Great customer service! We used Alto for excavating our property for building a new home, building our septic and maintaining it and demolishing the pre existing house on the property. They are a top notch company and have served us well any time we have used them. I would highly recommend Alto.

We have used Allto Construction for over 3 years for all our septic needs and it’s been amazing! Angela from customer service takes care of all our issues right away and is always so sweet and helpful! JP who comes and services our septic makes sure everything is working and will only change parts if needed! Carl who pumped our system was so sweet to walk me through how our septic works! Highly recommend this company for their ethics and professionalism! All employees have been there a long time so that just shows the owner is treating them well!

Finally a company that knows there stuff when it comes to septic systems. I was have multiple issues with my septic system. Multiple pumps and guys just saying that you’re good to go. Then Allto comes out and completely clean out the tank properly and in about an hours time diagnose the issues. Fantastic work. These guys will have a life time customer. No doubt. Also the tech that came out to do the diag Jp was a very knowledgeable and friendly guy.

Allto construction replaced our old septic system (winter 2025) with a new upgraded elijen septic system. The process was very smooth, organized and completed in a timely manner even with the major snow storms that occurred during the job. JP was able to walk us through the upgraded system to be a solution to our futuristic backyard plans. The equipment operators John & Frank were amazing at their jobs, kept everything clean and organized around the yard, and kept us up to date with what was going on as the job progressed.

10/10 will be using Allto again for any future septic system projects that are needed!

Had a septic emergency on the weekend, called many companies and was left completely unimpressed- most couldn’t be bothered to even call back. Finally called Allto expecting the same, but instead I was met with great customer service- right from their office staff, to the staff who came out to my home that same day! Completely professional and pleasant! We are new to the home we are in and we have just found our septic company!

Allto Construction is a pleasure to work with! All their staff, in both the office and the field, help to make projects run smoothly! I've worked closely with their septic designers and it is always a smooth process.
