"Couldn’t have asked for a more honest and trustworthy contractor. After letting my previous GC go, Mike and his team were a breath of fresh air. Extremely impressed and grateful for their work. Highly recommend. Should have called Twin Timber first."

"I hired Matt to prepare a site for a shed we have ordered. He replied promptly for a request for an estimate. He explained what needed to be done and gave me a fixed date when he could do the work. Throughout the project, he kept me apprised of the progress and explained the choices that needed to be made. I was impressed with the care with which he approached every aspect of the project. Just a great guy to work with."

"I had Ken come out to look at a stump removal and I mentioned a retaining wall project I needed to get done. Ken took some quick measurements and then came back again late that afternoon with his team and took more precise measurements. That evening I had a quote that was comprehensive and fairly priced. We quickly agreed on the project and date. Ken, Rowan and Roger showed up on time and completed the job quickly and efficiently. I would highly recommend McAdams Excavation and Landscaping for all your excavation, landscaping, and hard scaping needs. I am more than totally satisfied!!!"

Excavating FAQs, answered by experts

You should dig 3 to 6 inches deep for plastic edging. Dig as wide as you need to fit your plastic edging into it—2 inches is usually sufficient.

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 residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

Yes, you can install a trench drain if you already have concrete in your yard or garden. While it can complicate some aspects of the job and slightly run up the cost, it is doable. Residential trench drains can be easily retrofitted to outdoor areas with concrete without having to remove excessive amounts of your patio, pool area, or decorative walkways.

Underground downspouts refer to the sections of downspout extensions that lead away from your home and gutter system. While they cost more than traditional extensions, they can provide several benefits, such as less frequent damage and no need to move them for lawn care tasks. Whether they're worth it or not depends on your budget at installation time and how much convenience they'll add to your situation.
