"Michael Ridgeway was wonderful to work with because he listened to how I wanted the gate to be finished so it would be structurally strong. I would hire him again without any question. Michaels helper that worked along with him worked very hard. I really appreciate their work ethics. Thank you so much Michael and Tommy! Sherie"

"I called to set the appointment.  they gave me a three hour time window.  the gentlemen showed up towards the beginning of the time frame.  they were very courteous.  They explained what they were going to do, how the equipment worked, and about how long it would take.  They cleaned my vents in a reasonable time.  They also vacuumed up all the spider webs around my furnace while they were down there (I have a stone basement so it is a never ending battle).  The next time I need my vents cleaned I will absolutely call them.   I have recommended them to everyone I know."

10 years experience half in service and repair work and the other half building commercial buildings or doing commercial tenant improvements. I hold Pro-Pex certification and Counterstrike Trac-Pipe(flexible Gas Pipe) certification while working in the area for over 20 years. I went to Granite Bay high school and have built great relationships with customers and suppliers over those years. I hold multiple commercial purchasing accounts with suppliers to enable me to purchase materials at the lowest Price and Best Quality. My company works locally and remains completely honest and straightforward so you get the best install and equipment at the lowest cost.

"We recently bought a house in Sacramento. During the last rainy season we discovered that we had a drainage problem: pools of water formed next to the foundation and water was running underneath the house via the crawl space depression. Over the years, the grade on the north side of the house had developed a slope toward the house (probably due to adding soil for gardening) and the old flexible corrugated downspout drain pipes had clogged or collapsed and didn't run to the curb. Hays Engineering fixed all that. The company owner, Josh Hays, kept us informed about the project schedule and was on site. They contacted utilities to mark underground lines. They regraded the north side of the yard and installed a drainage system consisting of seven collection points using smooth 4 inch drainage pipe (that can be cleaned out if necessary). The Hays Engineering crew used a laser level to ensure that the slope of each drainage pipe was correct. The terminal ends of the drainage pipes were fitted with pop-up drainage emitters. In-ground irrigation pipes were rerouted where necessary. Digging the trenches for the system was done very carefully and they hand dug when approaching an underground line. Mr. Hays and his team were friendly, professional, and answered all of our questions. Not only did Hays Engineering do an outstanding job, the cost was very reasonable. We highly recommend Hays Engineering and would use them again without hesitation."

"He was awesome.  He called back, but he was working in Reed field, North Carolina and he could not get to us for a couple of days.  By the time, he got to us we had already gotten the other estimates, and we were pleased with him.  Hampton guy was great.  He was really quick to get back to us, but he had other projects that he had already lined up.  The experience was very satisfactory.  He was very courteous, and prompt.  He was very honest in saying that he cannot get to us, and if we needed to have this work done now, then we need to have to get somebody else.  I appreciated that."

Basement Waterproofing FAQs, answered by experts

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.
