"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

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Yes, you can enclose your crawl space. Enclosing your crawl space can promote energy efficiency and reduce the risks of pests and mold by limiting factors like humidity. It can also reduce heat loss, which is why doing so for the winter can make your home more comfortable.
