How can you prepare your property for excavation?

Clear your site of any trees, shrubs, or existing structures ﹣ within your capabilities! You can let Lambert & Barr know what obstacles may be in the way. We have the equipment and expertise to prepare your site for excavation to the full extent.

What are signs you need a new septic system?

If you are experiencing slow drains, sewage backup, foul odors, or pooling water on your land, you may need a new septic system. We can provide an assessment of your current system and check for signs of septic system failure.

Do you need a retaining wall?

You may require a retaining wall if you need help controlling downhill erosion or managing water runoff. If you are building on a slope or in a hilly area, you’re more likely to need a retaining wall. Our general contractor can help determine whether your project requires one, and if so, we can build it.

Do we provide foundation construction & excavation?

Yes. If you need to prepare your land for construction, we provide excavating services, foundation construction, septic system installation, and more. We have the expertise and capability to handle the entirety of your construction project.

“I just wanted to thank you for the very professional way in which you handled the replacement of our septic system. You did what you said you would do, when you said you would do it, which is what I expect from most people I have worked with time and again over the years, but is much more than most people manage. Of course, I appreciated your ability to get the job done quickly in the heart of winter, getting to an approved full system as we both wanted. What especially stands out, however, is the very nice clean up job you did on the work site, months later and exactly as promised after the weather warmed up. Thanks again.”
