"Jared did an amazing job and was very thorough in his work. He prepared the site work for a retaining wall behind a newly installed pool and the attention to details in where he placed the drainage was perfect. The following week we had a tremendous amount of rain and it kept all that water well away from the pool. Took a lot of pride in the work he did for us and can not wait to work with him again on our next project!"

"We had an amazing experience with Twin Timber! They completed a full kitchen remodel for us, and we couldn’t be happier with the results. From start to finish, they were professional, reliable, and paid incredible attention to every detail. The quality of their craftsmanship is outstanding, and they made the entire process smooth and stress-free. Our kitchen turned out even better than we imagined, and we’ve received so many compliments on it. We highly recommend Twin Timber to anyone looking for a beautiful, high-quality renovation. Thank you for making our dream kitchen a reality!"

"Project - Complete the work of replace siding and windows from a job previous contractor left half way. They are extremely professional, friendly and reliable. They delivered everything and more they promised on time. We were remote. They kept us informed every step of the job. We had a very fussy tenant in the property. The crew had to go in to the house. We were concerned how it will work. The tenant was very happy with the work they did and how they cleaned up afterwards. We highly recommend them. We will ask them to come back and do our decks once the weather gets better."

Excavating questions, answered by experts

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.

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.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

Most states do not require excavation companies to hold specific licenses, but many require at least a contractor’s license. Additionally, heavy equipment operators require a special commercial equipment license to operate machinery required for excavation. You can use Angi’s contractor licensing tool to confirm that an excavation company you’re considering hiring is fully licensed. You should also make sure that the excavation team is fully insured before allowing them to work on your property.

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.
