. A machine trencher is the better option for longer trenches (over 100 feet), deeper ones, or when dealing with difficult soil conditions, such as rocky or hard ground, or obstructions like tree roots. A machine can save significant time and energy in these situations.

The cost to repair a crawl space runs between $1,500 and $15,000, depending on the extent of the damage. Major flooding or water repairs can cost up to $10,000 for removal and repairs. If you simply need to clean your crawl space, expect to pay between $2,000 and $6,000 for a major cleanout. Replacing a crawl space beam due to rot or damage can cost between $1,500 and $5,000, while removing and replacing damaged insulation costs between $1,000 and $4,000.

If you have a broken sprinkler pipe underground, there will be some signs you can easily spot to locate it and take action. These include leaks, water spouts, flooding, consistently damp areas on your lawn, low water pressure, and grass around the sprinkler head that’s taller and darker than anywhere else in the yard. 

If there are no obvious signs of a broken pipe, you can use tools such as water leak mics, leak noise loggers, audio devices that record leaks, and acoustic testing links. 

Broken pipes can lead to uneven watering, plant damage, and higher utility bills. The longer you wait to fix them the more the repair cost may be.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.
