"Konnaugh and his team were a pleasure to work with. They showed up on time, and after demolishing and removing a hot tub and a chicken coop, they left my yard practically spotless! They did such a great job, I would highly recommend them to anyone looking for junk removal or yard cleanup ??"

"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!"

"We hired Tyler and his crew from Quantum Contracting LLC to build a 10 x 12 pool deck and they did an awesome job. Hardworking, pleasant and professional. They cleaned up the area every night when they left and when the project was completed. Very skilled in their detail and carpentry work. We are so pleased with the end result and look forward to using it this summer. We would hire them again for any project and we highly recommend them. Paula and Stephen Russell"

"We had a water problem with water coming into our finished basement after a heavy rain. S.L. Dionne excavated down to the base of the foundation to fill a crack in the foundation, seal the crack, and cause any water coming near the house to run away from the house. Not only did they do the job perfectly, exactly on schedule, they re-landscaped the disturbed area so my front yard now looks better than before."

Excavating FAQs, answered by experts

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

The best type of soil to build on is a mixture of sand and clay, known as loam soil. Loam soil has the best combination of these soil types to build a foundation on. The clay particles help with water retention, so it won’t erode like sandy soil might, and the sandy particles help with drainage, so you won’t see unsafe soil expansion or have an increased risk of leaks from water sitting against your foundation.

There are many ways to cut through roots when digging, especially if your trencher doesn’t seem to be removing the roots. First, use a shovel to expose the roots. Then, use gardening shears to clear out smaller roots or a reciprocating saw to remove larger plant roots. If you plan on keeping the plant, avoid cutting any roots over 2 inches thick.

Yes, chipmunk holes may have two or more entrances. Chipmunks can create an entire network of burrows. Having multiple entrances makes it easier for them when trying to escape from a predator, such as a snake, or if an entrance collapses due to flooding. Each entrance leads to the nesting chamber underground, which is where the chipmunk spends the majority of its time sleeping.

There are several different factors that influence how long it takes to excavate. For a foundation, it could take anywhere from three days to three weeks. It can take even longer if you face weather-related delays or an inaccessible site that’s riddled with boulders and rough terrain. It may also take longer if you have clay soil, which is more difficult to dig.
