A cramped crawlspace can limit your home’s functionality and create long-term moisture and air quality problems. We transform tight, inaccessible crawlspaces into clean, usable areas that improve your home’s efficiency and give contractors the access they need to do their best work.

Our crawlspace excavation process begins with a thorough evaluation of your existing foundation, soil conditions, and drainage needs.

Basement & Crawlspace Dig Out FAQs

What is basement and crawlspace excavation?

Basement and crawlspace excavation involves removing soil from beneath or around your home to create usable below-grade space. This can mean digging out a new full basement, lowering an existing crawlspace for better headroom, or expanding access for utilities and foundation work.

How long does a basement or crawlspace dig out take?

Most projects take anywhere from a few days to a couple of weeks depending on the size of the space, soil conditions, and access to the site. We’ll give you a realistic timeline during your free estimate consultation.

Can you excavate under an existing home?

Yes. Excavating beneath an existing structure requires careful planning, proper shoring, and experienced operators — all of which our team is equipped to handle. We work closely with structural professionals to ensure your home stays safe throughout the process.

Do I need permits for basement or crawlspace excavation?

In most cases, yes. Permits are typically required for below-grade excavation projects in Boise and the surrounding Treasure Valley. We’re familiar with local requirements and can help guide you through the permitting process.

What is underpinning and do I need it?

Underpinning is the process of strengthening and extending your existing foundation so excavation can safely occur below it. Whether you need it depends on your foundation type, soil conditions, and the depth of excavation. We’ll assess this during your site evaluation.

How is soil removed from under my home?

Soil is excavated using compact equipment suited for confined spaces and transported via conveyor, bucket, or small haul vehicles to a staging area. It’s then loaded and hauled off your property completely.

Will excavation damage my existing foundation?

When done correctly, no. Our team takes every precaution to protect your existing foundation, including shoring, monitoring, and staging excavation in a controlled sequence. Safety and structural integrity are always our top priorities.

What is the difference between a full basement dig out and crawlspace lowering?

A full basement dig out creates an entirely new below-grade living or storage space, typically 7–9 feet deep. Crawlspace lowering simply increases the clearance height of an existing crawlspace — usually from a few inches to 3 or 4 feet — to improve access and functionality without converting it to full living space.

How do I know if my crawlspace can be lowered?

Most crawlspaces can be lowered, but factors like foundation type, soil composition, water table, and drainage all play a role. A site assessment is the best way to determine what’s possible on your property. Contact us for a free evaluation.

What drainage solutions do you recommend after excavation?

We commonly install or prep for sump pits, French drains, and perimeter drainage systems as part of the excavation process. Keeping water out is just as important as the dig itself, and we plan for it from day one.

What does basement excavation cost in Boise?

Every project is different based on size, depth, soil conditions, access, and drainage needs. The best way to get an accurate number is to schedule a free estimate — we’ll assess your property and walk you through the costs with no obligation.

Can you add an egress window as part of the project?

Absolutely. Egress window excavation is a natural add-on to many basement projects and is required by code if the space will be used as a bedroom or living area. We can include this in the overall scope of your dig out.

How do I prepare my property for basement excavation?

Clear the area around your home’s foundation of any furniture, landscaping, or obstacles that could interfere with equipment access. We’ll walk you through any specific prep steps during your pre-project consultation.

Do you work with foundation contractors and structural engineers?

Yes. Below-grade excavation is a team effort, and we regularly collaborate with foundation specialists, structural engineers, and general contractors to ensure every project is completed safely and to code.

Can this service be done on commercial properties?

Yes. We handle basement and crawlspace excavation for both residential and commercial properties throughout Boise and the Treasure Valley. Contact us to discuss the specifics of your commercial project.
