Maloney Construction put helical piers around our granny unit which is built on slab in Bennett Valley Santa Rosa. There was a large crack above a door jam prior to the piers.

 I was impressed that after the Napa earthquake the granny unit was rock solid with no changes. 

 Thanks for the good work!!!.

We hired the professional services of Maloney Construction to install ~200 helical piers for a solar installation in Hidden Valley Lake. The installation and design required a high level of installation accuracy. Site conditions presented challenges ranging from required dust control permits and contaminated spoils removal to varying site contours and the need for a level installation over several hundred feet.

The use of the helical piers and attention to detail from Maloney Construction were instrumental parts to the project’s overall success. The tight timeline and large quantity of product presented many challenges, all of which were handled professionally and according to contracted guidelines. We hope to use Maloney Construction in the future for additional helical pier solutions.

We were faced with a difficult installation. This was a retrofit foundation upgrade, so in addition to working underneath an existing an existing structure, we had to deal with a steep slope, soft soil access and a nearby perennial stream. Maloney's light trucks and small trailers had little impact on the soft soil approaching the site, and no drilled piers meant no spoils, thereby protecting the nearby stream and eliminating the costs associated with the subsequent spoils removal.

Another challenge was a new hillside foundation weaved among 300-400 year old Redwoods in a privately held old-growth forest. A standard foundation would have caused much damage to the sensitive root system, but the helical piers and their precise placement enabled us to tie-beam along the surface without excavation, gave us the foundation support we needed, and did it with minimal impact to the topography and the sub-surface root system. And no heavy, expensive pier spoils to deal with.

No heavy equipment, no spoils, minimal environmental impact, much faster completion time, and thousands less than a standard drilled pier installation. These are the reasons that I favor the Helical Pier System, and why I will continue to use Maloney Construction for all my engineered foundation projects.

Thanks Sean!

Sean Maloney was instrumental in keeping our project running smoothly while re-leveling the downside slope of our house, keeping it from slipping.

He was professional and kept the crew on the time schedule, making this a painless project for us, as it was completed promptly. We were never inconvenienced or had to move from our house during the construction. Thanks again, Sean, for all your hard work.

We highly recommend Maloney Construction, Inc.

I highly recommend Maloney Construction. I have utilized their services for installation of Helical Piers in a wide variety of conditions including all new construction, underpinning, and tight access, with site/soils conditions varying between hard rock, soft/steep embankments, ponds and deep old fill soils.

They are neat, clean, polite and professional, focused on providing a quality installation with excellent customer service and support. They provide quick follow up and are excellent at helping out with un-foreseen conditions and deadlines that may arise.

I greatly recommend considering using the services of "Maloney Construction, Inc." for the following reasons:

  • Sean Maloney (the owner) is very knowledgeable in foundation issues.
  • Realizing that building foundations are of primary importance, they do not hesitate to overbuild. Very often steel piers are installed to refusal.
  • Their prices are generally below the competitors.

Maloney Construction has a crew of experienced people. They do not hesitate in contacting me on time if discrepancies arise.

I am a license structural engineer who has designed several projects built by Maloney Construction. As such I feel very comfortable knowing that a serious organization is in charge of building what I engineered

I was very pleased with the professional and timely performance by the Maloney Construction crew and highly recommend the company for challenging foundation jobs. Our project involved the complete replacement of foundations under a two story frame building located on a bluff shelf bordered by steep descending dune bluff face on one side and an ascending slope on the other, with limited access from the road.

Maloney Construction was brought in to raise the house 6 feet, remove the existing concrete slab foundations and install 13 AB Chance helical anchors and new concrete foundations, all completed to my full satisfaction

Maloney Construction came through for us when our home was in danger. The footings on our deck were slowly, but surely slipping down the hill!

Sean was able to put together an all inclusive package from design through completion of construction which was affordable and allowed the process move quickly and smoothly. Now we can feel confident that, when we sit on our deck and enjoy BBQ's with friends, We are safe and our home is Secure.

Thanks Sean, and Maloney Construction!
