"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 many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.
