"John Phillpis Construction (JPC) was a great find. First, he was recommended by my Real Estate broker. That’s a plus BTW. JPC started by fixing a consistent leak in a downstairs below ground bedroom. It wasn’t an easy fix. His men had to dig a trench the entire length of the house. Install drainage pipes and stuff like that. It never will leak again! ... Then they fixed a wall I had to crawl around for 9 years. But on simple jobs he works alone. Like buying and installing 2 new fans from Home Depot, a Samsung TV from Amazon and dumping 3 junk TiVo’s. Today, he fixed bathtub fixtures I couldn’t get anyone to fix for 8+ years. He found the American Standard(?) valves in an outta the way plumbing store in the boonies. After visiting 2 better known places. The tub/hot tub works now ... finally! No cutting tile or replacing $500 fixtures! I have a long list of jobs awaiting... I’m glad I found John Phillpis. I hope this helps"

"We needed a new roof 26 years after MRC had last done our roof. We worked with Mark Hill to find a roof coating that would cool our house. He recommended a product called Permalock Metal roofing and a silicone coating for our flat roof. We have had the roof for 1 year and this summer has been nice and cool. Thank you to the team at MRC."

Basement Waterproofing questions, answered by experts

In Honolulu, expanding water stains, cracks that grow, or spreading salt deposits on basement walls signal worsening foundation moisture. Persistent mold, increased termite activity, or wood rot are red flags for escalating water damage. If you notice slow-draining standing water or soil erosion near your foundation, these minor issues can quickly become major basement waterproofing concerns in HI’s humid, storm-prone climate.

Helpful?

In Honolulu, start each dry season by inspecting and cleaning gutters, checking for new cracks, and testing sump pumps to prevent water damage. During rainy months, monitor for leaks and foundation moisture monthly, documenting any changes. After storms, inspect for signs of flooding or mold. Use the dry season for repairs and upgrades, and secure drainage systems ahead of hurricane threats for optimal flood prevention.

Helpful?

In Honolulu, you can address minor basement waterproofing concerns by ensuring gutters and downspouts are clear to prevent foundation moisture. Adjust landscaping to direct water away from your home, and use a dehumidifier to combat HI’s high humidity. For small cracks, apply hydraulic cement suitable for salt air exposure, and consider installing a vapor barrier to reduce water damage risks, especially during hurricane season.

Helpful?

In Honolulu, the success of basement waterproofing depends on using materials resistant to salt air and volcanic soils, as well as proper installation during dry weather. Thorough surface preparation and regular maintenance are crucial for preventing water damage and foundation moisture. Integrating effective drainage systems and addressing repairs promptly helps ensure long-lasting protection, especially considering HI’s high humidity, frequent storms, and risk of flooding.

Helpful?

In Honolulu, signs you need basement waterproofing include persistent dampness, musty odors, or water stains after heavy rain. Look for efflorescence (white deposits) on concrete, cracks wider than 1/4 inch, or visible mold, which can indicate foundation moisture issues. Scheduling work before the rainy season or after a tropical storm helps prevent water damage and protects your home’s lower levels.
