"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

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.

Completion time ranges from days to weeks, contingent on project size, environmental conditions, and regulatory approvals.

Excavation and grading are both generally necessary for designing your foundation, and leveling the ground where your foundation will go. These steps can also prepare the area by removing vegetation and anything else that could interfere with your home’s foundation.

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.

To locate an underground downspout, you should start by identifying where the above ground gutter drains. Look for an entry point, such as a pipe or elbow leading into the ground. Follow the surface path for signs like depressions, landscaping disruptions, or wet areas after rain. You can use a metal detector or plumber’s snake to trace the pipe underground. For deeper pipes, a professional locator tool or camera inspection may be necessary. Visual markers or utility maps can also guide the search.
